1. de Bruijn, Lukas (author). Maintenance dredging in the Port of Rotterdam: A research to the increase in maintenance dredging volume at Port of Rotterdam.

Degree: 2018, Delft University of Technology

The Port of Rotterdam (PoR), located in the Rhine-Meuse estuary, is subject to sedimentation. In order to keep the port accessible for vessels with high drafts, maintenance dredging works are done. The maintenance dredging over the port area is executed by two parties, PoR itself regarding the harbour basins and Rijkswaterstaat (RWS) regarding the river and waterways. Since 2013 a substantial increase of the yearly total maintenance dredging volume of the area under control of PoR is observed. The problem of this research is the increase in maintenance dredging volume, from an average of 5.2 mln cubic meters a year (over 2005-2012) to an average of 8.9 mln cubic meters a year (over 2013-2016). By analysis of the administrated maintenance dredging volumes database of PoR it is concluded that the problem is concentrated at Maasvlakte I. Including the maintenance dredging volumes data of RWS results in the conclusion that over the entire port area no occurrence of an increase in maintenance dredging volume is observed. A decrease administrated by RWS at the same period of time is concentrated at the area in front of Maasvlakte I, the harbour basin responsible for the increase in maintenance dredging volume of PoR. These findings lead to the conclusion that not an increase of sedimentation over the port area is responsible for the research problem, but a redistribution of the sedimentation rates from the area in front of Maasvlakte I to Maasvlakte I is. An analysis of the events that are potentially of influence on the research problem is performed. Based on the correlation of time and potential impact on the hydrodynamics of the water system, the event 'Construction of Maasvlakte II' is selected for an assessment. Two simulations with an extensive hydrodynamic flow model managed by PoR are run. One simulation includes the layout of the Maasvlakte before the construction of Maasvlakte II, the other includes the layout of the Maasvlakte as it is today. Both simulation use exactly the same initial and boundary conditions. With use of the simulations, the impact on the hydrodynamic conditions within the area of interest is assessed. The results show a significant increase of the tidal filling volume of the Maasvlakte harbour basins with a factor of 1.4. This increase is associated with in particular a significant increase of the horizontal flow velocities, and strengthened by a higher horizontal density gradient as a result of higher mixing rates of fresh and saline water at the Maasvlakte. The increase of the horizontal flow velocity is in particular measured in front of Maasvlakte I and in the connection to Maasvlakte I itself. Within the Maasvlakte harbour basin, the velocities are quickly dampened by the large width of the basin. The results of the assessment correspond accurately with the results of the data analysis. At the area subject to an increase of the horizontal flow velocity, a decrease of the maintenance dredging volume is observed. At the area where an increase in maintenance… Advisors/Committee Members: Vellinga, Tiedo (mentor), van Maren, Bas (mentor), Wijdeven, Bas (mentor), Kant, G.

2. Koster, Piebe (author). Concept level container terminal design: Investigating the consequences of accelerating the concept design phase by modelling the automatable tasks.

Degree: 2019, Delft University of Technology

The design of a container terminal is a process that goes through a number of phases. One of the first is the concept design phase, which is needed to make a first assessment of the project's technical and financial feasibility. This phase is exploratory of nature, because of the early stage in the design cycle and consists of several tasks that often dependent on certain design choices. One of the most influential choices in the early stages of the design cycle is the stack equipment choice. It has a significant influence on the two primary deliverables of a concept design: the land use and the cost estimate. The problem definition holds that in practice, there is often only limited time available for the concept design phase. The short duration of the process affects the design effort by engineers in two ways. First, not all possible stack equipment options can be considered in detail, which generally is solved by an expert judgement based design freeze early in the process. And secondly, not all designs that are considered are visualised, as often only the preferred design option is visualised at the end of the process. A quick visualisation would help to better understand the design itself, and the interaction with its environment. An important consequence of the above work method is that not all potential solutions are being assessed throughout the design process. This limits the adaptability of the design process and can potentially lead to suitable solutions being overlooked. To improve the design process, more stack equipment types should be considered and evaluated throughout the process, and all considered design options should be visualised. This is as yet not possible in the limited time available time in the concept phase with the currently available tools. This problem leads to the following research question: What are the consequences of accelerating the generation and visualisation of concept level terminal designs, by modelling the automatable tasks, on the concept design phase? A typical concept design process, as defined in this report, consists of six stages and has an indicative duration of four to eight weeks, depending on the exact outline of the project and the local conditions. The tasks that correspond to the generation of the various terminal concept design options (i.e., concept level calculations, layout generation, cost estimation and visualisation) are considered to be automatable. An examination of currently existing design tools demonstrated that there is currently no available tool that meets the requirements and therefore, a specific design tool must be developed. Parametric engineering is the chosen method for automating the concept level design process as it allows for different solutions to be explored and provides for flexibility during the process. Based on both expert interviews and studied literature, it has been decided to build the design tool using a combination of two packages in which Python is used for concept level terminal… Advisors/Committee Members: van Koningsveld, Mark (mentor), Wijdeven, Bas (mentor), Krom, Jan Kees (mentor), van der Linden, Lennert (mentor), Delft University of Technology (degree granting institution).
