Alternative strip method for a laterally drifting ship in waves

This thesis describes a study on an alternative strip method for a laterally drifting ship in waves. Currently, in an attempt the seakeeping performance, Faizul A. A. (2006) has included the lateral drift caused by wind forces and/or wave drifting forces in his studies of New Strip Method. Thereby,...
