ANALYSIS OF NON-LINEAR VESSEL MOTIONS: EXPERIMENTS AND PREDICTIONS

This paper presents a study into the wave height dependence of the motions of a high speed displacement craft and a hull with significant flare and overhang. A series of seakeeping towing tank experiments on these craft has been performed with the objective of determining the wave height dependence of their vertical motions. A pseudo non-linear strip theory is presented which models effects not treated by linear strip theory, including the Kelvin (ship generated) wave pattern, emergence of the bow or stern due to motions, the profile of the incident wave and the amplitude and phasing of the resultant motions. It is shown that consideration of these effects may have a significant influence on predicted motions, particularly for large wave heights.
