A system, including one or more supports disposed on a drill floor. The system also includes a movable support slidingly coupled to the one or more supports and configured to be selectively moved towards the drill floor during a tripping-in operation as part of a continuous tripping operation and away from the drill floor during a tripping-in operation as part of a continuous tripping operation, and a tripping apparatus coupled to the movable support and configured to make up or break out a threaded joint between a first tubular segment and a second tubular segment, wherein the tripping apparatus is configured to be selectively movable from a first position disposed proximate to the one or more supports and a second position at a distance away from the one or more supports to make up the threaded joint when the tripping apparatus is disposed in the second position during the tripping-in operation or to break out the threaded joint when the tripping apparatus is disposed in the second position during the tripping-out operation.

A sensor assembly is provided for a fingerboard latch assembly that comprises: a latch bracket; bolts for mounting the latch bracket to a fingerboard; a latch; and a bracket pin rotatably supporting the latch on the latch bracket to allow rotation of the latch between an open position and a closed position. The sensor assembly has a mounting arrangement that mounts to the bolts, holding a closed-position proximity sensor probe facing downwardly for sensing proximity of a crank portion of the latch and/or the piston head in the closed position, and also holding an open-position proximity sensor probe facing forwardly for sensing proximity of an arm of the latch in the open position.

A system includes a crate and a deployer. The crate is configured to contain a plurality of elongated rods; the crate has a length, width and height. The deployer includes a bed frame upper surface, a crate support frame, a tilt mechanism and a scope mechanism. The crate support frame includes an attachment mechanism configured for removable attachment of the crate, wherein the crate support frame has a longitudinal extent aligned with the length of an attached crate. The tilt mechanism is configured to move the crate support frame between a horizontal position parallel to the bed frame upper surface and a vertical position normal to the bed frame upper surface. The scope mechanism is configured to move the crate support frame linearly along its longitudinal extent. A method of deploying a plurality of rods to a selected location is also described.

A method for assembly of a riser string onboard a vessel for performing subsea wellbore related operations involving said riser string, the riser string extending between a subsea wellbore and the vessel in a wellbore related operation, wherein the vessel includes a hull, a riser storage storing therein, in horizontal orientation, multiple pre-assembled riser stands and/or multiple individual riser stand, a deck structure having an elongated transfer opening above said riser storage, a transfer elevator, wherein multiple pre-assembled riser stands, each being pre-assembled from multiple riser sections connected end-to-end and each having a length of at least 150 ft. (45.72 m), and/or multiple individual riser sections each having a length of at least 150 ft. (45.72 m), are stored, in said horizontal orientation, in the riser storage.

A sensor assembly is provided for a fingerboard latch assembly that comprises: a latch bracket; bolts for mounting the latch bracket to a fingerboard; a latch; and a bracket pin rotatably supporting the latch on the latch bracket to allow rotation of the latch between an open position and a closed position. The sensor assembly has a mounting arrangement that mounts to the bolts, holding a closed-position proximity sensor probe facing downwardly for sensing proximity of a crank portion of the latch and/or the piston head in the closed position, and also holding an open-position proximity sensor probe facing forwardly for sensing proximity of an arm of the latch in the open position.

An offshore drilling rig comprising a drill deck, at least one primary well center and a diverter system arranged below the primary well center, a drilling support structure extending upwardly from the drill deck and above the primary well center and the other work center and a first and a second hoisting system supported by the drilling support structure and being adapted for raising or lowering a first and a second load carrier, respectively, and where the offshore drilling rig comprises a positioning system adapted for selectively positioning at least the first load carrier in at least a first or a second horizontal position different from the first horizontal position, where the first load carrier in the first horizontal position is positioned above the primary well center, and in the second horizontal position is positioned above the other work center.

A fingerboard latch arrangement includes an elongate support member, a latch which moves from a closed position into an open position and from the open position into the closed position, and an activation member which is connected to and which is movable longitudinally along the elongate support member. The activation member includes means to bring the latch from the closed position into the open position and from the open position into the closed position.

A system, including one or more supports. The system also includes a movable platform slidingly coupled to the one or more supports and configured to be selectively moved towards a drill floor and away from the drill floor. The system further includes a roughneck disposed on the movable platform and configured to make up or break out a threaded joint between a first tubular segment and a second tubular segment, wherein the roughneck is configured to be selectively movable along the movable platform from a first position disposed adjacent to the one or more supports and a second position disposed adjacent to the first tubular segment and the second tubular segment.

A method for assembly of a riser string onboard a vessel that is adapted to perform subsea wellbore related operations involving said riser string, said riser string being configured to extend between a subsea wellbore and the vessel in a wellbore related operation, wherein the vessel including a hull, a riser storage adapted to store therein, in horizontal orientation, multiple pre-assembled riser stands and/or multiple individual riser stand, a deck structure having an elongated transfer opening above said riser storage, a transfer elevator, wherein multiple pre-assembled riser stands, each being pre-assembled from multiple riser sections connected end-to-end and each having a length of at least 150 ft. (45.72 m), and/or multiple individual riser sections each having a length of at least 150 ft. (45.72 m), are stored, in said horizontal orientation, in the riser storage, wherein the method comprises a riser transfer step wherein the transfer elevator is operated so as to raise a single one of said pre-assembled riser stands and/or individual riser sections in the horizontal position thereof from the riser storage, through the transfer opening, to a position above the deck structure.
