Submarine cable connection operation device and operation method thereof

Abstract

The invention discloses a submarine cable connection operation device and an operation method thereof and relates to the technical field of submarine cable maintenance operation. A submarine cable maintenance ship is prone to secondary damage when a submarine cable is pulled into water. The submarine cable connection operation device comprises a cable guiding device fixedly connected with a hull,a connecting room and a cable traction winch. The cable guiding device comprises water outlet guide roller sets, a locking guide roller set, a horizontal guide roller set, a U-shaped guide roller setand a guide rail, wherein the protruding outboard portions of the water outlet guide roller sets are arc-shaped in the transverse direction and the vertical direction; the two water outlet guide roller sets are installed on the same side of a ship board; the locking guide roller set is provided with a safety locking device for fixing a cable. After cable connection is completed, the U-shaped guideroller set can slide to a gunwale along a guide rail, and the U-shaped guide roller set is hoisted through a hoisting device to enter water so as to downward release the cable. Bending damage occurring when the cable goes into or out of water or is dragged can be prevented, safe and reliable recovery, connection and downward release of the submarine cable can be effectively guaranteed, and secondary damage can be prevented.

Description

technical field [0001] The invention relates to the technical field of submarine cable maintenance operations, in particular to a submarine cable splicing operation device and an operation method thereof. Background technique [0002] With the rapid development of the coastal economy, the sharp increase in the demand for power supply on islands, and the increase in the construction scale of offshore platforms and offshore wind farms, submarine power cables have been widely used, and submarine power cables have become an important source of energy support for marine development activities. At present, the submarine cable lines in operation across the country are as long as 100,000 kilometers. However, with the laying of a large number of submarine cables, due to inevitable natural aging and human factors, submarine cable failures and damage accidents occur frequently, which requires submarine cable maintenance ships. The submarine cable connection device is the core equipmen...
