Mild-Slope Wave Modelling for Dynamic Mooring Analyses: An exploratory study into an efficient alternative to the wave penetration model

Moored vessels in harbours around the world are affected by waves penetrating into the port basin. Hydraulic conditions can lead to severe vessel motions that influence the (un)loading efficiency and can even lead to the failure of fenders and mooring lines, creating unsafe situations for operating staff and <br/>A DMA is a chain of numerical...

Vertical Motion Simulation Of A DTMB 5415M Ship In Head Sea Using The Variational Multi-scale Method

This master thesis presents the computation of free-surface flow phenomena with emphasis on ship hydromechanics. We perform a simulation of the heave and the pitch motion of the DTMB 5415M ship moving in head sea. To this purpose we employ an existing Arbitrary-Lagrangian-Eulerian residual-based variational multiscale method (ALE-RBVMS) to...

Determining and predicting the seakeeping performance of ships based on jerk in the ship motions

The comfort assessment of ships is based on several criteria. There are for example criteria for motions, noise and vibrations. The criteria for motions are nowadays often defined as comfort limits on the accelerations in the ship motions. However, from other industries it followed that the rate of change of the accelerations, the jerk, can also...
