Problems solved by technology

However, the intertidal zone is characterized by high tide floodplain, low tide dewbeach, and water depth of only 3-5 meters during high tide, which determines that the conventional offshore submarine cable construction technology is not suitable for the intertidal zone

Abstract

The invention discloses an intertidal belt submarine cable paving method which comprises the following steps: (1) at high tidal level, drawing a shallow draught flat-bottomed barge with cable to a starting position of circuit in which submarine cable is needed to be paved; (2) placing a cable guiding cage located at barge tail between seawater and beach face; (3) releasing the submarine cable to the beach face from the cable guiding cage through a guiding and twisting rack on the barge; and (4) burying the submarine cable to needed depth through a paving device. By the intertidal belt submarine cable paving method, the problem of intertidal belt submarine cable paving is solved, construction cost is greatly lowered, and submarine cable construction process is simultaneously optimized.

Description

technical field [0001] The invention relates to the marine engineering industry of the offshore wind power industry, in particular to a method for laying intertidal submarine cables. Background technique [0002] The intertidal zone is the area between the high and low tide levels of the spring tide, which is submerged and exposed as the tide rises and falls. According to preliminary estimates, the annual average wind speed in the intertidal zone can reach 6-7 m / s, so there is available wind energy in the intertidal zone. [0003] The wind turbines in the wind farm in the intertidal zone need to be connected by submarine cables (submarine cables), and the buried depth is more than 2 meters. However, the intertidal zone is characterized by high tide floodplain, low tide dew beach, and water depth of only 3-5 meters during high tide, which determines that the conventional offshore submarine cable construction technology is not suitable for the intertidal zone. [0004] There...
