Strategy to support R&D projects and technology development to make
the MRE economically viable• By using large scale numerical and testing facilities
• Validation of numerical methods and model tests vs results in real conditions
Numerical modelling
Tank Testing
In situ monitoring and survey
From the first idea To demonstration in real conditions
