Year: 2015 Issue: 6
Journal: China Offshore Platform
Keyword: new semi-submersible platform; AQWA; hydrodynamic analysis; time-domain analysis;
Abstract: Firstly,in order to make the compensation for the active deepwater semi-submersible platform,which produce heave error in the deep flow and storms.A new type of semi-submersible platform is designed and the three-dimensional hydrodynamic model is made;Secondly,the water dynamic analysis of the target platform is carried out in the frequency domain depending on the AQWA,and the motion response of the platform is obtained;Finally,according to the code for design of a new type of semi submersible platform mooring system,on the platform and mooring system are time domain coupled analysis,providing a precise prediction for the control of the target platform to ensure real-time stability,and to improve operators’ comfort.
