The increase in fuel prices has initiated considerable interest by ship operators in new ship autopilots which minimize the propulsion losses due to steering. This research presents the results of work on a steering design for the Mariner class ship based on a computer simulation. A model of the Mariner class ship was coupled to a function minimization subroutine to minimize the added resistance caused by rudder activity and hull drag of inertial origins caused by periodic yawing of ship in seaway. The Mariner class ship computer model was tested in calm water and in seaway. The optimal controller parameters are shown in look up tables as functions of ship speed, sea state, encounter angle and encounter frequency. This technique can be used as an adaptive controller.
