摘要
深水半潜式平台经常面临复杂恶劣的海洋环境条件,破坏力巨大的波浪砰击载荷对海洋平台的结构及工作人员安全造成巨大的威胁。本文采用模型试验的方法对半潜式钻井平台受到的波浪砰击载荷进行了研究,通过设计专用的测量单元对波浪砰击载荷进行监测。根据试验结果,系统地分析了半潜式钻井平台在不同浪向下的波浪砰击载荷及其空间分布。研究表明:横浪环境中,波浪砰击最为严重,迎浪次之,而斜浪条件下的波浪砰击载荷大小和砰击频率相对缓和;砰击载荷在空间上主要分布在水线上方一定区域,具有明显的三维特征。
impact loads which threaten the structural integrity and staff's safety.In this paper,wave impact loads on a semi-submersible drilling platform are studied experimentally.Measurement units were designed specially to monitor wave impact loads.According to the experimental datum,sensitivity of wave impact loads with respect to wave headings and the spatial distributions of wave impact loads were systematically analyzed.The results show that the platform under the beam seas and head seas is exposed to more serious wave impacts than oblique seas.Wave impact loads mainly concentrate on some area above the waterline and show obvious three-dimensional effect.
