What we do
Our solutions
Sevan Cylindrical Hull
The Sevan cylindrical hull is designed for geostationary mooring and delivers excellent motion performance, even in harsh environments—while eliminating the need for complex, maintenance‑intensive, and cost‑driving turret and swivel systems.
Its double‑symmetric hull geometry offers unmatched scalability and flexibility, allowing the design to be tailored to specific client and project requirements. A dedicated sector provides generous space for risers and cables, safely accommodated and well protected through I‑tubes located within the ballast tanks.
The performance and robustness of the Sevan cylindrical hull are proven through more than 1,000 model-scale tests, 12 units built, and decades of accumulated operational experience.

Sevan Semi-Submersible
The Sevan semi-submersible features a double-symmetric main hull comprising a ring pontoon and four vertical, octagonal columns. The pontoons are constructed with longitudinal stiffeners and transverse frames to ensure optimal constructability and structural efficiency. To reduce weight and simplify construction, the pontoons are designed without access trunks.
The Sevan semi-submersible is engineered for optimal efficiency, minimizing cost and production time while maintaining a high level of scalability and flexibility to meet specific client and project requirements.Its double‑symmetric hull geometry offers unmatched scalability and flexibility, allowing the design to be tailored to specific client and project requirements. A dedicated sector provides generous space for risers and cables, safely accommodated and well protected through I‑tubes located within the ballast tanks.
To further reduce construction time and cost, the main hull can be fabricated in blocks, while the topside module is designed for single-lift integration. This enables an efficient fabrication, construction, and topside integration process.
