Abstract
The upper structure dragging and installing method for marine platform includes marine mooring of the transporting ship and the installation of the upper structure on the lower structure of the marine platform. The present invention features that both the upper structure carrying ship and the lower structure top are provided with slideway and the slideway in the carrying ship and that in the lower structure top are leveled and jointed through regulating the load of the carrying ship for lifting or lowering and horizontal position regulation with tug boats. In the said conditions, the upper structure is installed with lifting lugs in the upper structure, the fixed pulley in the lower structure and winch in the ship. The present invention has low cost.
Description
Technical field
The present invention is the innovation of upper structure of offshore platform installation method.
Background technology
Existing upper structure of offshore platform is to the installation method that is built in marine bottom section, can be summed up as two kinds: a kind of is that topside is delivered ship after the bottom section of having built is nearby in place, utilize crane barge that topside is lifted the top of bottom section, this is the most frequently used method; Another kind is topside to be delivered ship to be dragged to the place ahead of column of the bottom section of having built in place, utilize the Lifting Equipment of special arrangement on the delivery ship that topside is risen again, make its outer column top elevation that props up a little higher than bottom section of point height that is suspended from the bottom of ship side both sides, then topside being delivered ship pulls in the middle of the column of the bottom section of having built, the column top of topside bottom fulcrum and bottom section is aligned, utilize decline of ebb tide water level or operation Lifting Equipment that topside is transferred again, make it to be seated at bottom section column top, this method claims FLOAT-OVERDECK that method is installed abroad.
More than two kinds of method common features be that the platform topside all must rely on vertical movement (slinging or jacking) to realize from the transfer of delivery ship to the bottom section top, thereby need relatively large lifting or Lifting Equipment, its equipment is higher with running expense.The objective of the invention is to create a kind of new method, make topside change horizontal displacement into by vertical movement to the transfer at bottom section top, thereby realize by light rigging tractive, to reach the purpose of the marine erected cost of remarkable reduction, this is so-called platform topside tractive installation method.
Summary of the invention
A kind of upper structure of offshore platform tractive installation method comprises: the platform topside is delivered the marine in place of ship, and topside transferred to the installation that is built in marine flat-bed bottom section top from the delivery ship, it is characterized in that the installation that topside is transferred to the bottom section top from the delivery ship is the horizontal tractive method of employing.The precondition of implementing this horizontal tractive method is that the top of sharp bottom section all is provided with slideway on the delivery ship of topside, and must make slideway on the delivery ship reach to flush with the slideway at bottom section top to dock.Can utilize delivery ship self to transfer for this reason and carry the realization heave, by tugboat and the positioning of fishing boat traction realization level.Just can utilize the hanger that lies in topside bottom with this understanding, be located at the fixed pulley at bottom section top and be loaded on winch on the delivery ship and realize that topside shifts to the tractive at bottom section top and install.
Description of drawings
Be described further below in conjunction with drawings and Examples.
Fig. 1 is platform topside delivery ship procedure chart in place near bottom section.
Fig. 2 is that platform topside delivery ship deck slideway docks and the tractive rigging plan with bottom section end face slideway.
Among the figure: the 1-bucket foundation; The 2-casing; The 3-gin pole; The anti-ice piton body of 4-; 5-is by the ship pad; 6-vertebra top slideway; 7-deck slideway; 8-vertex of a cone bitt; 9-leg post; The 10-slide plate; The 11-fixed pulley; The 12-winch; The 13-barge; The 14-tugboat; The 15-guy rope; The 16-cable; The 17-water surface; 18 mud faces; The 19-topside; The 20-hanger; The 21-fishing boat; 22 anchor hawsers.
The specific embodiment
Is that example is illustrated at this with the anti-ice of the only post of bucket foundation flat-bed topside.The gin pole (3) in this flat-bed ice action district (from minimum to highest water level) has an anti-ice piton body (4) on every side, and rising is leverage topside (19) more than the end face, and topside (19) has four leg posts (9) to insert anti-ice piton body (4).Comprise below the anti-ice piton body (4) that gin pole (3), casing (2) and bucket foundation (1) are the platform bottom section, have from floating and self-installability energy.Figure 1 shows that the barge (13) that is installed on marine bottom section state and delivery topside (19) is drawn to the close state of the anti-ice piton body of bottom section (4) by tugboat (14) and fishing boat (21).Slideway (7) in the planar view on the demonstration barge and the slideway (6) on the anti-ice piton end face are near mated condition.But remain in horizontal clearance and elevation difference at joint, this elevation difference is transferred to carry by barge (13) and is eliminated, and horizontal clearance then relies on tugboat (14) and fishing boat (21) to draw and coincide.Figure 2 shows that vertex of a cone slideway (6) finishes the state that docks that flushes with deck slideway (7), the cable (16) between this moment vertex of a cone bitt (8) and barge is fastened barge (13), cone flank by ship pad (5) simultaneously with barge (13) by the jail.There is slide plate (10) transition on the surface of slideway butt end, with this understanding, tugboat (14) and fishing boat (21) are withdrawn, and just can utilize the rigging system that topside (19) level on the barge slideway (7) is pulled on the anti-ice piton face slideway (6), aim at installation in position, finish structure and install.Tractive rigging shown in Figure 2 system installs hanger (20) on the crosspiece of the front-seat leg of topside column bottom, the central installing of anti-ice piton end face leading edge fixed pulley (11), the barge middle part is provided with winch (12), guy rope (15) is the company of wearing successively, starts winch (12) and just topside (19) is pulled to the bottom section top.
Claims (2)
1. upper structure of offshore platform tractive installation method, comprise the platform topside is delivered the marine in place of ship, and topside transferred to the installation that is built in marine platform bottom section top from the delivery ship, it is characterized in that the installation that topside is transferred to platform bottom section top from the delivery ship is the horizontal tractive method of employing.
2. according to the upper structure of offshore platform tractive installation method of claim 1, it is characterized in that tractive installation method that the platform topside shifts to platform bottom section top from the delivery ship is that accent by topside delivery ship carries heave and utilizes after positioning makes the slideway of deck flush with the slideway of bottom section end face to align to barge rigging system such as pulley winch to realize again in that tugboat and fishing boat are auxiliary down.
