▼ This thesis presents the potential of solar energy to answer the increasing demand for sustainable energy. Multiple floating solar parks are installed on inland water bodies. This trend is a result of the lack of surface for PV systems and a result of legislation on national and international governmental levels, for the reduction of greenhouse gasses. This inland technology is currently well established. Still, in densely populated areas such as the Netherlands supplementary surface could be beneficial to unlock the full potential of solar energy. Ocean and sea surfaces are a possible, but challenging solution to this problem. These offshore water surfaces could be used for electricity or synthetic fuel production. Offshore locations are attractive because of the abundant availability of surface. Still, an OFPV-system needs to overcome multiple technical and non-technical challenges and requirements. This challenge demands technical solution within the constraints of a suitable business case. Furthermore, the impact on people and ecology also needs to stay within ethical borders. An OFPV can be subdivided into three physical subsystems: an energy converting system, a position monitoring or mooring system and a floating support structure. Multiple concepts were proposed in literature or by the industry. All proposed concepts are variations of support systems that provide a surface for conventional PV-technology. It also was concluded that none of the proposed concepts is fully developed. Currently, only one system is in the testing phase. The current state of the technology, and the high potential of an OFPV are the drivers behind the search for a new concept design. In this thesis, the requirements for an OFPV support structure were formulated, and a brainstorm resulted in the buoy and beam concept for further research. The buoy and beam structure is a system in which submerged beams form a triangle grid are held together by floating buoys. The buoys support triangle platforms, by carrying the corners of the platforms. All connections between the buoys, beams and platforms are fully hinged. Because of the hinges, the structure can move with the waves and therefore mitigates the loads it experiences. In the second part of this thesis, the feasibility of the buoy and beam structure was assessed. It was concluded that the heave response is the most critical response to the feasibility of the concept. When the platform would heave too much, the waves will slam into the platforms and the solar panels, leading to damage and excessive loads on the structure. Consequently, the heave response and the relative wave height seen from the moving triangle platform are researches and modelled. The structure was identified as a hydrodynamic transparent structure. Consequently, the relevant hydrodynamic loads are obtained with the Morison equation and Airy wave theory. All damping terms are linearised. A differential equation incorporated the constrains for both, the construction and the hydromechanic loads. The mechanical equations… Advisors/Committee Members: Schreier, Sebastian (mentor), Hopman, Hans (graduation committee), Delft University of Technology (degree granting institution).

▼ Two important trends can be witnessed in the world of superyachts. Firstly, the luxury landscape is shifting from collecting tangible assets to pursuing exclusive tailor-made experiences. The second trend is the electrification and the use of batteries on superyachts. Due to the increase of emission restrictions, there is more interest towards battery-powered yachts. During the Monaco Yacht Show of 2016, Feadship presented their answer to these trends: a unique multibody superyacht concept by the name of Choice. A multibody superyacht is a combination of multiple yachts, including at least one superyacht, and designed around positive involving interaction. In the case of Choice, this interaction enables a combination of three bodies, of which one solely propulsed by batteries, to sail long distances. By the means of interaction, the weight of the batteries are kept within reasonable amounts. Besides the previous features, the multibody creates significant more flexibility and possibilities for its use. On the contrary, sailing with three interacting bodies instead of a conventional yacht could use more energy. At the moment of writing, there is no such multibody concept sailing the seas. Therefore this thesis analyses a range of multibody superyacht concepts by comparison of total energy consumption. To gain more understanding of the multibody superyacht usage, a fictive itinerary is designed. This also functions as a business case for the concept design boundaries and the energy consumption comparison. Different multibody superyacht concepts are created within the boundaries of the design space. By splitting the design space into two parts, i.e. the multibody design space and single body design space, the process is kept comprehensible. All concepts have an equal overall functionality, measured by the available luxury area. The difference between the concepts is found in the way of distributing the area over the three bodies within each multibody concept. The battery propulsion could be fitted in either, or multiple, of the three bodies. Different possibilities concerning the location of the batteries are assessed too. When designing the single bodies within the multibody concepts, a challenge arises. Due to the weight of the required batteries, the single bodies within the multibody are heavier than their conventional fuel powered counterparts. To compensate for this weight, the bodies size is increased, while maintaining the predefined functionality. Due to the size increase, more engine power is required. Consequently, the battery capacity should increase, resulting in more weight. This thesis proposes a design tool for the single body to solve this iterative process. If the designer provides information on the functionality and usage of a yacht, the design tool calculates the main dimensions of a single body concept. The functionality of a single body is predefined by six yacht types and functions as design tool input. Other input is derived from the business case.

▼ Yachts are built to provide guests with a unique experience. In order to provide this experience, yachts are often anchored at special locations. Captains prefer to use a single bow anchor when they moor the vessel. Problems are reported with respect to the availability while yachts are at anchor. These are caused by environmental forces. Availability is the yachting term for the operability of a yacht. The comfort on board and the availability of activities are the main aspects playing a role in the overall availability. Horizontal motions and accelerations of the vessel, respectively caused by wind and waves, are the main issues at anchor. These undesired accelerations can be reduced by controlling the yacht’s heading, ensuring optimal wave interaction. The objective of this research is to improve the availability while at anchor by suppressing the horizontal motions and controlling the heading of the vessel. Previous research suggests that using thrusters is a feasible solution for this. The research performed in this thesis provides a design proposition based on a quasi static analysis. For that reason, mathematical models are developed which are embedded in engineering tools. When these tools are defined, the first step is a parameter study. This has been performed to examine what, theoretically, is the preferred anchor support system. In this study, the required power and mooring force is calculated for a predefined capability. The capability is the environmental condition at which the system is able to be stationary. Based on the results can be concluded that the mooring line has to be located close to the pivot point of the vessel and that the thrusters have to be located with a large distance to the pivot point opposite to the mooring line location. Using multiple thrusters is often preferable because the same thrust can be delivered with less power. However, the thruster located the closest to the mooring line and pivot point delivers little thrust compared to the other thruster located further away. The usage of a tunnel thruster or an azimuth thruster is preferred. The difference between these two is limited because the azimuth thruster operates at an angle θ of 90 degrees. The theoretical solutions found neglect practical aspects which have to be taken into account for implementation; e.g. the layout of the vessel and the range of the required headings. To consider these aspects, multiple assessment criteria have been defined. The design study has been performed with various design cases. The capability of these cases has been calculated with the developed model in terms of wind speed. When the used power is reduced, the comfort with respect to noise is increased. However, this reduces the capability as well because less thrust can be delivered. The reduction of the capability is related to the power margin to the power 1/3, when the thrusters are operating at maximum allowable power. For each design case, the dynamic positioning capability has been calculated to investigate… Advisors/Committee Members: Hopman, Hans (graduation committee), van Geer, B.J.

