Sevan Cylindrical Hull Technology:
Sevan Marine was established in 2001 based on the understanding of the significant benefits of a cylindrically shaped hull form for floating offshore applications.
Main driver for this specific hull form is the independence of directionality for waves, wind and current and consequently the ability to be moored in a fixed orientation even in the harshest environments.
Significant research including numerous scale model tests have resulted in a technology suitable for applications such as Floating Production, Storage and Offloading (FPSO) units and Mobile Offshore Drilling Units (MODU).
The Sevan hull is suitable for operation in water depths ranging from very shallow to ultra-deep both benign and harsh environments. Experience from the units in operation as well as a wide range of Comparable Model Testas well as for the toughest cyclonic conditions, have demonstrated the suitability for all environments..
