A torque device for guiding a first torque device member relative to a second torque device member includes the first and second torque device members. Each of the torque device members has an operational axis of rotation and three clamp bodies spaced about the operational axis. The clamp bodies are movable between a retracted passive position and an extended active position. The torque device also includes a guide ring on one of the torque device members. The guide ring includes one or more guide ring sections. In addition, the torque device includes at least two guide elements on the other of the torque device members. Each guide element being movable with one of the clamp bodies of the respective torque device member. When the clamp bodies of the respective torque device member are in their retracted positions, the guide elements abut or are close to the guide ring, and when the clamp bodies of the respective torque device member are in their extended positions, the guide elements are moved away from the guide ring.

Torque device for oil field use and method of operation for same

A system on a marine vessel or platform supports a load while allowing heave compensation. The load is supported via a hydraulic actuator. A transformer of the system includes a power source and at least one hydraulic pump/motor, for communicating energy between any two of: the hydraulic actuator; a hydraulic accumulator; and a power source. A valve associated with the pump/motor is switchable during at least one cycle of the pump/motor for selectively providing fluid communication between a drive chamber of the pump/motor and any of the hydraulic actuator, the hydraulic accumulator, and a hydraulic fluid reservoir, via at least one port of the drive chamber, so as to allow a desired displacement of hydraulic fluid from the pump/motor to be obtained.

System arranged on a marine vessel or platform, such as for providing heave compensation and hoisting

An apparatus for applying torque about an operational axis of rotation includes a first torque device member. In addition, the apparatus includes an actuator support configured to move radially relative the operational axis and configured to be restricted from rotating in a plane oriented perpendicular to the operational axis. Further, the apparatus includes a first torque actuator pivotally coupled to the first torque device member and the actuator support. Still further, the apparatus includes a rod or a second torque actuator pivotally coupled to the first torque device member and the actuator support. Moreover, the apparatus includes a second torque device member coupled to the first torque device member and disposed about the operational axis of rotation. The actuator support is pivotally coupled to the second torque device member and is configured to pivot about a first pivot axis towards and away from the operational axis of rotation.

A die holder device includes a die holder that has an axial centre line and is adapted to receive a clamp die. The die holder is included in a clamp arm or slide block. The die holder is restricted from axial movement by at least a first complete or partial conical surface and possibly by a second complete or partial conical surface that directly or indirectly bears against the clamp arm or the slide block.
