Solving the Discontinued Hardware Crisis

The GE Mark VI control system was deployed across hundreds of gas turbine installations worldwide from the mid-1990s through the 2000s. Many of these plants are still in active commercial operation, with remaining asset life measured in decades — not years. GE's transition to the Mark VIe and subsequently to newer platforms has left a structural gap: the hardware is still running, but the supply chain has dried up.

The strategy is not complicated. Identify the boards with the highest failure exposure — those in high-cycle duty, those in humid or high-vibration environments, and those with no redundancy. Procure verified spares from a traceable source. Store them correctly. That discipline, applied consistently, is what separates plants that control their maintenance budget from those that are controlled by it.

Key Features for System Maintenance

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Q: Can you confirm compatibility with my specific Mark VI configuration before I order?
A: Yes. Provide your system's software version and existing board revision, and our technical team will confirm compatibility before the order is placed.
