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

Abstract

The invention discloses an offshore floating body one-cable multi-anchor mooring device capable of effectively responding to changes in seabed bottom quality and solving the problem of insufficient gripping force of mooring systems. The invention includes a main anchor cable, which is characterized in that the main anchor cable is connected to two auxiliary anchor cables through a connecting plate, and the auxiliary anchor cable is connected to an anchor or a serial anchor group, and the serial anchor group is connected through a closed socket and The swivel shackle is connected to the buffer, the buffer is connected to the triangular eye plate, and the triangular eye plate is composed of two anchor cables connected to the anchor, and the anchor is connected to the anchor cable, the buoyant cable and the buoy in turn. In the case of poor sea bottom quality, the invention can conveniently increase the number of anchors to increase the holding force to solve the problem of insufficient anchoring force. Under the premise of providing the same mooring force, the invention can effectively reduce the weight of a single anchor, and facilitate the arrangement and recovery of mooring systems.

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...

AI Technical Summary

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.
