Description

Mooring system

Technical Field

The present invention relates to the field of offshore mooring systems, and more particularly to a mooring system.

Background

Marine buoys are typically secured to designated locations in the sea by buoy mooring devices. The traditional buoy mooring device is mainly connected with a buoy and an iron anchor through a steel anchor chain, and then the position of the buoy is fixed. However, because the steel anchor chain has high cost and is easy to sink into the sea bottom after the fixation is released, the steel anchor chain is difficult to recover, and a mooring device combining a part of the anchor chain and a part of the ropes is generally adopted for fixation.

However, the mooring device combining the existing anchor chain and the rope is generally fixed by adopting an S-shaped connection mode, namely, the first end of the anchor chain is connected with a buoy, and the second end of the anchor chain is vertical to the sea water due to gravity; the first end of the rope is connected with the second end of the anchor chain, and the other end of the rope is connected with a submarine iron anchor; however, in order to quickly find the position of the rope during secondary use, a floating ball is connected to the middle area of the rope, so that the position of the rope can be found through the floating ball. The floating ball pulls the middle area of the rope to the sea surface, so that the rope is distributed in an S shape in the sea. When the arrangement mode is used in deep sea, on one hand, the actually required length of the rope is far beyond the distance between the anchor chain and the iron anchor, so that the prefabricated length of the rope does not meet the actually required length requirement, and the cost of the rope is high. More importantly, the position of the floating ball is arranged in the middle area of the rope, so that the distance between the position of the floating ball and the first end of the rope is long, and the specific position of the first end of the rope is difficult to find during secondary use, so that inconvenience in use is caused. And, because the floater is to the pulling force effect of back end in the rope, can lead to the earth-grasping power of iron anchor not firm enough, the wearing and tearing of rope are also great, short service life.
