Floating body one-cable multi-anchor anchoring and mooring device at sea

Abstract

The invention discloses an anchoring device of a float body with a function of one cable with multiply anchors on the sea, which can effectively deal with the changes of the sea bottom characteristics and solve the problem of short grapping force of the anchor. The invention essentially includes a main cable and is characterized in that the main anchor cable is connected with the two side anchor cables through a connection plate. The side anchor cable connects the anchor or a tandem anchor group which is connected with a buffer through a closed funicular joint and a circle-turning shackle. The buffer connects a triangle ocular shield comprising anchors connected through two anchor cables. The anchor connects the anchor, floating cable and float in sequence. When the sea bottom characteristics are poor, the invention can easily increase the amount of the anchor in order to increase the grapping force for solving the problem of short grapping force of the anchor. Under the precondition of providing the same anchoring force, anchoring device of a float body can effectively reduce the weight of a single anchor and facilitate the distribution and recycle of the anchor system.

Description

technical field [0001] The invention relates to the technical field of mooring and positioning of floating bodies on the sea, and more specifically, relates to a mooring system with one cable and multiple anchors. Background technique [0002] Mooring positioning is a very important technology in the positioning technology of offshore floating bodies. Usually there is only one anchor arranged on one mooring cable, but when the bottom quality of the seabed is unknown or the estimated mooring force is too small, there will be insufficient mooring force. The mooring system can provide sufficient mooring force, and two or more anchors can be arranged on one mooring cable, which also helps to reduce the water area covered by the mooring system, and can realize mooring positioning in a limited water area. In the US Navy's sea rescue operations, trestle wharf systems and mooring systems of foreign offshore drilling platforms, the combined use of one cable and multiple anchors is a...

Problems solved by technology

[0003] The technical problem to be solved by the invention is to overcome the deficiencies of the combined anchors in the prior art, and provide an offshore floating body-cable multi-anchor mooring device that can effectively deal with changes in the bottom of the seabed and solve the problem of insufficient anchoring force.
