Abstract: A method and apparatus for handling tubulars is provided. In one aspect, th e present invention provides a spinner having a first arm having a first rolle r and a second arm having a second roller, the first arm and the second arm simultaneously adjustable to retain the tubular. The apparatus also includes a third roller capable of urging the tubular against the first and second rollers, wherein at least one of the first, second, and third rollers is actuatable to rotate the tubular. In one embodiment, the spinner further comprises a fluid operated cylinder for adjusting the first arm and the second arm. The arms are adjusted by actuating the cylinder extend or retract the first arm and the second arm. In another embodiment, t he first arm and the second arm are coupled together and may retract or extend simultaneously. In another embodiment still, the arms may include a cam surface to move the rollers closer together to adjust to the size of the tubular being retained. In another embodiment still, at least one of the rollers is equipped with a motor to supply torque to the tubular. In another aspect, the spinner is used in combination with a tong assembly to make up or break up a tubular connection.

Abstract: An apparatus for connecting tubulars comprises tongs for gripping the tubulars, having openings which can be aligned to allow tubulars to enter the tongs, and a detection apparatus for detecting the location of a joint between the tubulars. The detection apparatus comprises a set of keys disposed along an axis substantially parallel to the axis of the tubulars, the keys being individually displaceable on contact with the tubulars as the tubulars enter the tongs through the openings. The detection apparatus further comprises a set of sensor means, each arranged to detect displacement of a corresponding key. The position of the joint can then be determined from the displacement of the keys.
