The rig’s design and capabilities include numerous features that increase operating efficiency.

Primary, are enhanced and redundant offline tubular stand building features and a 165-ton active heave compensating construction crane, allowing for the deployment of subsea production equipment without interference with ongoing drilling operations. The rig, which will be initially outfitted for drilling in water depths of up to 10,000 feet, will be equipped with dynamic positioning in compliance with DPS-3 certification; six-5.5 megawatt thrusters for enhanced station-keeping; expanded drilling fluids capacity; a 15,000-psi subsea well control system with six rams, upgradable to seven rams and/or a second BOP stack; burner boom for well testing; and living quarters for up to 200 personnel.
