Heerema Marine Contractors is constructing a new semi-submersible crane vessel, the Sleipnir. Due to low initial stability, semi-submersibles may present significant wave induced resonant motions in heave, roll and pitch. For practical reasons, especially the roll motion could play a limiting factor for future lift operations of the Sleipnir. In...

This thesis describes the mechanisms with which tip vortex cavitation is responsible for broadband pressure fluctuations on ship propellers. Hypotheses for these are described in detail by Bosschers (2009). Validation is provided by three main cavitation-tunnel experiments, one on a model propeller and two on a stationary wing. These have...

In the design of mooring systems, it is a common practice to use a 100-year design environment to calculate extreme responses. Statistical inference is executed on the environmental data to produce a 100-year environment. This 100-year environment is then simulated to calculate the loads that occur when the vessel is under the influence of the...

Dockwise started in 2008 with the OCTOPUS motion monitoring and captain decision support system for performance optimization and bad weather routing capacity. The OCTOPUS-Onboard system gathers weather and motion data, which is collected in the OCTOPUS database. This database includes the encountered weather data and the measured accelerations...
