Abstract
A kind of pier mooring method of tension leg platform (TLP), using following mooring step：One：Further the size of device according to the column spacing of tension leg platform (TLP) and tension force muscle, completes the design of barge and prefabricated；Two：According to the arrangement of bollard on harbour, corresponding several anchor points are set on barge；Three：Fixed along the length direction of barge in the both sides of barge and lean on ball；Four：Anchor point is fixed in the bollard of wharf apron；Five：Tension leg platform (TLP) is drawn to barge, and makes to be in close contact by the column of ball and tension leg platform (TLP)；Six：Tension leg platform (TLP) is fixed in bollard, and fastened；Seven：By the anchor point set on barge, will be connected between barge and tension leg platform (TLP).The present invention can not only by tension leg platform (TLP) mooring on harbour, solve tension leg platform (TLP) mooring stability and easily with harbour collision problem；Moreover, also assures that the safe distance between tension force muscle take-up device and harbour, substantially increase pier mooring process stablizes emerging and security.
Description
Technical field
The present invention relates to a kind of pier mooring method of the anchoring method of floating platform, more particularly to tension leg platform (TLP), category
Yu Haiyang petroleum works field.
Background technology
Tension leg platform (TLP) has obtained more and more extensive application as a kind of typical deepwater oil-gas development platform.Semi-submersible type
Platform is similar with tension leg platform (TLP), but its drinking water is typically small, and its buoyancy tank is normally at more than the water surface, is squeezed typically by buoyancy tank
By formulating corresponding mooring scheme by ball；And tension leg platform (TLP) is typically small due to absorbing water, therefore, the Major Difficulties of its mooring
It is：
1. tension leg platform (TLP) drinking water is larger, buoyancy tank is normally at below the water surface, with leaning on squeezing for ball etc. when being difficult to mooring
, therefore, can only be by circular abutment with being born against by ball etc. by effect, and circular column and the contact area by ball are smaller, by
The less stable of the effects such as stormy waves；
2. the tension force muscle take-up device of tension leg platform (TLP) bottom is the position of tension leg platform (TLP) most critical, it is in mooring process
In easily with harbour collide, cause the mooring difficulty of tension leg platform (TLP) to increase.
The content of the invention
It is a primary object of the present invention to overcome disadvantages mentioned above existing for prior art, and provide a kind of tension leg platform (TLP)
Pier mooring method, its can not only by tension leg platform (TLP) mooring on harbour, solve tension leg platform (TLP) mooring stability and
Easily with harbour collision problem；Moreover, also assures that the safe distance between tension force muscle take-up device and harbour, code is substantially increased
Head mooring process stablizes emerging and security, reduces tension force muscle take-up device and the risk of harbour collision during mooring, is
Tension leg platform (TLP) carries out mooring on harbour, there is provided technical guarantee.
The purpose of the present invention is realized by following technical scheme：
A kind of pier mooring method of tension leg platform (TLP), it is characterised in that：Using following mooring step：
The first step：Further the size of device according to the column spacing of tension leg platform (TLP) and tension force muscle, completes the design of barge
It is and prefabricated；
Second step：According to the arrangement of bollard on harbour, corresponding several anchor points are set on barge；
3rd step：Fixed along the length direction of barge in the both sides of barge and lean on ball；
4th step：Anchor point is fixed in the bollard of wharf apron；
5th step：Tension leg platform (TLP) is drawn to barge, and makes to be in close contact by the column of ball and tension leg platform (TLP)；
6th step：Tension leg platform (TLP) is fixed in bollard, and fastened；
7th step：By the anchor point set on barge, will be connected between barge and tension leg platform (TLP).
It is described concordant with the water line of barge by ball centre of buoyancy.
Beneficial effects of the present invention：The present invention is because using above-mentioned technical proposal, it can not only be by tension leg platform (TLP) system
Pool on harbour, solve tension leg platform (TLP) mooring stability and easily with harbour collision problem；Moreover, it also assures that tension force muscle is drawn
The tightly safe distance between device and harbour, substantially increase pier mooring process stablizes emerging and security, reduces mooring
During the collision of tension force muscle take-up device and harbour risk, mooring is carried out on harbour for tension leg platform (TLP), there is provided technology
Ensure.

Embodiment
As shown in Fig. 1-Fig. 7, the present invention uses following mooring step：
The first step：Further the size of device 3 according to the spacing of column 2 of tension leg platform (TLP) 1 and tension force muscle, completes barge 4
Design and prefabricated；
Second step：According to the arrangement of bollard 8 on harbour 7, corresponding several anchor points 5 are set on barge 4；
3rd step：Fixed along the length direction of barge 4 in the both sides of barge 4 and lean on ball 6, and lean on eating for the centre of buoyancy of ball 6 and barge 4
Waterline is concordant；
4th step：By the several anchor points 5 being arranged on barge 4, before anchor point 5 is fixed on into harbour 7 using hawser 9
In the bollard 8 on edge；
5th step：Tension leg platform (TLP) 1 is drawn to the outside of barge 4, and makes the column 2 by ball 6 and tension leg platform (TLP) 1 close
Contact；
6th step：Tension leg platform (TLP) 1 is fixed in bollard 8 using hawser 9, and fastened；
7th step：By the anchor point 5 set on barge 4, will be connected between barge 4 and tension leg platform (TLP) 1 by hawser 9
Connect.
Mentioned strain leg platform, tension force muscle further device, column, barge, anchor point, by ball, be prior art, do not say
Bright technology is prior art, therefore is repeated no more.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, it is all
It is any simple modification, equivalent change and modification made according to the technical spirit of the present invention to above example, still falls within
