Advances in Environment Specification for Seakeeping Analyses,

Abstract

Substantial progress has been made in the specification of environmental statistics since the 19th ATTC in 1980. For the first time, reliable wind and wave statistics for the Northern Hemisphere are available. While the characteristics of wave directionality are still elusive some progress has been made in the quantification of spectral spreading. New stratified sampling techniques provide a statistically unbiased sample of directional wave spectra representative of all sea severities and ocean areas. The modified JONSWAP and the Wallops idealized spectral formulations offer alternative methods to the commonly applied Bretschneider family for applying surface wave spectra in seakeeping analyses. This paper provides highlights of these advances.
