Underwater Thrusters Installation for Dynamic Positioning System of Offshore Floating Vessel
Advanced offshore floating structure utilizes dynamic positioning system to guarantee its automatic positioning without mooring system, realizing the offshore positioning requirements. The thruster is the key component of DP whose installation method directly affects the operation of DP and positioning accuracy of offshore floating structure. Based on the analysis of underwater installation methods of the existing large equipment, the paper proposes a new installation method of the large thrusters, using the L-shape floating platform as shift, orientation and position adjustment of thrusters. The new method can complete the precise position matching and installation of thrusters in the bottom of the structure.
