Off land loading and unloading anchoring system and anchoring method for liquid bulk cargo carrier

Abstract

The invention relates to an offshore loading, unloading and mooring system for liquid bulk carriers as well as a mooring method, and the invention is characterized in that the mooring system consists of three sets of mooring device; the mooring device is formed by using connecting components to connect a buoy, a suspension bullback-weight, a chassis bullbacke weight and a anchoring base one by one; when in mooring, each set of mooring device connects the buoy and a carrier together by connecting components, wherein, two sets of mooring device are connected with the head of the liquid bulk carrier; another set of the mooring device is connected with the stern of the liquid bulk carrier; the three sets of mooring device are in Y-shaped arrangement; the mooring system can anchor the liquid bulk carrier in an off-shore sea area to load or unload materials; compared with the prior art, the invention has the advantages of small occupation sea area, low investment, short construction cycle, convenient operation, safety and reliability. Moreover, the invention does not take up shore-line resources, and is easy to be recovered and ruled, as well as especially suitable for the loading and unloading of the liquid bulk carriers.

Description

Technical field [0001] The invention relates to a ship mooring device, in particular to an offshore loading and unloading mooring system and mooring method for a liquid bulk carrier, which is suitable for loading and unloading liquid and bulk material cargo ships. Background technique [0002] In the prior art, there are mainly three mooring forms for loading and unloading materials on cargo ships with liquid or bulk materials: one is a single point mooring device, a mooring buoy is moored at sea by six anchor chains, and there are rotatable mooring devices on the buoy. The center of the buoy is used for the mooring arm that rotates 360 degrees and the oil transfer swivel head, and is connected with the cargo ship through the mooring arm and the bow of the cargo ship. The mooring device has the advantages of wind vane characteristics, small force, low investment, short construction period, convenient use, safety and reliability, etc., but the disadvantage is that it occupies...

AI Technical Summary

Problems solved by technology

But the disadvantage is that the mooring arrangement is not compact enough, the mooring cables are easy to wear and fatigue, and the operation of mooring and mooring is more troublesome than single-point mooring; Provide a rigid mooring body; the advantage is that the loading and unloading operations are convenient, but the disadvantage is that it is expensive, there is a greater risk of berthing and unberthing, and it occupies shoreline resources
