In recent years, ships are expected to improve energy efficiency and reduce carbon emissions. For naval vessels, it is important to be able to maintain their mission profile. It is therefore required to provide real-time advice to the ship’s crew on the optimal speed and propulsion mode settings that include the actual environmental conditions....

With the use of simulation models, predicting and optimising the correct dynamic behaviour and parameters of a propulsion system of a ship can be performed cheap and safe. However, capturing the right dynamic behaviour is very difficult. Besides, building simulation models and determining the correct parameters is a time consuming process. With...

Ventilation events are the result of masses of air being transported from the water surface along the hull, through the propeller plane. Previous research in literature has shown that ventilation induces large and sudden variations of the load on the propeller. The response of the propulsion system had not been documented before. This is a...

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...

During the energy transition, a wind-assisted ship propulsion system has the potential for increasing energy efficiency according to the ship’s EEDI (Energy Efficiency Design Index) in the short term. However, it would not only make the diesel engine run in off-design condition, but its dynamic behavior due to time-varying wind and waves is...

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...

The global warming led to the development of the IMO strategy to reduce the emission of greenhouse gasses for international shipping. The increasing environmental regulation from both international and local governing bodies will ensure to limit accessibility to operational areas with current power plant configurations. These restrictions also...

Dynamic model parameters (e.g. governor) are uncertain and hard to validate. A possible solution can be the usage of parameter identification techniques. So far parameter identification techniques have proved their potential in identifying model parameters on model scale, but this has never been applied on a full-scale propulsion system. During...

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...

Accurately predicting the ship motions, is essential knowledge when operating in water. To predict the ship motions, multiple ship characteristics have to be known. For the roll motion, one of these characteristics is the roll damping coefficient. Nowadays the industry standard to determine the roll damping coefficient of a ship is by performing...

During dynamic positioning operations, vessels typically run with an extra generator (spinning reserve) for redundancy purposes such that no single fault will cause the vessel to lose its position or heading. As a result, all other engines on the grid share the load equally to ensure that if a failure were to occur, the remaining healthy...

The ship propulsion system model is simulated by MATLAB/Simulink initially and is required to reproduce the simulation results in python. This master graduation project deals with the reproducibility of ship propulsion system model by different computer simulation tools. The MATLAB/Simulink model will be provided by Maritime Technology (MT)...

After years of using fossil fuel, the transition to renewable energy sources need to be made to limit the increase in temperature and to support the future energy demand. To support and speed up the transition phase from fossil fuels to renewables it is necessary to decrease the costs. Offshore Wind Turbines are widely used for the production of...

The need for advanced ship propulsion control systems is constantly increasing as the demand for high vessel performance is growing at the same time. Speed trials are considered as an operation during which the vessel has to achieve the highest performance by attaining the agreed maximum ship speed. However, sometimes vessels have to sail in...

The formation of NOx in diesel engines is heavily influenced by the amount of available oxygen and the combustion temperature. This thesis investigates the effects of the implementation of exhaust gas recirculation on the NOx emissions of a 4-stroke marine diesel engine. With EGR implemented a part of the fresh intake air is replaced by exhaust...

In the GasDrive project, a solid oxide fuel cell and a reciprocating gas engine are used to provide electrical and mechanical power for a ship. One of the goals of the GasDrive project is to broaden the limits between knock and misfire for the gas engine. Extending the operating limit could be achieved by addition of anode-off gas. Before anode...

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...

Vessels are becoming more and more optimized towards their mission and an increasing amount of systems are considered during this optimization. Most of these considerations occur at an early design stage, where data is scarce and their impact is large. <br/>This research aims to aid designers in considering this growing forest of possible system...

The time a naval combatant can be deployed for a mission is limited by its dependency on supplies. At a certain point the ship needs to leave the area of operations to be replenished in a harbour or by a support ship. Moreover, the Royal Netherlands Navy has a societal obligation to reduce its environmental impact, in particular on global...
