A carrier assembly for a catwalk assembly includes a carrier. The carrier assembly includes a skate to move a tubular member along the carrier. The carrier assembly includes a proximity sensor positioned to detect the end of the tubular member as it moves along the carrier. The carrier assembly includes a skate position sensor. The length of the tubular member may be determined by measuring the position of the skate relative to the proximity sensor when the end of the tubular member passes the proximity sensor.

A powered unit with a reeving system for supporting a load associated with operation of the powered unit, the reeving system having a first cylinder with a first cylinder end coupled with a raising leg of the powered unit, and a second cylinder end having a first rod movingly disposed therein. There is a movable sheave spreader engaged with the first rod, and having a first spreader sheave, the movable sheave spreader also movably engaged with the powered unit.

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 releasable lock (11) for a pipe cradle is disclosed. The releasable lock (11) comprises an elongate arm (1), pivotally secured at a first end to a pivot end mounted on a cradle frame (12). At a second end the releasable lock comprises a locking element (3), said locking element (3) being moveable between a release position allowing pivoting of the elongate arm (1) about the pivot end and a gripping position preventing said pivoting. The pivot end is moveable about a pivot pin (10) housed on the cradle, said movement displacing the elongate arm (1) between a first release position allowing removal or addition of pipes (15) from/to a cradle and a second position in which pipes are secured in position in the cradle.

A utility umbilical module may include an expandable frame, a plurality of extendable fluid lines arranged on the expandable frame and configured for fluid coupling between a utility plant and a drill rig, an expandable and retractable electrical system configured for electrically coupling a utility plant to a drill rig, and a ground engaging portion configured for over-the-road transport of the module.

A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.
