One of our 2MW turbine generator bearings failed causing a critical failure of the generator, which resulted in the purchase and installation of a complete replacement generator. The cost of hiring a crane, the labour costs of a major component change team and 10 days of lost production when added to the cost of the new generator was a total of $208,700.

Shortly after this, we experienced the same failure on a further two of our turbines. We looked for a reason for these failures and a pattern started to appear. Each of these three generators had recently had their rotor cables replaced and as a part of procedure also their NDE bearing. The Moventas CMaS team were consulted and it was decided to fit CMaS to monitor all our turbines where generator rotor cables had been replaced.