The international maritime sector accounts for about 2% of all global carbon dioxide (CO2) emissions, the main greenhouse gas that causes global warming. Nations meeting at the United Nations International Maritime Organization (IMO) in London have proposed an initial strategy for the reduction of greenhouse gas (GHG) emissions from ships, setting out to reduce GHG emissions from international shipping by phasing them out as soon as possible with the aim to achieve zero emission by the end of this century. Heerema Marine Contractors (HMC) is a world leading marine contractor in the international offshore energy industry and aims to be a role model in environmental responsibility through carbon emission reductions. As a result of HMC’s global activities, their fleet covers a considerable distance through transit across the globe. Their large semi-submersible crane vessels are conventionally transported through towing by a tug. The great amounts of fuel required for these transits provides a significant opportunity for the reduction of HMC’s carbon footprint. One such initiative proposed within HMC is the application of wind-assisted ship propulsion on the tow configuration. This report presents an initial investigation of the feasibility of wind-assisted towing of the HMC’s Thialf, a semi-submersible crane vessel. Previous internal research at HMC showed the feasibility of using a discarded Panamax vessel as a floating breakwater. While operationally the discarded Panamax was found to be feasible, economically this was not the case. In this research, using the Panamax as a wind-assisted tug for towing the Thialf is investigated. As such the Panamax vessel can be employed for multiple purposes; for wind-assisted towing and as a floating breakwater, improving the financial feasibility. To test the performance of a wind-assisted tow operation, a comprehensive 2D model is developed in this research to be able to check configuration variations in a wind-assisted tow setup. A conceptual design of a Panamax vessel converted into a sailing tug is implemented in a 2D model simulation. The performance in combination with the Thialf is assessed under the common environmental conditions experienced by the Thialf for various transit routes. Results showed that the use of a wind-assisted tow configuration based on a Panamax, without using the Thialf propulsion is not feasible. The main point of failure is the required force balance transverse to the sailing direction. The Panamax basis used for the preliminary wind- assisted tug design proved to be not the optimal base case due to the limited leeward force generation under a drift angle and the large sensitivity to environmental loading. Although implemented measures improved the systems performance, it is debatable whether a wind- assisted tow configuration with the associated uncertainties is the most promising area to accomplish significant CO2 reductions.

Trim optimization is an approach considered by the industry to improve the energy efficiency of ships, having a potential in both reducing operational costs and to decrease the emissions of the ship. Potential fuel consumption reduction by trim optimization is 0.5 to 3 % and to up to 7% in extreme cases. Stolt Tankers, a shipping company active in the chemical tanker market, wants to increase the energy efficiency of their ships in operation by trim optimization. For a limited number of ships, trim tables from model scale towing tests are available, but these are not used and the accuracy of these tables are unknown. The objective of this research was to develop a method to decrease fuel consumption by trim optimization, by a dynamic fuel consumption estimation model based on available operational data, that can be integrated in the voyage management system of Stolt Tankers. A dynamic fuel consumption estimation model has been developed, using mainly the noon report data of the C-38 ship class, consisting of six sister vessels of 38 000 DWT chemical tankers. Quality of noon report data is an issue: human error in observing and recording data causes noise and a mismatch exists between the snapshot of conditions on one hand, and the 24 hr averaged sailing speed and recorded shaft power or fuel consumption on the other hand. A data pre-processing framework has been developed and applied to integrate and transform the data, clean and filter the data. The model is able to extract the effects of speed through water, mean draft, trim, sea water temperature, wind force, sea state and swell state and their relative direction to the ship and days since last hull cleaning and propeller polishing. The model has shown to perform optimal using the regression model of Lutzen and Kristensen (2013), combined with a multiple layer feed-forward neural network, consisting of 1 hidden layer with 15 neurons. The model is able to estimate the shaft power with an average accuracy of 6.58 % for a random test set of the noon report data. It is able to extract the effect of trim on shaft power and to consider the effect of weather and fouling conditions. Model results show that about 1 to 2% of shaft power per 0.50 m can be saved, with trim by bow being the optimal trim. Based on sea trial results, it is concluded that the model performs most accurate for conditions that are represented by a high quantity of historical data. The model can be applied for speeds between 12 and 14 knots and for mean draft conditions of 9.5 m and more. Within this range, the effect of trim and weather conditions are followed with reasonable accuracy. It is confirmed by the sea trial that trim by bow is the optimal trim, with a much stronger magnitude of the effect of trim on shaft power. A difference of 6 to 8% in shaft power was found for a change in trim of 0.50 m.

