Abstract

The optimization of ship response to waves is reconsidered due to the fact that the concept of a design spectrum cannot adequately characterize the real ensemble of widely varying sea states. An examples based on JONSWAP data illustrates the strong dependence of the response statistics on the assumed sea state ensemble. It was concluded that some parametrization techniques need to be developed to reduce the information content of high-resolution forecasting models to the level required for statistical applications.
