A well intervention apparatus including a base frame assembly, a deck attached to an upper end of the base frame assembly. The deck includes a passage and a hatch adjacent to the passage. A track is disposed within the passage, and a movable plate is slidingly attached to the track for movement within the passage. A reception plate is attached over a first aperture of the moveable plate and a tower is mounted over a second aperture of the moveable plate. A primary hoist assembly is connected to an upper end of the tower. The reception plate is configured to secure a first well intervention tool, and the primary hoist assembly is configured to suspend a second well intervention tool from the tower. In a first position of the moveable plate, the reception plate is disposed over the well. In a second position, the tower is disposed over the well.

Well intervention apparatus and method

An apparatus for performing well intervention work using coiled tubing. The apparatus includes a structural frame. The upper portion of the frame include two winches for suspending well interventions tools including a coiled tubing injector head. The winches may be selective reciprocated by a hydraulic cylinder to either bring the first or second winch into operative alignment into or out of alignment with a subsea wellhead.

Coiled tubing inline motion eliminator apparatus and method

An apparatus having a modular support frame with a top deck. The top deck has a passage therein. A tower is mounted on the top deck. A moveable plate and a track are positioned within the passage. The movable plate is slidingly attached to the track. A support rotary table is disposed within the modular support frame and suspends jointed tubulars. A coiled tubing injector head interface plate is operatively attached to the movable plate, and positioned over the first aperture of the movable plate. The first aperture is positioned over the well in a first position. A rotary table is positioned over the well in a second position. The apparatus is mounted on a transport vehicle in a transport position and moved to a well site. A lifting mechanism lifts the apparatus into an upright position. Well intervention work is conducted with coiled tubing and jointed tubulars.

Coiled tubing well intervention system and method

The movable plate is slidingly attached to the track. A support rotary table is disposed within the modular support frame and suspends jointed tubulars. A coiled tubing injector head interface plate is operatively attached to the movable plate, and positioned over the first aperture of the movable plate. The first aperture is positioned over the well in a first position. A rotary table is positioned over the well in a second position. Well intervention work is conducted with the coiled tubing and jointed tubulars.

An apparatus for performing well intervention work on a rig. The apparatus comprises a first spreader that is operatively connected to a derrick, a pair of I-beams that have a distal end and a proximal end, and wherein the distal end of the pair of I-beams are connected to the first spreader. The apparatus further comprises a second spreader, and wherein the proximal end of the I-beams is connected to the second spreader. The apparatus further comprises a first pivot point on the first spreader and a second pivot point on the second spreader. In the most preferred embodiment, the apparatus further comprises a door, operatively attached to the second spreader, for allowing entry of the tubular. Also, the second spreader may include a shoulder for engagement with a tubular so that the tubular is supported by the second spreader so that the weight of the tubular can be transferred to the second spreader. A method of lifting a tubular used in well intervention work on a rig is also disclosed.

Articulating bail assembly and method

An apparatus for supporting a structure on a platform. The platform may be a floating platform. The apparatus comprises a base frame, wherein the base frame has a first bracket and a second bracket attached thereto. The apparatus further includes a x-axis frame having a first pivot point and a second pivot point. The apparatus further comprises a z-axis frame having a third pivot point and a fourth pivot point. A sliding frame assembly is operatively positioned within the z-axis frame, and wherein the sliding frame assembly has a plurality of rods for connecting with an injector head. The apparatus may further include a motion restriction system that restricts movement of the x-axis frame and the z-axis frame. The sliding frame assembly comprises a sliding pad for lateral movement. A method for compensating for the movement of a floating platform having a riser extending therefrom is also disclosed.

Apparatus and method for supporting structures on offshore platforms

An apparatus for lifting and moving a load. The apparatus comprises a lift frame having a first and second vertical member that are connected so that a working window area is defined. The apparatus further comprises a rotary actuator mounted on the first vertical member, and an arm having a first end and a second end, and wherein the first end of the arm is pivotly connected to the rotary actuator. The arm is pivotal from an area exterior of the working window area to an area within the working window area. The apparatus may further comprise a winch, operatively attached to the arm, for lifting a load with the cable. A method of lifting a load is also disclosed.

Swing arm crane and method

A system for providing motion compensation of a platform attached to an ocean floor. The platform is operatively associated with a riser extending from a subterranean well. The system comprises a frame member positioned on the platform and a deck slidably attached to the frame member, and wherein the deck is attached to the riser. The system further comprises a moving device for moving the frame member relative to the deck. In one of the preferred embodiments, the frame member contains a plurality of guide post and wherein the deck is slidably mounted on the guide post so that the frame member is movable relative to the deck. The moving device may comprise a cylinder member operatively attached to the frame member and a piston operatively attached to the deck and wherein the system further comprises a pressurized recharging vessel configured to direct a pneumatic supply to the cylinder member, and a gas delivery mechanism for keeping the cylinder member within a pressure range. A method of compensating for movement on an offshore platform during well operations is also disclosed.
