This research was performed with the goal of giving insight if the Rijksrederij is able to operate part of their fleet on renewable methanol and fuel cells, in order to work towards their goal of operating with net zero CO2 emissions by 2030. This prompted a research question that focussed on both the renewable methanol supply and the technical...

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...

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...

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...

The use of fossil fuels and their impact on humans and nature is becoming a bigger concern worldwide. An interesting concept to lower polluting emissions coming from maritime engines is the combined use of a dual-fuel engine and an underwater exhaust system. In the dual-fuel engine natural gas is used as the main fuel type. It is seen as a...

The reduction of the of harmful emissions that result fromyachting are an increasing concern and priority. It has been widely established that yachts have a significant contribution to the emission of greenhouse gasses and other emissions that are harmful to the environment and the public health. Measures must be taken that drastically reduce...

In the volatile and demanding current market and in view of frequent implementation of new emission regulations, ship renovations entail more and more radical conversions of higher complexity. Application of optimization methods in the ship maintenance, repair, and conversion industry have been so far frequently overlooked, due to the former...

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...

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...

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...

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...

In this study, various scenarios were developed that correspond to estimations of future biomass availability and biofuel demand from the maritime industry. These marine biofuel demand scenarios were based on the Greenhouse Gas (GHG) reduction targets of the Renewable Energy Directive II (RED II) and the International Maritime Organization (IMO)...

The Royal Netherlands Navy (RNLN) seeks to eliminate net green house gasses and other harmful- emissions. In this search, the operability of her vessels need to be secured. One of the options for eliminating net carbon emissions is Power to Liquid (PtL) conversion to Methanol. Fuel cells, and in particular Solid Oxide Fuel Cells (SOFCs) may be...

The awareness of the climate change is increasing and the effect of air-pollution is irrefutable. To decrease the emissions of large ships the required amount of fuel has to be minimized. This is done by increasing the efficiency of the engine, decreasing the hull resistance or by lowering the cruise speed. Another interesting way of decreasing...

For many maritime applications Li-Ion batteries are foreseen as energy storage units that can improve the performance of the on-board power system in terms of continuity of service, fuel consumption, emissions and running hours of main engines. However, one of main limitations of battery application in on-board power systems is the aging of...

To improve the submerged time of diesel-electric submarines (SSK), air independent power (AIP) systems have been developed in the past. So far only submarines with AIP systemsin combination with one or more diesel generator (DG) sets are designed and built. The increased technological readiness level of modern fuel cells (FC) and the energy...

To reduce global warming and air pollution, the maritime industry is searching for solutions to reduce fuel consumption. This thesis focuses on the reduction of generator running hours and fuel consumption of Dynamically Positioned (DP) vessels. In this ship type, redundancy of the power generation system is regularly achieved by running on one...

Keeping a submarine stable underwater is important to be able to execute missions. Therefore, one of the main systems on board of submarines is therefore the ballast trim system. This system is able to maintain the submarine balanced. There must be equilibrium in weight and buoyancy as well as in the trimming moment. This makes the ballast trim...
