State.
The operation principle of FDPSO of the present invention based on separable inner cupola formula anchoring system is as follows：
During common operating mode, under the influence of wind, wave, stream, hull 100 is by the effect of weathercock effect, freely around inner cupola formula
Anchoring system 200 rotates, and makes the fore body of hull 100 forever towards minimum stress surface.
When floating ice is met with the operating mode of polar region, hull 100 can actively be rotated around inner cupola formula anchoring system 200, make hull 100
Fore body meet ice so that ice load suffered by hull 100 is minimized.
When meeting with bad weather condition, such as tropical storm or thick ice when is emergency work condition, carries out detached job, drilling well at this time
Standpipe 32 stops circulation of drilling fluid, closes oil transportation tube valve, disconnects production tube 33, floating drum 12 is declined along drilling riser pipe 32,
Intelligence control system controls the ballast water of floating drum 12, and by controlling anchor chain separation adjusting connector 52 to adjust 51 length of anchor chain, makes
3213 are placed exactly in the lower bulkhead of inclined waterproof cabin 121 and hydraulic clamping manipulator 127 at 12 dive of floating drum to marine riser merogenesis
Between locate, carry out detached job.Hydraulic clamping manipulator 127 coordinates top driving device 143 to separate drilling rod 322 and marine riser 321, together
When sealed valve 323 is closed.When detaching top rod 3221 and top marine riser 3211, the inclined of floating drum 12 is first pumped it to
In waterproof cabin 121, the lower hatch door of inclined waterproof cabin 121 is closed, then is fully drawn out, closes the upper-deck cabin of inclined waterproof cabin 121
Door.So far, mask work terminates.After ship determines safety, coordinate intelligent control system, sail back and bore position,.Coordinate ship's fix
Function hull 100 stretches out top rod 3221, is accurately docked with floating drum 12, is inserted into by the upper hatch door of inclined waterproof cabin 121 floating
Cylinder 12, hydraulic clamping manipulator 127 coordinates top driving device 143 to complete the reconnection of drilling rod 322, then stretches out top marine riser 3211,
Floating drum 12 is inserted into by the upper hatch door of inclined waterproof cabin 121, hydraulic clamping manipulator 127 coordinates top driving device 143 to complete water proof
The reconnection of pipe 321.Intelligence control system controls the ballast water of floating drum 12, and by controlling anchor chain separation adjusting connector 52 to adjust anchor
51 length of chain, makes floating drum 12 float along top marine riser 3211, reinserts in floating drum cave mechanism 13, passes through buoy connector
132 are fixedly connected.Reconnection production tube 33, opens oil valves, opens sealed valve 323, and liquid transfer system 30 recovers work
Make, capstan head 10 resets, and reconnection work is completed.
