Abstract
With the increasing water depth, semi-submersible platform mooring system weight has increased rapidly. Because the coupling of the platform and mooring system will directly affect the safety of platform location, the mooring system must use the design of multi-component mooring line. The paper introduces coupled time domain analysis theory of platform and mooring system, and then uses AQWA software to build the three-dimensional hydrodynamic model of the 981 Semi-submersible Platform. MATLAB is used for the multi-component mooring system design calculations. The load is applied to the model of the marine environment in the South China. It studies its changes with top angle of tension mooring system and platform offset, and finally checks the platform safety. Ultimately it determines a reasonable horizontal inclination at the top of mooring lines. Check and assess mooring positioning system of the 981 platform once in a century environmental loads. This paper has a positive meaning to optimization of 981 semi-submersible drilling platform mooring system at the deep water state, pre-anchor operation and positioning system security evaluation.
