The residual buoyancy and the pretension balance. Semi-compliant semi-rigid： The pretension causes the tension leg to be tense in tension, so that the motion (rolling, pitching, and hanging) of the platform plane is smaller and is similar to rigidity. 4 5 Working characteristics Good motor performance Large environmental loads can be balanced by inertial forces, without the need to balance them through structural internal forces. Higher security The natural frequency of motion in the plane of the platform is lower than the wave frequency, while the natural frequency of motion outside the plane is higher than the wave frequency. The water depth is 300-1500 meters The tension leg platform usually separates the main body of the platform from the upper body and then makes a joint at sea. The entire installation of SeaStar TLP can be divided into four separate phases. 6 Build and install the process Stage 1: installation of seabed foundation (2 ~ 5 days). Stage 2: tension leg installation (2 ~ 5 days). Stage 3: Installation of the main body of the platform (1 day). Stage 4: installation of the upper body of the platform (1 day). According to the general structure classification Can be divided into two broad categories, the first generation of tension leg platform and the second generation of tension leg platform; According to different classification of tree of oil tree It can be divided into two categories: wet tree platform and dry tree platform; Categorize functions and applications It can
