Abstract
A computer program package for assessing the seakeeping performance of SWATH ships is described. This package is based on an existing ship motion computer program, SWATM2. The seakeeping performance analysis process is automated and combined with a recently-published North Atlantic wave data base. The resulting package performs the following functions: (1) Computes ship motions for the entire range of sea conditions for a user-specified ocean area in the North Atlantic. (2) Applies seakeeping criteria to compute seakeeping performance parameters, such as maximum sustainable speed and maximum effective speed, for each heading and sea condition. (3) Averages the seakeeping performance parameters over all headings to obtain mean values for each sea condition.
