Description

Technical Field

[0002] In marine engineering, laying submarine cables is a critical and complex engineering task. As an important channel connecting submarine equipment with land facilities, the laying quality of submarine cables is directly related to the stability and safety of the entire marine engineering system. Traditional methods of laying submarine cables mostly use ship towing or submarine excavators and other equipment, but during the process of submarine cables entering the water, the influence of natural factors such as ocean currents, tides, wind and waves brings great challenges to the laying work.

[0003] With the increasing development and utilization of marine resources, the laying and maintenance of submarine cables (hereinafter referred to as "submarine cables") as the key transmission medium connecting offshore facilities and land networks have become particularly important. Submarine cables usually start from land and gradually enter the deep sea through the coastline. As an important channel connecting submarine equipment and land facilities, the laying quality of submarine cables is directly related to the stability and safety of the entire marine engineering system. During the laying of submarine cables, submarine cables need to complete the transition from land to underwater through water-entering guide devices.

[0004] However, due to the influence of natural factors such as tides, waves and currents, the submarine cable laying vessel is prone to shaking during the laying process, which in turn applies dynamic force to the submarine cable, causing displacement and tension changes in the submarine cable, which can easily cause excessive bending of the submarine cable and even increase the risk of the submarine cable being torn. The current guide device is a rigid structure and needs to be laid within the designed sea conditions, that is, to reduce the shaking of the submarine cable laying vessel, it is necessary to choose appropriate sea conditions and the construction window period is short.

[0005] There is no effective solution yet for the problems existing in the relevant technology, such as the submarine cable guiding device being easily shaken with the submarine cable ship, the submarine cable being easily broken, and the submarine cable laying window period being short.
