Sevan Deepwater Technology

Sevan Deepwater Technology is a specialized marine engineering and design house. We innovate, design and execute cost effective offshore solutions. We pioneered the cylindrical hull as a cost effective alternative to traditional ship-shaped, turret moored designs. The innovative, geostationary design avoids the need for a costly turret while allowing for a larger number of risers and the flexibility for future tie-ins. With 12 units constructed and over 70 years of accumulated operational experience, the cylindrical hull is a proven and credible alternative to traditional offshore, floating designs. Sevan Deepwater Technology is a fully-owned subsidiary of Seatrium. For more information on Seatrium, please visit
