Description

Technical Field

[0001] The utility model relates to the field of submarine cable application equipment, in particular to submarine cable laying and repairing equipment. Background Art

[0002] During the laying or maintenance and cable collection process of the submarine cable, the submarine cable needs to move from the hull to the seawater or from the seawater to the hull. There is a height difference between the hull and the seabed. Therefore, during the laying or maintenance and cable collection process of the submarine cable, the submarine cable needs to be bent. Therefore, a bend limiter is used to limit the bending degree of the submarine cable in the device to prevent the submarine cable from being damaged by excessive bending during the laying process.

[0003] However, the safe bending diameters of submarine cables of different diameters are different, and the existing bending limiters have a fixed curvature and cannot be adjusted, making them inconvenient to use. At the same time, during the navigation of a ship, the ship may deviate due to wind and waves, and it is not convenient to adjust its position immediately, which may easily cause the submarine cable to be laid crookedly.

[0004] To this end, we proposed a submarine cable laying and maintenance equipment. Utility Model Content
