SHIPMO5: An Updated User's Manual Incorporating New Wave Spectra and Ship-Referenced Forces

Abstract

The ship motion computer program SHIPMO has been revised to increase its capabilities in several different areas. The new version of the program can compute forces relative to local ship axes and the resulting incidence of motion-induced interruptions or sliding events. Seakeeping positions may now be offset from the ship center-line. The program now includes expanded wave spectra capabilities, including multi-directional spectra. Motion computations may include hydrodynamic end effect terms, which can be important for transom stem ships at forward speeds. SHIPM05 also has an option for predicting propeller emergence, which can influence added power requirements.
