Definitions

  • Floating well intervention arrangement comprising a heave compensated work deck and method for well intervention
  • the present invention relates to a floating arrangement device comprising a heave- compensated work deck and a method for implementing a well intervention by means of coiled tubing.
  • a riser When overhauling a well at sea with a floating arrangement according to the prior art, a riser is usually placed between the well and the floating arrangement.
  • the floating arrangement On account of the sea's movements, the floating arrangement will usually have at least a partially vertical movement in the water, and in order to avoid damage to the riser it is important to prevent this vertical movement from being transferred to the riser.
  • heave compensators are employed which are attached to the floating device and the riser, keeping the riser at constant tension independently of the floating arrangement's vertical movement. This means that the end of the riser is at rest, while the drill floor on the floating arrangement has a vertical movement as a result of the wave motion in the water.
  • the vertical movement of the floating arrangement makes it difficult for personnel located on the drill floor to carry out work on the devices at the end of the riser.
  • An object of the present invention is therefore to produce a dedicated floating installation which is arranged for implementing rapid connection of amongst other things coiled tubing for intervention on a hydrocarbon well. Another object is to improve the safety of personnel and equipment on the floating arrangement during connection of coiled tubing for intervention on hydrocarbon wells. It is also an object to reduce the time spent in connecting coiled tubing for intervention on hydrocarbon wells.
  • a floating arrangement for overhauling hydrocarbon wells at sea by means of coiled tubing, where the floating arrangement comprises a drill floor and a work deck which is arranged in an opening in the drill floor.
  • the opening may be a closed opening or a recess in the drill floor.
  • the floating arrangement comprises a first set of heave-compensating devices which are arranged for connection to a slip joint connected to a riser in such a manner that an approximately constant tension in the riser can be maintained when the floating arrangement moves in the water.
  • the floating arrangement further comprises a second set of heave-compensating devices which are arranged for connection to the work deck in such a manner that the work deck is at an approximately constant distance from the seabed, where the work deck can move relative to the drill floor and the floating arrangement moves in the water.
  • the drill floor and the work deck are preferably provided with rail devices, thereby enabling a coiled tubing frame to be moved from the drill floor on to the work deck.
  • the coiled tubing frame may be stored on the drill floor, and can be moved by means of rails out on to the work deck which is then secured to the drill floor by means of hydraulic lock bolts or other suitable devices capable of securely locking the work deck.
  • the first set of heave compensators may comprise two ore more separate heave compensators which may be mounted on the drill floor, where the heave compensators comprise wires or telescopic connections which can be connected to the slip joint connected to the riser.
  • the heave compensators may also be mounted at other points on the floating arrangement if so desired.
  • the heave-compensated work deck may be connected to two or more heave- compensating devices via wires or hydraulic cylinders.
  • the heave-compensating devices are preferably also mounted on the drill floor, but may also be mounted at other points on the floating arrangement if so desired.
  • the work deck is preferably arranged so as to be able to be locked in a fixed position relative to the drill floor by means of, as mentioned above, one or more securing devices provided in the work deck and/or the drill floor.
  • the work deck may therefore be locked in a given position relative to the drill floor, or it may be heave-compensated, which basically means that the work deck does not move vertically relative to the seabed while the drill floor naturally follows the floating arrangement's vertical movements in the water.
  • the floating device preferably comprises control devices which control the work deck's substantially vertical movement relative to the drill floor.
  • first set of heave-compensating devices and the second set of heave-compensating devices are arranged to be able to heave- compensate the slip joint device/the riser and the work deck respectively independently of each other. This is necessary during the preparations for coupling up coiled tubing for intervention on a hydrocarbon well before it is connected to a high-pressure riser passing through the slip joint to the surface blow-out preventer, where during the intervention the coiled tubing frame will be arranged on the work deck.
  • the first set of heave-compensating devices and the second set of heave- compensating devices are also arranged for synchronous heave compensation of the slip joint/the riser and the work deck. This is necessary when the connection has taken place.
  • a method is also provided for overhauling hydrocarbon wells at sea from a floating arrangement by means of a coiled tubing frame, where the floating arrangement comprises a drill floor and a work deck and where the work deck is arranged in an opening in the drill floor.
  • the floating arrangement further comprises a first set of heave-compensating devices which can be connected to a slip joint, and a second set of heave-compensating devices which can be connected to the work deck.
  • a riser is furthermore prepared for receiving coiled tubing, whereby at least
  • the slip joint is mounted on the upper end of an upper riser, where the upper riser is mounted at its lower end on the top of the surface blow-out preventer, - the work deck is secured in a fixed position relative to the drill floor in such a manner that the work deck is located on approximately the same level as the drill floor, and
  • the first set of heave-compensating devices are connected to the slip joint in such a manner that a constant tension in the riser is maintained when the floating device moves in the water.
  • a constellation is obtained where the work deck is locked in a fixed position relative to the drill floor and at the same level as the drill floor, thereby enabling the coiled tubing frame to be moved over on to the work deck.
  • a high- pressure riser extending from the seabed is connected to a surface blow-out preventer.
  • On the top of the surface blow-out preventer it is connected to a riser extending up to the slip joint.
  • the slip joint, and thereby also the riser, is heave- compensated by the first set of heave-compensating devices.
  • the method for coupling up the coiled tubing frame and preparing the floating device for an intervention on the hydrocarbon well comprises the following steps:
  • a further step in the method comprises suspending the high-pressure riser in the work deck before the coiled tubing frame is moved from the drill floor on to the work deck.
  • a further step in the method comprises attaching a block to the coiled tubing frame before the work deck is released and lowered, with the result that at least a part of the weight of the work deck and the riser is supported by the block.
  • the work deck may be released and lowered so that at least a part of the weight of work deck and riser is supported by the second set of heave- compensating devices connected to the work deck.
  • a further step in the method is to arrange for the first set of heave-compensating devices for the slip joint/riser and the second set of heave-compensating devices for the work deck to compensate synchronously when the high-pressure riser and the surface blow-out preventer are interconnected.
  • the invention also comprises a use of a floating arrangement according to one of the claims 1-8 during intervention of a hydrocarbon well at sea, together with a use of a method according to one of the claims 9-13 during intervention of a hydrocarbon well at sea.

  • One or more lengths of a high-pressure riser 34 are lowered from the work deck down through the slip joint 36. As many lengths are lowered as are necessary to enable the high-pressure riser 34 to reach almost right down to the surface blow-out preventer 30, but not so far down that it bumps into the surface blow-out preventer 30 when the floating arrangement 10 moves vertically in the water on account of the wave movements. This is indicated by the distance 41 in figure 1.
