A drilling rig transfer system includes a mobile transfer beam, a trolley assembly operatively attached to and moveable along the mobile transfer beam, and a connection mechanism suspended from the trolley assembly for connecting to and lifting a device. The mobile transfer beam is suspended from first and second traveling blocks through connections at first and second suspension positions along the mobile transfer beam. A method of transferring a device may include suspending a connection mechanism from the trolley assembly over a first location, lowering and attaching the connection mechanism to a device disposed at the first location, lifting the device with the connection mechanism, moving the trolley assembly along the mobile transfer beam to position the connection mechanism and the device over a second location, and lowering the connection mechanism and the device into the second location.

Drilling rig transfer system and method

Methods and apparatus are provided for running tubulars into and out of a wellbore. A tubular handling system having a tubular gripping apparatus having a gripping mechanism and a sensor adapted to track movement of the gripping mechanism, wherein the sensor sends a signal to a controller when the gripping apparatus is in a position that corresponds to the gripping apparatus being engaged with the tubular.

Apparatus for gripping a tubular on a drilling rig

A control line running system includes a control line storage unit and a guiding system having a guiding device and a guide rail for guiding a control line from the control line storage unit toward a well center. The system may also include a control line manipulator assembly for moving the control line toward a tubular and a control line clamp for attaching the control line to the tubular.

Control line running system

A fill-up and circulation tool includes a mandrel; a packer assembly is disposed around the mandrel; and a valve assembly connected to the mandrel, wherein the valve assembly is configured to selectively control fluid flow into the tool and out of the tool.

Embodiments of the invention relate to a gripping apparatus for supporting a tubular. The gripping apparatus may include a housing, a slip assembly disposed in the housing, and a leveling ring operable to move the slip assembly in the housing. The gripping apparatus may further include a guide member and a mating member operable to couple the slip assembly to the leveling ring. The longitudinal movement of the leveling ring directs the mating member along the guide member to radially displace the slip assembly relative to the housing.

Methods and apparatus for supporting tubulars

Methods and apparatus for running tubulars into and out of a wellbore. A gripping apparatus is activated with an actuator having a primary actuator and a redundant safety feature. The redundant safety feature may include one or more redundant fluid operated pistons. The gripping apparatus may include an integrated safety system adapted to prevent damage to the tubulars while making and breaking out connections between the tubulars and the tubular string.

Aspects of the present invention provide a tubular handling system for handling wellbore tubulars. In one aspect, the present invention provides a tubular handling system adapted to retain a tubular without damaging the outer surface of the tubular. In another aspect, the present invention provides a method of connecting tubulars by remotely controlling the connection process, including joint compensation, alignment, make up, and interlock. In one embodiment, the tubular handling system comprises an elevator adapted to support a tubular utilizing a first portion of an upset of the tubular and a spider adapted to support the tubular utilizing a second portion of the upset. In another embodiment, at least one of the elevator and the spider is remotely controllable. In yet another embodiment, the tubular handling system comprising a joint compensator system adapted to provide fluid communication to the elevator during rotation of the tubular.
