The growth of the cruise industry throughout recent years and the changing public opinion on cruise ships has led to increasing concerns regarding the impact cruise vessels have on the world’s climate and environ- ment. Cruise passengers prefer not to be related with heavy polluting vessels. In fact, trends like responsible tourism and...

One of the most important reasons to investigating fuel cells is the increased level of regulation regarding emissions in the maritime sector, while fuel cells offer the opportunity to reduce these emissions. It was not clear what the impact of these systems would be on a yacht, the aim of this project is therefore to gain more insight into...

The innovation of underwater exhaust systems on ships increases onboard space, reduces noise emission and allows for zero direct emissions. For defense vessels, stealth is increased as the heat signature reduces due to underwater exhaust. However, there is a disadvantage of dynamic back pressure at the exhaust outlet which deteriorates the...

Rising carbon emissions and the International Maritime Organisation (IMO) have put immense pressure on ship owners to make ships more efficient. One way to make ships more efficient is to install an energy saving device (ESD). ESDs are designed to perform at vessel’s design speed and design draft. Thus, there is abundant information available on...

The interest in alternative fuels in the maritime sector is growing due to increasing concerns of the effect of harmful emissions. Hydrogen in combination with a fuel cell has a high potential to be a more environmental friendly solution than the commonly used fossil fuel systems. However, the use of hydrogen encounters problems looking at the...

Waterborn transport currently runs on diesel driven Internal Combustion Engines<br/>(ICE). To reduce Green House Gas (GHG) emissions an option is to shift towards<br/>alternative fuels, like alcohols. This thesis focusses on methanol in ICEs. The<br/>combustion of methanol in ICEs can be done in numerous manners, where fuel<br/>altering,...

Emission regulations applied to marine industry for amongst others the propulsion system of a vessel are becoming stricter due to governmental <br/>agreements to lower the greenhouse gas emissions. Engine manufactures<br/>are enhancing their engine designs to reduce the engine fuel consumption, which is commonly done by implementing a...

The laws and regulations regarding the radiated noise and the on-board noise of the ship are expected to be stricter in the future. There is a big concern in this field, especially for the underwater noise. The radiated noise from the ship is harming the life of the underwater mammals while the on-board noise is threatening the health of the on...

Environmental regulations are continuously raising the bar towards more advanced diesel engine designs ca- pable of minimizing the emissions of polluting substances. The recent IMO Tier III legislation, entered into force in 2016, is forcing the engine manufacturers to meet a NOx reduction of more than 70% from Tier II for all the ships sailing...

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...

Carbon dioxide emission into the earth’s atmosphere by maritime activities are a concern for the people within and outside the industry. This is because of the environmental impacts that are caused by these greenhouse gas emissions which changes the very chemistry of this planet. These impacts can be mitigated by reducing the CO2 emissions which...

The aging behaviour of lithium-ion batteries is studied to develop an aging prediction model for the capacity loss of batteries in full electric ships. This model is used to investigate the effects of battery aging on the battery size and operational strategies of two case studies, a full electric ferry and a full electric tug.

In this graduation thesis the feasibility of a camera as sensor for nautical operations is investigated. In<br/>aerospace and automotive industries autonomous vehicles are already widely tested and used. However<br/>the marine industry has fallen behind in this development. Therefore this research is focussing on<br/>automation in the maritime...

The rapid rate in technological advancements leaves little to none options for our environment to react. The excessive use of "conventional" energy is bringing planet Earth to its knees. However, people started recognizing the value of renewable energy sources.<br/>One of the major renewable sources is the wind energy. The wind energy can be...

The diesel engine plays a dominant role in the field of (maritime) transportation and is expected to do so in the coming years. Depletion of fossil fuels and environmental impact are relevant concerns, widely acknowledged by the international community. NOx contributes to acid deposition and eutrophication. Regulations on NOx emissions become...
