Five Ashtech ProFlex 500 GNSS receivers are helping guide the operations of the self-propelled jack-up vessel Bard Wind Lift I, the first construction vessel specially designed for installing offshore wind turbines, to build the first commercial wind farm in the German North Sea. The Ashtech GNSS receivers are used for every maneuver of Wind Lift I, including precisely positioning the vessel, assisting it to accurately jack itself up from the seabed on 233 ft long legs, and installing the foundation piles for the wind turbines. EIVA, the Danish provider of system solutions and services for marine survey, provided the positioning solution for Bard, the German designer, builder and operator of the offshore wind farm.
