Abstract
The underwater mating guide peg pre-install, reclaimed, comprising: a fixed bar, is sleeved on the guide rod on fixed bar top, wherein, is provided with a taper type transition piece between fixed bar and guide rod; This guide rod top is provided with a recovery shackle plate; The surrounding of guide rod is symmetrically installed with several retainer ring.The utility model is simple to operate, by land with regard on energy mounting structure thing, can not only install lower water with works; Solve the problem being inconvenient to connect guide peg under water; And, again can under water under robot manipulation, achieve docking of guide peg and structure; Meanwhile, the quick recovery of guide peg can also be realized, guide peg is reused.
Description
Technical field
The utility model relates to guide peg, particularly relates to a kind of underwater mating guide peg pre-installed, reclaim for underwater production facility.Belong to Offshore Engineering field.
Background technology
Production technology under water for oil and gas development is the forward position high-tech technology of modern marine petroleum industry, is also the indispensability successfully developed of deep water marine oil and gas and basic technology.Along with the exploitation of China's marginal basins deep water hydrocarbon resource, production technology is widely applied under water, and increasing underwater production facility comes into operation gradually.But, because the physical dimension of some underwater facility and weight are all comparatively large, add the factor of facility counterweight, the ability of lifting resource when often substantially exceeding conventional Attention problems.And rely on merely searching installation resource, improve the Attention problems that loop wheel machine ability meets facility, normally unpractical way.Consider the factors such as the Lifting Capacity of Attention problems crane barge, installation procedure, installation economy, usually adopt piecemeal to lift for some underwater structure, carry out under water docking the mode of assembling.
At present, the existing guide peg for underwater production facility docking assembling, its main body is column round bar, and top is taper or hemispherical seeker, and bottom is fixed on and is installed in the structure in seabed.Works to be installed is provided with guide peg with the use of bottom be the butt muff of bell mouth shape.By guide peg to be completed the docking of works to be installed through butt muff.
The existing guide peg for underwater mating assembling, usually have two kinds of fixing meanss, the first is: directly welded structurally by guide peg, install with structure, but guide peg can not reclaim; The second is: be separated with structure by guide peg, is installed in structure under water by guide peg, installs after terminating, then reclaims guide peg.
Be installed under water at lower part block structure because first kind of way mostly adopts, then guide peg is installed to the mode on the piecemeal of bottom, compare and expend time in; In order to avoid top piecemeal collides the equipment on the piecemeal of bottom, it is higher that guide peg generally all designs, and after works assembling, guide peg goes out to be exposed on the outside usually.After the assembling of structure piecemeal terminates, the risk that the guide peg giving prominence to works top can cause underwater robot (ROV) umbilical cables, fishing net etc. to pull, needs the guide peg of exposure to remove.Therefore, the method for imderwater cutting can only be adopted to remove for first kind of way, what it brought is with high costs.For the second way, need to connect guide peg under water, due to the complexity that it connects, equally, it also needs high mounting cost.Therefore, being badly in need of one neither needs to install under water, again the convenient guide peg reclaimed.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and the underwater mating guide peg providing a kind of and pre-install, reclaim, and it just on mounting structure thing, can not only can install lower water with works by land; Solve the problem being inconvenient to connect guide peg under water; And, under water under robot (ROV) operation, docking of guide peg and structure can be achieved again; Meanwhile, the quick recovery of guide peg can also be realized, guide peg is reused.
The purpose of this utility model is realized by following technical scheme:
The underwater mating guide peg pre-install, reclaimed, is characterized in that: comprising: a fixed bar, is arranged on the guide rod on fixed bar top, wherein, is provided with a taper type transition piece between fixed bar and guide rod.
Described guide rod top is provided with a recovery shackle plate; The surrounding of guide rod is symmetrically installed with several retainer ring.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, and it is simple to operate, by land with regard on energy mounting structure thing, can not only install lower water with works; Solve the problem being inconvenient to connect guide peg under water; And, under water under robot (ROV) operation, docking of guide peg and structure can be achieved again; Meanwhile, the quick recovery of guide peg can also be realized, guide peg is reused.

Detailed description of the invention
As shown in Figure 1, the utility model comprises: fixed bar 1, adopts welding manner to be arranged on the guide rod 2 on fixed bar 1 top, wherein, is provided with a taper type transition piece 3 between fixed bar 1 and guide rod 2; Guide rod 2 top adopts welding manner to be provided with and reclaims shackle plate 4, and surrounding's employing welding manner of guide rod 2 is symmetrically installed with several retainer ring 5.The retainer ring 5 of the present embodiment is two.
As shown in Fig. 2-Fig. 6, when the bottom piecemeal 8 of production facility lifts installation, the recovery shackle plate 4 of the utility model upper end is connected with recovery rope 6, guide rod 2 side is temporarily fixed at by recovery rope 6, fixed bar 2 is inserted in the guide peg slot 10 of the bottom piecemeal 8 of production facility, two retainer rings 5 respectively cable 7 fixing with two are connected, and the other end of fixing cable 7 is fixed in the structure of bottom piecemeal 8, and what realize guide peg is fixing.After guide peg is fixing, guide peg will be lifted into seabed with bottom piecemeal 8, avoid the installation under water of guide peg.
When carrying out structure docking, first cut off by underwater robot (ROV) the fixing cable 7 be connected with guide peg, by the loop wheel machine on installation ship, top piecemeal 9 is lifted into water, by the horizontal level of the mobile adjustment top piecemeal 9 of installation ship, by the position of the vertical direction of the folding and unfolding adjustment top piecemeal 9 of loop wheel machine hawser, the pilot sleeve 11 in upper chunk 9 is progressively moved to the guide peg top that will dock; When guide rod 2 top of guide peg is in below pilot sleeve 11 bell-mouth structure of air, in good time transfers top piecemeal 9, makes guide peg pass pilot sleeve 11, achieves the position guiding in horizontal plane of top piecemeal 9 and bottom piecemeal 8 and location.When top piecemeal 9 is transferred on bottom chunk 8 along guide peg, achieve the location on vertical direction under gravity, if need to realize simultaneously towards location; the guide peg needing at least 2 height different and the pilot sleeve 11 coordinated with it respectively, after two guide pegs coordinate with corresponding pilot sleeve 11 respectively, can realize top piecemeal 9 towards location.
After top piecemeal 9 docks with bottom piecemeal 8 and assembles, by underwater robot (ROV), recovery rope is freed from guide rod 2, and be articulated on the suspension hook of mounting shipping loop wheel machine, by receiving loop wheel machine cable, guide peg is recovered on ship deck, completes recovery.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