▼ The negative effects of global warming can already be noticed. The burning of fossil fuel not only contributes to global warming, but also to the reduction of air quality, especially in urban areas. In order to limit the climate change, as well as to improve the air quality, more and more vehicles are replaced by emission free versions. This thesis is a case study in which the feasibility of replacing a fast passenger ferry (300 passengers, 30 knots) by an emission free vessel was investigated. Two options remained after analysing different methods of emission free propulsion: battery powered and hydrogen fuel cell powered, both in combination with an electric motor. So in this report, the emission free ferry is an electric vessel. Without additional design changes, a battery powered version is not possible. So a reduction in energy consumption is required. A hydrogen powered ferry is feasible, but more expensive, thus a reduction in energy consumption is desirable as well. It must be mentioned that costs is not the most important aspect, because the reduction in emissions might be worth it. Furthermore, a lot of indirect costs are related to pollution. The effect on energy consumption was analysed for three design related changes: elongating the hull, using carbon composite instead of aluminium, and applying expected future battery and fuel cell systems. Currently, a battery powered ferry is only feasible with an elongated hull, but future technology significantly increases feasibility, also for the original hull length. A reduction of structural weight also increases feasibility, which effectively means a reduction in costs. The hydrogen powered ferry was already feasible, but the above mentioned changes in design improve feasibility, i.e. reduce the costs. Two operational changes were analysed as well: operating at a lower design speed and operating on a shorter crossing. The first has a limited effect on energy consumption, but the latter significantly increases feasibility of the battery powered ferry. Both changes do not have much effect on the feasibility of the hydrogen powered concept. The final concept that was analysed is the hydrofoil supported catamaran, because hydrofoils can significantly reduce resistance. Compared to existing hydrofoil vessels, there are two major differences: the electric concept has relatively more weight, and its design speed is significantly lower. Therefore, the hydrofoil must be relatively large to generate the required lift, and a larger hydrofoil suffers from larger 3D and interference effects. This drastically lowers the efficiency, and as a result, the hydrofoil concept is not a feasible solution. It can be concluded that an emission free fast ferry is feasible. A battery powered ferry is best suited for short crossings and the hydrogen fuel cell powered ferry can operate at longer crossings. The direct costs are likely to be higher, but this might be worth it, as it leads to a reduction of emissions, and thus to a reduction of indirect costs related to pollution.

▼ The amount of international shipped cargo grows steadily, and seas are exploited for seabed mining and energy production more than ever. As a result, there is an increase in traffic density and decrease in free navigational space, potentially causing a higher incidence of dangerous navigation situations that may lead to ship collisions. This thesis establishes a hypothesis that there are coastal areas where the risk of collision is unexplored and abnormally high and has not been analysed yet. Therefore, the thesis aims to develop a method suitable to assess the risk of collision in coastal waters. A thesis literature review primarily focuses on the current collision risk assessment methods, circumstances of collisions, and sources of navigational information for coastal waters. The literature review concludes that a promising and novel approach is to detect near-collision situations based on the data from the Automatic Identification System (AIS). The near-collision exists when a ship's safety domain is violated and, simultaneously, the ship performed a last-moment evasive manoeuvre, which is identified by an abnormal ship's rate of turn. Building on a previous basic version of the near-collision detection method and AIS data provided by Safetec Nordic AS, this thesis develops a collision risk assessing tool that significantly outperforms the original method. The performance of the designed method was evaluated using AIS data from the Vestfjorden area in Norwegian coast during 2013-2015. The case study shows that this approach effectively detects near-collision situations but identifies a considerable number of new false near-collisions. The details and spatial distribution of detected near-collisions provide valuable insight into navigational areas vulnerable to collisions, collision circumstances, and frequency of collisions.

Five naval support vessels are being replaced. For this replacement two focus points are important. The first one concerns creating more unity within the fleet, achieved by using the hull geometry as a monolithic part. The second one concerns the aim to reduce harmful emissions by reducing the effects of the energy transition by minimising the resistance of the vessels. The current design approach at DMO has deficiencies which limit the ability to vary hull forms and to analyse a large set of design options. Also propulsion power is predicted by regression lines only, which makes it difficult to evaluate novel hull forms. Motion predictions are only used in a later design phase. These deficiencies need to be resolved. The technological opportunities which will be used to address these deficiencies are incorporating CAESES and RAPID in the concept exploration phase. CAESES is a CAD method with integrated optimisation algorithms which makes it useful to make hull form variations by using parametric optimisation. RAPID is a potential flow solver which can be used to predict the wave resistance on the geometry. The total resistance will be predicted by using Holtrop and Mennen for the viscous resistance components. The seakeeping capabilities are predicted by a simplified version of the linear strip theory. The main objective can be formulated as: How can the unity and the energy transition be analysed in the concept exploration phase for the new generation naval support vessels with a hull geometry point of view using RAPID/Holtrop/seakeeping integrated with CAESES Four validation studies have been performed. The test case studies are analysed on the differences in effective power and vertical displacement. The first conclusion is that the effective power will increase for a family design strategy in comparison to a single ship design strategy. The second conclusion is that the vertical displacement can be decreased when using a family design in comparison to the single design strategy. But only when the Logistic Support vessel is left out of the family of vessels, because of its restricted length. The design speed can be used as a design variable, but only when a more sophisticated power usage objective is used. The new approach can be very useful in the concept exploration phase at DMO. The new approach uses a more advanced resistance objective in combination with hull variation. It can also predict the seakeeping capabilities in the concept exploration phase already. The integration of a potential flow solver and prediction on vertical displacement at the bow can be done within one optimisation and a study is possible within reasonable time (under six hours). This makes the new approach practical in the concept exploration phase.

During the early stages of ship design exploration, design freedom is abundant but problem knowledge is scarce and most costs are already committed. This amounts to an incentive to look at the influences of the requirements on a design, to better understand how a concept is defined. This thesis investigates the operational architecture concerning how systems are used (often in a temporal fashion). A way to quantify the operational architecture is with operability, which describes the ability of a ship to perform its mission. This thesis identified the system performance consisting of availability and vulnerability part of operability as its main topic. Markov theory was selected to assess the availability of systems in order to maximize the operability of a naval vessel. Transition rates of systems are a key element of Markov theory but are hard to obtain during Early Stage Ship Design. A network-theory-based approach allocated nonquantifiable focus points to each system to determine their importance within a network. These were then linked to transition rates, which are required for a Markov chain to calculate the availability of a system. Four case studies were performed to test the model: several configurations were compared, two different focus points approaches were used, different ranges of rates were applied, and systems were added or subtracted. The model proved to behave according to educated guesses beforehand but also gave new insights in connections between nodes. The eigenvector centrality approach used to allocate focus points was found to be better than the combined connectivity approach. The scale of the ranges of rates should not result in very high values for system availability since they do not provide data which makes comparisons between network configurations possible. Very low values of system availability were deemed too far off from real-life values. This thesis paves the road towards a total assessment of operability. It has focused on the availability of systems, and delivered a method to make preliminary decisions for systems design in the early stages.

