High-quality and efficient submarine cable laying system and method

Abstract

The invention discloses a high-quality and efficient submarine cable laying system. The system comprises a construction ship, a gantry crane, a submarine cable untwisting disc, a cable guiding device,a cable distributing machine and a submarine cable burying machine, wherein the gantry crane, the submarine cable untwisting disc and the cable guiding device are all arranged on the construction ship, the submarine cable untwisting disc is arranged on the left side of the cable guiding device, the cable distributing machine is arranged on the right side of the cable guiding device, the gantry crane is arranged on the right side of the cable distributing machine, and the submarine cable burying machine is arranged in the sea bottom through the gantry crane. According to the integrated hoisting mode during submarine cable loading, a whole submarine cable reel which is rotated and wound is hoisted to a rotary base, a submarine cable is untwisted during construction through the submarine cable untwisting disc, quick reversing and speed change can be achieved, the speed adjusting range is wide, and the equipment safety and reliability are good; the submarine cable enters the underwater cable distributing machine and is constructed after being untwisted through the submarine cable untwisting disc, the transmission ratio is stable, and the submarine cable is buried under the effect of the submarine cable burying machine.

Description

technical field [0001] The invention relates to the technical field of submarine cable construction, in particular to a high-quality and efficient submarine cable laying system and a laying method thereof. Background technique [0002] With the development of my country's offshore wind power, my country will enter the stage of large-scale development of offshore wind power, and it is necessary to develop and construct offshore wind farms with far offshore distances (greater than 12 km) and large capacities (200-400 MW). It is necessary to set up an offshore booster station. The establishment of an offshore booster station is inseparable from the laying of submarine cables. As we all know, the laying of submarine cables is a long-distance project. The cable construction process cannot be interrupted or stopped, and the entire laying process cannot be disturbed by foreign ships. To ensure the safe construction of submarine cables, there can be no mistakes in the whole process. T...

Problems solved by technology

[0002] With the development of offshore wind power in China, my country will enter a period of large-scale development of offshore wind power. It is necessary to develop and construct offshore wind farms with long offshore distances (greater than 12 km) and large capacity (200-400 MW). It is necessary to set up an offshore booster station. The establishment of an offshore booster station is inseparable from the laying of submarine cables. As we all know, the laying of submarine cables is a long-distance project. The construction process of the cable cannot be interrupted or stopped, and the entire laying process cannot be disturbed by foreign ships. To ensure the safe construction of the submarine cable, there must be no mistakes in the entire process. The construction period is long and consumes a lot of manpower and material resources. The completion of the laying of the submarine cable will undoubtedly have a great impact on the construction of the entire booster station
