Abstract:
A cableway transport system for moving tubulars between a supply of tubulars and a rig mast implements a gondola suspended and movable along load cables. The gondola is fit with grippers for carrying tubulars between the rack and mast. The gondola has a first landing coupler which is received and releasably couples to a second landing coupler on the mast for forming a landing connection. The landing connection enables rotation of the gondola to align the carried tubular with the wellhead. The grippers can be individually actuable to allow finer alignment of the tubular above the wellhead.
