Bearings and condition monitoring specialist Schaeffler (UK) Ltd has supplied five online condition monitoring systems to wind farm developer and operator Fred.Olsen Renewables (FOR). A further 20 condition monitoring systems from Schaeffler are expected to be installed later this year on the remaining turbines.
In May 2012, FOR installed five FAG WiPro s condition monitoring systems from Schaeffler on five wind turbines at the Crystal Rig wind farm in Scotland. These systems continuously monitor the condition of the main rotor bearings, gearbox and generators, with Schaeffler UK also providing remote monitoring services on a 24/7 basis.
Crystal Rig wind farm is located on the Lammermuir Hills, approximately 40km east of Edinburgh in the Scottish Borders. When Crystal Rig wind farm commenced operations in October 2003, it was the largest onshore wind farm in Scotland, with a rated output of 50MW. The hub heights of the Phase 1 wind turbines are 60m with a rotor diameter of 80m.
In phase 2, a further five wind turbines were installed at Crystal Rig, bringing the total number of turbines to 25, generating a total capacity of 62.5MW from May 2007.
