Submarine cables are important power and signal transmission facilities that communicate between offshore and land facilities. In the laying construction of the submarine cable, an appropriate construction method is selected according to local conditions according to different marine hydrology, terrain and landform conditions, particularly water depth conditions, of the sea area where the cable is designed and routed.
The long-distance sandbar section is a sandbar section which is similar to intertidal zones and is characterized by water at high tide and exposed beach at low tide; meanwhile, the cable laying ship cannot pass through the past sandbar section by using the once high tide. For a long-distance sandbar section, the current submarine cable laying construction method comprises the following steps: selecting a cable laying ship with small draught; after the cable is loaded, the draught of the cable laying ship is smaller than the water depth of the sand bank section at high tide. In the high tide time period, towing the cable laying ship by using two anchor boats and traveling the ship along the cable design route; meanwhile, cables are buried while being paved. And in the low tide time period, the cable laying ship and the two anchor boats are in stand-by state on the beach.
The construction method of the side towing ship can effectively solve the problem of submarine cable laying construction in a long-distance sand continent section. The corresponding problems that come with this are: 1) the required draught of the anchor boat is not more than that of the cable laying ship, but the anchor boat with small draught usually has small horsepower, so that the power is insufficient when the cable laying ship is dragged, and the difficulty in selecting the anchor boat is high and is not easy to solve; 2) the cable laying ship with insufficient towing power is greatly influenced by sea conditions such as wind, ocean currents and the like, so that the track control of the cable laying ship is difficult, and the actual cable laying route deviates from the cable design route greatly.
