摘要
半潜式钻井平台是深海油气资源开发的重要装备。我国目前有13座半潜式钻井平台在役,世界上有243座半潜式钻井平台在役,平台数量的增多需要有更多的维护升级技术做支持。为了提高平台的作业性能,提高平台的投资产出比,半潜式钻井平台在全生命周期中通常会经历多次升级改造。研究分析了半潜式钻井平台的常见改造升级目的,举例论述了几种主流平台改造方案,分析了不同改造方案对船体结构的影响。针对我国现役半潜式钻井平台,提出了几点改造升级建议,为平台的升级改造及退役再利用提供参考。
Semi-submersible drilling rig plays an important role in the development of offshore oil gas.There are 243semi-submersible drilling rigs all over the world and 13 in China,more rigs need more technical support.Most of the rigs experienced updates and conversions in its lifespan to improve the operation performance and efficiency.Different update purposes have been studied also some conversion plans.Main changes which happened to the rigs encountered with updates and conversions have been summarized.Some proposals have been made for the application to over own drilling rigs.
