Saitec Offshore concrete technology for floating offshore wind, designed for deep waters and validated at full scale through the DemoSATH project.
SATH starts from a geometry designed to reduce construction complexity and support industrialization.
SATH brings together 10 years of technical learning across testing, simulation and open-sea experience.
The SATH design and its mooring system allow the platform to maintain stability, reduce loads and orient naturally with wind and waves.
The design is aimed at commercial floating wind farms, with local fabrication and adaptation to different sites.

A competitive concrete floating foundation for offshore wind turbines
SATH combines a twin-hull concrete floating platform with a single point mooring system, designed to orient naturally with wind and waves. Its geometry supports industrialization, reduces dependence on deep-draft ports and enables locally built, scalable solutions for floating offshore wind anywhere in the world.
Maximum wave withstood by DemoSATH
DemoSATH remained stable through storms with waves of 13.12 metres.
Wind gusts withstood
The platform remained stable under gusts of up to 144 km/h.
Full-scale DemoSATH at sea
A grid-connected 2 MW prototype validating the technology in real conditions.
Commercial design in development
Scalable to commercial 15-20 MW wind turbines.
Hover each metric for more detail
Design choices that reduce cost, emissions and installation complexity.
Single point mooring allows the platform to orient naturally with wind and waves, reducing loads on the mooring system.
Concrete has a significantly lower carbon footprint than the equivalent steel solution.
Greater durability and fatigue resistance, helping reduce manufacturing, operation and maintenance costs.
A local-content enabler that can be built close to each project, supporting regional supply chains and jobs.
Single point mooring allows SATH to orient naturally with metocean conditions, improving its offshore response and reducing loads on the mooring system.
