Life Management

Life ManagementEffective life management of gas turbines reduces the costs associated with component upgrades or replacements. We understand the significance and complexity of gas turbine operation and possess the advanced technical skills necessary to increase turbine lifecycle.

Based upon many years’ experience with the performance of gas turbine materials and coating systems, we provide specific advice on material condition related to degradation from chemical, mechanical and hot corrosion exposure.

We focus on determining the rate at which components degrade within a particular operation. These rates are relatively unique to each individual turbine based upon its distinct operational profile.

Condition assessment is essential to materials life assessment and optimizes performance while assisting with replacement and refurbishment decisions. Through an understanding of component performance, it is possible to:

�� Determine remaining life of turbine discs and rotors and provide safe life extension strategies

�� Determine replacement intervals for specific components

�� Assess suitability for repair or rejuvenation of strategic components

�� Calculate risk associated with extended operation or deviation from normal practice

Turbine Root Cause Failure AnalysisDetermining the failure modes in gas turbines is crucial to minimizing the impact on plant operations. We provide a comprehensive root cause failure analysis service for a wide range of applications, operating regimes and environments.

We have extensive expertise and many years experience providing root cause failure analysis services for gas turbines – both to turbine operators and insurers – often as an expert witness or in support of insurance loss adjusting.

Our People We specialize in life management, life assessment and life extension. We conduct extensive in-house research into inspection techniques, high temperature materials, life assessment methods and life prediction and we have been active in materials research since 1926.

Our senior and principal engineers all have over 20 years experience with critical power generation assets.
