Definitions

  • the present invention relates to an apparatus and method for deploying an object to a sea floor, and relates particularly, but not exclusively, to an apparatus and method for deploying an implement or structure to a sea floor from a vessel through sea ice.
  • US 3633530 discloses a submarine working vehicle having floating tanks which can be filled with air by means of an air supply conduit connected to a surface vessel.
  • this arrangement suffers from the drawbacks that it can only work effectively on even or smooth seabed surfaces, and the size of the working vehicle that can be deployed from a given size of surface vessel is severely limited.
  • an apparatus for deploying an object to a sea floor comprising: - a body;
  • attachment means mounted to the body for releasably attaching an object to the apparatus
  • thrust generating means mounted to the body for providing thrust to transport the apparatus having an object attached thereto;
  • buoyant means mounted to said body and having adjustable buoyancy
  • buoyant means comprises at least one tank adapted to be filled with air and/or gas by means of a conduit connected to a vessel located at the sea surface.
  • this provides the advantage of enabling the apparatus with an object releasably attached thereto to be transported from a vessel to a first location on the seabed by means of a cable, and then to a second location on the seabed by means of the thrust generating means subsequently to increasing the buoyancy of the combined apparatus and object by increasing the buoyancy of the buoyant means.
  • This in turn provides the advantage of enabling objects to be deployed to subsea locations laterally further from the location of a vessel than is presently possible, thereby enabling deployment to a wider range of locations .
  • Providing at least one tank adapted to be filled with air and/or gas by means of a conduit connected to a vessel located at the sea surface provides the further advantage of enabling a larger upthrust to be generated than is possible for an apparatus having on-board air tanks, thereby enabling larger objects to be manipulated.
  • the apparatus may further comprise at least one conduit adapted to be releasably connected to at least one said tank for filling said tank with air and/or gas from a vessel located at the sea surface.
  • the apparatus may further comprise release means for releasing at least one said conduit from the corresponding said tank.
  • the buoyant means may comprise at least one buoyant member adapted to be moved between a respective first position, for transport from a vessel to said first location, and a second position, for transport from said first location to a second location on the sea floor.
  • This provides the advantage of enabling the lateral dimensions of the apparatus to be minimised while passing through an aperture on the vessel, thereby maximising the size and payload of the apparatus that can be used for a given vessel aperture size.
  • the advantage is also provided of enabling the buoyant members to be located in respective lower positions before the buoyancy is increased, and at respective higher positions subsequently to the buoyancy being increased, thereby contributing to stability of the apparatus during deployment .
  • At least one said buoyant member may be pivotable between said first and second positions.
  • an apparatus for deploying an object to a sea floor comprising: - a body;
  • attachment means mounted to the body for releasably attaching an object to the apparatus
  • thrust generating means mounted to the body for providing thrust to transport the apparatus having an object attached thereto;
  • buoyant means mounted to said body and having adjustable buoyancy, wherein the buoyant means comprises at least one buoyant member adapted to be moved between a respective first position, for transport from a vessel to said first location, and a second position, for transport from said first location to a second location on the sea floor .
  • this provides the advantage of enabling the lateral dimensions of the apparatus to be minimised while passing through an aperture on the vessel, thereby maximising the size and payload of the apparatus that can be used for a given vessel aperture size.
  • the advantage is also provided of enabling the buoyant members to be located in respective lower positions before the buoyancy is increased, and at respective higher positions subsequently to the buoyancy being increased, thereby contributing to stability of the apparatus during deployment .
  • At least one said buoyant member may be pivotable between said first and second positions.
  • the buoyant means may comprise at least one tank adapted to be filled with air and/or gas.
  • At least one said tank may be adapted to be filled with air and/or gas by means of a conduit connected to a vessel located at the sea surface.
  • the apparatus may further comprise at least one conduit adapted to be releasably connected to at least one said tank for filling said tank with air and/or gas from a vessel located at the sea surface .
  • the apparatus may further comprise release means for releasing at least one said conduit from the corresponding said tank.
  • the apparatus may further comprise power supply means for operating at least one implement releasably mountable to said attachment means .
  • the power supply means may comprise at least one hydraulic power unit.
  • the apparatus may be adapted such that the centre of mass of the vehicle with an implement mounted thereto when suspended in air is at a different location from the centre of buoyancy of the vehicle with an implement mounted thereto when suspended in water.
  • This provides the advantage of enabling the apparatus to be used to deploy an implement such as a blow out preventer for sealing an oil or gas well while enabling an umbilical deploying the apparatus to avoid damage from harmful products being emitted from the well.
  • This in turn provides the advantage of enabling the apparatus to be used for this purpose in shallow water, while enabling the surface vessel operating the apparatus to be laterally separate from the well.
  • the power supply means may be arranged adjacent an edge of the apparatus.
  • This provides the advantage of simplifying construction of the apparatus by enabling the weight of the power supply means to be balanced by the weight of the buoyant means .
  • the apparatus may further comprise at least one aperture for enabling flowing material to pass therethrough.
  • This provides the advantage of assisting operation of the apparatus in deploying a blow out preventer.
  • the apparatus may further comprise at least one implement adapted to be releasably attached to said attachment means . 14 068553
  • the implement may comprise sea floor removal means and/or locating means for locating at least one elongate object in a trench.
  • the implement may comprise sealing means for sealing an oil and/or gas well.
  • a method of deploying an object to a sea floor comprising: - attaching an object to attachment means of an apparatus as defined above;
  • the method may further comprise deploying said apparatus and object to said first location through an aperture in a vessel located in sea ice.
  • the method may further comprise deploying said object to the sea floor at said second location by generating downward force on the apparatus by means of said thrust generating means.
  • the step of increasing said buoyancy may comprise filling at least part of said buoyant means with air and/or gas .
  • an apparatus for displacing material from a sea floor comprising: a body: thrust generating means mounted to the body for providing thrust to transport the apparatus; and displacement means for generating a flow of water to the sea floor to displace material therefrom.
  • this provides the advantage of enabling a displacement apparatus such as an excavator to be used independently of a surface vessel, thereby enabling access to previously inaccessible locations .
  • the thrust generating means may be adapted to provide thrust having a vertical component.
  • This provides the advantage of enabling a downward thrust to be generated by the apparatus, to counteract an upward thrust generated by the displacement means, thereby enabling a displacement means of higher power to be used.
  • the displacement means may comprise at least one fan.
