Top drive casing running system

An adaptor that attaches to the top drive eliminating floor tongs and manual handling of casing using the power and rotation from the top drive. When connected to the top of the casing it is used to spin in and make-up the connection of the casing accurately. This system may also include a casing fill-up and/or casing circulation function. A floor based method of holding adequate back up or a slip system is needed to react to the torque in the string as the top drive is made up to the upper casing joint.
