MOORING SYSTEM OF TENSION LEG PLATFORM

摘要

The present invention relates to a mooring system of a tension leg platform (TLP) and, more specifically, a mooring system of a TLP which is provided to have risers installed inside a tendon, thereby preventing the risers from colliding with each other or being damaged by fatigue due to an external force such as tidal current and wind; to reduce vortex induced vibration (VIV) generated around the risers by the tidal current, thereby extending the fatigue life of the riser; and to significantly reduce hours for installing the riser, thereby saving hours and expenses required for marine construction. The mooring system of a TLP according to the present invention comprises: a tendon which is connected to the hull of the TLP and fixed on the seabed and which has a hollow therein; and a riser which is installed inside the hollow of the tendon and which includes a riser providing a fluid passage for drilling.
