Transocean John Shaw is a semi-submersible drilling rig designed by Friede & Goldman as a self-propelled modified & enhanced pacesetter, built and delivered in 1982 by Mitsui Engineering & Shipbuilding Ltd. in Japan.

The Panama-convenience flagged vessel was designed and outfitted to operate in harsh environments and is currently located in the North Sea off Scotland. The rig is capable of operations at water depths up to 1,800 ft (550 m) and drilling down to approximately 25,000 ft (7,600 m) using a 18.77 in (47.7 cm), 10,000 PSI blowout preventer (BOP), and a 21 in (53 cm) outside diameter (OD) marine riser.[2]

The rig is named after John S. Shaw, former chairman of Birmingham, Alabama-based Sonat Inc. Sonat spun off its offshore division as Sonat Offshore in 1993, and it changed its name to Transocean in 1996.
