半潜式平台波浪砰击分析与应用

Wave Slamming Analysis and Application for Semi-Submersible Platform

针对半潜式平台波浪砰击问题,提出砰击分析流程,并针对波浪砰击的局部完整性,阐明砰击时间历程法与楔形块入水法两种砰击强度分析方法的基本原理、校核准则及适用范围。以某半潜式钻井平台为例,对两种波浪砰击分析方法进行对比验证,阐明各自的优缺点,给出半潜式平台侧板砰击与底板砰击所适用的分析方法。这些方法可为设计人员和操作人员提供有用的指导。

Aiming at the problem of wave slamming of semi-submersible platform,the analysis process of wave slamming is proposed.Aiming at the local integrity of wave slamming,the basic principle,verification criteria and application scope of two analysis methods for slamming strength,the time-history method and wedge block water entry method,are expounded.Taken a semi-submersible platform as an example,the two slamming strength analysis methods are compared and verified.Their advantages and disadvantages are clarified.The applicable analysis methods of side slamming and bottom slamming are given.The methods can provide useful guidance for the designers and operators.
