Conductor torquing system

An apparatus for making up large diameter conductor casing having threaded connections comprising:

• a lower chain vise adapted to grin a first joint of conductor casing to prevent rotation thereof,
• a plurality of movable arms operable to apply a retaining force to a second joint of conductor casing to maintain the second joint of conductor casing in rotational contact with one or more drive wheels on a spinner means,
• the spinner means operable to rotationally make-up a threaded connection connecting the second joint of conductor casing to the first joint of conductor casing to an initial make-up torque, and
• an upper chain vise adapted to grip the second joint of conductor casing and operable to apply a final make-up torque to the threaded connection connecting the second joint of conductor casing to the first joint of conductor casing;
• wherein the lengths of the movable arms may be telescopically extended to close about the second joint of conductor casing.

An apparatus for making up jointed pipe with threaded connections comprising:

• a first chain vise adapted to grip a first joint of pipe to prevent rotation thereof,
• a spinner means having one or more drive wheels operable to rotationally make-up a threaded connection between a second joint of pipe and the first joint of pipe to an initial make-up torque,
• one or more extendable arms operable to apply a retaining force to the second joint of pipe to maintain the second joint of pipe in rotational contact with the drive wheels of the spinner means, and
• a second chain vise adapted to grip the second joint of pipe and operable to apply a final make-up torque to the threaded connection.
