[0002] A mobile offshore platform is an offshore platform equipped with drilling equipment and capable of moving from one well to another. It is mainly used for offshore oil drilling and production, and also supports various marine engineering and other offshore activities. The mobile offshore platform has its own buoyancy structure and can be transported and moved at sea by tugboats. Some are also equipped with power equipment and can propel themselves. When working, they must use piles, anchors or mooring systems and dynamic positioning systems to be fixed in a specific position for a certain period of time to complete the required tasks. Among them, the wire rope used in the anchoring positioning of the mobile offshore platform plays a key role. It is used to connect the platform and the anchor together to ensure the stable positioning of the platform.

[0003] In the current existing technology, the outer surface of the anchoring and positioning steel wire ropes for mobile offshore platforms needs to be coated with an anti-corrosion coating to reduce the corrosion of the rope core of the anti-bending steel wire rope by seawater, thereby increasing the service life of the anti-bending steel wire rope. However, when the anchoring and positioning steel wire ropes for mobile offshore platforms are retracted and released, the coating on the anti-bending steel wire ropes will be damaged, causing seawater to penetrate into the steel wire ropes and corrode the rope core. Therefore, an anti-bending steel wire rope for anchoring and positioning of mobile offshore platforms is proposed to solve the above problem. Utility Model Content

[0007] Furthermore, the steel wire wrapping layer is a steel wire sleeve formed by winding a plurality of steel wires, and the steel wire sleeve is fixedly installed on the outer surface of the steel wire rope core.

[0008] Furthermore, the waterproof sleeve is an anti-corrosion rubber sleeve, and the anti-corrosion rubber sleeve is fixedly installed on the outer surface of the steel wire sleeve.

[0010] Furthermore, the rubber float is a red rubber ball.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The anti-bending steel wire rope for anchoring and positioning of a mobile offshore platform is provided with a waterproof sleeve and a protective layer, so that the waterproof sleeve composed of an anti-corrosion rubber sleeve is used to wrap the steel wire sheath and the steel wire rope core, thereby preventing seawater from penetrating into the steel wire sheath and the inside of the steel wire rope core to cause corrosion.
