Abstract
The invention discloses a safety device of a floating drilling platform on sea during typhoon or hurricane, which comprises an upper riser, a lower riser assembly, a blowout preventer, a lower riser and a buoy floating in the sea, The blowout preventer is set on the buoy; the lower riser is installed at the lower part of the blowout preventer; and the upper riser is arranged on the lower riser assembly which is detachably arranged on the blowout preventer. In the invention, a floating buoy is arranged in the sea, and when typhoon or hurricane comes during deepwater drilling, all it is required to do is to recycle the upper riser and leave the blowout preventer and the lower riser on the buoy after turning off the blowout preventer; therefore, the evacuation time is saved, the load of the platform on sea is reduced, and the deepwater drilling platform can conditionally withdrawal to the safe sea area; and after the typhoon or hurricane leaves, the deepwater drilling platform resumes operations of drilling and sea area exploration, thereby guaranteeing the safety of platform on sea.
Description
Technical field
The present invention relates to a kind of safety device of floating drilling platform on sea during typhoon or hurricane that be used for.
Background technology
Present stage, routine was when deepwater drilling is kept away typhoon or hurricane, and normally that preventer (BOP) device is the above marine riser of offshore platform all reclaims and causes on the offshore platform, and offshore platform could safe escape.Existing preventer all is mounted on the sea bed well head, like this, in the time the marine riser more than the preventer (BOP) all will being recycled on the offshore platform, can increase the load of offshore platform on the one hand, on the other hand because marine riser is very long, to all pack up and need long time, usually owing to have little time that marine riser is packed up typhoon or hurricane and just come, safety in order to ensure the offshore platform personnel, the offshore platform of not packing up marine riser can only be placed the original place and personnel are withdrawn, thereby cause the damage of marine riser and offshore platform, this loss is huge often.
Summary of the invention
Problem at the prior art existence, the object of the present invention is to provide the safety device of a kind of floating drilling platform on sea during typhoon or hurricane, offshore platform is withdrawn fast, guaranteed offshore platform safety, and can not increase the load of offshore platform.
The safety device of a kind of floating drilling platform on sea provided by the invention during typhoon or hurricane comprises: top marine riser, bottom marine riser assembly, preventer, bottom marine riser and be suspended in floating drum in the ocean, preventer is arranged on this floating drum, the bottom marine riser is installed in the bottom of preventer, the top marine riser is arranged on the marine riser assembly of bottom, and described bottom marine riser assembly detachably is arranged on the described preventer.
Preferably, link to each other with bottom marine riser assembly by the lower flexible joint at described top marine riser.
The present invention is provided with the floating drum of suspension in the ocean, when deepwater drilling runs into typhoon or hurricane, close preventer (BOP), as long as reclaim the top marine riser, and still stay preventer (BOP) device and bottom marine riser on the floating drum, not only saved the time of withdrawing, reduced the load of offshore platform, and made the deepwater drilling platform to have ready conditions to evacuate to safe marine site; After typhoon or hurricane were calmed down, the deepwater drilling platform returned drilling well, exploitation marine site, proceeds operation again, has guaranteed the safety of offshore platform.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A portion enlarged diagram of Fig. 1.
The specific embodiment
As shown in Figure 1, the present invention includes: top marine riser 2, preventer (BOP) 4, bottom marine riser 6 and be suspended in floating drum 5 in the ocean 9, one end of bottom marine riser 6 is installed on the floating drum 5, and this end is provided with top well head 11, and the other end of bottom marine riser 6 is installed on the sea bed well head 8 of sea bed 7.Preventer 4 is installed on the top well head 11, and top marine riser 2 links to each other with bottom marine riser assembly (LMRP) 10 by lower flexible joint 3, and bottom marine riser assembly 10 detachably is arranged on the preventer 4.
The present invention is by being installed in preventer 4 on the floating drum 5, and bottom marine riser assembly 10 detachably is arranged on the preventer 4, like this, when deepwater drilling runs into typhoon or hurricane, can close preventer 4 earlier by offshore platform 1, reclaim top marine riser 2 and bottom marine riser assembly 10 then fast, and preventer 4 devices and bottom marine riser 6 are still stayed on the floating drum 5.Floating drum 5 can be arranged on 200～300 meters, plane off sea, can significantly reduce the length that need be recovered to the marine riser on the offshore platform 1 on the one hand, thereby significantly reduced the receipts pipe time, not only saved the time of withdrawing, reduced the load of offshore platform 1, and made deepwater drilling platform 1 to have ready conditions to evacuate to safe marine site; After typhoon or hurricane were calmed down, deepwater drilling platform 1 returned drilling well, exploitation marine site, proceeds operation again, has guaranteed the safety of offshore platform 1.
Claims (2)
1. the safety device of a floating drilling platform on sea during typhoon or hurricane, it is characterized in that, comprise: top marine riser, bottom marine riser assembly, preventer, bottom marine riser and be suspended in floating drum in the ocean, preventer is arranged on this floating drum, the bottom marine riser is installed in the bottom of preventer, the top marine riser is arranged on the marine riser assembly of bottom, and described bottom marine riser assembly detachably is arranged on the described preventer.
2. device as claimed in claim 1 is characterized in that, links to each other with bottom marine riser assembly by the lower flexible joint at described top marine riser.
