In recent years, the operating sea area of oil-drilling vessels approaches deeper continental shelves. Therefore, instead of the mooring system by use of anchor-chain or wire rope which is difficult to use in deeper sea area, the "DPS" (dynamic positioning system) has been interested in the ship positioning in the deep sea area. In this study, dynamic positioning control tests were carried out on a platform model of semi-submersible two-lower hull type in the simulated environment of current and wave generated in the Offshore structure experimental basin, Ship Research Institute. Prior to the control test, the fundamental characteristics of platform and propulsion system were measured by the elemental model test. The results of overall control tests indicated that the "DPS" is duly practicable at the semi-submersible two-lower hull type platform.
