▼ 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. So the…

▼ The research effort on autonomous ships has increased over the last years. The realisation of these ships will have as a consequence that the crew can be reduced significantly or even be removed entirely, resulting in unmanned ships. Although there is a strong belief that unmanned ships would lead to more economic efficiency, only limited research has been performed in order to demonstrate what the overall effect of the change to unmanned shipping would have on transport costs. Nonetheless, more reductions in cost or improvement of transport performance for unmanned ships would make them more attractive and economically viable. The design of a ship is subjected to regulations and requirements that limit the design freedom, but it increases safety. Removing the crew from the ship reduces the risk of shipping, under the assumption that the probability that an incident occurs does not change, since the lives of the crew are no longer at risk. If the risk is lower, the requirements to the design of unmanned ships might become less strict, while maintaining equivalent safety. In this way more design freedom can be realised for unmanned ships, as well as more economic efficiency. Within this report the required subdivision index will be evaluated, for it is expected that reducing this requirement can create more design freedom. Therefore, this research will focus on what reduction in the requirement concerning damage stability for unmanned ships can be allowed, if they are subjected to an equivalent level of risk as manned ships of the same size and type. It has been found that the required subdivision index can be lowered for unmanned ships, based on equivalent safety. The contribution of the risk of losing lives to the overall level of risk is larger for smaller ships. This is reasonable, since for larger ships, the size of the crew increases with a lower rate compared to the amount of cargo, installed power or capital costs. Therefore, the allowable reduction in the required subdivision index is largest for smaller ships. However, the size of the reduction depends strongly on missing accident statistics concerning the loss of life. The missing data results in the following uncertainties, for which further research is recommended. Firstly, for different ship types differences in the accident statistics are present. There are significantly less fatalities related to bulk carriers and container ships compared to general cargo ships. It is expected that these differences are related to the individual ship size and crew size, for which both the correlation with the probability of losing life is unknown. Secondly, there is a discrepancy between the theoretical probability of survival of a ship, namely the attained subdivision index, and the probability of survival that the accident data suggests. The attained subdivision index suggests that at least 30% of all accidents should lead to a total ship loss. The accident data reveals that for general cargo ships around 10% leads to a total ship…

▼ This M.Sc. thesis is related to the use of Design Structure Matrix (DSM), a design process modeling technique, to model, analyze and improve design processes in Oil and Gas Construction Projects. DSM was used to model the design process of an engineering design section at an Oil and Gas Engineering Company using the information dependencies in the design process. The key effects of the information dependencies that were studied in this thesis include rework due to iterations, change propagation in the design process and need of design team collaboration. Further, the current design process was improved in terms of design schedule by proposing a new design process with reduced rework risk. Finally, ecommendations have been provided to improve the design process on the three aspects related to information dependencies in design process as mentioned above.

▼ 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.

▼ This thesis is about the identification of an optimal modular platform-based product development design process for a series of support vessels of the Royal Netherlands Navy, viewed from a Damen Schelde Naval Shipbuilding perspective. Because of increasing competition in the global shipbuilding market, the demand for ships with higher quality, lower lifecycle costs and shorter delivery lead time is growing. Advanced manufacturing technologies can partially address these challenges, but advanced design technologies are critical, since most design and manufacturing properties of a ship are influenced by the design decisions that are made in the early design stages. This makes a modular architecture platform approach very suitable. Moreover, it provides multiple opportunities to various stakeholders to benefit from. To clarify, standardisation means the use of identical components across multiple products and modularity means combining standardised components to create modules and/or building blocks. After the evaluation of the literature on modular platforms, an existing modularity method, called Modular Function Deployment (MFD), is expanded by Systems Engineering design disciplines/theories. Hereby, key aspects of platforming and modularisation principles were taken into account. Subsequently, the case study carried out explored whether the composed method is appropriate. In other words, the case study serves as a guideline and indicates which aspects must have close attention, because of encountered complications.

