Abstract
A horizontal offline stand building system includes a substantially horizontal, elongate catwalk having a frame and a stand lifting arm. The catwalk has a top surface adapted to receive at least two tubulars aligned coaxially along a linear path in a make-up channel on said top surface. The tubulars are threaded together to form preferably at least a triple pipe stand in the make-up channel. The completed stand is then transferred laterally to a delivery channel containing the stand lifting arm. The stand lifting arm is selectively actuable lifting arm for selectively elevating a rig end of a pipe stand from said top surface of the catwalk to the deck of a drilling rig, and then for supporting the mid and rear sections as the stand is hoisted from the delivery channel up the derrick of the drilling rig.
