Abstract [en]

The methods for structure design of high-speed craft available in the class Wcation societies' scantling codes and various standards are well established and easy to use. They are however limited in a number of aspects, for example regarding the consideration of the actual operational profile of the craft and the crew working conditions and safety. The drastic simplf1cation of the slamming loads and the related uncertainties inherited in the semi-empirical background further limits the options for structure optimization. The alternative would be the establishment of direct calculation methods. The involved fluid-structure and craft-crew interactions, and the generally complex operation of high-speed craft, however imply great challenges. This paper reviews methods for time-domain simulation of craft motions, structure responses and crew environment for high-speed craft in irregular waves that are currently under development. An approach for using these methods for calculating extreme responses and analyzing crew and structure capacities with detailed consideration of the craft intended operation is outlined and the way forward for establishing a simulation based design approach is discussed.
