Offshore industry solutions provider Sevan Marine has secured approval from the American Bereau of Shipping (ABS) for the cylindrical floating liquified natural gas (FLNG) design concept.

ABS granted Norway-based Sevan Marine approval in principle (AIP) for the offshore production, storage and transfer of liquified natural gas (LNG), liquified petroleum gas (LPG) and condensate.

"We are proud to have been granted AIP for our unique design concept, which we believe will introduce a better option for producing, storing and offloading LNG in challenging operating areas."

The concept is based on the circular and geostationary Sevan floating, production, storage and offloading (FPSO) design, which is being used in the Norwegian and Central UK North Sea, as well as offshore Brazil.

The design is under construction as the first application of an FPSO unit to be deployed in the Barents Sea.

The Sevan FLNG production unit will feature a cylindrical hull, which will have the ability to operate in water depths of more than 3,000m and in harsh environments, as well as extreme cyclonic situations.

Sevan Marine said the unit design is based on environmental load calculations for a 100-year return storm in the Barents Sea.

The FLNG unit’s axio-symetric hull shape, similar to the Sevan FPSOs, will enable high-capacity storage of LNG and allow for deck loads and tolerance for weather spreading. It removes the requirement to weathervane in rough seas.

Sevan Marine chief operating officer Lars Ødeskaug, who is responsible for Sevan’s LNG efforts said: "High availability, inherent safety and simple operation should be the main criteria when selecting technology offshore.

"Sevan’s cylindrical FLNG solution meets these criteria at an attractive cost. We are proud to have been granted AIP for our unique design concept, which we believe will introduce a better option for producing, storing and offloading LNG in challenging operating areas."

The unit can be designed to have gas processing and liquefaction of up to four million tonnes per annum (MTPA) and store about 240,000m³ of LNG and 36,000m³ of condensate.
