Retrofit modeling for green ships: A data-driven design approach for emission reduction using bunker delivery notes

This thesis presents a data-driven design approach for emission reduction using bunker delivery notes (BDNs) to help support the revised IMO strategy to achieve net-zero greenhouse gas emissions by international shipping close to 2050. This research supports the Horizon Europe’s Digital Twin for Green Shipping (DT4GS) project which focuses on...

Operational Impact of Ammonia as Marine Fuel: A MILP model for an Ammonia-Powered Shipping Network

The consequences of climate change are becoming more and more visible. A significant cause of this is CO2 emissions; the shipping sector is responsible for 3% of global CO2 emissions. As a result, the Fourth IMO GHG Study 2020 presents pathways to reduce the GHG emission of the shipping industry by 50% by 2050. Recent IMO goals have overtaken...

Design of an Ammonia Bunker Installation for Sea-going Vessels: A Best Worst Method Approach

The use of petroleum-based fuels in the shipping sector creates harmful emissions that need to be reduced to reach climate goals. Ammonia is being considered as a possible fuel to reduce emissions, but there exist several challenges that prevent its implementation. Research into these several of these challenges is being done, but there is...

Ammonia bunkering and storage for the maritime industry during a global ammonia transition

The worlds awareness of our emissions and the effect it has on our surroundings is increasing. This influences efforts to put new agreements into place to reduce emissions and the effects on global warming. Along with the Paris agreements, the International Maritime Organisation also came with measures to achieve these needed reductions of...

Zero-emission Fueling Infrastructure for IWT: Optimizing the Connection between Upstream Energy Supply and Downstream Energy Demand

A key challenge in the energy transition for Inland Water Transport is the functional design of bunker networks and first-order dimensioning of individual bunker stations. A fundamental ingredient for this is an improved understanding of how upstream energy supply (‘well-to-bunker-station’) and downstream demand (‘bunker-station-to-tank’) may...

Corridor Scale Planning of Bunker Infrastructure for Zero-Emission Energy Sources in Inland Waterway Transport

The availability of supporting bunker infrastructure for zero-emission energy sources will be key to accommodate zero-emission inland waterway transport (IWT). However, it remains unclear which (mix of) zero-emission energy sources to prepare for, and how to plan the bunker infrastructure in relative positions and required capacity at corridor...

Parametric Modelling Method based on Knowledge Based Engineering: The LNG Bunkering Vessel Case

This thesis aims in the development of a parametric modelling method for the preliminary ship design based on Knowledge Based Engineering (KBE). The research work was conducted in cooperation with C-Job Naval Architects. Nowadays, parametric models can be seen as the core of the design practice since they facilitate the exploration of the...

Waiting: Imagining the future of military architecture of the Atlantic Wall in a dynamic landscape of Wadden Sea.

The Atlantic Wall bunker ruins stand on the coast, abandoned and falling apart. There is a kind of beauty in this scene. <br/><br/>Contradiction between the rough concrete volumes defeated by asoft, ephemeral and seemingly delicate mass of water was the beginning of the research. Analysing the biggest territorial scale -the North Sea- the notion...

Sulphur emission regulation: Changing the market for bunker fuels - Exploring the future under new IMO-regulations and their impact on Vopak’s bunker fuel business

Drivers, Options and Approaches for Two Seaport Authorities on the Joint Reduction of Bunker Oil Related Emissions

The international agreements, made by International Maritime Organization in 2008 are an encouraging start to reduce the SO2 emissions caused by the use of bunker oil. Port authorities are confronted with a dilemma. From an environmental point of view, a proactive attitude is preferred. However, a unilateral initiative may jeopardize their...

Reduction of bunker oil related emissions through cooperation between two seaports

The international agreements, made by International Maritime Organization in 2008 are an encouraging start to reduce the SO2 emissions caused by the use of bunker oil. Port authorities are confronted with a dilemma. From an environmental point of view a proactive attitude is preferred. However, a unilateral initiative may jeopardize their bunker...