▼ This thesis aims in the development of a parametric modelling method for the preliminary ship design based on Knowledge Based Engineering (KBE). The research work was conducted in cooperation with C-Job Naval Architects. Nowadays, parametric models can be seen as the core of the design practice since they facilitate the exploration of the preliminary design space, and thus, multiple design solutions can be assessed. The present work proposes a parametric modelling method based on knowledge building blocks instead of geometric entities, and thus, KBE was identified as a suitable tool to deploy for its development. The starting point of the design method is the identification of the design requirements and the main drivers analysis of the vessel type. The next step is associated with the determination of the High Level Primitives (HLPs), which are the building blocks of the design containing product knowledge. The HLPs are qualitatively and mathematically described. Finally, in order to form the vessel’s parametric model, the HLPs are combined and tuned to fit the design problem. The proposed method was applied to the LNG bunkering vessel in a case study. A real design case of the company and three more design cases are described and assessed.

▼ 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.

▼ 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…

▼ 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…

▼ In the packaging industry, there are certain criteria that characterize whether a package is sustainable or not. Thus, the design of the product is decided by satisfying the aforementioned criteria. However, when the whole supply chain is under study, the process is not so straightforward and the related science field is Sustainable Supply Chain Management (SSCM). In this master thesis the effects of the food industry specific supply chain sustainability criteria on the package design will be investigated. With a thorough literature review those criteria are going to be identified, while with interviews data about the current package alternatives of certain products will be collected. With these inputs a Multi Criteria Decision Making (MCDM) problem is formulated and will be solved with the use of the Best-Worst Method (BWM). On the one hand, the BWM achieves the ranking of the supply chain sustainability criteria by estimating their respective weights and on the other hand the selection of the optimal design among the alternatives. The implementation of the analysis took place for three selected products of the Kraft Heinz Company; the Heinz Tomato Ketchup, the Heinz Seriously Good Mayonnaise and the Heinz Beans. The preferences of the supply chain members of these selected products were documented and the optimal package designs were selected. It has to be underlined that equal importance was given to the weights of the six different supply chain members and the three dimensions of sustainability. The dispenser Sauce – O – Mat was selected as optimal for the sauces, while the Can for the beans. It was proved through what-if scenarios that modifying the weights that that decision-maker assigns to the preferences of the supply chain members and the importance of the dimensions of sustainability has an effect on the selection of the optimal design. In the end, a decision-making tool was created that improves the selection process of package alternatives in the food packaging industry.

▼ 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 CO
2 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 CO
2 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 CO
2 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 CO
2 emissions for a certain voyage and assessing the effect of CO
2 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 CO
2 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 CO
2 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 CO
2 reducing measures with the objective of minimizing costs. The output of the tool consists of the expected values of total costs, CO
2 emissions and CO
2 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 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.

▼ Defects that occur on train sets have to be repaired in a repair location and this has consequences on the transportation network. This paper proposes a decision support model that is developed for optimising the decisions of when and where to repair that defect train set. In practice, there is no clear overview of the effects of such decisions on the overall system. This paper first describes the current decision process including the considerations for decision making. Then a mathematical model is developed and tested with multiple scenarios of varying repairing times and Q times. The results show that the proposed decision support model provides significant improvements compared to the current approach and can save even millions of euros. However, more research is required in order to ensure the real-time performance of the methodology.

▼ The design of polar expedition cruise ship is not a trivial task to the naval architect due to the complex nature of the ship itself. Concept exploration are hereby required to improve the understanding of the design problem and identify its challenge as well as possible solutions. However, it is always difficult to generate the technically-feasible design solutions while still satisfying multiple and potentially conflicting performance criteria for the polar expedition cruise ship. There are currently two ways of optimizing the concept design: manual optimization and computer-optimization. The computer-based optimization, such as the Packing Approach developed by TU Delft, can semi-/automatically generate a set of design solutions. After the generation of these design solutions which are unknown in many performance behaviors, it is necessary to post-process them and increase the quality of those designs created from both optimization methods. Design rationale is an effective way to serve as qualitative metrics in post-processing the configuration layouts of the concept designs. However, the ambiguity and potential conflicting aspects within the design rationale are difficult to handle by the current post-processing method while fuzzy logic theory can be utilized to cope with the design problems involving subjective and ambiguity. Hence, it is proposed to develop a new methodology to better post-process the concept design of a polar expedition cruise ship.

