Do you think gas turbine require water contamination routine tests in its oil analysis?

yes I think so.

Water may enter in several different ways.
- leaks in cooling systems (oil coolers)
- wash offs / maintenance
- condens from variations in temperature
- Enviroment?

Dear Duarte

Acording to ASTM D-4378-03, you shouldn't run water content analysis of the oil.

However, as you know water in the oil up of 100 ppm is in the emulsified form. When you have this high value, you could have problems with the lubrication regime, the oil degradation, and equipment rust.

I think that water content analysis isn't a expensive test, and the result gives you more data for your predictive program.

In some cases you'll find water in Gas Turbines (5-7% of the cases according our experiencies). This water comes from rain, enviroments (Off Shore Platforms), etc.

I hope these comments help you.

What sort of oil are you suing inthe turbine
If its a synthetic polyol ester then yes i would measure the water content.
Static corrosion caused by synthetic oil hydrolysis can be very costly.
If its a mineral oil then only if you use a water heat exchanger or can have bulk water enter the system.
