差分定位技术在移动式钻井平台拖航与就位作业中的应用

Application of Differential Positioning Technology in Towing and Positioning Operation Offshore Platform

移动式平台是海洋油气资源开发的重要支撑平台,在中浅水海域以自升式平台为主,深水海域以半潜式平台为主,这类平台在不同地点作业时需要船舶辅助拖航,在设计位置就位时必须依靠高精度的定位测量技术保障准确就位。通过介绍移动式平台在海上进行拖航与就位作业的主要方式、特点和要求,分析了不同海洋定位测量方法的技术特点,重点介绍了星站差分定位技术在移动式平台拖航与就位作业中的应用情况,对开展此类定位工作具有一定的参考意义。

Offshore platform is an important supporting platform for the development of marine oil and gas resources.Jackup rig is suitable for shallow water,and Semi-submersible rig is suitable for middle and deep water.These platforms can work in different location with the aid of towed vessels.Prices positioning technology is most important for towing and positioning operation of offshore platforms.The characteristics and requirements of towing and positioning operation of offshore platform are introduced and the difference of different ocean position measurement methods is analyzed.Satellite station differential positioning method is used to measure the position of offshore platform during towing and positioning operation.