▼ Recently the interest in hydrofoil vessels using a fully submerged hydrofoil increased. Hydrofoil vessels experience a resistance hump and possible instabilities during their takeoff of which both are influence by waves. In order to determine the required power during the takeoff to overcome the resistance hump and to investigate whether the hydrofoil vessel is stable during the takeoff numerical simulations or experiments have to be performed. Experiments covering the full takeoff require a long towing tank and high towing velocities and therefore these experiments are costly. The alternative, performing numerical simulations, is favorable but requires a suitable numerical code. As no validated code is available in which a takeoff can be performed in waves, in this research Panship, a potential flow code suitable for high speed craft and adapted for use with hydrofoil craft, is validated for the takeoff of a hydrofoil vessel. In this research the results of Panship are compared with results of experiments and other numerical codes in four different stage as little validation data is present for the takeoff of a hydrofoil vessel. The four different stages are: a foil without the influence of the free surface, a foil with the influence of the free surface, two foils with the influence of the free surface and the hull and foil system near during the takeoff. In these four stages the lift and drag determined in Panship is compared with available experimental results and numerical codes. As the simulations in Panship require a vast amount of input parameters, the influence of these parameters is studied first to ensure the reliability of the results. Comparing the results of Panship for a deeply submerged foil with another potential flow solver shows that the lift is predicted correctly, but that the induced drag is underpredicted. If viscous effects are required in the solution, the quality of the results of Panship is dependent on the type of hydrofoil used. As some foils have a large viscous effect on lift, the lack of viscosity on Panship, leads to a low quality of the results for lift and induced drag as they are overpredicted. The trends for interaction of a foil with the free surface are predicted correctly but the underprediction of induced drag influences the quality of the results. Panship is able to predict the effects of foil interaction for lift correctly, but the results for foil interaction for drag are poorer. During the takeoff Panship is able to predict the lift fairly correct but the total drag is underpredicted severely. Recommendations are given to improve the results of Panship and for future work.

▼ In the early 00 of this century, Keuning et al. (2007) looked into the hydrodynamic forces on the rudder and the influence of the hull and keel on these forces. Among others, they have assessed the lift and drag forces on the rudder. One of the outcomes of this study was an asymmetric lift curve; for negative rudder angles the rudder seems to stall at angles more than five degrees smaller than for the positive rudder angles. The goal for this research is to find and clarify the physical phenomenon which induces the rudder to stall at smaller rudder angles when subjected to a negative rudder angle (during bearing away). The main question to be answered in this report is: What physical phenomenon is at the basis of the asymmetric stalling behaviour on the rudder of a sailing yacht? Towing tank tests are used to validate the data from Keuning et al. (2007). After which RANS CFD simulations are conducted in NUMECA to compare the towing tank tests to and to visualise the wake of the yacht in attempt to clarify the phenomena found. A number of conclusions were found in this study. Firstly, the results of the towing tank experiments showed similarities to the previous experiments by Keuning et al. (2007). Differences are found in stall angles for positive rudder angles. These differences raise questions on the correctness of either of the experiments. Secondly, no reasonable explanation is found for the negative drag forces found in the towing tank experiments. It is expected that these originate from the set-up of the rudder. Thirdly, the lift curve found in the experiments is confirmed by the CFD data for the test cases. The physical effect behind the early stall behaviour of the rudder is still unknown. It is indicated that a part of the decrease in stall angle, a couple of degrees, is caused by the influence of the keel, when the disturbance passes on the low pressure side of the rudder. The hull is responsible for the remaining decrease. The CFD data indicates an influence of the vorticity of the keel and the boundary of the hull to cause a disturbance on the rudder. Further research in necessary to clarify the results found in this study.

