摘　　要：为研究分析系泊浮式生产储油平台波浪漂移力计算精度和耦合运动时域模拟的方法,本文使用自主开发的一阶泰勒展开边界元方法对某浮式生产储油平台在压载工况下的频域波浪漂移力进行了计算,并与商业软件AQWA、WAMIT计算的漂移力结果作对比分析。在频域计算的基础上,使用基于异步耦合方法开发的系泊浮体耦合运动分析程序对浮式生产储油平台在多个不规则波海况下的非线性运动响应进行时域模拟,并与模型试验测试结果作对比,分析了数值模拟精度。从结果显示可知计算结果吻合较好,即使是更为复杂的海况,在海浪和海流同向的情况下,异步耦合分析程序也能获得与模型试验较为一致的结果。To study the precision of wave drift force and the coupled motion time domain simulation method of a moored floating production storage and offloading system(FPSO),a self-developed first-order Taylor Expansion Boundary Element Method was used to calculate the wave drift force in the frequency domain of the FPSO under ballast conditions.The calculation result was analyzed and compared with the drift force calculated using commercial software(AQWA and WAMIT).Based on the frequency domain calculation,the nonlinear motion response of the FPSO under multiple irregular wave sea conditions was simulated in the time domain by using the coupled motion analysis program of mooring a floating body developed using the asynchronous coupling method.The numerical simulation accuracy was analyzed and was in good agreement with the model test results.For more complex sea states,the asynchronous coupling analysis program can obtain results consistent with the model test even when the waves and currents are moving in the same direction.
