Description
Technical field
The present invention relates to a kind of single point mooring systems, have caisson type submarine anchoring device more specifically to one kind
Single point mooring system.
Background technique
Single point mooring system mainly includes cylinder and is fixed on the rotatable turntable above cylinder, crude oil by bearing
From land, oil depot is delivered to oil tanker (can also be reverse), and the mooring of oil tanker mooring line is sent to single-point system by hose in turntable, crude oil
In pool system, then land is sent to by seabed manifold；Because turntable can be rotated, so that oil tanker can be realized in any direction is
Pool, and single point mooring system, without building in harbour, freedom degree is big, therefore is the main path of extra large land oil transportation；
There is critically important meaning to the limitation of the offset distance of entire single point mooring's Transmission system.If offset distance is too
Greatly, it is excessive and cause hose fracture that oil leak event then occurs to will lead to hose stress, pollution of marine environment brings about great losses
With influence.Therefore, what single point mooring system need to be fixed by the six roots of sensation anchor chain and sea bed that are fixed on cylinder body bottom, and traditional consolidate
Determining mode is that anchor chain is connected to anchoring pile, and anchoring pile is squeezed into sea bed bottom by way of piling and realizes fixation, but this sea bed
Piling work cost is huge and operation is inconvenient.
