Sevan Marine has been an active developer of a new type of FPSOs which are drawing a considerable amount of attention from the industry – the innovative concept of cylinder-shaped platforms.

The company was present at BIS Group's Advanced FPSO Forum in London this month to talk about the advantages of cylindrical vessels over ship-shaped vessels and new concepts under development for its range of FPSOs.

“We are now developing new concepts for the cylindrical FPSO range," Frederik Major, a naval architect and vice president of business development and R&D at Sevan Marine said. "These include an icebreaking unit; we have also developed a concept for operating with steel catenary risers; an FLNG concept; and a logistic hub where crew can be transported to the different platforms via sea and air.” The new concepts also include a platform bridge link to be located close to the wellhead platform and a floating power plant.

There are currently 11 projects on cylindrical hulls provided by Sevan Marine, in addition to seven FPSOs and four drilling units. Sevan Marine’s first cylindrical FPSO, the Piranema Spirit – start-up in 2007 – is now operating for Petrobras on the Piranema field in the deep waters of the Brazilian state of Sergipe.

The vessel, which floats on a very shallow draft (as little as five metres) and is therefore an easy unit to bring to shore, is interconnected to six wells and installed at a water depth of 1,100 m. As for specifications.

The Sevan 1000 cylindrical FPSO has an oil production capacity of 100,000 barrels per day, a gas production of 3.9 million standard cubic meters per day and an oil storage capacity of 1 million barrels.
