摘要： A drilling vessel has a moonpool, an upper deck of a deckbox structure, and a drilling installation with a drilling tower. Adjoining the moonpool a subsea BOP storage room is provided. BOP handling cart rails and a BOP handling cart allow for transfer of a subsea BOP (between the BOP storage room and a position aligned with the firing line. A mobile working deck is configured to be elevated relative to a stationary resting position and to be movable within a motion range including a heave compensation motion range. Vertically mounted working deck compensator cylinders are arranged between the deckbox structure and the mobile working deck.

摘要： An aspect of the present invention relates to a wellbore drilling system comprising a drilling tower and a tubular racking device having at least a lower first tubular racker assembly and at least a second tubular racker assembly operable at a greater height than the first tubular racker assembly. The system further comprises one or more well center tools, each adapted for operation above the well center of the drill floor, e.g. an iron roughneck tool for making up and breaking out of threaded tubular joints. According to the present invention, the tubular racking device comprises a third tubular racker assembly which is vertically mobile and which is operable for tubular transfer between the firing line and the drilling tubulars storage rack in combination with the second tubular racker assembly, e.g. in case of failure of the first tubular racker assembly, and wherein at least one well center tool is adapted to be connected to the motion arm of the third tubular racker assembly, which well center tool is operable above the drill floor, whilst the first and second tubular racker assemblies are operable in combination for tubular transfer between the firing line and the drilling tubulars storage rack.

摘要： An offshore system includes a vessel having a deck; a cantilever which is mounted on the deck and which is moveable in a longitudinal direction of the cantilever relative to the deck between a retracted position and an extended position, and which is rotatable relative to the deck about a substantially vertical swivel axis; and actuators to move the cantilever in longitudinal direction and to rotate the cantilever about the swivel axis. The swivel axis is provided by a single sliding and swivel assembly arranged at one end of the cantilever, including a fixed part mounted to the deck and a sliding part mounted to the cantilever. The sliding part is arranged to slide in longitudinal direction of the cantilever relative to the fixed part when the cantilever moves in the longitudinal direction. The fixed part and/or the combination of fixed part and sliding part are configured to form the swivel axis allowing the cantilever to rotate relative to the deck. A sliding assembly is arranged at the other end of the cantilever supporting the cantilever and allowing the cantilever to slide in longitudinal direction of the cantilever relative to the deck during movement of the cantilever in longitudinal direction, and to slide in a transverse direction perpendicular to the longitudinal direction relative to the deck during rotation of the cantilever relative to the deck.
