Abstract:

This report gives results of an extensive validation of DNDs strip theory program SHIPMO7 and the three-dimensional ship motion code PRECAL developed by Cooperative Research Ships. Ship motion and sea load predictions are compared with results for the CPF hydroelastic model, which was tested in regular and irregular waves in both head and oblique seas. In general, both codes give excellent agreement for ship motions and reasonable agreement for sea loads. In irregular head seas, PRECAL predicts over vertical bending moment at midships by an average of 9 percent, which is superior to the average prediction over by SHIPMO7 of 25 percent.
