Description

Technical Field

[0002] Offshore wind power has been developed for many years. In the early stages of wind farm development, some submarine cable accessories had certain defects in their design, and the sea conditions in some sea areas were relatively complex, which led to the slippage of some submarine cable center positioning devices. Therefore, a submarine cable protection device is needed to protect the submarine cable whose center positioning device slips.

[0003] At present, the submarine cable protection device mainly eliminates the slip distance by pulling the submarine cable to the platform again. This method requires a certain pulling margin for the submarine cable, and requires the removal of the original submarine cable fixing device and the purchase of additional submarine cable fixing devices. However, because the submarine cable was laid at an early time, the pulling margin of the submarine cable cannot be determined, so it is necessary to protect the submarine cable without pulling the submarine cable.