▼ 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. A small model of both an S- and…

▼ Rationale - Increasing world population and consumption, and rising dependency on certain countries for the supply of raw materials lead to the demand for new raw material resources. This demand, combined with the increase in complexity of new land-based mining operations increases the chances for a viable offshore mining business case. Goal and scope - The aim of this research is twofold. The first aim is to fill knowledge gaps in the offshore mining value chain, with a focus on the processing of the mined material. The second goal is to assess if shallow water offshore mining is a viable business option. Explicitly left out of scope are the exploration for mineral deposits as well as the detailed or new design of an extraction method for subsea minerals. Furthermore, resources beyond the continental plate are not part of this research. Approach - To answer the first goal of this research, an extensive literature study is performed comprising an assessment of potential offshore mineable minerals and their respective markets. It also included an analysis of current land-based mineral processing techniques and its limitations in an offshore environment. Furthermore environmental, legislative and tax aspects were included as well as detailed descriptions of future offshore mining projects, and current dredge mining projects. To assess the viability of an offshore mining project, a case study is set-up of a prospective offshore mining project. A method for executing the case study is developed. Results of the case study - For the case study the mineral deposit has been studied and based on its mineral characteristics a location specific processing flow sheet is developed. The case study resulted in a set of execution alternatives, from which a preferred option was selected. Based on this option the viability of the project is assessed with the use of a discounted cash flow method (DCF-method). Conclusions - Main knowledge gaps are identified as the impact on the environment, and the lack of legislation regarding offshore mining. Furthermore, it should be noted, that the public opinion regarding offshore mining is important to consider as well.
This project was done in cooperation with Van Oord Dredging and Marine contractors, therefore any company specific information is not taken into account in this public report.

▼ 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,…

▼ To decrease Europe’s harmful emissions, the European Union aims to substantially increase its offshore wind energy capacity. To further develop offshore wind energy, investment in ever-larger construction vessels is necessary. Designing these vessels is difficult however, as this market is characterised by a large but seemingly unpredictable growth of market demand, turbine size and distance from shore. Currently no way of dealing with such market uncertainty within the ship design process was found to exist. This research aims to develop a method that is able to deal with market uncertainty in early ship design by increasing knowledge when design freedom is still high. The method uses uncertainty modelling prior to the requirement definition stage by performing global market research, and during the concept design stage by iteratively co-evolving the vessel design and business case in parallel. The method consists of three parts; simulating an expected market from data, modelling multiple vessel designs, and an uncertainty model that evaluates the performance of the vessels in the market. The case study into offshore wind foundation installation vessels showed that the method can provide valuable insight in the effect of ship design parameters like main dimensions, crane size and ship speed on the performance in an uncertain market. These results were used to create an initial design that is expected to perform well in the uncertain market. The developed method thus provides a way to deal with market uncertainty in the early ship design process.

▼ This research has been performed with the goal to set up a model for the comparison of the environmental impact caused by the production of yachts. This model is created in such a way that it can be implemented in the YETI, Yacht Environmental Transparency Index, which is currently under development. The model that is created is based on a Life Cycle Assessment methodology named Fast Track LCA. This methodology consists of five steps which are further standardized to meet the requirements of the YETI. Choices are made for the functional unit, system boundaries, the quantification of materials, the assessment method, environmental database and LCA software. With a case study, the created model is validated as the results have realistic values. Some other design choices are applied on the case study to check the sensitivity of the model. The sensitivity was enough to show the effect of a different hull material and the use of batteries for the hotel load and peak shaving. It is concluded that the model can be used for the comparison of the environmental impact from production of different yachts. However, it should be noted that due to design choices for the model based on the requirement for comparison, the outcome itself is an underestimation of the environmental impact from yacht production.

▼ There lies an opportunity for significant cost savings in the installation of subsea cables in offshore wind farms which is why the current work proposes a state-of-the-art method for monitoring the cable during installation. The proposed method enables offshore crew to look through the water with the use of augmented reality. To this end a real-time numerical model of the subsea cable dynamics is developed. The model is created in programming language C# and visualization in augmented reality is done using the game-engine Unity. This development environment is uncommon for engineering and scientific purposes and has been selected based on its ability to visualize model results in augmented reality, its extensive graphics library, its capability to process real-time in- and outputs and its free availability. Relevant physics are analyzed on contribution to global cable geometry and tension for the case of shallow water cable laying, resulting in an equation of motion which is sufficiently accurate for representing the physical phenomena occurring during cable lay. An assessment of the measurements required by the model during operation is made. The main challenge of modeling in real-time is that the average model time step is limited by available computational power, in turn limiting the axial stiffness range which can be modeled without the occurrence of numerical instability. Discretization is done using a lumped mass method. It is shown that cable dynamics can be modeled in real-time using an explicit method and that overcoming the associated limitation on axial stiffness does not lead to inaccurate results. The developed numerical solution is verified using OrcaFlex, which is typical software for dynamic analysis of offshore marine systems. An augmented reality interface is developed, including color codes indicating the structural state of the cable. The current work enables the visualization of the real-time model in augmented reality. Potential legal issues related to the implementation of augmented reality during offshore cable lay are outlined during a collaboration with Tilburg
University. Successful practical implementation of the proposed innovation is associated with promising opportunities.

