  • Patent number: 7509722
    Abstract: The present invention generally relates to a method and apparatus for connecting a first tubular with a second tubular. The apparatus includes a gripping member for engaging the first tubular and a conveying member for positioning the gripping member. The apparatus also includes a spinner for rotating the first tubular. In one embodiment, the spinner includes a motor and one or more rotational members for engaging the first tubular. In another embodiment, the apparatus includes a rotation counting member biased against the first tubular. In another aspect, the present invention provides a method of connecting a first tubular to second tubular. The method includes engaging the first tubular using a gripping member connected to a conveying member and positioning the gripping member to align the first tubular with the second tubular. Thereafter, the first tubular is engaged with the second tubular, and the first tubular is rotated relative to the second tubular using the gripping member.

  • Patent number: 7043814
    Abstract: An apparatus is provided with position sensors. When the apparatus has moved one tubular into alignment with another tubular a button on a remote control console is pressed to memorize the position. After the next tubular has been gripped by the apparatus a “recall” button is pressed and the apparatus automatically moves the next tubular to the memorized position. This saves vital seconds in joining tubulars and also reduces the likelihood of threads being damaged due to misalignment of the tubulars.

  • Publication number: 20040035587
    Abstract: An apparatus is provided with position sensors. When the apparatus has moved one tubular into alignment with another tubular a button on a remote control console is pressed to memorise the position. After the next tubular has been gripped by the apparatus a “recall” button is pressed and the apparatus automatically moves the next tubular to the memorised position. This saves vital seconds in joining tubulars and also reduces the likelihood of threads being damaged due to misalignment of the tubulars.

  • Patent number: 6612184
    Abstract: There is provided a method of testing a joint formed by bonding of two tubulars, which method comprises the steps of holding a first tubular; applying a force to displace a second tubular relative to the first tubular; and removing the force. The final position of the second tubular is then compared with the position which it occupied prior to the application of the force by means of a sensor mounted remotely from the second tubular.
