Extending inspection intervals for ExxonMobil's critical gas turbines via digital condition-based maintenance
Overview
Challenges
- Aeroderivative gas turbines in LNG liquefaction process require Level 1 inspections roughly every six months or 4,000 fired hours
- The traditional approach includes a boroscopic inspection and therefore requires a week or more shutdown
Results
- Baker Hughes' Dynamic L1 is a remote diagnostics solution that extends the Level 1 maintenance interval from roughly 6 to 24 months
- It avoids all the typical maintenance costs and lost production associated with traditional fixed-interval shutdowns, and continuously monitors the tubines to deliver prioritized reports of any maintenance that's actually required

Case study details
One of ExxonMobil's LNG facilities uses 13 of our PGT25+G4 gas turbines for liquefaction mechanical drive. These two-shaft machines are well known industry-wide for their high efficiency, reliability, availability, and low environmental impact. But they still need to be inspected every six months. That is, until now.
Our Dynamic L1 solution applies a condition-based, predictive maintenance strategy to extend the Level 1 turbine inspection interval from the typical 4,000 fired hours up to 17,500-or from roughly every six months up to two years.
