Problems solved by technology
However, judging from the current application situation, the technical difficulty is mainly in the construction aspect. The construction cost of the complete set of impressed current cathodic protection equipment for the jacket is greater than the cost of the equipment itself, and the construction quality and reliability have a great impact on the system reliability.

The invention discloses an anchoring device for rapid tensioning installation of a tensile cable. The device comprises a tensile steel cable, a tensile cable, a jacket and a heavy lump and further comprises an anchor, wherein the anchor comprises an anchoring body, a hinge pin and a limiting piece, the anchoring body is in a U shape, an opening of the anchoring body faces downwards, the anchoringbody is fixed to the jacket, a plurality of paired limiting holes are formed in the two parallel vertical sections of the anchoring body in the length direction of the anchoring body correspondingly,the hinge pin penetrates through one of the pairs of limiting holes and forms a limiting space with the anchoring body, the limiting piece is arranged in the limiting space, a through hole is formed in the arc-shaped section of the top of the anchoring body, the tensile steel cable penetrates through the through hole and extends into the limiting space to be connected with the limiting piece, oneend of the tensile cable extends into the limiting space to be connected with the limiting piece, the other end of the tensile cable is connected with the heavy lump, and the limiting piece abuts against the hinge pin under the driving of the heavy lump. The device is suitable for field installation of a far-field type auxiliary anode, the construction difficulty of an impressed current system isreduced, and meanwhile the construction reliability is improved.
Description
technical field [0001] The invention relates to the technical field of marine engineering, in particular to an anchor device for fast tensioning and installation of tension cables. Background technique [0002] The jacket platform is currently the most widely used offshore oil platform in offshore engineering. Its basic structure (ie, the lower structure) is composed of various tubular carbon steels, and the bottom is embedded in the sea mud to provide support for the upper module of the jacket. Since seawater is a strong corrosive medium, if effective anti-corrosion measures are not taken, the steel 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] At present, the common practice in China to deal with jacket corrosion is to weld a sufficient amount of sacrificial anodes when the jacket is constructed. With the development o...
