A MODIFIED STRIP THEORY FOR CALCULATING MOTION OF SHIPS WITH FORWARD SPEED

A modified strip theory formulation for practical seakeeping calculations is presented. It is based on a combination of a traditional strip theory with a local high-speed formulation in the bow region. The calculation of wave elevation close to the bow includes the effect of radiation and diffraction. Hence, important seakeeping parameters as green water on deck and slamming loads can be more accurately predicted. The method may be used in an early design phase or as a supplement to model testing.
