Global distribution and risk to shipping of very extreme sea states ( VESS)
ABSTRACT The impact of extreme sea states on offshore infrastructure is of intense interest in the ocean engineering community at the present time. In this study, a new quality‐controlled database of global satellite‐derived estimates of significant wave height ( HS ) and surface marine wind speed f...

ABSTRACT The impact of extreme sea states on offshore infrastructure is of intense interest in the ocean engineering community at the present time.
