The Panama-convenience flagged vessel was designed and outfitted to operate in harsh environments. The rig was 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 an 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 was 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. In January 2016, it was decided to scrap the rig, and after a period berthed at Invergordon, Scotland, it departed, under tow, for Aliaga, Turkey on 19 April 2016.
