Abstract
A pipe handling method to move the tubulars used from a horizontal position on a piperack adjacent the well bore to a vertical position over the wall centre or a mousehole which utilizes bicep and forearm assemblies and a gripper head for attachment to a tubular. The path of the tubular being moved is close to the conventional path of the tubular utilizing known cable transfer techniques so as to allow access to the drill floor through the V-door of the drill rig.
