300英尺自升式平台设计技术

Design Technology of 300ft Self-Elevating Drilling Unit

随着世界经济的繁荣和科学技术的发展,石油作为重要的能源,用途越来越广泛,由此使有限的陆地石油资源已日见枯竭。石油开采商把目光纷纷投向海洋石油的开发。在海洋油气开发装备中,自升式平台由于能够适用于不同的海底土壤条件和较大的水深范围,同时移位灵活方便,便于建造,因此应用非常广泛。该文所研究的300 ft自升式钻井平台作业水深为300 ft,可在除挪威北海以外的世界范围海域作业,该项目由大连船舶重工自主设计,是国内首座完全具有自主知识产权的作业水深为300英尺(桁架式桩腿)的自升式钻井平台,填补了国内空白。该项目研究属国内首创,大连船舶重工紧密跟踪市场需求,通过国际合作、自主研发等手段,开展技术攻关,成功解决了平台总体设计技术研究、平台结构设计及强度分析技术研究、平台振动与噪音技术研究、电气控制技术及系统研究、"零"污染排放等关键技术难题,为集团最终形成实船订单提供了重要技术保障。

As the development of world economy and technology, petroleum has became a very important energy source, and been used more and more widely. Many petroleum companies pay more attention to the exploitation of sea petroleum, for the dwindling of limited land petroleum source. Compared with other sea petroleum exploitation equipments, self--elevating platform can be moveable, easily built, and adapted to different environment of seabed and water depth, so it is used widely around the world . The self--elevation drilling rig suitable for 300ft water depth discussed in this article is able to perform all over the world except North Sea of Norway. This rig which is designed by DSIC independently is the first rig with triangular truss type legs, 300ft water depth capacity, and fully China intellectual property, which fill up blankness in drilling rig history of China. This platform is designed successfully for the first time in China. As following market requirement, DSIC overcome on technique difficulties by means of international cooperation and independent research, solved technique problems as platform general design technique research, rig structure design and strength analysis technique research,platform vibration and noise technique research, electronic control technique＆ system research,Zero--pollution discharge etc, and provide a technique foundation for the final actual order of the corporation.
