Marine contractor Van Oord’s Aeolus wind turbine installation vessel (WTIV) is back on assignment at the Saint-Brieuc project off France, after being taken out of service following a hydraulic fluid leak that occurred while it was carrying out foundation installation work at the site.

Developer consortium Ailes Marines, led by Spanish utility Iberdrola, said “a complete review of the vessel's tools and equipment [as well as all of the work control and monitoring protocols had been reassessed” after some 100 litres of the lubricant was released into the Bay of Saint-Brieuc.
