Field Scanning (Industrial Gas Turbine)

L3I excels at providing industrial gas turbine (IGT) users the engineering and testing services that will help maximize a unit’s availability and performance and reduce life cycle costs. We can gather information up to 800 points/mm2.

To date, we have performed countless outage inspections and component engineering. Our field services are backed by our more than 1000 man-years of experience in design, analysis, hardware fabrication, field inspection, and failure investigation on IGT compressors, combustors, turbines, exhausts, rotors, bearing compartments, casings, and engine secondary air systems.

We offer the following services for power generation customers:

• Development of Root Cause Analysis for Compressor, Turbine, Combustor and Other Components
• Consulting Services During Catastrophic Failures Maintenance Outage Inspections for Quality Control
• Third party inspection and documentation of major gas turbine components
• Experience in supporting minor inspections and major inspections
• Inspection and documentation of condition of new hardware coming into engine
• Evaluation of design feature changes and their potential effects to unit operation
• Technical Analyses to Determine Component Operational Stresses and Deflections
• Technical Analyses to Determine Component Remaining Life
• Development of Condition-Based Maintenance Programs
• Technical Analysis and Laboratory Testing to Validate Component Repair Processes

The Level 3 approach replaces traditional plate inspection or a CMM system with WLS, which can capture and calculate precise 3D coordinates for millions of points in seconds. CMM captures only a few points in the time that WLS can capture hundreds of thousands, so Level 3 is able to do a more thorough inspection. The results are much more visual and therefore much more easily understood and interpreted.
Nuclear containment and power generation inspection poses some unique challenges, such as analyzing the dimensions of a newly manufactured part compared to the CAD model. This is difficult using a CMM system, which
depends on the operator to accurately capture the points that will show whether or not the part is conforming
within the allowable tolerance. Often, there is not enough point data to make an accurate comparison.
