The invention discloses a method for installing an integrated device for impressed current cathodic protection of a remote jacket, comprising: arranging the installation line, releasing the anode dynamic cable into the water; Going up the platform; connecting the supporting steel cable and the reference electrode cable; air diving operation, lowering the supporting steel cable, and keeping in sync with the lowering action of the anode dynamic cable, using ROV underwater real-time observation; after the fixed sinker is connected to the supporting steel cable Put it into the water, place it in place, and fix it with stakes; connect the anode dynamic cable to the auxiliary anode frame and then cure and seal it, hoist it into the water, put it in place, and at the same time, ROV observes in real time and moves the ship to cooperate. The installation method of the present invention can ensure the continuity and safety of the offshore installation of the integrated device, can realize the safe release and effective control of the anode dynamic cable, and can ensure that each equipment and components do not interfere with each other during the installation process and can be carried out step by step as a whole Underwater installation.
Description
technical field [0001] The invention relates to the technical field of offshore oil jacket equipment, in particular to a method for installing a remote jacket impressed current cathodic protection integrated device. Background technique [0002] The remote jacket impressed current cathodic protection integrated device is composed of anode dynamic cable, reference electrode cable, supporting steel cable, auxiliary anode frame, fixed sinker, current stabilizer and other parts. It is a highly integrated integrated system. Therefore, it also poses great challenges and difficulties to offshore installation. [0003] The existing installation technology cannot guarantee the continuity and safety of offshore installation, cannot realize the safe release and effective control of the anode main cable, and cannot guarantee that various equipment and components will not interfere with each other during the installation process and can be gradually installed as a whole. Next install. ...
