How to solve your vibration problem.
What is your current situation
If the plant is equipped with on-line vibration equipment to measure the vibrations of the shaft line, the operator is able to see the actual values in the DCS. If the overall levels will rise above a certain alarm level, lets say 120 microns peak to peak, the operator then starts looking at the vibration trend diagram. But then? What can he do?
Several ways to solve your current situation
The easiest way to proceed is to call the local vibration expert. If this local vibration expert only can see the overall values in the trend diagram then it will be hard for him to solve this vibration problem. If you don’t have a local vibration expert then you can call a specialized company like Advituro and ask assistance. The Advituro vibration expert will arrive at your plant and look also in the trend diagram of your DCS. Also he can not solve this vibration problem only with trend data.
Conclusion you need more than only vibration equipment that is able to send the overall values to your DCS.
The vibration expert at your site

The software of this vibration monitoring equipment is able to show in different plots the vibration details, like the main frequency from the spectrum plot, half and full. Or the shaft center line with the DC values of your proximity probes. At last, did you already installed a phase reference measurement on your shaft line? Then the Advituro vibration expert is also able to see orbit plots and polar plots or bode plots. The measurement of the once per revolution signal is a very important measurement and enlarge the analyzing with 80% till 100%.
Connect Advituro to your vibration PC
It can be scary because you think that your unit is visible to everybody in the world.

2. Enable a VPN connection to your vibration computer. This enables you to ask an external vibration expert to look in your vibration data
3. Hire a certified vibration expert to analyze. This will certain you that the specialist you are calling with has the theoretical and practical experience to solve your vibration problem.
4. Buy a remote vibration condition monitoring contract for your plant.
Enables you a pre-warning in most cases before your operators are alarmed by the DCS.The result will be no vibration problems anymore that will give you a headache. Improvement of the availability and reliability of your plant

Ad Hoc Vibration Measurements
When there is a sudden change in vibrations and perhaps alarm levels are triggered, Advituro can help you. We install our mobile monitoring system and analyze the vibration data. Advituro can rely on more than 25 years of experience with vibration analysis in power plants.
Before a major overhaul make sure you know the vibration behavior of your machine. Check this again after the major overhaul to make sure that works have been done according to contract.
Remote Vibration Monitoring, use it!
Blade Vibration Monitoring
The rapid changing Energy market puts power plant owners under pressure. Where ones the assets were bought for base load operation now days a lot of flexibility is required. Is your steam turbine up to the job? To get a better understanding of the vibration behavior of the last stage blades Blade Vibration Monitoring is the solution. By connecting the monitoring system to the already installed proximity probes it is possible to see the blade vibrations of the L0 or L-1 blades. This makes it possible to see in what operating window blades vibrate and can resolve in:
Make your asset more flexible!
Generator end-windings experience mechanical vibration during operation and the level of these vibrations are an indication for the owner if the generator is aging severely. High vibrations can lead to loosening of entire end-winding support system, wear of insulation material, rupture of coil and fatigue cracking of conductors. All of which require extensive out-of service repairs. The end-winding vibrations measurements will inform the owner much earlier and he can plan an inspection during his normal outage schedule if necessary.
