圆筒式平台在复杂的海洋环境面临诸多挑战，其垂荡运动性能不足，直接制约了干式采油树的安装与使用。基于三维势流理论，以深水圆筒式干树平台为研究对象，在时域和频域上分析不同工况下平台的水动力特性和系泊系统性能，并进行相应的模型试验。结果表明，浪向角对平台运动具有显著影响，其中系泊缆张力波动与纵摇运动密切相关；此外，系泊系统设计符合CCS相关标准。研究结果为新型圆筒式干树平台的性能优化提供参考。
The cylindrical platform faces many challenges in the complex marine environment, and its heave motion is insufficient, which directly restricts the installation and use of dry tree system. Based on the three-dimensional potential flow theory, the hydrodynamic characteristics and mooring system performance of deep-water cylindrical dry tree platform were analyzed in time domain and frequency domain, and the corresponding model tests were carried out. The results show that the wave direction has a significant effect on the platform motion, and the mooring tension fluctuation is closely related to the pitch motion. In addition, the mooring system is designed to meet CCS standards. The research results of this paper provide reference for the performance optimization of the new cylindrical dry tree platform.
