深水半潜式平台锚泊系统动力响应研究

摘要

A deepwater semi-submersible dril ing platform that works in the depth of 1 500 meters is studied in this paper. The ex￣pression model for wind,wave and flow along with their characteristic parameters in space and time is established. The time￣domain coupled analysis of the mooring system of this platform is carried out,and the impact of the platform’ s dynamic response in the di￣rections of six degrees on the platform’ s stability and the effect of different anchoring methods on the tension distribution of mooring lines are gained. These results can provide a foundation for time￣domain coupled analysis of deepwater anchor mooring positioning system and give further model and date support to the platform’ s safe operation.%以一座工作水深为1500 m的深水半潜式海洋平台为研究对象，建立了风、浪、流随其特征参数在空间和时间区域内的表述模型，对平台进行锚泊系统时域耦合分析，找出了平台在六个自由度方向的动力响应对平台稳定性的影响程度以及布锚方式对系泊线张力分布的影响，为深水锚泊定位系统时域耦合分析提供方法基础，并能够进一步为平台的安全性能运营管理提供模型和数据支持。
