TENDON OF A TENSION LEG PLATFORM AND ELECTRICAL CORROSION PROTECTING METHOD OF THE SAME |
摘要 |
The tendons of a tension leg platform (TLP) used for producing petroleum offshore at a depth of 400-1000 m are protected against fatigue corrosion which mainly determines the life of the tendons. The straight steel pipes (1) have an insulative, corrosion-protection coating (8) having good damage resistance. The screw couplings (2) have a sprayed aluminum layer (9) having the ends contiguous to the ends of the insulative, corrosion-protection, and a galvanic current anode (5) is electrically connected to the screw coupling (2). |