When your dream yacht is being built at Feadship, the process starts with a blank page. This early stage is defined as the Sales phase. In consultation with a designer, the look and the feel of a yacht is easily captured. The expertise of the designer will lead to a yacht fitting the vision of the client. In the current process, the lines drawn on paper restrict the design freedom of the naval architect. Next, not all consequences of decisions are known, which leads to the probability of alterations in later phases. The current design method is called a point-based method. A single starting point is chosen, which is gradually refined in a couple of iterations. This method has some disadvantages. Design exploration is a method in which many solutions are generated in a design space and no single starting point is chosen. The main focus of this approach is to postpone the design decisions until they can be made with the required knowledge. This will prevent alterations and rework in future phases. In this research, there is investigated whether design exploration could be implemented in the Sales phase at Feadship, using design drivers for the exploration method. The design driver origin from the stakeholders (client, regulatory bodies and Feadship) and are used to structure the design requirements and to evaluate the solutions. Creating the design space is done with help of a simple Design Model. Due to the limitations of the Sales phase this model is built with help of regression lines, empirical formulas and rules of thumb. The set of solutions are explored with eight design drivers which originated from the stakeholders and Sales process: Aesthetics, Usage, Performance, Rules, Costs, Space, Comfort and Safety. The design drivers are categorised into three parts: input, constraint and output. The input will follow from the client, where the constraints will follow from the other two stakeholders. The final choice for the output is made by the client, which can be underpinned with help of the output design drivers. This research concludes that design exploration could be an improvement on the current used point-base design method. Since design exploration fully utilises the design freedom available in the early stage design. The solutions produced by the Design Model show reasonable results, which lie within a 10% margin of the existing designs. Due to the limitations of the Sales phase the choice was made to use regression lines. As a result, the design space consists of solutions of which the trend is clearly visible. Nevertheless, the variety within the design space is sufficient enough to create a diversity in solutions. The results produced by the Design Model will be a good starting point in the starting phase. In order to use the results as more than a starting point, the detail level of the calculation methods should be improved. Generating a set of solutions will enable the designer and client to make well-informed decisions. Especially when the client is involved in this process.

▼ Constructing the general arrangement of a ship tends to be a very complex naval architectural problem. There are multiple systems that all work integrally. Some of these systems need to be placed together, others need to be separated and some systems probably need to be both at the same time for different objectives. The preliminary ship design phase is all about finding the balance between these objectives and possibilities within the arrangement. Automated general arrangement generation methods, such as the TU Delft pack- ing approach and IECEM, have created an algorithm and methodology that are able to generate thousands of feasible ship designs corresponding to the desired requirements. These approaches combine a bin-packing and a genetic algorithm in order to create a diverse set of possible designs. Although optimisation approaches can efficiently generate and search for a set of designs, it can not automatically select a design, van Oers et al. (2008). Out of the cloud of generated designs, choosing and evaluating those designs that are of most interest seems to be a more difficult task, DeNucci et al. (2008). Human rationale deems necessary to decide what properties of an arrangement can be analysed as “good” or “bad”. Using computational force to assist with design selection based on qualitative properties needs a way of capturing this rationale, which is demon- strated by DeNucci. Subsequently, this captured knowledge needs to be applied in a methodology to actually analyse the data by this rationale. Design selection of computer generated arrangements is currently based upon performance parameters fo- cusing on numerical characteristics of the designs. Spatial relations within the interior layout can now only be manually analysed, which is merely possible for a singular design. This results in a lack of understanding of spatial and physical relationships, or qualitative properties, within the designed arrangement. This thesis proposes a method that is able to quantitatively compare these qualitative properties by creating a measure of effectiveness of the interior layout, or arrangement, of the designs. This is done by creating a simplified representation of the 3D arrangements using network theory. By converting system objects and connections of these systems into nodes and edges, a mathematical net- work description of the arrangement is possible. Using eigenvector and betweenness centrality measures, rank and weights are given to these system objects. Design rules based upon rationale captured by DeNucci are set up and used to analyse connections between these systems. A scoring algorithm is created that is able to combine the ranks of the systems with the captured rationale to give a singular performance parameter, or measure of effectiveness of the interior layout characteristics of the designs. Application of this method to a data set of small cruise ship designs shows the capabilities of this methodology and the ability to quantita- tively compare the qualitative properties of… Advisors/Committee Members: Hopman, Hans (mentor), Kana, Austin (mentor), Akkerman, Ido (graduation committee), Delft University of Technology (degree granting institution).

▼ Autonomous sailing is considered by many to be the next big thing in the shipping sector. Many companies, including Rolls Royce and DNV are investing heavily in research that helps in the development of autonomous shipping. Most research is currently being done regarding autonomous navigation, communication and cyber security. What is often neglected in these studies is the need for maintenance within the engine room. With all ships having multiple crew members solely dedicated to keep the engine room going, their absence will have a big impact on the design of engine rooms. This paper aims to find what equipment will become a weak point in engine rooms once these are no longer occupied and maintained by crew members, and how these weak points can be eliminated. With the absence of reliability data that corrects for maintenance and crew interference, this paper tries to find these weak points by analysing crew member behaviour. It is assumed that if a crew members spends more time on equipment, or deals with it more frequently, then that piece of equipment is less reliable. In order to find what equipment can be seen as a weak point, a redundancy reduced risk index was created. This index is a combination of the frequency index, which states how often engineers spend time on equipment, the severity index, which lists the consequences of failure for equipment, and the redundancy index, which is dependent on the level of redundancy of components. The redundancy reduced risk index is split into three levels: low, medium, and high risk. Medium and high-risk components were considered weak points, while low risk components were not. For all high risk and for most medium risk components, solutions were generated which will reduce the risk index of the components or system overall. For some components, the risk was deemed acceptable, as any solutions would be too costly to justify the risk reduction. Solutions were split into two categories: specific solutions, which were all catered to specific components, and a bulk solution, which was the installation of a second drive train. A second drive train would include a second main engine, gearbox, propeller and rudder. With the solutions found, the two categories were subjected to a financial analysis to see if they are commercially viable. The solutions were applied to ships of four different sizes, ranging from a 6,000 GT feeder to an 85,000 GT capesize bulk carrier. For these ships, the OPEX were calculated and divided into four categories: Operational costs, fuel costs, capital costs and crew costs. The initial investment for the machinery plant was also calculated. This was the basis to finding the increased cost for solutions found in this paper. Using these specific solutions, the machinery plants will become roughly 50% more expensive, while adding a second drive train will increase the machinery cost by 110%. It is assumed that these solutions will eliminate the need for a crew and therefore eliminate all crew costs. Using these figures, it was… Advisors/Committee Members: Hekkenberg, Robert (mentor), Hopman, Hans (graduation committee), Veeke, Hans (graduation committee), Delft University of Technology (degree granting institution).

