DRIFT FORCES AND SLOWLY VARYING FORCES ON SHIPS AND OFFSHORE STRUCTURES IN WAVES

A survey of numerical methods used to calculate drift forces and moments on ships or other marine structures in regular and irregular waves is presented. Methods to calculate slow drift excitation forces in waves are also included. Results for drift forces and moments for different objects in beam, head and oblique sea are given. Eight different methods are used. Values for second-order difference frequency force due to presence of two simultaneous regular wave components are presented.