▼ This thesis research focusses on winning at sea. "Winning at sea" requires presence of relevant capability at the right time and for the required time. A winning fleet is a fleet that has the capability to achieve this. The goal of this research is to define a winning fleet and to create a method that can provide insight in how such a fleet can be obtained and maintained. One of the main challenges when operating a naval fleet is to match the fleet capabilities with the capabilities required from the missions that occur over time. The first part of this problem lies in the fact that it is never known what the future will bring. Especially when looking at a period of 30 years which is the general lifetime of a naval vessel. In practice this is partly countered by introducing a major update at the halfway point in the ship's life cycle. The other part of the problem is that the fleet capabilities need to be distributed over the different vessels and vessel types. Because having an infinite fleet size would be far too expensive, certain compromises need to be made. The main of which is that having a finite fleet will result in lower costs but also means that when a vessel is occupied all capabilities of that specific vessel are unavailable for other activities. For this reason it is important that the fleet composition is constructed in such a way that at all times, or at least within an acceptable error, the requirements set by the missions can be met. The method that is created during this research acts like a proof of concept of whether such a method could be useful in the future. This research should be able to help with the iterative process of balancing the operational need and design requirements with the feasibility and affordability that occurs within the early design stages of naval fleet design. The main stakeholders in this process are Commando Zeestrijdkrachten (CZSK), the department of planning (DPLAN), and the Defence Materiel Organisation (DMO). These three parties can respectively be categorized as the user, military planner, and the supplier. In order to reach the research goal a model has been created that simulates naval fleet behaviour. This Fleet Behaviour Model (FBM) describes a fleet as a collection of capabilities which are distributed over different vessel types. In order for this fleet to be operational it needs to comply with certain Life Support Activities (LSA) such as maintenance and the training of the crews. The operational need of this fleet is simulated by generating mission scenarios which require certain capabilities from this fleet for a specific time and at a specific location. Next to requiring mission specific capabilities from the fleet the missions also have the possibility of enemy presence. When this happens naval combat is simulated which introduces attrition into the model. The inclusion of attrition into a fleet behaviour model is what makes this research unique. Using this model the performance of multiple fleets can be tested against one or more scenarios.…

▼ From shallow to deep water, from the well to the ship, from the offshore field to shore or between countries, many kilometres of offshore pipelines for transportation of hydrocarbons (oil and gas) have been installed over the last decades. Allseas’ Tog Mor is a shallow water pipelay barge capable of laying pipes up to a water depth of 25 meters. Currently, Tog Mor is more than forty years old and is due for replacement. Therefore, Allseas has considered to replace Tog Mor with a new shallow water pipelay barge. However, it is unclear whether the current barge is optimised for pipelaying since it is designed for crane supported purposes. The aim of this research is to give insight into vessel properties which determine the pipelaying performances and to define a set of design requirements for the new shallow water pipelay barge, Tog Mor 2.0. To define the requirements of Tog Mor 2.0, the principles of Systems Engineering are followed. Based on the operational analysis, the performances of Tog Mor can be improved by a reduction of the theoretical peak cycle time, optimisations of the pipelaying process and a reduction of downtime. The output of the operational analysis in combination with the principles of pipelaying results in potential bottlenecks. Those performances and potential bottlenecks were the input of the functional definition of Systems Engineering. The aim of this functional definition is to allocate functions to systems and to prioritise the design focus point in terms of functions. Those functions were translated into hardware components and integrated in the total design. Due to the inversely proportional relationship of the number of production days and corresponding production costs, an increased number of stations and lay speed do not have an advantage in terms of costs. In order to reduce the theoretical peak cycle time, the specifications of the functional equipment are improved and the need of buoyancy modules is reduced. Less need of buoyancy modules is achieved by the increased capacity of the tensioner (two tensioners of 100 ton each) and an inner stinger. The pipelaying process is optimised by free deck space, a higher level of redundancy of the functional equipment and new technologies of equipment. The level of redundancy in combination with the improved workability results in a reduction of downtime. Those improvements results in a final concept design which proposes a barge with an off-centre firing-line of five stations (three welding stations, one testing & grit blasting station, one coating station). As a result of an improvement of each individual function and the interactions among those functions, an improvement of 30% in terms of theoretical minimum peak cycle is achieved by an optimisation of the pipelaying process and potential bottlenecks. A reduction of the peak cycle time, an optimised pipelaying process and a reduction of downtime percentages results in an improved overall performance of Tog Mor 2.0 compared to the current Tog Mor.

