In this webinar we will cover the typical limiting factors of gas turbine components and how they can be repaired. We will cover the steps used in implementing a life time extension and will show some case studies. Some examples of how new parts are redesigned with features that make them more robust will also be covered. This webinar will be beneficial to the engineers and power plant personnel involved with the refurbishment and replacement of the gas turbine hot gas path components.

Elevated temperatures take a big toll on gas turbine components risking cracks, corrosion, wall thickness, and material condition. Repair enhancements can extend a part’s life by slowing its degradation and…
A carefully orchestrated process was set in motion when Mechanical Dynamics & Analysis (MD&A) ventured to complete a 7FA gas turbine hot gas path inspection, together with a 7FH2 generator…
Competitive maintenance uses an analytical process and condition-monitoring tools to select the optimum maintenance strategy for each plant system. For example, the optimum strategy for the plant’s steam turbine will…
Power plant control and monitoring can be complex given the need to integrate many different platforms. Adding to the complexity is the fact that HMI’s (Human-Machine Interface) supplied by the…
Mechanical Dynamics and Analysis (MD&A) was contracted after a forced outage to perform a major overhaul on a cogeneration unit’s MS5001PA gas turbine, and to remove, test and inspect the…
Mechanical Dynamics and Analysis (MD&A) was retained by a utility to perform a stub-shaft repair of a generator rotor collector-end shaft. The customer reported that the generator rotor had suffered a collector…
