Description
Technical field
The utility model is related to a kind of mooring systems, more particularly, to a kind of single-point anchor for auxiliary ship station dynamic positioning
Pool system.
Background technology
With deepening continuously for ocean development, people are gradually transitioned into deep-sea to the detection of Yu Haiyang by shallow sea, to ocean
Exploitation and detection need to use dynamic positioning ship, and the positioning of these dynamic positioning ships rely primarily on install thereon it is dynamic
Power positioning system, but traditional dynamic positioning system can only realize large-scale positioning so that positioning is unstable, therefore someone
It proposes to combine mooring system to carry out auxiliary positioning on the basis of original dynamic positioning system.Single point mooring system is distinctive because of its
Advantage and be used widely, common single point mooring system is normally only by a mooring hawser mooring at present, sea situation more
When severe, the both ends of mooring hawser are highly prone to more drastically fierce shock loading, so that mooring hawser both ends
Mooring tension moment becomes larger, while the phenomenon that will produce stress concentration, this makes single point mooring's structure be easy in extreme sea condition
Lower generation bottom end system fixing structure fracture, and then the phenomena of drag of anchor occurs, or the top of mooring hawser can be made to be broken suddenly.No matter
Which kind of above-mentioned situation can all cause the safety of offshore construction more serious influence.
Invention content
It is good the technical problem to be solved by the utility model is to provide a kind of simple in structure, bearing capacity and that stablizes is used for
The single point mooring system of auxiliary ship station dynamic positioning.
Technical solution is used by the utility model solves above-mentioned technical problem：
A kind of single point mooring system for auxiliary ship station dynamic positioning, including be equipped with dynamic positioning system ship,
First mooring hawser, the second mooring hawser, floating drum and pulley assembly, the pulley assembly include pulley and for installing pulley
Pulley mounting base, the pulley mounting base is fixed on seabed, and the pulley is installed in rotation on the pulley peace
It fills on seat, it is anchor point that the stem of the ship, which is provided with, and the first end system of first mooring hawser, which is located at, described is
Anchor point, the second end of first mooring hawser are connected to one end of the floating drum, and the of second mooring hawser
It is anchor point that one end system, which is located at described, the second end of second mooring hawser pass through track on the pulley with it is described
The other end of floating drum be connected, the floating drum swims in sea.
The length of second mooring hawser is more than the length of first mooring hawser.The length of second mooring hawser
Length of the degree more than the first mooring hawser, it can be ensured that whole system is normal and stablizes use.
The bottom of the pulley mounting base is scheduled on seabed by submarine anchoring.The fixed form, simple in structure, installation side
Just and reliably.
Compared with prior art, the utility model has the advantage of：Whole system is by being arranged underwater pulley assembly
It matches with the floating drum for floating on waterborne, is carried with the rotation of pulley and the heave of floating drum to adjust the impact under buffering wave bat surge
The increase suddenly or reduction of the mooring tension born on mooring hawser caused by lotus, while the presence of pulley also changes second
The direction of transfer of tension on mooring hawser so that the flexibility of the second mooring hawser is not fully exerted, and is promoted to a certain extent
The flexibility of system reduces the rigidity of system, and then improves the security performance of system at runtime, simple in structure, carrying energy
Power is good and stabilization safe to use；Pulley plays a part of changing Impact direction, shock absorbing load in the entire system.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model middle pulley component；
Fig. 3 is the direction of motion schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As shown in Figure 1 to Figure 3, a kind of single point mooring system for auxiliary ship station dynamic positioning, including installation are dynamic
The ship 1 of positioning system, the first mooring hawser 2, the second mooring hawser 3, floating drum 8 and pulley assembly 4, the pulley assembly 4
Pulley mounting base 42 including pulley 41 and for installing pulley 41, pulley mounting base 42 are fixed on seabed 6, and pulley 41 is rotatable
Ground is mounted in pulley mounting base 42, and it is anchor point A that the stem of ship 1, which is provided with, and the first end system of the first mooring hawser 2, which is located at, is
The second end of anchor point A, the first mooring hawser 2 are connected to one end of floating drum 8, and it is anchor that the first end system of the second mooring hawser 3, which is located at,
The second end of point A, the second mooring hawser 3 pass through the track 411 on pulley 41 to be connected with the other end of floating drum 8, and floating drum 8 floats
On sea 7.
In this particular embodiment, the length of the second mooring hawser 3 is more than the length of the first mooring hawser 2.Second mooring
The length of cable 3 is more than the length of the first mooring hawser 2, it can be ensured that whole system is normal and stablizes use.
In this particular embodiment, the bottom of pulley mounting base 42 is fixed on seabed 6 by seabed anchor 5.The fixed form,
It is simple in structure, it is easy for installation and reliable.
The single point mooring system is expressively more notable for the effect of dynamic positioning ship 1, due to dynamic positioning ship 1
It will not occur to be translatable or rotate on a large scale very much under the compound action of each propeller, 1 redundancy of ship caused by extraneous load
The excessive phenomenon of hawser tension caused by displacement can well be eliminated by the single point mooring system.Therefore, for
For the ship 1 of dynamic positioning, this is a kind of good mode for reducing hawser tension.
Under the effect of extraneous wave loadings, the heave movement of dynamic positioning ship 1 can be caused, and then can be made to mooring hawser
At stretching, this underwater length for allowing for mooring hawser changes at any time, and this variation drastically is turned by pulley 41
Change is transmitted on floating drum 8, due to the stickiness and damping action of water so that the heave movement of floating drum 8 can relatively slowly, and then pass through
Heave movement of the floating drum 8 on sea 7 makes this shock loading obtain slowly effectively discharging relatively.