▼ This thesis discusses the concept development of a 90 meter Yacht Support Vessel (YSV) with the help of TU Delft Ship Synthesis Model (SSM) called packing. Speed, together with a considerable amount of demanding and conflicting characteristics, such as: the capacity of storing two helicopters and at the same time being able of taking around large and bulky tenders, are crucial aspects of this type of ships. Damen Shipyard, leading this market, collaborated to this study. In particular, the object case-study would ideally represent the flag-ship of the gamma for the shipyard, emphasizing and taking to extreme all this type of ship features. In addition, the vessel should provide storage for spare parts and provisions, accommodations for extra-crew and staff but also have fully dedicated guest areas. This work discusses the aptitude of the packing approach of dealing with this particular ship design problem. The methodology developed by TU Delft can rapidly generate a large and diverse set of thousands of different feasible low detail ship designs. The dissertation is composed by two main parts: the first one is focused on using this methodology to develop a diverse design space to explore various possibilities before converging on a selected few to further define later in the thesis. The second part provides the elaboration of the most promising design picked up in the first phase. The packing-based ship description consists of five elements (objects, positioning space, overlap rules, design changes, packing process) representing the Ship Synthesis Model (SSM) that together enable the description and parametric variation of a ship during early stage design. By creating multiple feasible design solutions, the task of the naval architect is focused on analyzing, evaluating and deciding rather than creating different options. Thus, it is proposed to study the feasibility of multiple different options and, by analyzing the more relevant conflicts, it will be possible to drive the choice towards the most promising design. In this work are highlighted the design decisions undertaken by packing on the options modeled, comments and explanations are given on the rationale that helped in cutting the design space represented by thousands of different design concepts. Consequently, it is illustrated how the down-selection from a multitude of options to only few solutions was carried out. The most promising design is improved through some of the steps typical of the ship design spiral with the aim of satisfying the imposed design requirements. Several rounds of the ship design spiral are undergone bringing gradually to the final outcome. These successive steps led to the fulfillment of all the non-negotiable requirements set in the design brief, successfully developing the 90 meter concept. The description of the main characteristics of the ultimate design closes the second phase of the thesis before conclusions and reflections… Advisors/Committee Members: Hopman, Hans (mentor), Kana, Austin (graduation committee), van der Velde, J (graduation committee), Delft University of Technology (degree granting institution).

▼ The past decade the packing approach was developed at the TU Delft. This tool automatically generates tens of thousands of ship designs in order to fully explore the design space. This is opposed to the traditional way of ship design, where just a limited number of designs can be elaborated. The result is a set of ship designs that can be used both to obtain initial sizing parameters of the ship, and to relate the impact of design decisions on performance characteristics. It is questioned whether resulting sets of designs really contain tens of thousands of different ships, or just a couple of really different ships that have only minor variations. It is thus questioned whether such a set of ship designs can be divided into families. This is investigated in this thesis. In order to attack this problem in a generic fashion, the ship designs were approached from a numerical perspective. It was found that in the field of data science, clustering algorithms exist which are devoted to find clustering structures in data. Therefore these techniques, such as PCA and k-means, were applied to data at hand. In a test case this method is applied to divide the set of designs from a mine countermeasures vessel into families. First it was questioned whether families could be used in order to assess the survivability of machine systems of these ships. The resulting families matched the families regarding the position of the gun, which were already known upfront. Although these families are not sufficient to fully assess the survivability of these ships, this analysis showed that most probably no other structure is present, stimulating more straightforward definitions of families. In a second test case the same MCMV was divided into families regarding the layout of the designs. It then appeared that the dataset at hand was built by ten distinct runs of the packing approach which were combined to this one total set. The method showed that it could be pointed out, just by looking at the designs, which design was generated in which run. This showed that the dataset might not be as diverse as it seems. Since it is the core idea for the packing approach to explore a big part of the design space, thus generating a diverse set of ship designs, this motivates new research to tackle this issue.

▼ In April 2018, the International Maritime Organization (IMO) agreed upon the target to reduce the CO₂ emissions from international shipping in 2050 by 50 percent with respect to 2008 levels. The strategy to reach this target consists of the ambition to reduce CO₂ emissions per transport work, as an average across international shipping, by at least 40% by 2030, compared to 2008 levels. However, due to uncertainties involved in the decision making on the implementation of CO₂ reducing measures, shipowners are uncertain which actions to take regarding their existing fleet in order to deal with those upcoming requirements. For rail transport, road transport and inland waterway transport, TNO has developed the Multi-level Energy Optimization tool (MEO). For these modalities, MEO is capable of calculating the CO₂ emissions for a certain voyage and assessing the effect of CO₂ reducing measures on the carbon footprint of those voyages. The objective of the research presented in this report is to extend TNO's MEO tool with the maritime modality and develop a tool supporting shipowners in the decision making process regarding the pathway of implementing CO₂ reducing measures in sea-going vessels. The tool presented in this report is developed to meet this objective and is based on a Markov Decision Processes (MDP) model. The MDP method has the ability of optimizing a time dependent decision policy in the face of uncertainty. In this case, the optimal policy resulting from the MDP model is optimized to obtain the highest cost savings by implementing CO₂ reducing measures. For the input of the model, the vessel has to be described by an operational profile and the vessel and engine specifics such as a speed-load curve and the propulsive efficiency. Also, the environment has to be described by fuel properties, economical parameters and a regulatory framework. With this input, the MDP method can assess the optimal policy regarding the implementation of a set of CO₂ reducing measures with the objective of minimizing costs. The output of the tool consists of the expected values of total costs, CO₂ emissions and CO₂ efficiency for when the optimal policy is followed, in comparison to maintain the business as usual. To put this tool in practice, a case study has been carried out on a 93000 DWT bulk carrier of which operational data has been provided by the shipowner. A data analysis on the daily reports of the vessel has been done to obtain the values for the vessel input and literature has been used for the environment input. The optimal policy for a set of measures is assessed and the influence on the results by varying fuel prices, the regulatory framework and the dry dock schedule has been studied. The key result of the case study is that with the implementation of several fuel saving measures and a dual fuel engine the total costs with respect to maintaining the business as usual is expected to be… Advisors/Committee Members: Hopman, Hans (mentor), Kana, Austin (mentor), Harmsen, Jorrit (mentor), Atasoy, Bilge (graduation committee), Delft University of Technology (degree granting institution).

