Learn more about Saitec Offshore Technologies
Saitec Offshore Technologies was created as a specialist company to develop SATH, Swinging Around Twin Hull, and bring Saitec's experience in civil engineering, structures and renewables into the floating offshore wind market.
Values
Technical knowledge in service of floating offshore wind
Proven innovation
Advancing through R&D, testing, real data and certification to consolidate the technology before commercial deployment.
Sustainable impact
Supporting the energy transition with a competitive, industrializable solution that operates responsibly in its environment.
A company created to bring Saitec's knowledge into the development of floating offshore wind.
Saitec knowledge driving floating offshore wind.
Saitec's experience in structural calculation, civil works and renewables moves offshore with a clear objective: developing a competitive and industrializable floating solution to help deploy offshore wind where fixed-bottom foundations are not the answer.
SATH development is built on data, testing and operational learning. That knowledge helps mature the solution, reduce uncertainty and prepare its application in larger-scale projects, with a vision connected to ports, supply chain and operation.
SATH brings Saitec's structural, civil and renewable expertise offshore. Its development combines data, testing and operational learning to mature the technology before scaling.
Why offshore wind
Wind potential needs technology able to operate in real conditions.
Floating wind opens access to deeper waters. Deployment requires engineering, ports, fabrication and real-sea operation to work together.
92.5GW
Growing global scale
Installed by the end of 2025. 9.3 GW connected during the year, with offshore wind present in 19 markets.
GWEC · Report 2026269MW
Floating wind under construction
Global capacity under construction at the end of 2025, across four projects in China, France and Japan.
WFO · Report 2025 (March 2026)Full context and sources
Offshore wind combines energy transition, industrial scale and activity linked to ports, manufacturing, logistics and operation. Floating wind expands that potential into deeper-water locations, but adds a decisive condition: structure, mooring, dynamics, installation, maintenance and certification must work as one system.
Growing global scale
GWEC reports 92.5 GW of global offshore wind installed by the end of 2025, after 9.3 GW connected during the year and presence across 19 markets. The opportunity no longer depends only on resource: it requires industrial execution, ports, supply chain and real-sea operation.

WFO records 269 MW of floating offshore wind under construction at the end of 2025: Hainan PFS-1 Wanning Southeast (192 MW), EFGL (30 MW), EolMed (30 MW) and Goto (17 MW). Its criterion requires at least one floater in final assembly. This is capacity under construction, not installed or operational capacity; it is not directly comparable with GWEC's total installations.

A decade of testing, fabrication and operation to take SATH from initial development to validation in port and in the open sea.
Saitec Offshore Technologies is created
The company is created to develop SATH and bring Saitec's experience into the floating offshore wind market.
Testing and international engagement
SATH design progresses through testing and simulations that reproduce the effects of wind and waves. The results help verify calculations and refine the platform before taking it to sea. In parallel, SOT shares its progress at international industry forums.
From design to construction
SATH takes shape at the Port of Bilbao. Fabrication, assembly and testing bring engineering into practice, preparing DemoSATH for installation offshore.
DemoSATH is installed at BiMEP
The 2 MW prototype operates in open sea off the Basque coast, connected to the grid and monitored as a floating laboratory.
Towards commercial deployment
Experience from testing and operation enables SATH to be adapted for higher-power wind turbines and supports progress towards serial production. Monitoring, biodiversity studies and new R&D programmes provide knowledge to take the next step.
Our team
A team prepared to approach floating wind from every angle.
SOT brings together structural and naval engineering, geotechnics, hydrodynamics, metocean, marine operations, industrialization, quality, safety, environment, R&D and business development. Floating technology needs teams able to connect design, execution, operation and continuous learning from early stages.

Quality, HSE and environmental management
Reliable technology demands quality, safety and responsibility.
In offshore projects, prevention is part of the work from the beginning and influences how assets are designed, fabricated, installed and operated.
Quality, HSE and environmental management help anticipate risks, protect people, coordinate suppliers and reduce impacts. It is a cross-functional discipline that accompanies the project from early decisions to open-sea operation.
Saitec Offshore Technologies has ISO 9001 and ISO 14001 management systems as part of its commitment to quality and environmental management.
