Discoverer Enterprise

Discoverer Enterprise is a fifth generation deepwater double hulled dynamically positioned drillship (Astano FPSO design) owned and operated by Transocean Offshore Deepwater Drilling Inc., capable of operating in moderate environments and water depths up to 3,049 m (10,000 ft) using an 18.75 in (47.6 cm), 15,000 psi blowout preventer (BOP), and a 21 in (53 cm) outside diameter (OD) marine riser.

On June 3, 2010, several weeks after the explosion of Deepwater Horizon, Discoverer Enterprise was used to collect oil and gas from the damaged subsea wellhead by lowering a cap connected via a drilling riser over the release, and collecting oil and gas.
