  • Method for installing a tension leg platform
    Patent number: 6022174
    Abstract: In a method for installing an offshore tension leg platform, a freely floating platform structure (7) is coupled to previously mounted tension legs (1) without the use of temporary motion compensating coupling mechanisms between the upper ends of the tension legs and the platform structure. Instead, permanently installed coupling elements (5) at the ends of the tension legs (1) are used and during the transition of the platform structure (7) from freely floating condition to moored condition by means of the tension legs (1), the coupling elements (5) are allowed to impact quite heavily against the corresponding connecting means (9) on the platform structure during its wave induced movements until it is held continuously by the tension legs.
