Problems solved by technology

Therefore, the installation method of the above-mentioned protective tube has low installation efficiency and accuracy; and has many disadvantages such as high cost, divers need to wait for the flat tide time of the working water area, etc., so in the installation method after the cable protective tube, a cable protective tube is created. Handy tool for post-installation becomes imperative

Embodiment Construction

[0024] like figure 1 — image 3 As shown, the present invention includes: a sleeve connected with one or more cable protection pipes 3 respectively, and a riser connected with the sleeve by welding; wherein, the connection between the sleeve and the plurality of cable protection pipes 3 is performed on land It is pre-set as a whole; the sleeve is provided with a sleeve ring 1 at a certain distance, and a support structure 2 is provided on the side opposite to the riser by welding. The function of the support structure 2 is to make the whole structure form a complete closed loop.

[0025] The distance between the above-mentioned sleeve rings 1 on the sleeve is 3 to 5 meters. If the water depth is shallow, the distance between the sleeve rings 1 can be flexibly adjusted. The direction close to the seabed is the downward direction) and upward (the direction of the sea surface is the upward direction) to realize the gradual transition of ovality from small to large. The cylinde...

Abstract

The invention discloses a single-pile multi-cable-protection-tube installation sleeve device, and the device comprises a sleeve connected with a plurality of cable protection tubes, and a vertical tube connected with the sleeve. The connection between the sleeve and the plurality of cable protection tubes is completed on the ground in an integrated embedded manner. Sleeve rings are disposed on the sleeve at certain intervals, and a side surface, opposite to the vertical tube, is provided with a support structure which enables the whole structure to form a complete closed loop. The device not only can quickly and conveniently install one or more cable protection tubes at a time, can greatly reduce the offshore construction cost of a single cable protection tube, and improve the construction efficiency and installation precision; but the device can reduce the cost of a construction side in the offshore installation of the cable protection tubes by 2 million yuan or more while reducing the offshore construction cycle and oil field exploitation cost.

Description

technical field [0001] The invention relates to a cable protection pipe, in particular to a single-pile type multi-cable protection pipe installation sleeve device used in marine engineering. It belongs to the field of offshore petroleum engineering. Background technique [0002] There are many occasions in marine engineering where submarine cables need to be laid, which can be hundreds or thousands of kilometers long, and the short cables may be only tens of meters. The cables in the water generally need to be protected by cable conduits to climb from the seabed into the offshore structure. Taking only offshore wind power generation as an example, at present, in wind power development projects at home and abroad, monopile structures are mostly used as the foundation of offshore wind turbines and the monopile foundation of offshore power generation booster stations. According to the analysis, monopile foundations account for 76.3% of the global offshore wind farms that hav...
