Evaluating Emissions of Offshore Transportation Vessels

The offshore wind market is growing rapidly, and new offshore wind projects are being launched more than ever. To keep up with demand, parts for these wind turbines are being produced all over the world. To get all the parts needed to their destination on time, they must be transported on heavy transport vessels (HTVs).<br/><br/>Today, business...

Technical and economical feasibility of zero-emission walk to work vessels

Urgent action is needed to decrease maritime emissions. The renewable wind energy sector must also decrease its life cycle greenhouse gas (GHG) emissions. Total GHG emissions from offshore wind turbines are approximately 120% more compared to onshore wind turbines. Moreover, it is estimated that Walk to Work (W2W) vessels are responsible for 3.3...

Hydrogen powered propulsion for an offshore crane vessel: A technical and economical evaluation

The International Maritime Organisation (IMO) has set the goal to reduce the total annual greenhouse gas emissions from international shipping by at least 50% by 2050 compared to 2008. For this reason, shipowners will have to innovate the drive-trains and energy systems of their vessels to reduce harmfull emissions. To achieve this goal,...

Methanol Hybrid Offshore Working Vessels: A technical, environmental and economic assessment

To support Van Oord’s path towards a low-emission future fleet, this thesis has focused on the technical, environmental and economic impact of a methanol hybrid power plant design for new-build offshore working vessels (OWVs). These Dynamic-Positioning (DP) vessels are known for their large and dynamic power plants and have to limit their NOx...

The feasibility of zero-emission ferries in the Wadden Sea

In 2015, the worlds first zero-emission sea-going ferry was launched in Norway. This ferry, MF Ampere, is powered by batteries and is sailing in an UNESCO World Heritage Site. In the Netherlands, the Wadden Sea is an UNESCO World Heritage Site with multiple ferry routes where the most recent ferries are sailing on natural gas to reduce emissions...

Alternative fuels on board of carbon-neutral cruise vessels: The selection, implementation and design impact of alternative fuels on board of carbon-neutral cruise vessels

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...

Batteryboat: An effective solution to store and transport solar energy

Climate change, depletion of fossil fuels, and economic concerns are among the main drivers of sustainable energy transition. The Netherlands has drawn up ambitious goals in the energy transition. However, numerous studies have shown that there is a lack of space in the Netherlands to adapt to a 100% green economy. To solve this dilemma it is...
