Results are presented from a fundamental research effort directed to identification and minimization of energy losses related to ship steering. The paper attempts to evaluate the energy losses related to yawing and rudder activity of ships during open-seas course-keeping in deep water. Two different representative tankers and one containership are examined, using hydrodynamic data resulting from captive model tests. The approach presented involves frequency domain analyses and time domain computer simulation studies of the yaw-sway-surge-rudder coupled motions of the ships. Evaluation of losses due to both yawing of the uncontrolled ship and those resulting from yawing and rudder effects in the automatically steered case are made. 42 refs.
