Fixing and protecting device for submarine cable coming out of 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 cables from the land cable trench to the seawall, and then do a good job of protecting and insulating the submarine cables entering the sea; then use the trench boring machine for the submarine cable laying ship to excavate the submarine cable trench...

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 it goes 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 advance out of the submarine cable ditch and the fixing clips of the platform legs. The problem

At the same time, it also solves the problem that the submarine cable is not firm when the submarine cable exits the trench in advance and is fixed with sandbag ballast.

Secondly, it also fundamentally solves the problem that the fixing clip wears the submarine cable when the submarine cable is fixed to the platform legs.
