For many years, ’het Loodswezen’ has relied on its tenders to transfer pilots to and from cargo vessels, with the primary focus on ensuring safety of both crew and pilots. In response to evolving emissions regulations and industry developments, the organisation launched the ’Tend ...
This thesis investigates the yaw stability of wind-driven vessels using wingsails, addressing the urgent need for decarbonising global shipping. An analytical method is developed to assess directional stability based on aerodynamic and hydrodynamic characteristics, yielding a uni ...
A significant push toward sustainability has emphasized the need to make all vessels as energy efficient as possible. Close attention must be paid to the performance evaluation of the vessel’s main energy consumer, particularly the engine. Moreover, prioritizing the efficient ope ...
With fuel cells making their way into the maritime sector, cooling systems are becoming a more important aspect of ship design with regard to power saving. Because fuel cells generate heat at a lower temperature, they require a cooling system that is comparatively larger tha ...

Modularity to Support the Design of a Super Yacht

The implementation of a modular method in the early stage design process of a custom luxury yacht.

This thesis investigates the implementation of modularity in the early-stage design process of custom luxury yachts, specifically targeting the Feadship fleet between 75 and 110 meters. The research aims to determine whether modular design methods can optimize efficiency and crea ...
The study seeks to reduce emissions in the shipping industry by exploring a propulsion system based on hydrogen internal combustion engines (H2ICEs) and liquid organic hydrogen carrier (LOHC) technology. While both technologies are strong contenders for future propulsion systems, ...

Assessing the technical and economic viability of implementing a fuel cell-battery system in a cable-laying vessel

The impact of adding a methanol-fuelled SOFC and batteries to the power plant of the NEXUS on the emissions, design and performance of the ship

This master's thesis addresses the urgent need to reduce the marine industry's environmental impact. Van Oord, a marine player, aims to achieve carbon neutrality by 2050. The study investigates integrating methanol-fueled Solid Oxide Fuel Cells and batteries into the cable layin ...
This paper provides an initial feasibility study of the potential installation of iron powder energy generation systems aboard a marine service vessel. After a short introduction as to the relevance of this study, the state-of-the-art iron powder energy generation is investigated ...
In response to the leading narrative of increasing sustainability in the yachting sector, a research collaboration is started between the Delft University of Technology and Dykstra Naval Architects to examine the potential use of hydro generation on board sailing superyachts. By ...
This master’s thesis explores an alternative approach to enhance the emission performance and energy efficiency of offshore installation vessels without expensive retrofits. The concept involves employing swappable energy containers, currently used for inland cargo and tug vessel ...

Transshipment for the 21st Century

A Novel Approach to Deep Sea-Hinterland Transportation

Transshipment is a key component of modern-day shipping logistics. Container supply chains rely on transhipment hubs to access remote locations. With globalisation driving growth in container trade, maritime congestion is rising at container terminals in ports worldwide. This is ...
To reduce the climate change impact of shipping and retain compliance with increasingly strict emission regulations, alternative fuels are required. Methanol is expected to be one of the renewable alternatives. However, it evaporates easily compared to for example Diesel and its ...

The Plug-in Hybrid Electric Superyacht

An operational data-driven design

This study aims to provide a proof of concept of a plug-in hybrid electric superyacht. In this way, the yachting industry can help reduce carbon emissions worldwide and potentially increase comfort levels. The concept takes advantage of the typical operating profile of a yacht. A ...
Stimulated by the energy efficiency indices introduced by the International Maritime Organization, the increased attention for the environment as well as economical pressures emphasize the relevance of accurate resistance estimation for ships. This leads to a particular interest ...
The adverse human contribution to global climate change has forced the yachting industry to acknowledge the need to reduce its environmental impact due to the client's increasing pressure and potential future regulations to limit the ecological effects. Unfortunately, current rea ...

A methanol impact tool for yachts

Assessing the impact of using methanol as an alternative fuel on the design, emissions and costs of yachts

Superyachts are large emitters of greenhouse gases, as well as other emissions such as NOx, SOx and PM. In order to meet the climate goals set by the IMO, to reduce GHG emissions by 50% in 2050, alternative fuels are being investigated. Methanol is an altern ...
In order to meet climate change mitigation targets, the shipping industry must change to an alternative fuel. From a ship design perspective, the switch to an alternative fuel is often a downgrade with respect to the use of conventional fuels. For instance, most alternative fuels ...
Ammonia (NH3) may reduce CO2 emissions from the marine industry as it is carbon-free and more energy-dense than hydrogen or batteries. Pure ammonia exhibits poor combustion characteristics, so several researchers have already operated small-scale internal combustion engines (ICEs ...
