FPSO是海上一种浮式装置，用于对开采的海洋油气资源进行储存和加工。在我国南海布置的FPSO经常会受到台风影响而降低其安全性。针对中国南海恩平海域某FPSO，研究其在2018年强台风“山竹”下的抗风浪能力。基于三维势流理论方法，建立FPSO及单点系泊模型并进行船体的运动响应分析及系泊链的安全性校核。对其布置的输油立管分别进行单点不解脱情况下的立管位移分析和安全性校核，并设计一种2倍安全系数的立管布置形式来更好的满足立管在台风环境下的张紧和弯曲安全性，为台风环境下FPSO及其单点系泊系统的分析研究工作提供参考。
FPSO is a floating unit used to store and process offshore oil and gas resources. The FPSO deployed in the South China Sea is often affected by typhoons, which reduces its safety. The wind-wave resistance capability of an FPSO in Enping Sea area of the South China Sea was studied under the strong typhoon Mangokhut in 2018. Based on the three-dimensional potential flow theory, the FPSO and single point mooring model are established, and the motion response analysis of the hull and the safety check of the mooring chain are carried out. The displacement analysis and safety check of the oil transmission risers arranged in the pipeline were carried out respectively under the condition of single point non-release, and a risers arrangement based on safety factor of 2 was designed to better meet the tensioning and bending safety of the risers under typhoon environment, providing a reference for the analysis and research of FPSO and its single point mooring system in typhoon environment.
