Abstract

The invention relates to the technical field of ocean anticorrosion engineering, in particular to a jacket platform far anode type corrosion control device and a use method thereof. The jacket platform far anode type corrosion control device comprises double reference electrodes (6), an auxiliary anode (3), an anode cable (2) and a cathode cable (5), wherein the auxiliary anode (3) is far from a jacket platform (8) and arranged on the bottom of the sea, the double reference electrodes (6) are arranged on the middle lower portion of the jacket platform (8), a rectifier (1) is arranged on the top of the jacket platform (8), a potential detection device is arranged on the rectifier (1), the potential detection device is connected with the double reference electrodes (6), the double reference electrodes (6) are arranged on the middle lower portion of the jacket platform (8) and symmetrically arranged on two sides of jacket platform (8), the auxiliary anode (3) is connected with an anode of the rectifier (1) through the anode cable (2), and a cathode of the rectifier (1) is connected with the jacket platform (8) through the cathode cable (5). The jacket platform far anode type corrosion control device and the use method of jacket platform far anode type corrosion control device are simple in structure, effective in method, convenient to install, long in service life, and low in cost.

Description

technical field [0001] The invention relates to the technical field of marine anti-corrosion engineering, in particular to a remote-anode corrosion control device for a jacket platform and a method for using the same. Background technique [0002] The jacket platform is currently the most widely used offshore oil platform in offshore engineering, and generally consists of a superstructure and a foundation structure. The superstructure generally consists of upper and lower platform decks and living and production modules. The foundation structure (i.e. substructure) consists of the jacket and piles. These structures are generally steel structures. As seawater is a strong corrosive medium, if effective anti-corrosion measures are not taken, the jacket platform will suffer corrosion damage in the harsh marine environment, which will affect the life of the platform and safe production, and increase the maintenance cost of the platform. [0003] The corrosion control of the ja...
