以菱形立柱式半潜平台为研究对象，首先通过对比数值结果与试验结果验证本文所采用的数值分析模型的正确性。在此基础上，对该新型半潜平台开展时域分析，研究在恶劣海况下平台的运动性能和系泊系统性能。最后，开展谱分析和敏感性分析以探究该新型半潜平台的水动力机理。研究表明，该新型半潜平台在恶劣海况下仍具有优异性能，可为南海深远海油气资源开发提供新思路。
A semi-submersible platform with rhombic columns is numerically investigated. The numerical results and experimental results are compared to validate the numerical model employed in the present study. Then, the time-domain analysis are conducted to investigate the motion performance and mooring performance of the novel platform under extreme sea condition. Finally, the spectral analysis and sensitivity analysis are carried out to study the hydrodynamic principle of the novel platform. The results indicate that the novel platform under extreme sea condition has a superior performance and is able to provide a new method for the oil and gas development in the South China Sea.
