| Abstract: | Taking the semi-submersible platform working in depth 1200m with 8 mooring platform as example to analyse the system positioning method-change the mooring line length in the mooring system. To establish multiple objective optimization models to react the semi submersible dynamic response system platform, this helps to get the ship target displacement and optimal mooring line length. With the help of interdisciplinary software iSIGHTand the optimization design of structural dynamic mooring system through the development of program interface, called hydrodynamic analysis software ANSYS/AQWA solver solutions to realize semi submersible platform response. Via analyzing semi submersible platform through wind, wave, flow hydrodynamic coupling under combined,real-time control of mooring line length to achieve the positioning of the platform and ensure the stability of the platform. |
