Definitions

  • the present invention relates to an arrangement for controlling a compensated drill floor on a floating drilling or intervention vessel, which is a vessel for carrying out well drilling, completion, workover and/or production operations at the sea.
  • the invention acts to neutralise tidal influence on the position of the drill floor in relation to the sea bottom.
  • Floating drilling and intervention vessels must have some means to compensate for the heave exerted on the vessel by the sea.
  • An object of the present invention is to indicate an arrangement which can control a compensated drill floor and simultaneously neutralise tidal influence on the drilling systems.
  • Figure 1 shows an embodiment of an arrangement according to the invention, in particular how the tide can be neutralised by means of a frame-like structure (1) which is mounted fixed to the compensated drill floor (7).
  • a tidal structure (3) is mounted which can move freely inside the frame-like structure and is positioned by means of cylinders (2) in such a way that the distance between the top of the riser pipe (6), which connects submarine safety valve (10) and the drill vessel, and drill floor can be adjusted at the same rate as the tide without influencing the drill floor compensator system.
  • the cylinders are coupled to the drill floor compensator system to act as a secondary stretch system for the riser pipe system.
  • Figure 2 shows an embodiment of an arrangement according to the invention, in particular how a tidal structure (3) is mounted below the compensated drill floor (7).
  • the tidal structure is suspended in a complicated wire system in which one end of the wire is attached to the compensated drill floor, while the other end of the wire is attached to a riser pipe compensator (26). Normally 4 to 10 such wire systems will be mounted to a tidal structure. Further, the figure shows how control of the tidal structure is arranged to achieve a precise positioning.
  • Figure 3 shows an embodiment of an arrangement according to the invention, in particular how the tidal structure (3) can be employed as a lift for subsea modules so that the modules can be safely lifted into the vessel even if it is moving in a fashion which would otherwise prohibit such a lifting operation.
  • Figure 1 shows an embodiment of an arrangement according to the invention for neutralising the tidal influence on a drill floor compensator system.
  • the arrangement is installed in a drilling and intervention vessel 16.
  • the vessel comprises a moon pool 32. This is an opening in the hull through which tools like a drill string etc. can be lowered into the sea.
  • a riser pipe system 6 is shown passing through the moon pool 32 and down to the sea bottom 19.
  • the drilling unit comprises a drill floor 7 with a derrick. At the top of the derrick the draw works are installed.
  • the whole unit is suspended by means of hydraulic heave compensator cylinders 10.
  • the cylinders are coupled to a hydraulic circuit, which causes the cylinders to expand and contract in unison with the movements of the vessel. In this way the rolling of the vessel is compensated, so that the drilling crew is working in a stable environment without movement caused by the surrounding seas.
  • a frame-like structure (1) is mounted with longitudinal vertical guides (4).
  • a structure (3) is mounted, here called a tidal structure, which can move vertically in the guides (4) by means of tidal cylinders (2).
  • the tidal structure includes a rotational swivel (5) fixed to the riser pipe system (6).
  • the riser pipe system (6) connects the tidal structure (3) to the subsea safety valve (18) in such a way that an anchoring of the compensated drill floor (7) to the sea bottom is established.
  • the drill floor compensator cylinders (10) can continuously operate around their middle position as the control valve (11) regulates the position of the tidal structure (3) as the tide (17) changes the vertical distance between the sea bottom (19) and the vessel (16). This is achieved automatically by the drill floor compensator cylinders (10) changing their middle position in step with the tide (17) and by the control signal (14) activating the control cylinder (11) for changing the position of the tidal structure (3) so the drill floor compensator cylinders (10) can compensate around their middle position at all time.
  • the change in vertical length between the tidal structure (3) and the compensated drill floor (7) is taken up by a telescopic tube (8) to establish a continuous tubular connection between drill floor (7) and subsea safety valve (18) independently of the movement of the tidal structure (3).
  • the tidal cylinders (2) are connected to an accumulator system (12) to function as a secondary stretch system for the riser pipe system (6).
  • FIG 2 an embodiment of the invention is shown, for measuring the influence of the tide on the drill floor compensator system and positioning the compensated drill floor so the drill floor compensator cylinders can operate around their middle position even if the tide changes the relative position of the vessel.
  • the frame-like structure (1) with tidal cylinders (2) is removed, and instead the tidal structure (3) is supported in the drill floor (7) in a wire system.
  • a measuring string (24) is installed between the compensated drill floor (7) and the tidal structure (3).
  • the measuring string (24) is tied at one end to the tidal structure (3) in an anchoring point (28).
  • the other end goes to a reel (23) which is installed on the compensated drill floor (7).
  • the reel (23) maintains a constant tension in the measuring string (23) regardless of the relative movement between the compensated drill floor (7) and the tidal structure (3).
  • the tidal structure (3) with installed rotational swivel (5) keeps the riser pipe structure (69) in constant stretch against the vessel (16). This is achieved by means of a compensated wire system in which the tidal structure (3) is suspended.
  • the compensated wire system includes a wire (25) which in a first end is attached to the compensated drill floor (7) in an anchoring point (28).
  • the wire (25) runs down to a sheave (27), which is fixed to the tidal structure (3).
  • the wire runs further up to a tensioning compensator (26) which is attached to the vessel (16).
  • the tensioning compensator (26) maintains the riser pipe system (6) in the desired stretch against the subsea safety valve (18).
  • the measuring string (23) will output a continuous measuring signal to the position gauge (22) which is installed on the compensated drill floor (7).
  • the position gauge (22) will output an immediate and precise control signal to the control valve (20), whereby an adjustment of the drill floor compensator cylinders (10) can be made to keep the distance between the compensated drill floor (7) and the tidal structure (3) constant at all times, regardless of the movements of the vessel (16).
  • Figure 3 shows how an arrangement according to the invention is used in real time for retrieving and lowering subsea modules through the vessel's moonpool (32).
  • the tidal structure (3) is arranged to have a position in level with the vessels deck (31) when the compensated drill floor (7) is in its upper position with the drill floor compensator cylinders (10) at maximum length of stroke.
  • the subsea safety valve (18) is placed inside the tidal structure (3) and connected to the riser pipe system (6).
  • the tidal floor (3) is lowered by means of the drill floor compensator cylinders (10) to its lower position which is so arranged that the tidal structure is level with the vessels bottom (29).
  • the safety valve (18) is docked to the tidal structure (3) and locked to this to enable it to be lifted onto the vessel's deck by means of the drill floor compensator cylinders (10).
