Sevan Marine tests cylindrical hull for Gulf of Mexico

Offshore staff

ARENDAL, Norway – Under a program organized by the Research Partnership to Secure Energy for America (RPSEA), Doris Inc., the Offshore Technology Research Center (OTRC) at Texas A&M University, and Sevan Marine have carried out further research and model scale testing of Sevan Marine’s cylindrical hull for application in the ultra-deepwater in the Gulf of Mexico.

“The model tests at OTRC confirm the favorable motion characteristics of the Sevan Marine design, enabling the application of with steel catenary risers (SCR) and permanent mooring in even the harshest hurricane conditions,” Sevan Marine said, noting that further research and testing to bring its patented SCR concept to full potential is planned.

Funding for the projects is provided through the “Ultra-Deepwater and Unconventional Natural Gas and Other Petroleum Resources Research and Development Program,” authorized by the Energy Policy Act of 2005.

The program—funded from lease bonuses and royalties paid by industry to produce oil and gas on federal lands—is designed to assess and mitigate risk enhancing the environmental sustainability of oil and gas exploration and production activities. RPSEA is under contract with the US Department of Energy’s National Energy Technology Laboratory to administer three areas of research.
