Abstract:
In order to promote the local production of subsea vertical tree, a study is launched based on the sea experiment of subsea vertical tree prototype. Through the analysis of the structural features of subsea vertical tree and its installation methods as well as the combination with existing related standards and researches at home and abroad, the requirements are put forward which are needed in the installation and testing process, the installation schemes of sea experiment are designed, the installation procedure is formulated, while the displacement and stress condition of drill pipe are analyzed during the installation process with Drill Pipe Installation Method. The study result will provide a reference for the sea experiment operation of domestic subsea vertical tree and related subsea production equipmen
