Definitions

  • This invention relates to apparatus for use with a subsea wellhead assembly, and in particular to an apparatus for use in providing a source of pressurised fluid for a subsea wellhead assembly.
  • a number of individual wells may be controlled from a single central platform.
  • the oil or gas may be piped from the subsea wellheads, controlled from the central platform, to suitable locations on land, or to a buoy or storage vessel for collection and transportation by tanker.
  • the various wellhead assembly controls and apparatus such as the blow ⁇ out preventer (BOP) stack, are also monitored, powered and controlled from the central platform. This requires provision of multicore "umbilical" cables extending between the central platform and each wellhead, which cables may be 40 km long.
  • the hydraulic fluid necessary to operate, for example, the valves and rams on a BOP stack is supplied through such cables and, in order to compensate for pressure losses over the long distance between the platform and wellhead, must be provided initially at very high pressure.
  • the umbilical cables carrying the hydraulic fluid must be of heavy construction.
  • the cost of the cables linking the platform and wellheads, and the cost of maintaining the cables may represent a significant proportion of the commissioning and running expenses of such an operation.
  • apparatus for use with a wellhead assembly comprising: first means for supplying or generating power; and second means utilising said power for pressurising fluid for use in actuating elements of the wellhead assembly, at least said second means being provided at or adjacent to the wellhead assembly.
  • the invention has particular application in subsea wellheads which are controlled remotely from, for example, a central platform.
  • the provision of the second means locally to the wellhead assembly obviates the need to provide lengthy fluid conduits from a source of pressurised fluid on the platform to actuate valves, rams and the like on the wellhead assembly.
  • the first means is in the form of a generator, located at or adjacent to the wellhead, and includes a turbine, propeller or the like to be driven by sea currents.
  • the turbine may be linked directly to the second means, in the form of a fluid pump or the like, or may drive an electrical generator which is used to drive an electrical pump, either directly or via a rechargeable battery.
  • Other forms of generator including wind, wave and tidal generators may be provided, dependant on local conditions.
  • the first means may be in the form of a battery or other electrical storage device located on or adjacent to the wellhead, and capable of supplying power for driving a fluid pump.
  • the battery may be chargeable or non-rechargeable.
  • a rechargeable battery may be maintained in a charged condition by an electrical supply from a central platform.
  • a "trickle charge” may be utilised to maintain the battery in a charged state.
  • the first means may be in the form of a generator located on the central platform, linked to the second means by a suitable transmission link. However, this would require provision of relatively expensive high- voltage subsea cabling.
  • the first means may also include other forms of energy storage means, such as reservoirs of compressible fluid or even explosive charges.
  • the second means is located on the wellhead assembly.
  • the second means may be spaced from the assembly: in a subsea wellhead assembly, the second means may be located on the sea floor and may supply a plurality of wellhead assemblies, or may be located on the surface in a buoy, barge, or other form of vessel.
  • the wellhead assembly 10 includes various hydraulically actuated valves, rams and the like for use in controlling the flow of oil or gas from the associated well through a pipeline 14 to an appropriate storage or collection point, and through a blow out preventer (BOP) 15.
  • BOP blow out preventer
  • the operation of the various elements of the assembly 10 is controlled from a remote central platform via one or more umbilical cables 16.
  • a single central platform may control a number of wellhead assemblies, which may be up to 40 km distant from the platform.
  • the apparatus 12 is mounted on the wellhead assembly
  • the 10 includes a turbine 18 which is adapted to be driven by sea currents, indicated by the arrows 19.
  • the turbine 18 includes an electric generator, and the output of the generator is supplied to a rechargeable battery 20.
  • the battery is linked to an electric motor 22 which is used to drive a hydraulic fluid pump 24 linked to a hydraulic fluid reservoir 26.
  • the cable 16 includes various control lines through which signals may be sent to control the actuation of the valves, rams and the like of the assembly 10. Any electrical power that is required for such operations may be drawn from the battery 20, while any action requiring hydraulic actuation is achieved by running the electric motor 22 to drive the pump 24 for an appropriate length of time, to direct pressurised fluid to the appropriate assembly element .
  • the power output of the turbine 18 will be modest, but electrical and hydraulic power are likely to be required only periodically, such that a trickle charge from the turbine 18 will be sufficient to maintain the battery in a charged state.

Abstract

Dispositif conçu pour être utilisé avec un ensemble tête de puits sous-marin (10) et composé d'une source d'énergie et d'une pompe (24) mettant en application ladite énergie afin de mettre sous pression un liquide permettant de mettre en mouvement les éléments dudit ensemble (10). La pompe (24) est conçue pour être placée au niveau de l'ensemble tête de puits (10) ou en position contiguë audit ensemble. La source d'énergie peut être une roue à commande hydraulique (18) située au niveau de l'ensemble tête de puits (10) ou en position contiguë audit ensemble, ou peut être un générateur situé sur une plate-forme centrale placée à distance. Cette source d'énergie peut fournir une charge lente, afin de conserver la charge de la batterie, cette dernière étant utilisée pour entraîner la pompe (24) si nécessaire.
