Navigating and Locating of Semi-submersible Platform Using GPS

Along with the offshore oil and gas exploration and mining in the East China Sea,our company has successfully undertook the following well yard exploration projects and drilling platform towing projects,such as Jiao-1,FuYang-1,ChunXiao-1,ChunXiao-2,ChunXiao-3,ChunXiao-4,ChunXiao-5,TianWaiTian-2,TianWaiTian-3,CanXue-2 and etc. Through implementations of these projects,we have formed a set of quite successful operating procedures,and accumulated rich experiences in such projects. In this article,we briefly introduced the GPS technology. Then we elaborated the application of the positioning instrument of GPS in the entire process of the tow positioning well for the Semi-submersible platform. And we also gave some suggestions about such a process as a reference to people concerned.
