Sevan's Cylindrical Hull Technology: 25 Years of IP & Proven Track Record Defining Next-Gen Offshore Floating Platforms
On March 12, 2026, Sevan Deepwater Technology AS (Sevan DWT) unveiled a detailed overview of its proprietary cylindrical hull technology, highlighting its 25-year intellectual property moat, field-proven performance, and strategic value in the competitive global offshore engineering market. Integrated with maritime giant Seatrium, this mature technology delivers low-risk, high-certainty solutions for both traditional oil & gas and emerging offshore energy projects.
At its core, Sevan's cylindrical hull technology is safeguarded by a comprehensive global patent portfolio, protecting key geometric features, functional principles, and exclusive commercial rights. This robust IP layout provides operators with full flexibility across asset operation, retrofit, and redeployment, with unrivaled technical security throughout the project lifecycle. Beyond theoretical design, the technology boasts a remarkable track record: 12 cylindrical units delivered worldwide over two decades, deployed for offshore production, drilling, and accommodation platforms across diverse sea conditions.
Following a strategic integration journey, from Sevan Marine to SembCorp Marine, then merging into Seatrium, Sevan was rebranded as Sevan Deepwater Technology in October 2024, operating as an independent tech entity within the Seatrium Group while retaining core IP and engineering expertise. This integration unlocks powerful synergy between Sevan's patented designs and Seatrium's global shipyards, supply chain, and EPC capabilities, creating a one-stop, single-responsibility delivery model.
The technology drastically cuts lifecycle risks, reduces engineering costs, and simplifies recertification for asset redeployment, critical advantages in today's fast-evolving offshore market. Expanding beyond oil & gas, Sevan's cylindrical hull is targeting carbon capture, floating wind, and offshore power generation. Its SWACH floating wind foundation design secured DNV AiP in November 2024, extending the field-proven platform to the energy transition sector.
