In order to investigate the propulsive performance of a pure car carrier, propeller open water tests under various conditions, wake surveys in still water, resistance tests and propeller load varying tests in still water as well as in regular head waves were carried out. As the results of the tests, following conclusions were obtained. 1) Propeller performance in regular head waves as well as at forced surge oscillations, concerning not only the mean values but also the time histories, can be expressed by using the results of propeller open water test. 2) Effects of the position of measuring plane, ship speed and rudder on the wake distributions were clarified. 3) Thrust deduction fraction defined by resistance under towing condition in waves did not agree with that in still water. 4) Propeller interaction factor Bo for hull of ship as well as Co for wake in waves were identical with those in still water.
