In order to estimate the manoeuvrability of the new training ship Wakashio-maru IV, in which a bow thruster and a stern thruster were installed, some model tests were carried out. This paper mainly deals with experimental results of side thruster model tests and the hydrodynamic mathematical models of side thrusters which the authors proposed. The side thruster model tests consisted of the following 7 kinds of tests. (1) Propeller open tests on the side thruster impeller model. (2) Side thruster model tests with 0m/s towing velocity. (3) Side thruster model tests installed in the 1m model ship with 0m/s circulating water velocity. (4) Side thruster model tests installed in the 3m model ship of Wakashio-maru under longitudinal motions. (5) Pressure distribution measurements around the thruster nozzles on the thruster model installed in the 1m model ship under longitudinal motions. (6) Side thruster model tests installed in the 3m model ship of Wakashio-maru under oblique motions. (7) Pressure distribution measurements around the thruster nozzles on the thruster model installed in the 1m model ship under oblique motions. Results of the above side thruster model tests shows the accuracy and usefulness of the proposed hydrodynamic mathematical model of side thrusters.
