南海极浅水下浮式平台锚泊系统数值计算和模型试验对比

Comparative study on numerical calculation and model test of mooring system of floating platform in South China Sea

依托南海近岛礁地形,设计了一套悬链线式平台锚泊定位系统。通过数值计算结果和模型试验结果进行对比,分析该锚泊系统的定位能力。试验模拟了各种风浪流等海洋条件,详叙了模型试验的具体过程。通过对比分析数值计算和模型试验的统计数据,分析数据差异的原因,以期较为准确地预报该半潜平台作业时的运动和受力情况,同时也验证了所设计锚泊系统的可行性,为今后新平台和新锚泊方式的开发设计提供依据。

Based on the topography of the near-island reef in the South China Sea,this paper.designs a catenary mooring system,and analyzes the positioning ability of the mooring system by compared numerical calculation and model test.The model test simulates a variety of marine storm flow conditions.This paper describes the process of model test.By comparing the data of the numerical calculation and the model test,the reason of the difference of the data is found in order to predict the movement and the force of the semi-submersible platform more accurately.At the same time,the feasibility of the mooring system is verified and this paper provide the basis for the development and design of new platform and new mooring method in the future.
