AVR is specialized in processing various types of residual waste and converting this waste into energy and raw materials for households and businesses. In their plant in the Botlek (Rotterdam) they operate a steam turbine which drives a generator. AVR used a Bently Nevada BN3500 overspeed detection system (ODS) to detect overspeed situations and zero-speed.  

When an overspeed situation occurs the system should trip the steam turbine to prevent potential damage and dangerous situations. Zero-speed was monitored to prevent the turning gear from starting soon. The turning gear can only be started, when the rotor has come to a complete stop, as this could otherwise damage the turning gear.