The subject of this master thesis is the development of a design tool to help Vuyk Engineering Rotterdam B.V. arrange the machinery spaces (engine room, switchboard rooms, separator rooms) aboard their vessels early in their design process. It applies the field of automatic design generation to a step in Vuyk’s design process to save time and easily explore alternatives. First the general design process at Vuyk and the design of the engine room and other machinery spaces in particular are investigated. This is followed by a review of literature on design of machinery spaces, both in maritime applications in ships and in non-maritime process plant lay-out design, to compare theory and practice at Vuyk and look for new insights. Next to the design process itself, the characteristics of ship concept design tools are investigated in literature, leading to a focus on concept exploration and various methods how to deal multiple objectives. This results in the design requirements for the design tool for machinery space arrangements and a focus on the most relevant requirements to consider in the limited time frame of this thesis, to limit the scope. The best modelling method and resolution approach for the problem are investigated. The Facility Layout Problem and Particle Swarm Optimization algorithm are identified as the best options. The model is defined accordingly. The capabilities of the model for the design tool are tested in a concept design of a jackup vessel. Initial runs of the model led to problems for the Particle Swarm Optimization algorithm, as its gets stuck in local minima while trying to solve the problem. This severely limits the solutions diversity. Several adaptations for the model are developed to overcome this problem. The particle swarm algorithm is adapted with several mutations, allowing it to better escape the local minima thus creating more diverse, better optimized solutions. The model is also improved with an additional grouping constrained and a pathing filter to better account for the identified machinery space design drivers. The resulting tool is applied in a case study on the early concept design phase for a dredge pump room and connected engine room for a trailing suction hopper dredger. The tool is used to evaluate early design choices in space arrangements for a diesel-direct drive of the dredging pump and jet pump, in comparison to alternative diesel-electric solutions with three V16 diesel-generator-sets, four V12 sets or six V8 generator sets. The application of the tool leads to valuable insights for the arrangement options for the machinery spaces. The developed tool is shown to be a useful addition to the early concept design of machiney space arrangement.

Small scale inland shipping, especially in the case of transported containers, is used only marginally compared to its capacity. The small inland waterways have abundant capacity to accommodate up to 700 percent more transport. On the other hand, road based container transport is cause for external damages in the form of congestion, emissions and accidents. All that are of course unwanted. To reduce the overall external damage (monetized into cost) for container distribution a modeshift from truck to small scale inland vessel is worth promoting. This thesis researched the feasibility of designing radically renewing small scale container distribution concepts for both vessel and inland terminal. A scalable container carrier concept series is designed and tested for feasibility. Goal of the concept vessel was to design a dedicated series around its cargo, the container. Existing inland vessels of smaller dimensions have holds of suboptimal dimensions, resulting is excess cost. In parallel with the vessel series a scalable container terminal concept has been designed and tested. Goals for the terminal was autonomous operation and low cost per move as existing terminal fail to operate on competitive cost levels for low volumes. The results showed outperformance of competitor alternatives and economic feasibility for both concepts. Results of a case study show the possibility to ship and transship containers to more local, rural terminals at competitive costs levels. Meaning substantially below the costs of existing competition. In addition is the local terminal allocation leading to penetration of the inland waterway network’s capillaries. As a result, shorter pre- and post-haulage operations by truck are required. This increase in sailing distance share and decrease in haulage distance reduces the overall external cost of transport for those specific containers.

▼ At Damen’s Research and Development department, continuous improvements are made to existing design practices using recent technological developments and fatigue design is currently on the anvil. High speed craft operating around the globe are subject to millions of load cycles (resulting from ocean waves) and therefore suffer from metal fatigue. As per current practice, such vessels are designed for fatigue using inhouse software with a nominal stress approach supported by static sea-state scatter data and judgement based operational profiles. Recently, new data sources with real time sea-state data over the whole globe have come available, including GPS locations of ships. Together, this enables it to generate real time operational profiles for its ships. A total stress concept has been developed based on results from a JIP called VOMAS. This approach has shown to provide accurate fatigue lifetime estimates for arc-welded aluminium joints. Similar results are expected for steel joints as well. The main goal of this thesis was to explore possible improvements for the fatigue design methodology. A tool called Tanaav was developed for this purpose which makes use of both remote monitoring data and the total stress concept and provides an estimate of the yearly fatigue damage and fatigue lifetime. The tool has been used to predict the fatigue lifetime for three fatigue sensitive details in 46 FCS5009 vessels. Results have been compared to corresponding predictions using current and past fatigue analysis practices. It was observed that using both remote monitoring data as well as the total stress concept provides significant improvements in the predicted fatigue life time. Uncertainties in fatigue influence parameters affecting the predicted fatigue damage can be incorporated using probabilistic. This thesis proposes a method for this and presents two cases as a proof of concept. Work done in this thesis will be validated by Damen in future with the help of full-scale testing on an actual FCS5009 vessel during an offshore measurement campaign. After validation, this method will help in improving fatigue design practice, increasing design flexibility and in optimizing vessel weights in a responsible way.

