Abstract

In recent years, great progress has been made in both the optimisation of the seakeeping behaviour of fast ships and the development of efficient numerical methods for computation of the seakeeping behaviour of ships in general. The study presented in the thesis aims to integrate both developments. First, the key aspects of the seakeeping behaviour of fast vessels are identified, as well as their influence on the operability of these vessels at sea. Subsequently, a numerical approach is developed that is specifically aimed at the seakeeping of fast vessels. Next, a validation study of the numerical method is described, that makes use of extensive experimental data obtained by means of seakeeping model tests. The validation study leads to the conclusion that the method can satisfactorily predict the overall motions of high speed ships in waves, but still lacks in the prediction of peaks in the vertical acceleration levels associated with impacts of the ship in waves. A number of possibilities is discussed to include these impacts.
