Paper

Hydroelastic effects during slamming of high-speed marine vehicles affect the development of the pressure along their bottom. The aim of this study is to investigate coupling process of a novel CFD method and a FEM structural solver for simulation of hydroelastic slamming. As slamming is characterised by violent and strongly nonlinear fluid–structure interaction, the flow solver is based on a...

Seakeeping, Hydrodynamics

Paper

In the tradition dating back from the 1970ties, time-domain strip approaches have been used to investigate the seakeeping performance of planing High Speed Craft, HSC. The geometrical starting point is prismatic hulls and main issues addressed, have been design-loads and a representative design-acceleration. Usually, design is interpreted as some sort of maximum or limiting value. This has...

Seakeeping, Hydrodynamics

Paper

The repeated wave slamming experienced by high-speed planing craft can cause structural damage and discomfort or injury to passengers and crew. The design guidelines related to structural and seakeeping considerations are still mainly determined through semi-empirical criteria that can lack physical meaning or are limited in application. The research presented here is party of a study to...
