Insight into: Renewables: Offshore Wind
One of the most important technical challenges being faced by many European offshore wind farm developers first came to light in April 2010, when a design fault in grouting used to secure wind turbines to their monopiles or towers was discovered.
Due to this design fault, the grout injected during the installation of the offshore wind farms started breaking up, which caused the turbines to move on their monopile foundations.
A solution was engineered to remedy the failing structures allowing ENGIE Fabricom to successfully execute 54 Phase 1 wind turbine repairs within a single campaign. This included installation of new jacking frames, bearings, welding, NDT, painting, J-tube inspection and installation of ventilation systems and supply of all constructed components.
