Theoretical Prediction of Dynamic Wave Loads on Small-Waterplane-Area, Twin-Hull Ships.
Abstract
A mathematical model and computer program have recently been developed to predict the bending moment, sideload, and vertical shear force acting on the cross structure and strut of twin-hull ships in beam waves. The computer program has been used to predict these loads for a variety of small waterplane-area, twin-hull (SWATH) ships, and good agreement with experimental data confirms the basic validity of the prediction technique. The prominent feature of sideload and transverse bending-moment responses for SWATH ships is a sharp peak resulting from wave diffraction at an excitation wavelength roughly three to four times the maximum overall beam of the ship.
