The influence of ship size, afterbody shape and propeller rate of revolution on the propulsion, cavitation and pressure fluctuation properties of a full-formed tanker was studied at SSPA in 1971-72. The shaft power and propeller rpm were first predicted from resistance, self propulsion and open water tests with 7 m long models in the towing tank. The same models were then tested in SSPA large cavitation tunnel where the wake was measured, the flow around the stern and the cavitation patterns were observed and the vibratory pressures at the hull above the propeller were recorded and analyzed.
