THE USE OF THE SPECTRAL OCEAN WAVE MODEL (SOWM) IN PREDICTING SHIP RESPONSES

This report points out the need for better ocean wave data for use in ship design, weather routing of ships and day-to-day vessel operation. The Spectral Ocean Wave Model (SOWM) developed by the Navy's Fleet Numerical Weather Central has shown great promise as a means of routinely providing forecast wave spectra for ship operating purposes. After reviewing other work on the evaluation of the SOWM, this report attempts one type of evaluation--the comparison of hull stresses and accelerations measured on the SS LASH ITALIA by its onboard instrumentation with those calculated using directional sea spectra produced by the SOWM and calculated RAOs.
