| 摘 要： | 对一新型深海半潜式生产平台的水动力性能进行模型试验和数值计算分析.与传统直立柱结构的半潜式平台不同，该新型平台的4根立柱在水线面以上向内倾斜.由于平台工作水深为1.5 km，模型试验时需通过数值分析进行等效截断设计.对平台6自由度运动响应和系泊缆受力的研究表明，模型试验结果与数值计算结果基本一致，该新型半潜式生产平台具有良好的水动力性能，满足规范要求.

| Abstract: | For a new concept semi-submersible platform with four oblique columns above the water surface, both the model test in the deepwater offshore basin and numerical analyses were carried out to study the hydrodynamic performance. The water depth is 1.5 km and the spread mooring system has to be truncated equivalently for the model test. The hydrodynamic performance in both operational and survival conditions was investigated by analyzing the 6 DOF motions and the mooring line tensions based on the experimental and numerical results. The agreement is generally well and the good hydrodynamic performance of the new concept semi-submersible platform satisfies the design requirements.
