Shanghai: DNV is providing offshore classification services for Sevan Marine's extensive series of seven (7) offshore projects underway in China. Sevan's order book in China represents the single biggest offshore series undertaken to date in China. ''DNV has been with us since the beginning of Sevan Marine and we can say that we would not be in the position we are in today without our excellent cooperation with DNV,'' said Bjørn Egil Gustavsen, the project manager for the Sevan 650 Drilling Unit. Gerry Higgins, District Manager DNV Maritime, said, ''We are likewise very pleased to be working with Sevan Marine thanks to their business strategy, which is based on a Build-Own-Operate model that gives Sevan control over the value-creation chain. We believe that DNV is adding value to the project in a number of ways,''According to Sevan Marine, the cylindrical-shaped units represent a design breakthrough due to their simplicity and the fact that the design and construction can be repeated for various versions. Sevan Marine also says that the cylinder design is inherently stable compared to a structure which is shaped like a ship.DNV is conducting the complete verification of compliance with classification and statutory requirements for all units including; – Rules and Class Notations established (+OI, FPSO) – Main scantling approval – Global design analysis, incl. fatigue assessment – Approval in principal (AIP) – Class approval of construction drawingsThe first Sevan FPSO, the FPSO Sevan Piranema, completed the first offloading of oil this month from the Piranema field off the north-east coast of Brazil. The second – the China-built FPSO Sevan Hummingbird - is undergoing hook-up and commissioning at the Keppel Verolme shipyard in Rotterdam.The third - the FPSO Sevan Voyageur - left the Yantai Raffles Shipyard in China on 6 November and is on its way to the Keppel Verolme shipyard in the Netherlands for topside hook-up and commissioning. This unit will be installed on the Shelley field in the central UK North Sea in 2008.The Sevan 300 no. 4 hull, the Sevan 300 no. 5 and the Sevan 650 no. 1 are being built and having engineering work carried out on them at the Hantong Shipyard in China.In addition to these production units under construction at Hantong, DNV is also classing a deepwater drilling unit that Sevan Marine has ordered from COSCO Nantong.The Sevan Driller contract is for a drilling unit based on the Sevan 650 FPSO design. The whole project is scheduled for delivery to the client in 2009. The Sevan rig, which has an oil storage capacity of 150,000 barrels, will be able to drill wells of up to 40,000 feet deep at water depths of up to 10,000 feet. It will be deployed by Petrobras America Inc. in the Gulf of Mexico.''Based on the success and delivery of the first unit, we look forward to working with Sevan Marine on various additional Sevan units, which may be of different sizes and types,'' concluded Gerry Higgins, District Manager DNV Maritime. To summarise: In total, Sevan Marine has ordered five Sevan 300 FPSOs, the Sevan 650 driller and a Sevan 650 FPSO. The Sevan 300 FPSO has a displacement of 50,500 tons and a storage capacity of 300,000 barrels, while the Sevan 650 FPSO has a displacement of 110,000 tons and a storage capacity of 650,000 barrels.
