Abstract

The technical problem to be solved by the present invention is as follows: so far, there is no method for fully automatic and real-time realization of multi-vessel positioning during the construction of submarine cables in ultra-shallow water. In order to solve the above-mentioned technical problems, the technical solution of the present invention is to provide a method for construction and positioning of submarine cables in ultra-shallow water combined with multi-vessel. In the present invention, DGPS is used for real-time differential positioning, which improves the accuracy, and the accuracy in the continental shelf area is less than 1 m; the present invention uses the ultra-long-range wireless local area network system to network multiple ships, ensuring that there is no mobile signal coverage on the sea. Ships can communicate reliably; the software designed in the present invention can display multiple moving objects on the same interface of the positioning software, the positioning and construction operations of multiple ships are relatively independent, and the barge can effectively monitor the positioning of the anchored boat and issue instructions.

Description

technical field [0001] The invention relates to a technology for joint construction of submarine cables by multiple ships in ultra-shallow water, and belongs to the technical field of submarine optical cable construction methods. Background technique [0002] Traditional submarine cable installations are usually operated independently by a single cable construction vessel. In the ultra-shallow water operating environment, the traditional submarine cable construction vessel cannot enter the ultra-shallow water area for construction due to the limitation of the ship's draft. Therefore, the submarine cable construction in ultra-shallow water is usually completed by a barge with a shallow draft. [0003] Barges usually do not have self-propelled power, so in order to accurately locate the cable routing and not damage the cables during construction, the barge needs to be assisted by anchoring boats to achieve precise positioning and movement of the barge on the sea. [0004] The...
