摘　　要：在考虑海洋工程装备在极端海况和运行海况下的载荷与受力,风载荷也是一个不可忽视的因素。目前物理模型试验仍是研究海洋工程结构物载荷与运动性能的重要手段,而深海结构物在水平漂移运动较大,如何在较大范围内得到满足试验要求的风场,是提高试验能力的重要问题。应用数值计算方法对大范围的风场模拟进行了分析,并进行了相应的物理实验,在此基础上对海洋工程试验的风场模拟提出了若干建议。With the rapid development of offshore engineering, the offshore structures, such as FPSO and semi-submersible platform, encounter more extreme environments. Meanwhile, the superstructures of FPSO become larger and the wind area increases. The wind load on the vessels and platforms should be calculated carefully. In the model test for deepwater offshore structures, as the horizontal movement is quite large, the simulation of suitable wind field is very important. We use the numerical simulation and model test to analyze the wind field simulated in the offshore basin, and give some suggestions in this paper.
