AbstractThis paper presents results of numerical predications of the ability of a Z-drive propulsion system to affect roll stabilization of a vessel moving at steady speed in regular seas. The potential flow based, time domain, seakeeping and maneuvering code MOTSIM was used to evaluate the effectiveness of a twin Z-drive propulsion system on a vessel to control roll motions in regular seas. Results for several headings and wave characteristics were generated and compared with the roll reduction capabilities of a conventional rudder/propeller system on the same vessel.
