Abstract:
PURPOSE: A TLP-type floating member and a method of replacing the tendon thereof are provided to reduce the installation and maintenance cost of a tendon since a working period of time can be shortened. CONSTITUTION: A method of replacing the tendon of a TLP-type floating member(100) is as follows. Tension control units are provided to be corresponded to each of tendons of the floating member. If there is a need for a tendon to be replaced, the tendon is replaced with other tendon. Before replacing, the tension of that tendon to be replaced is reduced using a corresponding tension control unit. Before reducing the tension of that tendon, a candidate tendon is arranged between the floating member and a foundation. After replacing that tendon, the candidate tendon is removed.

Abstract:
The present invention relates to a flexible riser system and a method for adjusting the length of a flexible riser using the same. Provided are a flexible riser system and a method for adjusting the length of a flexible riser using the same, which can properly control the length of a riser even in accord with the movements of a floating body position. Also, the invention can stably maintain the arranged state of the riser, by coupling the riser connected from the floating body to an upper end part of an oil well and an additional length adjustment unit in the middle part, and by controlling the length of the riser through the length adjustment unit, therefore easily adjusting the length and installment. Because the structure simply uses a winding reel type for the length adjustment unit, the structure can can adjust to a wide variety of arrangement shapes, overcoming the limitation of other inventions with a similar purpose.
