Vibrations & Rotating Machinery

Analyzing, preventing, and alleviating vibration issues

Rotating machinery is often exposed to vibrations that can eventually cause damage. Unfortunately, vibration issues can go unnoticed for a very long time, acting as ‘hidden destroyers.’ Laborelec has extensive experience in analyzing vibrations. Consequently, we are able to provide effective assistance in preventing and alleviating related problems. A key tool in this service is Laborelec’s online Vibration Monitoring System (LVMS). We also use on-site measurements and/or rotor dynamics modelling to conduct plant-specific analyses.

Permanent and/or ad-hoc vibration management assistance

Laborelec supports power plants in detecting vibration issues and preventing and alleviating the resulting problems. We provide both permanent and ad-hoc assistance:

• Remote vibration monitoring. We can equip machines with LVMS, a tool focused on large rotating machinery such as turbine generators. LVMS is based on more than 1000 machine-years’-worth of monitoring experience and enables us to remotely monitor the equipment and quickly give advice to plant operators on the severity of a vibration problem and the possible corrective actions.
• On-site assistance. Within the scope of a vibration analysis, we also provide on-site assistance for vibration measurement campaigns. Our services can vary from balancing actions, to temporary follow-up with a mobile LVMS, to more complex tasks such as torsional vibration measurements or fast transient analysis.

Rotor dynamic modelling

In addition to our measurement-based diagnostic and remedial services, we also construct and validate rotor dynamics models of gas and steam turbine-driven shaft trains, which are then used in the root cause analysis of more complex problems.
