The DP-3 compliant, dynamically-positioned drillships will be equipped with retractable thrusters, dual-activity capability, five mud pumps, dual mud systems and a maximum hook-load capacity of 1,250 tons. Each will be equipped with a seven-ram BOP incorporating full acoustic backup control and storage and handling facilities for a second BOP. The drillships feature hull integration with below-deck riser storage, four million pounds riser tensioning, main load path active-heave drawworks with crown-mounted compensation, three 100-ton knuckle boom cranes, an active-heave 165-ton crane for simultaneous deployment of subsea equipment, a variable deck load capacity of 20,000 tons and accommodations for 210 personnel.
Matt Ralls, president and CEO, said, "Our long-stated strategy has been to focus on and diversify our offshore drilling business, and we are excited to take this first step into the ultra-deepwater sector. This investment will expand the breadth of Rowan's drilling services and enable us to address significant market and customer opportunities in the deepwater arena."
