Service interval & engine life extension

The use of condition based maintenance strategies will extend the interval between two services extending the total lifetime of the gas turbine.

New services such as VBR’s DECIDE will enable the shift from corrective maintenance to preventive & predictive maintenance.

Looking for increased production & cost reduction

Gas turbine operators are striving for opportunities to extend the intervals between maintenance service and prolongue the life of their power plants. Extending service intervals is a highly effective way to defer maintenance investment and reduce maintenance costs.

Sustainable maintenance improvement

VBR Turbine Partners is focused on systematic operation & maintenance improvement for GE LM gas turbines. In order to improve reliability, availability and maintainability in the long term, VBR’s aim is to shift from re-active corrective maintenance to pro-active preventive & predictive maintenance. This approach helps to prevent unnecessary disruptions to production and thus the related costs and delays. This approach provides optimization of long-term maintenance planning and an associated reduction of maintenance costs. Achieving this it is important to proactively monitor the health condition of a gas turbine.

Condition monitoring

With VBR’s unique DECIDE remote maintenance support we are able to monitor and analyse key parameters such as startup behavior, performance, pressure, temperature, vibrations, atmospheric contamination, lube oil debris and disruptions. This facility providesconstant feed back on the condition of the gas turbine.

With DECIDE we immediately detect changes in engine behaviour, which enables intervention before a failure occurs. This will prevent breakdown and repair costs, unnecessary downtime and extends the lifetime of the gas turbine.

Feedback from DECIDE allows early identification of issues to be addressed during scheduled maintenance. Optimal long-term maintenance planning is elaborated in a strategic maintenance plan.

The shift of time based maintenance to condition based maintenance results in more efficient maintenance regime and the extension of maintenance and service intervals.

Human factor

Another major factor affecting gas turbine profitability are the operators. As mentioned in our solution for Human error reduction, approximately 42% of preventable lost production in the global process industry is primarily result of human error. It is therefore reasonable to assume that the global availability and profitability of a gas turbine depends considerably on the knowledge and skills of its operators & maintenance engineers. VBR supports on-site operators, engineers & mechanics with education & training aimed at fine-tuning gas turbines for a higher efficiency preventing and solving problems. VBR also provides a help desk for real-time support.

Solutions for engine life extension in specific situations

All gas turbine based in Europe have to comply with the new NOx emission limits required by the European Industrial Emissions Directive (IED). Emission reduction retrofits can assist to prolonging engine life.

Where a hot section suffers from vitrified sand deposits obstructing the air inlet, cleaning the hot section is a cost effective way to prevent premature renewal. VBR  has achieved good results in hot section cleaning by dry ice blasting. Another option is to perform a hot section exchange on-site with minimal disruption to production.

Where a control system is obsolete or mature, a control system retrofit will bring owners and operators higher reliability, availability, performance and maintainability.

If a control system is new but does not function optimally or reliably a full (re)commissioning will improve its reliability, availability & maintainability.
