Problems solved by technology

Among them, the auxiliary anode and reference electrode are all integrated on the composite cable, and placed near the predetermined underwater protection structure through the composite cable, and the composite cable is stretched by the tension system on the upper part of the platform and the gravity foundation placed on the seabed; The entire process of the cable from hoisting on the ship to the installation of the lower cable is extremely complicated, and the requirements for the connection and cooperation of each link are very high. It is difficult to control and can easily cause installation failure. Therefore, a safe and reliable tensioning system and its installation The significance of the method is particularly important

Abstract

The invention discloses a marine tensioned anode system and an installation method thereof. The system comprises a tensioning platform, combined cable tensioners, combined cables integrated with auxiliary anodes and reference electrodes, and gravity type foundations; the combined cable tensioners are mounted on the tensioning platform, the tensioners provide tensioning force for the upper ends ofthe combined cables, the lower ends of the combined cables are sunken to a seabed along with the gravity type foundations, moreover, the gravity type foundations provide anchorage points for the lowerends, and the combined cables integrated with the auxiliary anodes and the reference electrodes are a main part of the system. The system is simple in structure and is relatively convenient to install and transport. Meanwhile, the invention also discloses the installation method of the system. The method can be used for safely and reliably installing the marine tensioned anode system on a marineplatform. The installation method mainly includes: (1) hoisting of the combined cables and the gravity type foundations onto the installation platform; (2) submarine assembly of the gravity type foundations; (3) installation of the combined cables; (4) tension adjustment and locking fixation of the combined cables.

Description

technical field [0001] The invention belongs to the technical field of offshore platform engineering equipment, and in particular relates to an offshore tensile anode system and an installation method thereof. Background technique [0002] The tensile anode impressed current cathodic protection system is applied in the field of anti-corrosion of marine underwater structures. Among them, the auxiliary anode and reference electrode are all integrated on the composite cable, and placed near the predetermined underwater protection structure through the composite cable, and the composite cable is stretched by the tension system on the upper part of the platform and the gravity foundation placed on the seabed; The entire process of the cable from hoisting on the ship to the installation of the lower cable is extremely complicated, and the requirements for the connection and cooperation of each link are very high. It is difficult to control and can easily cause installation failure...
