Definitions

  • a system for se in offshore petroleum production The invention relates to a system for use in offshore oil and gas production from production wells on the sea bed, 5 comprising a submerged buoy having an outer buoyancy member which is arranged for introduction and releasable fastening in a submerged, downwardly open receiving space in a vessel, and a central member which is rotatably mounted in the outer member and is anchored to the sea bed and is connected to at least one 0 transfer line extending from a respective production well up to the buoy, a shaft extending between the receiving space and the deck of the vessel.
  • a system of the above-mentioned type, for use in buoy loading and unloading, is disclosed in the international patent s application No. PCT/N092/00054.
  • the submerged buoy forms a collecting point for one or more flexible risers and umbilical cables from e.g. a production system at the sea bed.
  • the buoy is adapted to be raised and fastened in the receiving space of the topical vessel, to establish a transport system for o the petroleum products from said system to holds in the vessel.
  • the vessel When a buoy of the introductorily stated type is secured in the receiving space in a vessel, the vessel is rigidly fastened to the outer buoyancy member of the buoy and is rotatable about the central member of the buoy which is anchored 5 to the sea bed by means of a suitable mooring system.
  • the buoy itself constitutes a turning body or turret about which the vessel is allowed to turn under the nfluence of wind, waves and water currents.
  • This buoy structure involves a number of essential 0 advantages in relation to the previously known buoy loading sys ⁇ tems.
  • the central member of the buoy has a small diameter and a small mass, so that a correspondingly small diameter is obtained of the turning body, i.e. the outer buoyancy member of the buoy, and therewith a small rotary mass and a small rotational 5 resistance.
  • Connection and disconnection between vessel and buoy can be carried out in a simple and quick manner, even in bad weather with relatively high waves. Further, the buoy may remain connected to the vessel in all weathers, a quick disconnection being able to be carried out if a weather limitation should be exceeded .
  • the receiving space and the shaft arranged thereabove suitably are arranged in the bow portion of the vessel, as shown in the above-mentioned international patent application.
  • This makes possible a relatively simple and cheap rebuilding of existing vessels for adaptation to such a buoy loading system, for use as shuttle tankers.
  • the combination of a submerged receiving space and a shaft which extends between the receiving space and the deck of the vessel, in addition makes possible a system giving a high security in operation and a small risk for contaminating spills.
  • a system of the introductorily stated type which, according to the invention, is characterized in that it comprises a swivel unit which is installed at the lower end of the shaft so that it is limitedly raisable and lowerable, and which is connected to a tube system on the vessel, the swivel unit comprising inner and outer mutually rotatable swivel members and at its underside is provided with a number of coupling heads for interconnection with corresponding connectors arranged at the upper ends of the topical number of transfer lines, these lines at their upper end being suspended at the upper end of the central member of the buoy.
  • a substantial advantage of the system according to the invention is that it gives reduced system dimensions because of the use of the special buoy which itself constitutes a turning body. This results in weight saving and a reduced equipment volume, something which gives substantially reduced costs.
  • the system according to the invention requires minimum rebuilding of shuttle tankers for the introductorily stated buoy loading system, for transition to production vessels.
  • a production vessel With such a production vessel, seasonal operations will be possible, in addition to continuous production from marginal fields, and also test production.
  • the ship for example may be used for test production during the summer half in a period with a possible excess of shuttle tankers.
  • the system according to the invention will be suitable for use in connection with water injection, water purification plants, well stimulation, pumping of oil from ship wrecks located at the sea bed, etc.
  • the system also is suitable for use in waters having floating ice and icebergs, the system when required making possible a quick disconnection, without any risk for damage of the submerged buoy.