▼ The current operational cost estimate applied by shipping management companies is insufficiently valid and accurate for determining the operational budget. Most shipping management companies include scheduled maintenance jobs in the operational cost calculation. Scheduled maintenance does not take unforeseen maintenance into account. In retrospect, unforeseen maintenance makes up approximately 8% of the total operational costs. The estimation of the operational costs can be improved by including the unforeseen maintenance costs. Improved operational cost calculations lead to better substantiated maintenance policy decision-making. Therefore, the (unforeseen) maintenance costs over the lifetime of a vessel are modelled. This research focuses on maintenance cost calculations, based on failure behaviour. First, it is explained how the Maintenance Cost Model calculates and compares the costs of different maintenance policies. Thereafter, the model is validated in a case study. The achieved cost reductions resulting from the case study varied from 0% to 70%, with a conservative average of 16%. Next, the case study conclusions are assessed in a sensitivity analysis. The model generates a, system specific, cost based ranking of the maintenance policies. The ranking can be used by shipping management companies, to obtain a better substantiated system specific maintenance policy. The developed model in this research is generally applicable and proves the concept. The research concludes with recommendations for future research, which includes further expansion of the Maintenance Cost Model and the possibilities to increase the likelihood of the number of replacements.

▼ The Defence Materiel Organisation found that using a design margin to estimate required space for logistic systems (e.g. staircases, hallways) during the concept exploration design phase is insufficient and impractical. A more educated estimation of required space for logistic systems is hard, because the configuration of systems is varied significantly. Indeed, the size and location of logistic systems are dependent on the location of functional systems, amongst others, which could be driven by logistic systems in turn. To solve this iterative problem, a novel Logistic Model was created and integrated in the TU
Delft Packing approach. Based on a network representation of the ship's structural subdivision, a novel path finding and selection approach, initial positions of functional systems and upfront defined logistic relations between these functional systems, the size and location of logistic systems has been determined for and integrated in each concept design created by the TU
Delft Packing approach. The logistic performance of the low detail designs was calculated by a novel Logistic Performance Measure and used to find logistically promising designs during concept exploration. Test cases indicated that the new method meets the research objectives.

▼ The subject of this research is the concept design of a compact and economically feasible platform for studying the behaviour of bowhead whales in the ice-infested water around the coast of North-East Greenland and particularly in the Fram Strait. The study is focused on the capabilities of the vessel to operate in a dynamic ice-infested environment and on the strategies to be used for surviving in such a harsh area. An extensive part of the research consists in an environmental study of the ice and climatic conditions of the Fram Strait which are barely available in literature. The design is carried out using a System Engineering approach in order to evaluate the mission and its requirements and to transform them into high-level concepts which are compared through the usage of an Analytic Hierarchy Process. The ice-breaking capabilities are evaluated using the Net Thrust Concept and the ice loads in compressive ice are calculated through a quasi-static approach with ISO19906 standard for Arctic offshore structures. The final concept design proposes a vessel that can accommodate a crew of six people and that can perform the research activity also underwater through a moon pool. The vessel is able to reach the operational location autonomously and to drift following the ice movements towards South. Moreover, it is able to cope with compressive ice events thanks to a rounded hull that lifts the vessel up when compressed by ice. Overall, the construction and operation of the Drifting Ice Vessel are judged to be feasible. However, the task is not without risks and further experiments, tests and trials are recommended, to verify more deeply and validate the ice-loads estimation and the lifting behaviour of the hull.
