Vibration Analysis Services

Vibration measurements are an excellent tool for a single condition measurement or for Trouble Shooting a sudden problem, but is also suitable for periodic Condition Monitoring of your machinery assets. 

During a typical vibration survey, an accelerometer or other vibration transducer is manually placed on several locations on the machine, usually directly on or in the near vicinity of the bearings. Vibration and rotational speed parameters are then measured while the machine is running normally. After acquiring reliable vibration data we begin the real specialism of interpreting the measurement and analysing the cause of a defect.

Interpretation analysis and recommendation requires specialised training, knowledge and experience. With Van Geffen Reliability, you will find every specialist possesses this knowledge and experience, all their interpretations and analysis are based on years of experience to provide you with a quick and reliable solution.

Vibration Analysis is the most frequently deployed technology on the market today and enables you to take maintenance action before a failure in service brings your plant to a halt. Our vibration analysis services can be used can be used for various purposes:

• Condition Monitoring
• Health Check/Pre-Docking inspections/Pre-Shut down inspections
• Troubleshooting
• FAT / Factory Acceptance Testing
• SAT / Site or Sea Acceptance Testing
• HAR / Harbour Acceptance Testing
• Witness Testing

Analysing and interpreting measurement data requires specialist knowledge. It requires understanding of machines, their construction and behaviour, as well as experience to relate the (vibration) signals to that knowledge. Years of experience and the highest possible specialisation for performing vibration measurements and analyses (up to ISO-18436-2 level III) makes Van Geffen Reliability the ideal partner for performing vibration analyses.

The field of application of vibration analysis is broad, whereby we make a clear distinction between vibration measurements:

• Rotating machinery
• Reciprocating machinery
• Static equipment

These measurements are further broken down into:

• Lateral vibration analysis
• Rotor dynamics
• Torsional vibration analysis (TVA)
• Flow-Induced vibration analysis (FIV)
• Acoustic-Induced vibration analysis (AIV)

We use different methods for vibration measurements and analyses.

(Semi) Continuous:

With this method, data is continuously generated by the vibration monitoring system and can be read locally or remotely. Van Geffen Reliability then analyses these data with a pre-agreed interval, or when deviations occur.

Periodic:

With this method, data acquisition takes place at a fixed interval by means of portable measuring systems/data collectors. Vibration data can then be analysed locally or remotely by van Geffen Reliability.

Remote:

With this method, the vibration data is continuously collected via the van Geffen Reliability cloud, after which it is analysed remotely by the specialists of Van Geffen Reliability.

Independently of the options described above, the physical performance of the measurements can partly be performed by the end user himself.

If no vibration monitoring system is present, van Geffen Reliability has access to various data collectors (2 and 4 channel) and advanced multi-channel measurement systems (8, 24 or 32 channel) for periodic, temporary or even permanent measurements.

We can perform vibration analysis anytime and anywhere. Our service is brand independent, which means that our specialists carry out measurements and analyses on all vibration monitoring systems and machines and equipment. We specialise in performing and analysing vibration measurements for industrial rotating and reciprocating machinery:

• Gas turbines
• Steam turbines
• Reciprocating/centrifugal Pumps
• Fans
• Gear boxes
• Reciprocating/centrifugal/screw Compressors
• Mixers
• Rollers
• Diesel/Gas Engines

And for static equipment

• Mainline piping
• Small-bore connections (SBC)
• Foundations
• Structures
• Ship hull