This thesis investigated the possibility of alternative ways to loading and offloading flexlay vessels and provides a concept design. This was investigated because currently, the vessels designed by IHC, have to sail back to port to restock on pipes. During this time the expensive pipelayer is not laying pipes and thus not making money for its operator. Some operators have already moved to designs which use cranes to load pipes at sea. However, lifting heavy objects results in limited operability and wide vessels. The problem owner (IHC) wants to avoid this. The goal was to find a way to transship pipes offshore, which improves on the current performance of the reference vessel without resorting to cranes to transfer the pipes. The research was mainly focused on the modelling of the logistical process of getting pipes from the port to the location. The results of this were used for the conceptual design of a flexlay vessel capable of being supplied at sea. The reference vessel built by the problem owner turned out to be a suitable candidate for adaptation for this purpose. To reach this conclusion, a logistical model was made, which was used as a basis for parametric studies. As input to that studies, a seastate timeseries is generated together with different transshipment methods. Two sets of simulations were used to evaluate the effect of the transshipment method in relation to a range of operational limits, and the effect of the distance on the operation. The resulting pipelayer is fitted with two mailbox type docks in the side, this elongates the vessel and decreases its initial draught. These docks are closed and drained afterwards in order to secure the barge. The main conclusion is that it is possible to redesign the original pipelayer to accommodate the transshipment of pipes offshore.

▼ Nowadays the interest for environmental issues is steadily gaining ground. Inescapably, the shipping industry, is also called to contribute its fair share towards the reduction of air pollution. Harbour tugboats need to comply both with international but also with local exhaust air emission regulations, which are anticipated to become more stringent in the future. Kotug, is interested to proactively explore suitable powering solutions, which can be applied at its Rotortugs’ newbuilding scheme, to comply with upcoming regulations of the intended port of operation. The goal of this thesis is to develop a decision-support tool to facilitate the selection process between alternative prime mover combinations, based on what is needed in terms of operation while considering technical challenges, environmental performance and economic returns. The effect of a variety of promising alternative fuels matched with suitable prime movers was investigated for the period 2018-2033, which was set as the study’s time horizon. LNG, Methanol, Biodiesel and DME were assessed as feasible solutions. The first two were associated with gas-burning engines, whereas the rest were associated with conventional 4-stroke compression ignition engines, similar to the ones already installed in the existing Rotortugs running on MGO. The environmental performance differs substantially to a conventional prime mover running on MGO. However, to adhere to future stricter regulations in certain sea areas, additional after-treatment systems are necessary. Research indicated three post-treatment solutions are the most effective in limiting the majority of the combustion-related emissions; Selective catalytic reduction, diesel particulate filter and oxidation catalysts. The total environmental fingerprint of a vessel can be however assessed only under the context of its propulsion configuration layout. The operational profile of a tugboat is highly variable, allowing room for the exploitation of different drivetrains than the traditional diesel-direct layout, which could lead in benefits mainly in terms of fuel efficiency and maintenance savings. Three drivetrains were selected; a diesel-electric and two hybrid, based on AC and DC topology. Before deciding to invest on a future boat a ship-owner is expected to be eager to comprehend the cost-related issues between alternatives. Moreover, the already proven design of the diesel-direct Rotortug, complemented by the necessary after-treatment technologies, makes sense to be the first option to consider, provided it complies with the anticipated regulations. This option is considered the baseline case. It is reasonable to compare all other options against the baseline case. To this end, a decision framework based on a techno-economic evaluation is proposed for supporting ship-owners to take informative decisions on investment considerations; Three objectives were set; economic performance, environmental performance and cost-effectiveness. To quantify economic performance a comparative TCO analysis was implemented,… Advisors/Committee Members: Frouws, Koos (mentor), van Hassel, Edwin (graduation committee), Hopman, Hans (graduation committee), Atasoy, Bilge (graduation committee), Delft University of Technology (degree granting institution).

In the super-yacht industry, value is added by customisation of design. From an engineering perspective, standardisation contributes to working more efficiently and effectively and thus less costly. The perspective of naval architecture company C-Job is that standardisation can contribute to engineering lead time reduction. Since customisation (adding value) and standardisation (reducing costs) are counterparts, a conflict arises when both are aimed for. This thesis proposes a strategy to implement design reuse principles to answer the main research question: How can reuse of design of the non-owner spaces on super-yachts, support reduction of engineering lead time? To provide a substantiated answer to this question three topics are studied. These topics are the design process within C-Job, principles of design reuse and commonalities within existing super-yacht designs. The results of studying the three pillars of this thesis substantiate the proposed solution called the Scale-To-Order strategy. Analysing the design process at C-Job shows that a great portion is consumed by iterating the design to solve all space claim clashes and grid mismatches. Omitting space claim clashes and grid mismatches in an early stage of design would therefore eliminate a significant part of the design process. Reviewing literature on design reuse leads to suggesting the underlying principles of design standardisation, modular design and parametric design for application in the S-T-O strategy. The proposal of using these three principles is based on the commonalities that are found in existing yacht designs. The resulting strategy consists of three stages that follow the kick-off meeting with the future yacht owner. In stage one, principle solutions are chosen, based on the greatest commonalities in existing yachts, that include a typical arrangement below the main deck and a corresponding structural global model and HVAC and sewage principles and routing. In stage two, modifications to the solution chosen in stage one are made if desired. Anticipated modifications can be made modular on beforehand and new modifications can be introduced as modular in the future. Stage three is the scaling of the global model to the desired dimensions and serves as a compliance check for integrity of the model. The goal of the S-T-O strategy is to accommodate engineering lead time reduction in the design phase of super-yachts at C-Job. The expected amount of time saved by employing the strategy is roughly fifty percent of the original concept and basic design phases.

