Abstract

A method of handling a short tubular on a drilling rig. The drilling rig includes a drill floor, a short tubular storage apparatus on which a short tubular is arranged, a vehicle which moves and transports the short tubular storage apparatus on the drill floor, and a tube handling apparatus having a base supported by the drill floor, an arm with a first end pivotally mounted on the base and a second end on which a pick up tool is mounted, and an actuator which pivots the arm relative to the base. The pick up tool holds the short tubular. The method includes using the vehicle to transport the short tubular storage apparatus to a location on the drill floor, and operating the actuator to move the pick up tool to engage the short tubular, to lift the short tubular, and to move the short tubular on the drill floor.
