MOSES Wind Turbine

Deliver safe, cost-effective floating offshore wind farm structures?

MOSES Wind Turbine is advanced simulation software for the design and analysis of floating offshore wind turbine platforms. It enables detailed 3D modeling of hydrodynamic and aerodynamic interactions accounting for wave, wind, current, and mechanical loads. The software integrates with external wind turbine solvers to apply realistic load cases and supports mooring system analysis to evaluate platform stability under dynamic, real-world environmental conditions. Optimize your designs for safety, performance, and compliance with international offshore standards, to deliver efficient and reliable floating offshore wind farms.