▼ Traceability in complex ship design involves keeping track of the evolving relations between need, requirements and design. Such traceability is not fully developed in the current design process at DMO due to divisions in the design process and between design tools. This thesis proposes to use a single information model to facilitate traceability by connecting the need, requirements and design in a single database. Besides enabling traceability, such an information model can also be used to support modern modelling design tools. In the early design stage of naval vessels – the preliminary design phase – the capability, technical feasibility and affordability of a new ship are defined. Interactions between these three aspects are opaque and rely on the need for a new naval vessel and supporting requirements and preliminary design(s). Determining the need, requirements and design is in this thesis considered to be a ‘wicked problem’. In such problems, information gained by developing solutions helps define the problem itself. However, these solutions can only be determined with a certain interpretation of the initial problem. This results in many (evolving) interactions between the need, requirements and design in the ship design process as one is needed to define the other. With the help of Systems Engineering and Requirements Engineering information and relations in a ship design process can be determined and structured. These engineering fields are widely applied, and current technology enabled the development of computer aided approaches incorporating design theory, including computer aided traceability. One of the current developments in design approaches is the introduction of model-based approaches, which creates the possibility to actively manage more relations and interactions in the design process. Model based approaches such as the Design Structure Matrix are used to visualise relations between information, and Axiomatic Design enables the decomposition and creation of complex relations. A different approach to modelling in design processes is the use of Knowledge Based Engineering. Knowledge Based Engineering field aims to capture not only the relations and interactions between information in design processes, but also ‘knowledge’ about the ‘how’ and ‘why’ in these processes. Each of these model-based developments relies on, or enables, traceability of information. However, having a program capable of supporting an information storage to support these approaches remains difficult to achieve. For this purpose, Shipbuilder software was created to support transparent storage and management of information. In this thesis, theories for modelling approaches, Systems and Requirements Engineering and the DMO design process have been combined. This resulted in one information structure, applied in the Shipbuilder application, which enables traceability. To show that the proposed information model can model a ship and supports traceability, a case study has been performed.

▼ This thesis research is conducted on behalf of the Delft University of Technology and Bureau Veritas Rotterdam BV, and the goal is to improve ship evacuation by analyzing this aspect early on in the design process. First, this summary will provide a background on the difficulties involved with the ship evacuation process . Next, an explanation is given why this thesis proposes a different model. And lastly, how this model is validated is elaborated upon. A ship evacuation is a highly complex process and it is one of the most important aspects concerning the safety of crew and passengers on-board. This process is affected by various factors, largely by the general arrangement. The layout of a ship varies throughout the design period but the most design freedom occurs during the early stage. An estimated 90% of the decisions which have major impact on final design have been made in this stage. As a result, this stage holds the most potential to improve the ship evacuation performance. This stage is characterized by a lack of detailed layout information available, which results in reduced accuracy in evacuation prediction. As of 1st of July 2020 all passenger ships with more than 36 passengers have to perform an evacuation analysis based on guidelines created by the International Maritime Organization (IMO). The guidelines describe two methods, a simplified method for the early design stage, and an advanced method for the detailed or final design stage. The simplified method translates the ship design to a hydraulic network which in turn results in various method limitations. The goal of an evacuation analysis is, among other things, to provide the designer with information about possible congestion points, identify areas of counter- and cross flows, prove that the escape arrangements are sufficiently flexible, and prove that the evacuation time does not exceed a threshold. Evacuation models capable of performing an evacuation analysis tend to have four general components that define the various aspects influencing the process. The four components are configuration, environmental, procedural, and behavior component. Including evacuee behavior in an evacuation model tends to be difficult due to the complexity and lack of research available. Evacuation models can be categorized using various descriptors however resolution tends to dominate. High resolution models are called macroscopic models whereas low resolution models are called microscopic models. Microscopic models simulate each individual evacuee as an agent with certain attributes, such as walking speed and destination. Most early stage evacuation analysis are macroscopic models and simulate the population as a whole. A different macroscopic approach is proposed by Kana and Singer, which uses probability theory to incorporate the stochastic nature of an evacuation process. This method consists of a Markov-Decision-Process (MDP) to calculate the most probable evacuation routes. Policies are determined for each small geometric area, called a state,… Advisors/Committee Members: Kana, Austin (mentor), Hopman, Hans (mentor), Daniels, Nick (mentor), Akkerman, Ido (mentor), Delft University of Technology (degree granting institution).

Offshore wind turbines are designed to persist harsh environmental conditions, including corrosion. Pitting corrosion is one of the most dangerous forms of corrosion. In combination with a fatigue loading, a corrosion pit could result into the failure of a structure, due to a minimal weight reduction. Of the corrosion fatigue process, the transition of a corrosion pit to a fatigue crack is one of the less understood topics. In this thesis, a combined analytical/numerical model is presented that implements mechanisms of both the fatigue, and the corrosion process to determine the moment in time and location in the corrosion pit of the pit-to-crack transition. The hypothesis used to build the model, is that the pit-to-crack transition occurs at the moment that a fatigue crack initiates. Assumptions are made to be able to predict the level of stress and strain at the surface and below the surface of a corrosion pit using a FEM model. Using the stress and strain levels, damage is accumulated until the failure criterion is reached, i.e. when a fatigue crack will initiate. In this research study, elliptical pit shapes are considered, with and without a certain roughness at the surface of the corrosion pit. From the results it is found that a more sharp shaped corrosion pit is a more favourable location for fatigue crack initiation, than a more blunt shaped corrosion pit. The number of cycles to fatigue crack initiation resulting from the developed model are higher, than the number of cycles to failure found by the DNV GL B1 SN-curve for free corrosion conditions. Also, the DNV GL SN-curve is more steep, than a fitted curve through the data points resulting from the developed model. Through a sensitivity study and by considering the number of assumptions and simplifications made in this research study, it is concluded that the spread and uncertainty of the outcome of the developed model is too large to be able to draw conclusions based on the comparison between the results and the DNV GL SN-curves. More research on the input parameters of the developed model will give more certainty and a better validity to the model. It is found that the effect of surface roughness to the fatigue crack initiation life is not substantial, because it affects the stress and strain levels only up to a relatively small depth. The location of fatigue crack initiation is in the pit bottom for blunt shaped corrosion pits, and in the pit wall for sharp shaped corrosion pits. For circular shaped corrosion pits, the difference between the fatigue crack initiation life at the pit wall and the pit bottom is negligible. It is concluded that the model gives a comprehensive basis for the prediction of the pit-to-crack transition, but more (experimental) research on the input parameters will be necessary to be able to give a substantiated estimate of structural life of offshore wind turbine foundations.
