ASSESSING THE SEAWORTHINESS OF SWATH SHIPS

Small Waterplane Area Twin Hull (SWATH) ships respond less to waves and have longer natural periods than conventional displacement ships. Careful design for seaworthiness is required because utilizing the design flexibility that creates the potential for good seaworthiness can inadvertently result in a hull form that is not seaworthy. A method has been developed to predict the responses of SWATH ships to waves, to generate hull forms with specified geometric and hydrostatic characteristics, to select fixed stabilizing fins that provide vertical plane stability at the ship's maximum speed and best reduce vertical plane motions, and to predict operability in the wave environment at various geographical locations. This paper presents and applies this method to facilitate exploration of the effect of hull form characteristics on performance at various operating conditions, and compares the ability of various hull forms to meet mission requirements.
