Adaptive mooring device in shallow coastal waters

Abstract

An adaptive mooring device in shallow coastal waters comprises a ship, wherein one side of the ship is provided with buoys which are arranged separately, two ends of the buoy are fixedly connected with the ship through a mooring line, the outer end face of the buoy is spaced apart from the outer side face of the ship, the bottom of the buoy is connected with an upper pile, the bottom of the upperpile is connected with a lower pile through a universal rotating ball hinge, and the lower pile is inserted into a subsea foundation. The ship is anchored on the buoy with variable cross-section by the anchor chain line, the buoy transmits the hydrodynamic load and the ship impact force to the submarine foundation through the lower pile, and the horizontal force is released by the universal rotating spherical hinge, so as to reduce the requirement of the submarine foundation. The device reduces the cumbersome anchoring and retracting process of traditional mooring, greatly reduces the mooringradius of ships, improves the utilization of anchorage, and has very high safety and reliability.

Description

technical field [0001] The invention relates to the technical field of marine engineering systems and equipment, in particular to an adaptive mooring device for nearshore shallow water areas. Background technique [0002] The length of my country's coastline has reached 18,000 kilometers. On such a long coastline, there are five port groups in the Bohai Sea, the Yangtze River Delta, the southeast coast, the Pearl River Delta and the southwest coast. With the acceleration of port construction and development, the berths of the port waters The number of ships and the number of ships entering and leaving the port are also increasing year by year, which has brought about further aggravation of congestion in some waters and anchorages, and there has been a long-term phenomenon of illegal anchoring. At present, the calculation of the anchorage area is mainly based on the "Code for General Layout Design of Seaports", which is related to factors such as the length of the ship, water ...

AI Technical Summary

Problems solved by technology

[0003] 1) The efficiency of anchoring and anchoring is average, requiring a whole set of cumbersome operating procedures;

[0004] 2) The mooring radius of the ship is relatively large, which seriously affects the applicable anchorage area, and the utilization rate of the anchorage in the port area is poor;
