The Sevan Concept

The cylindrical Sevan concept is a flexible, turretless floating unit with a unique combination of in-hull storage capacity, deck weight capacity and favourable motion characteristics.

The concept can be tailored to a wide range of applications in benign and harsh environments, such as winter storms in the North Sea, cyclones in Australia or hurricanes in the Gulf of Mexico.
