An actual ship test of the container ship "Kurobe-Maru (D.W. abt. 32,000 tons)" of N.Y.K. Lines, was carried out under the voyage between Tokyo and New York, from Dec. 5, 1975 to Jan. 25, 1976. The main object of the test was to collect data about the characteristics of load acting on the propulsive shafting of the twin-screw container ship. Torque of shafts, number of revolution of shafts, bending moment of shaft, pitch, roll, vertical and lateral accelerations at the aft position and the instruments room, rudder angle, were measured and recorded. After analyses of the data following results are obtained. (1) The variations of the torque and bending moment of sheft are influenced by pitch rather than roll. When the ship navigates in heavy pitch condition, the torque and bending moment of shaft fluctuate at the same period of the pitch frequency. (2) According to shaft-bearing insulation test, it is considered that shaft contact on the sterntube bearing occurs at shaft speed below about 24rpm.
