Slide analysis and control of jack-up rig during repeat placement

  • 自升式钻井平台在东海的作业量随着西湖地区勘探开发的不断发展而在增加。因受台风影响及在同一地点多次作业的原因,自升式钻井平台不可避免地会在上一次作业位置附近重复作业,引起桩靴滑移现象,可能造成就位后悬臂梁覆盖能力下降,无法满足钻井作业需求,甚至影响平台结构安全,造成工程事故,大大增加了作业风险。本文以H9自升式钻井平台桩靴为例,分析了桩靴部分重合工况下的受力特点,研究了海底土体破坏形式,提出了不同类型土质条件下的桩靴水平力计算模型,并利用滑移线有限差分法近似计算桩靴极限载荷。对H9平台在现场重复就位时采取的措施进行了分析,并根据海上作业要求提出了一系列安全控制措施,为安全高效地实现平台重复就位提供了参考。
