NEW YORK -- Alcoa has signed a development agreement with Cameron to commercialize aluminum drilling riser systems for offshore oil and gas exploration and development.

The lightweight aluminum riser system will extend the capability of existing drilling vessels, allowing exploration in deeper depths of 20% or more versus conventional steel risers, the companies say. Welded aluminum risers weigh nearly 40% less than steel risers and require up to 40% less buoyancy material for similar depths. According to the companies, aluminum risers are easier and less expensive to transport, store, and deploy.

Last week, Alcoa agreed to purchase Noble Corporation’s intellectual property pertaining to welded aluminum risers, allowing the company to form this cooperative partnership with Cameron.

“The aluminum drilling riser system is an innovation that could significantly change deepwater oil and gas drilling,” says Mary Zappone, president of Alcoa Oil & Gas. “This partnership with Cameron, one of the most accomplished leaders in drilling and production systems, validates the lightweight aluminum riser system as a viable product.”
