| 20120111155 | DEVICE AND METHOD FOR ROTATION OF TORQUE TONG - A device for rotation of a torque tong with at least two diametrically opposite circular arc-shaped segments and gripping devices for holding a pipe substantially perpendicularly to the torque tong's radial plane. To each segment and in abutment thereto there is provided at least one elongated flexible drive element operatively connected to support units and devices for movement of the respective drive element so that the torque tong is rotated in the radial plane. Each drive element is attached at first and second ends to respective securing portions and includes an engagement portion in engagement with and/or abutment against a segment. Rotation of the torque tong is implemented by performing a rectilinear movement of a first of said movement elements, and simultaneously implementing a rectilinear movement of the second of said movement elements in the opposite direction to and substantially parallel to the movement of the first movement element. | 05-10-2012 |
| 20120111154 | CENTRING MEANS IN A ROTARY TONG - The invention relates to a pipe clamping device comprising a housing which has a tubular centre in which a pipe is to be positioned. The pipe clamping device comprises at least three gripping devices for synchronous movement in towards the pipe. Each gripping device is disposed with a direction of movement in towards the tubular centre, where each gripping device is arranged in order, in contact with the pipe, to provide a holding force. The pipe clamping device is provided with elongate flexible transmission elements, each of the elongate flexible transmission elements being attached to one of the gripping devices and running in contact with at least one support means to attachment to each of the other gripping devices. Upon movement of at least one of the gripping device, this movement is transmitted to at least one of the other gripping device by the associated elongate transmission element. The invention also comprises a pipe clamping device in which there is used at least two gripping devices and a torque tong, of which the pipe clamping device is a part. | 05-10-2012 |
| 20110087474 | SIMULATOR SYSTEM AND METHOD - A simulating system comprises an input device, intended to be operated by an operator, a simulator arrangement, and a display. The simulator arrangement is configured to read a signal representing an operation of the input device, and to simulate equipment using said input signal and pre-stored equipment characteristics. The equipment may be drilling equipment for use in offshore oil/gas exploration. The system results in a visual representation of the equipment, manipulated by the input device. The simulator arrangement comprises an equipment controller, connected to an environment simulator that provides the visual representation of the equipment. The environment simulator is connected to an object database comprising equipment objects. | 04-14-2011 |
