A Real-Time Location and Reset Method of Cylindrical FPSO
In this paper, a real-time location and reset method of cylindrical FPSO is presented based on GPS. In this method, the coordinate system of PFSO is determined by three GPS locators installed on the platform. Then, through coordinate transformation according to the marine engineering coordinate system established before, we can get the displacement and the orientation of FPSO, so as to achieve its real-time location. Finally, this displacement and orientation information is assigned to relative thrusters, which are evenly distributed with an angle 22.5°on both sides of the “+” and “-” X and Y axis, according to the calculating results of the optimization model.
