Until recently, most aspects of tubular handling and running preparation have been carried out on the rig floor offshore, a process that requires significant manual handling. Typically, tubulars were shipped to the rig and laid out on pipe racks while processes such as cleaning, tallying, thread inspection and drifting were carried out off line by the rig crew, before the pipe could be run in the hole. The number of personnel required to manually carry out these operations on a rig deck of limited space introduced significant risks to safety and efficiency.
