A fixed protection device for submarine cables after going out of the submarine cable ditch

Abstract

The invention discloses a device for fixing and protecting a submarine cable after the submarine cable comes out of a submarine cable ditch to land on a platform along the pile legs of a steel-structured building on the sea. The device is suitable for various fixing and protecting places where the submarine cable coming out of the submarine cable ditch is utilized to land on the platform. A self-sinking type anchor imitating member, a connecting flange of 90 DEG and an anti-corrosion metal hose are used for protecting the bared submarine cable in a fully-sealed manner through connecting bolts after the submarine cable comes out of the submarine cable ditch and then is placed between the fixing clamps of metal submarine cable protecting pipes of the pile legs of the platform, so that the service life of the submarine cable is prolonged greatly, and the reliability and the safety of power electricity application in offshore oil exploration and development are ensured.

Description

technical field [0001] The patent of the invention relates to the field of fixed protection of submarine cables. Specifically, it is a device for fixing and protecting submarine cables when a submarine cable exits from a submarine cable ditch and lands on a platform with pile legs of a steel structure on the coast. It is suitable for various types of submarine cables using submarine cables A fixed protective place when landing on the platform behind the ditch. Background technique [0002] Most of the power used in offshore oil exploration and development is transmitted to various oil exploration platforms or operating platforms through land substations and submarine cables. When laying submarine cables, first lead the submarine cable from the land cable trench to the seawall, and then do a good job of protecting and insulating the place where the submarine cable enters the sea. The cable laying is buried in the excavated submarine cable trench. When the submarine cable is ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the patent of the present invention is to provide a fixed protection device for the submarine cable after going out of the submarine cable ditch. After using the fixing device, it fundamentally solves the problem of the unprotected suspension of the section of the submarine cable between the early exit of the submarine cable ditch and the fixing clips of the platform legs. At the same time, it also solved the problem that the submarine cable was not firmly fixed at the outlet of the trench with sandbag ballast after the submarine cable exited the trench in advance. Secondly, it also fundamentally solved the fixing clip when the submarine cable was fixed to the platform legs. The problem of fraying submarine cables

[0006] The patent of the present invention has the following functions and positive effects: the device can realize the full sealing protection and force transmission of the exposed submarine cable between the submarine cable ditch and the platform leg fixing clip, and fundamentally solve the problem of this section of the seabed. The problem that the cable is suspended in the air without protection is also solved. At the same time, it also solves the problem that the submarine cable is not firm at the place where the submarine cable exits the trench with sandbag ballast in advance, and the fixing clip wears the submarine cable when the submarine cable is fixed to the platform legs. The problem has greatly improved the service life of submarine cables and ensured the reliability and safety of power consumption in offshore oil exploration and development.
