US-based Doris and Norway’s Sevan Marine have performed research and model scale testing of the latter’s cylindrical hull for application in the Gulf of Mexico.
The research has been carried out as part of a programme organised by nonprofit consortium Research Partnership to Secure Energy for America (RPSEA).
Tests were carried out at the Offshore Technology Research Center (OTRC) at Texas A&M University in the US.
The research confirmed that the Sevan Marine’s design enabled the application of steel catenary risers (SCR) and permanent mooring, even during adverse conditions.
Further tests are expected to enhance Sevan Marine’s SCR concept.
The projects secured funding through the Ultra-Deepwater and Unconventional Natural Gas and Other Petroleum Resources Research and Development Program, which is authorised by the Energy Policy Act of 2005.
The programme aims to to assess and reduce risk, and improve the environmental sustainability of oil and gas exploration and production activities.
RPSEA comprises more than 180 members, including 24 of the country’s research universities, five national laboratories, and large and small energy producers and consumers.
