GSF Development Driller II is a fifth generation, Vanuatu-flagged dynamic positioning semi-submersible ultra-deepwater drilling rig owned and operated by Transocean. The vessel is capable of drilling in water depths up to 7,500 ft (2,300 m) with drilling depth of 35,000 ft (11,000 m), upgradeable to 37,500 ft (11,400 m).[2]

Development Driller II was deployed in drilling a relief well on the Macondo Prospect to stop the massive oil spill caused by the explosion and subsequent loss of Deepwater Horizon.[4]
