![]() In recent years, scholars have performed many studies on the installation of the tree, most of which consist of engineering application reports and installation process or method studies, but mechanics analyses have not been frequently reported. Therefore, in this paper, we choose installation of the tree lowered by a drill pipe (hereafter referred to as the pipe) as the research object. In addition, the cost of using drill pipes, including maintenance costs, is quite low compared with those of the riser and winch. The conventional procedure with drill pipes is still widely used because this method sharply decreases the running time. Three methods are available for installation of the tree: winch, conventional completion riser, and drill pipe. Therefore, it is necessary to analyse the motion characteristics for installation of the tree, which is important for higher safety reliability in subsea conditions. From shallow to deep water, the cost of the underwater equipment has not significantly increased, but the installation cost and installation risk have risen rapidly due to the complex combination of wave and current. With the rapid development and exploitation of offshore oil and gas from shallow to deep water regions, the subsea Xmas tree (hereafter referred to as the tree) is a key piece of equipment in the subsea production system and is widely used in deep water. ![]()
