本文研究新型FDPSO在南海海况中的动力性能，重点分析垂荡板设置对浮体水动力的影响。以深水八角形FDPSO为对象，采用SESAM软件通过数值分析计算不同垂荡板布置下的浮体运动响应，验证频域内水动力性能的准确性，并通过时域耦合分析评估其在一年一遇和百年一遇海况下的表现。研究结果表明，单层垂荡板在抑制垂荡和减摇方面表现更优；对于双层垂荡板，综合考虑垂荡板增阻效应和恶劣海况下的出水问题，最终选择5 m间距，兼顾性能与安全性。
This study investigates the dynamic performance of a new FDPSO in the South China Sea, focusing on the impact of heave plate configurations on the floater's hydrodynamic performance. Using a deepwater octagonal FDPSO as the research subject, numerical simulations were performed with SESAM software to calculate the floater's motion response under various heave plate configurations, verifying the accuracy of hydrodynamic performance in the frequency domain. Time-domain coupling analyses were also conducted to evaluate its behavior under one-year and hundred-year return period sea conditions. The results indicate that the single-layer heave plate is more effective in suppressing heave and roll motions. For the double-layer heave plate, greater spacing improves suppression, with the theoretical optimal spacing being 8 meters. Additionally, the double-layer heave plate at an 8-meter spacing produces the lowest mooring chain forces, making it suitable for various sea conditions. However, considering the drag effect and potential emergence of the heave plate in severe conditions, a 5-meter spacing was ultimately chosen as the optimal compromise, balancing performance and safety.
