Willems, Jasper (author)As a big contributor to the the global emissions, the maritime sector strives to bring down its greenhouse gasses and hazardous emissions by enforcing increasing strict rules on the exhaust gasses. This gives major challenges to the maritime sector to develop greener modes of transportation. This report investigates the in-cylinder starting...master thesis 2023

Sopar, Luca (author)With the increasing concerns of the emission of greenhouse gases and other pollutants and the push towards sustainable and greener means of transportation, there is a need for new drive systems running on alternative fuels. One fuel that holds significant potential as a marine fuel for the future is methanol. When produced utilising carbon...master thesis 2023

Belmer, Rebecca (author)Introduction - Hydrofoils are often used for high-performance craft. They enable the hull to rise out of the water and reduce drag. A recurring problem is ventilation, this is the presence of a cavity filled with ambient air on the lifting surface. Ventilation causes the lift of the hydrofoil to decrease drastically. A lot of research has been...master thesis 2023

Pothaar, Maarten (author)Progressing targets on GHG emission reduction urge the the Netherlands Ministry of Defense (NL MoD) to reduce the use of fossil fuels, as they announced to contribute to the Paris agreement by reducing its dependency on fossil fuels by at least 70% by the year 2050. However, without sacrificing striking power, because future naval combatants...master thesis 2022

Zuidgeest, Sven (author)The current global fleet is still dependent on conventional fuels as energy source to transport goods to various places in the world. These conventional fuels, such as MGO or HFO, emit large amounts of greenhouse gasses and other pollutant emissions. Regulation concerning these emissions becomes stricter every day, therefore institutions and...master thesis 2022

van Tongeren, Lindert (author)With the introduction of the Energy Efficiency Design Index, concerns have been raised to the survivability of ships with small engine power to maintain manoeuvring capabilities in adverse weather conditions. Therefore, Sui (2021) developed a simulation model from ‘tank to wake’ of a manoeuvring ship in irregular waves to advice a minimum power...master thesis 2022

Iakovou, Iakovos (author)New vessels need to remain fuel flexible in order to handle the uncertainties of the future regarding the available alternative fuels aiming to lower their environmental impact. On the other hand, it is even more challenging for existing vessels that are not fuel flexible to successfully improve their carbon impact. The current study examines...master thesis 2022

van Gelder, Hidde (author)To facilitate the installation of larger monopiles multiple players in the offshore wind market are investigating the floating transport of monopiles to installation locations. This brings the challenge that when these floating monopiles are to be installed by heavy lift vessels, they must safely be handed over to the installation vessel and...master thesis 2022

de van der Schueren, Tom (author)The design space of power plants of naval surface vessels is ever expanding. As a result, the design space has become too large for a human design team to fully explore. Therefore, a concept exploration tool is introduced to generate and evaluate all possible concepts within the design space. An optimal solution is chosen based on ship...master thesis 2022

Ferschtman, Josef (author)In the modern world, environmental concerns arise due to an increase in the green house gas (GHG) emissions of the shipping industry; in 2015, 2,5% of global GHG emissions came from the shipping industry alone. Measures must be set in place to reduce the future emissions. One way to reduce emissions is by imposing the Energy Efficiency Design...master thesis 2022

Scheffers, Evelien (author)Distribution system robustness estimation is crucial in performing a substantiated trade-off in early-stage ship design. To improve the current robustness estimation, a maritime robustness approach (de Vos, 2018) is compared to and verified by a general network robustness approach (Van Mieghem, 2010). The first studied approach is verified by...master thesis 2021

Boxma, Timo (author)As the shipping industry needs to become greener, it has to move away from fossil fuels. For deep-sea shipping, ammonia is marked as a high potential fuel. The AmmoniaDrive concept feeds the anode-off gas from a Solid Oxide Fuel Cell (SOFC) and additional ammonia into an Internal Combustion Engine (ICE). The exhaust gas coming from the ICE can...master thesis 2021

Sharoubim, Sarah (author)Often, vessels have multiple operation modes that are specialised for a certain task. If a vessel is employed with a controllable pitch propeller(CPP), the blade pitch can be adjusted, adding a degree of freedom to the system. This advantage creates the possibility to increase the diversity of operation modes of the vessel and allows for...master thesis 2021

van Duijn, Joël (author)The goal of this thesis is to characterise diesel-ammonia combustion using a mean value first principle approach, and to implement this characterisation of diesel-ammonia combustion in a time domain two-stroke engine model. This model will be used to indicate the technical feasibility of diesel-ammonia as a marine fuel. The main research...master thesis 2021

Gartner, Niels (author)Submarines face an ongoing (technical) battle to improve the operational effectiveness by increasing the submerged endurance and range. Installing lithium-ion batteries on new or refitted diesel-electric submarines has become increasingly interesting based on their relatively high energy density and specific energy. The characteristics compared...master thesis 2021

Pik, Harmen (author)This paper examines a case study to determine the effects on system performance of the power plant and ship operational capabilities, this case is a ship designed by the company DEKC. It is a small general cargo vessel of 2999 GrT (Gross Tonnage) called the Future Trader. The ship design is finished and the ship will be equipped with a modular...master thesis 2021

Kortenhorst, Julia (author)Traditionally, ships are powered by fossil fuels in combustion engines, causing 3% of global greenhouse gas emissions. Alternative installations have yet to prove their reliability and are currently not as cheap or technological ready. <br/>To enable ship-owners to prepare their ship for the future, but postpone their decision on which...master thesis 2020

Zheng, Xiao Sen (author)Ammonia can become an attractive alternative fuel source on-board of ships, since it does not produce SOx and carbon related emissions (including CO2, CO and soot). However, pure ammonia combustion is too slow to drive an internal combustion engine (ICE), a promoter fuel such as hydrogen is needed to speed up the combustion process. Since the...master thesis 2020

Boekhout, Martijn (author)The shipping industry has a notable share in global greenhouse gas emissions and other pollutants such as sulphur and nitrogen oxides. Fuel cells and batteries are identified as relatively new technologies for shipping with high potential and hydrogen is also considered as one of the most promising sustainable fuels, especially for smaller...master thesis 2020

Valk, Jasper (author)Technical developments of the last decades have led to an increase in design space for non-nuclear submarines, especially regarding the increasing amount of feasible power plant configurations. To be able to select the most suitable power plant configuration, it is important to know the effect on the complete submarine design and all systems on...master thesis 2020
