摘要： An elevator system that supports a tubular member includes an elevator movable between a first elevator position and a second elevator position. A mechanical signal mechanism is coupled to the elevator. A valve is coupled to the mechanical signal mechanism. The mechanical signal mechanism is configured to transmit a mechanical signal by a mechanical control cable to move the valve into a valve position to send a valve signal that the elevator is in the second elevator position.

摘要： An actuator assembly with integrated torque turn monitoring is described. Embodiments include a rotationally fixed outer hydraulic section and a rotationally independent inner hydraulic section which incorporates torque load sensors, axial load sensors, and rotational speed sensors directly into the inner hydraulic section. The inner hydraulic section is coupled to an outer cage by a cage ring and is axially movable relative to the inner mandrel. Upper and lower fluid chambers are disposed between the outer housing assembly and the inner mandrel. Fluid pumped through a lower pressure port into the lower chamber moves the housing assembly in a first direction, and fluid pumped through an upper pressure port into the upper fluid chamber moves the housing assembly in a second direction.

摘要： An apparatus for gripping a tubular includes a body. A slip carrier is coupled to an inner surface of the body. The slip carrier is configured to pivot between an open position and a closed position. A tubular is configured to be introduced laterally into the body when the slip carrier is in the open position. A slip is coupled to the slip carrier. The slip is configured to move radially between a first position that is spaced apart from the tubular and a second position that contacts and grips the tubular.

摘要： An offshore drilling vessel includes a floating hull subjected to heave motion. The hull includes a moonpool and a drilling tower near the moonpool. A drilling tubulars storage rack is provided for storage of drilling tubulars. The vessel includes a heave motion compensation support that is adapted to support a slip device whilst performing heave compensation motion relative to the heaving motion of the vessel. A racking device is provided with a heave motion synchronization system that is adapted to bring a tubular retrieved from the storage rack in heave motion into a vertical motion that is synchronous with the heave compensation motion of the string slip device. The racking device includes vertical rails and at least two separate motion arm assemblies mounted on said vertical rails. Each separate motion arm assembly includes its own vertical drive which is electrically connected to the heave motion synchronization system.

摘要： In one aspect there is provided an apparatus to transmit hydraulic force to a snubbing unit's traveling slip assembly. The apparatus comprises a first hydraulic power source having a hydraulic connection to the traveling slip assembly, a hydraulic power source actuator to actuate the hydraulic power source to cause it to transmit hydraulic force to or from the traveling slip assembly. Rotation isolation means are provided to rotationally isolate the hydraulic power source actuator from the first hydraulic power source, and to transfers axial and radial loads between the hydraulic power source actuator 65 and the first hydraulic power source. The first hydraulic power source is mounted to the traveling slip assembly so as to co-rotate therewith.

摘要： An elevator for use in handling a tubular includes a first body part coupled to a second body part; and at least two slips coupled to each of the first and second body parts, wherein one or more of the slips includes an engagement member for coupling with a mating member of the first body part or the second body part, wherein at least 25% of the engagement member is coupled with the mating member when the slip is in an open position. In another embodiment, a swivel includes an upper housing rotatably coupled to a lower housing; and a rotary union having a rotating body attached to the lower housing and a non-rotating body attached to the upper housing, wherein the swivel is configured to transfer load from the lower housing to the upper housing.

摘要： A gripping tool for gripping oilfield tubulars includes a gripping element having a substrate, and at least one gripping surface configured to engage an oilfield tubular, the at least one gripping surface being formed on the gripping element. The at least one gripping surface includes a coating on an outer surface of the substrate, the coating includes a carrier and a plurality of particles at least partially embedded in the carrier. The particles each have a hardness that is greater than a hardness of the carrier and a base metal of the gripping element, and the particles extend outward from the carrier and are configured to engage a structure that is gripped by the gripping tool.

摘要： A drill rod clamping system for securing a drill rod in a selected position. The drill rod clamping system has a hollow spindle with an upper portion that defines axial slots and a base portion that defines at least one radial opening. A plurality of jaws are moveable radially inwardly to a drill rod gripping position and radially outwardly to a drill rod releasing position. Each jaw is received within a respective axial slot of the hollow spindle. An actuator moves the plurality of jaws between the drill rod gripping position and the drill rod releasing position. A compressed gas spring assembly exerts force on the actuator to close the jaws. A hydraulic operator exerts force on the actuator to overcome the force of the compressed gas spring assembly to open the jaws. The radial openings of the base portion of the spindle permit flushing of material flowing within the spindle.
