  • This invention relates to a method for erecting a drill rig on the seabed. More particularly, it relates to a method for placing a drill rig for the recovery of petroleum on the seabed, the method comprising: placing a base housing for a blow-out preventer, a so-called BOP, on the seabed; placing an intermediate housing on the base housing, the intermediate housing including drilling equipment, and the intermediate housing being designed to receive a utility function housing; placing a drilling housing on the intermediate housing, the drilling housing including pipe-handling equipment and lifting tackle; and connecting a utility function housing to the intermediate housing.
  • the invention also includes a device for practising the method.
  • Oil and gas deposits down in the earth's crust are recovered, as is known, by holes being drilled down to the deposits, so that oil and gas deposits can be drained up to the surface.
