The under water ventilation of methanol vapour: A numerical investigation

In order to meet the shipping industry's emissions reduction goals, it is imperative to explore and adopt alternative marine fuels. Methanol (or methyl alcohol) is expected to play a large role in the future. However, current regulations limit the attractiveness of methanol as marine fuel due to the inability to use the space around a venting...

Design and Feasibility of a 30- To 40-Knot Emission-Free Ferry

Internal combustion engine (ICE) emissions cause numerous social, environmental, health, and economic issues, including extreme weather or harm to public health. These effects are also experienced in the Chinese Pearl River Delta, where a high-speed, 200-passenger ferry named the Coastal Cruiser 200 (CC-200) uses ICEs to operate. The CC-200's...

Feasibility study of a flexible floating solar concept as energy supply for Sleipnir during operations: focused on the hydrodynamic behaviour

The electricity demand increases globally and requires a shift toward renewable sources to prevent the exhaustion of the planet. The shipping industry is responsible for 2-3 % of the global Greenhouse Gas emissions and Heerema Marine Contractors (HMC) identified floating solar as a promising solution to reduce the emissions, of their crane...

Ship Motion Predictions in the Time Domain: using identified linear and non-linear force coefficients

Deterministic predictions of wave induced ship motion are increasingly often used to enlarge the oper- ational envelope of ships that perform complex operations at open sea. The large amount of complex operations performed nowadays, motivates the relevance of motion predictions. The company Next Ocean provides these forecasts, based on linear...

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 approach for using monitoring data to make a propulsion line model used for hardware-in-the-loop simulations

Monohull versus Semi-submersible for offshore heavy lift crane operations

In this thesis the differences between the monohull and semi-submersible are investigated. For a general heavy lift crane operation and its operational profile, the difference is performance and total cost are calculated. These are used to determine the turning point, the point where the semi-submersible is more favourable for a heavy lift crane...
