Definitions

  • drilling takes place with the aid of conventional dynamically positioned or firmly moored drilling ships which are also equipped with brackets for the suspension of risers, preferably on the outside of the hull.
  • the arrangement solutions are used in areas where weather conditions are more moderate, and where the ship basically can lie in a fixed direction which is co-linear with the dominant wind direction.
  • the ship may be firmly moored or based on dynamic positioning, a solution particularly relevant where great ocean depths are involved.
  • drilling takes place from a ship having a geostationary turret with production risers, and where the drilling centre is positioned outside the turret.
  • Such ships are also normally intended for use in areas where weather conditions are moderate, as they are chiefly meant to use the drilling package only when the ship is able to lie in certain fixed directions.
  • An arrangement of this kind has the best potential for use in more exposed environments, such as the North Sea, west of Shetland and the Norwegian Sea.
  • a ship can drill irrespective of the direction from which the forces of wind and weather come, and can adjust its position to the direction which gives least motion for the drilling operation.
  • a recurrent feature in the proposed arrangements in that they are largely based on existing turret solutions for pure production purposes.
  • a typical and well known solution in the last-mentioned category is to place the derrick and drill floor up on the actual turret, so that the drilling system is geostationary together with the moorings and the risers.
  • drag chain which is located on and supported by the turret
  • a related and somewhat improved variant of the last-mentioned arrangement is to lift the drilling package off the turret and support it directly from the ship's deck by means of a separate support structure.
  • the gain here is that the turret is relieved of the associated loads, and that it becomes considerably easier to arrange the drilling mud process (as on a conventional exploration rig).
  • the same problem remains as with the arrangement where the derrick and drill floor are arranged on the actual turret, namely the elevated height of the structure, the weight of the drag chain, and problems of clearance for the risers in the so-called moonpool, i.e., the vertical opening in the turret.
  • the elevated height of the structure is due to the fact that the blow-out preventer (BOP) must be handled at a level above the drag chain, preferably at an upper turret level, and that the drill floor and derrick will be positioned many metres (as a rule about 15 metres) above this level.
  • BOP blow-out preventer
  • the high level of the drill floor causes problems as regards centre of gravity and not least as regards the clearance in the turret opening for the risers.
  • the invention relates to an arrangement of the last-mentioned type, and the object of the invention is to provide a new and improved arrangement for a combined drilling/production ship of the last-mentioned category.
  • an arrangement is proposed for a drilling/production ship having geostationary anchoring, including a turret in the form of a substantially hollow cylindrical body, which turret is pivotally supported about a vertical axis in a through opening in the vessel, a vessel-supported drill floor above the turret, guides means for risers in the turret, and a drag chain for the transfer of production from the risers to a deck on the vessel, which arrangement according to the invention is characterised in that it includes a vertical pipe rack which extends down from the drill floor and into the through opening in the turret, a lateral access opening in the vertical pipe rack on a level with the drag chain, and that the drag chain is designed to have a free circumferential area, or is constructed having an opening in a circumferential area
  • the drill floor is supported on the vessel's deck at such a height as to enable a BOP or other largish equipment units to be manoeuvred from the vessel's deck and into the turret through the lateral opening.
  • the blow-out preventer is to be capable of being brought inside the turret, the drag chain must not block the lateral opening.
  • Such clearance is in theory completely possible by locating the starting point of the drag chain on the side of the turret and the end point of the drag chain on the deck of the vessel so that in a particular sector or particular circumferential section it is possible to cross the drag chain track when the vessel is lying in the dominant wind direction.
  • the lateral access opening can also be cleared by breaking a circumferential area of the drag chain, i.e., its utilised support structure, naturally on the condition that the drag chain (the pipes) are not in this area in the particular vessel orientation.
  • the new arrangement is also especially distinctive because the volume or space below the drill floor is used for vertical storage of pipes, such as risers for drilling and drill pipes. As this vertical pipe rack is suspended from the drill floor or the drill floor support structure, the pipe rack will be stationary relative to the vessel and to the drill floor that is stationary relative to the vessel.
  • the vertical pipe rack may to advantage be incorporated in a cylindrical structure coaxial with the turret. This means that the available space or volume below the drill floor and on the inside of the drag chain is put to good use. 4
  • this support structure may be designed to have a removable circumferential section opposite the lateral access opening.
  • the arrangement may advantageously be constructed so that the lateral opening will be freely accessible from the vessel's deck, in the area not covered by the drag chain in the dominant wind direction.
  • An especially preferred embodiment of the arrangement according to the invention is one wherein the drag chain is "inverse", i.e., that it is supported by and moves on the vessel's deck, an inner part of the chain following the movement of the turret, whilst the outer part rests on the vessel's deck.
  • the inner part of the drag chain will follow the movement of the turret, and move relative to the vessel's deck (scrubber), whilst the outer part of the drag chain rests on the deck of the vessel.
  • the drag chain In a "normal" and known embodiment of the drag chain, the drag chain is positioned on the actual turret and is set in motion with the aid of a securing structure (derrick) which projects up from the vessel's deck with fixed piping.
  • the drag chain's turning arrangement includes a planet wheel unit which has driving engagement with the turret (sun wheel) and with a rotating drive ring in the vessel, direct or via the drag chain.
  • a rotating bull nose of this kind will cause a "lifting" of the chain from the ship's deck and will place it on the turret.
  • the planet wheel will to advantage be made so that the engagement with the chain is synchronous will the chain's travel from inner to outer track and vice versa, i.e., the same radius for the planet wheel as the turning radius of the chain. In this way, chain movement friction against the underlying surface will be avoided. In all positions, the drag chain will rest against the underlying surface, if the transverse movement which takes place when the chain enters and exits the planet wheel is disregarded.
  • the planet wheel solution will be especially advantageous if it is used simultaneously for dynamic braking of the turret relative to the orientation of the ship. Safety is increased considerably by controlling the planet wheel. A substantial reduction in capacity for operating the turret is obtained if the procedure is based on the use of forces (moment) from moorings and risers to turn the turret. This can be achieved by turning the ship actively with the aid of thrusters 7 - 15° beyond the desired turning. As the angle of friction is reached, a controlled movement will be obtained.
  • a trackway leading in towards a lateral opening for transport of the blow-out preventer This trackway intersects the drag chain path and runs towards a lateral opening in the turret for a particular vessel orientation.
  • the trackway may, for example, be made as a recessed track which meets similar tracks in the turret.
  • a transport trolley running on the trackway will be capable of rolling onto tracks which are suspended in the support structure of the drill floor, so that the transport of the blow-out preventer can take place in the very centre of the turret, at the so-called cellar deck level.
  • the blow-out preventer BOP
  • the blow-out preventer will be capable of being suspended from the drill floor and lowered down through the moonpool to the seabed by means of a drill/riser.
  • the planet wheel unit may to advantage be incorporated in a carriage, which carriage is moveable in a guide track around the turret.
