    Abstract: A system and method for casing drilling with a subsea casing drive adapted to engage at the outer circumference of the casing string, to impart a linear force and/or torque to the casing string, and such a subsea casing drive per se are disclosed. During drilling, the subsea casing drive is provided in a subsea unit further comprising a blowout preventer, a pressure control device and a mud pump with an outlet to a mud hose connectable to a surface vessel. The wellbore is drilled by driving the bottom hold assembly, BHA, and the casing string into the wellbore by the subsea casing drive, while discharging mud and cuttings via the mud hose and supplying mud to the BHA from the mud circulation system on the vessel via the landing string and casing string.

    Abstract: A combination of a drilling installation for drilling a well and a control and signal lines deployment module is disclosed. The drilling installation includes a rig floor slip device adapted to be cleared from a well centre opening to create a clear space around the well centre opening. The combination includes a temporary workspace floor, adapted to be mounted in the clear space at a level below a rig floor surface and to provide a workspace floor for an operator standing in said clear space on the work space floor, allowing the operator to secure at a securing level said one or more control/and or signal lines externally to a second tubulars string suspended from a module slip device.

    Abstract: 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.

    Abstract: The invention relates to a drilling vessel (1) comprising a drilling tower (2) and a tubular string support structure (3) for supporting a tubular string in the firing line (4a, 4b) of the drilling tower. The tubular string support structure comprises two parallel rails (11) and two carts (13, 14) supported by those rails. Both carts have a hanger body (14, 15), comprising a central passage (16), for supporting a tubular, and each cart (13, 14) can be moved between a central support position (18) for supporting a tubular in the firing line, and a secondary position (19) adjacent the central support position. When both carts (13, 14) are located in their secondary position (19), the carts are located on opposite sides of the firing line, such that between the carts there is a passage for passing through large objects along the firing line.

    Abstract: The invention relates to a drilling vessel for drilling in the earth's surface, comprising a dual firing line and a suspension carriage to move strings of drilling tubulars between the two firing lines, wherein the suspension carriage is provided with a stationary first suspension device and a moveable second suspension device, so that the second suspension device only requires a relatively small sideways motion in order to pass a string of drilling tubulars present in a firing line and to allow the first suspension device to approach and engage said string of drilling tubulars. The invention further relates to a method for replacing a string of drilling tubulars for another string of drilling tubulars in which use is made of a drilling vessel according to the invention.
