Influence of Charging Infrastructure on the Daily Energy Use of Vessels with a Variable Operational Profile

In the global energy transition where the shift from fossil fuels to renewable energy is needed, wind energy is a growing industry. In the offshore wind industry, Service Operation Vessels (SOVs) are needed to operate and maintain wind farms. To reduce the environmental footprint of SOVs at offshore wind farms, the possibility of battery...

Estimate vessel emissions in ports using AIS data: A study to identify emission distribution patterns in ports and evaluate emission reduction strategies

The shipping industry is responsible for almost 3% of the world's greenhouse gas emissions and is looking for possibilities to reduce their share. The demand for lowering the emissions of the maritime industry creates the need for insight in the emissions. Currently a generic method to specify emissions in space and time, as a function of vessel...

Photovoltaic potential of the Dutch shipping fleet: Experimentally validated method based on photovoltaic power calculations to simulate the energy yield of general cargo inland vessels

Implementing renewable energy generation and more sustainable consumption behaviour in the future inland shipping industry is necessary. Electrification of the inland shipping fleet leads to an increase in electrical energy demand on the consumption side. The generation of decentralized photovoltaic (PV) energy systems on board of general cargo...

A study on the possibilities of using a coupled or schematized numerical method to determine the flow pattern downstream of a discharge sluice: An Ostend case study

In the port of Ostend a discharge sluice is going to be constructed as part of an enforced dike ring. The proposed location of this discharge sluice is close to an already existing marina, the Royal Yachtclub Oostende (RYCO), and hindrance is expected regarding the outflow of the sluice in marina direction. When designing the sluice, an optimal...

An experimental and numerical investigation of the hydrodynamics of the ducted system of a "Van Rompay Turbine": with the goal to capture energy from the current of an ocean, river, estuary or similar

Hydrokinetic energy is an environmentally friendly source of electricity and it has the advantage to be more predictable compared to other renewables. According to IRENA (2020), the capacity of converting hydrokinetic energy into electricity is expected to increase in the coming decades as many concepts are in the pipeline. One of these...

Mapping port operability indicators across the world: Screening the suitability of port locations related to metocean conditions

Parametric design-tool to optimize preliminary design of navigation lock chambers

Summary<br/>In the twentieth century a substantial number of navigation locks were build in the Netherlands. The navigation locks built in that era mostly had a life span of 80 to 100 years. This means that in the coming years most of these locks will be in need of either renovation or replacement. Rijkswaterstaat, the administrator of most of...
