Frequently Asked Questions
How often should vibration measurements be performed?

For critical rotating equipment, annual measurements are recommended as a minimum. High-duty machinery may benefit from quarterly or monthly monitoring.

Can vibration measurements prevent machinery failures?

Yes. Trending vibration levels helps identify developing faults before they result in major failures or unplanned downtime.

Is the service performed onboard?

Yes. Our engineers perform all measurements onboard while the vessel is in port or during scheduled maintenance periods.

Do you provide recommendations after the inspection?

Yes. Every inspection includes analysis, findings, and practical maintenance recommendations based on the measured vibration data.
