Linz Strom GmbH operates three Frame 6B gas turbine units (GT1, GT2, and GT3), where GT1 and GT3 are dual-fuel and GT2 is gas-only. GT1 and GT3 are upgraded 24K models, while GT2 is a 12K model.
In addition, Linz operates two 6FA units (GT1A and GT1B): GT1A is a 6FA.01 DLN2.0, and GT1B is a 6FA.03 DLN2.6.
Like many utilities, Linz runs a fleet of similar but slightly different gas turbine models. This requires special attention to the interchangeability of hot section parts between units. To manage this complexity, Linz Strom GmbH uses TMMonitor for tracking parts, inspections, and long-term planning.
In recent years, the plant’s operation mode has shifted from continuous baseload to more cyclic and peaking operation. This change required a comprehensive five-year budget for turbine inspections, repairs, and new parts.
Using TMMonitor, Linz created multiple operational scenarios to plan future inspections depending on plant utilization. Traditionally, such an exercise in Excel could take days, as it involves detailed parts rotation planning and ensuring that shared components are used correctly across turbines. With TMMonitor, this process was completed in minutes.
The result was a complete five-year inspection and parts rotation plan, including projected service costs, repairs, and new parts requirements. Once the long-term plan was approved, Linz ran a two-year detailed simulation to finalize specific part replacements and refine budget accuracy.
The simulator generated a precise list of upcoming inspections, including capital parts and consumables required for each. Based on this plan, procurement of consumables and preparation of capital parts began well in advance. Each box in the warehouse is labeled with a part set number and QR code, linking directly to its record in TMMonitor. This ensures the correct parts are selected, for example, preventing non-upgraded S2B components from being installed in upgraded turbines.
Repairs were also scheduled in advance, allowing removed parts to be shipped immediately to the repair shop. Repaired components were then returned to site with minimal turnaround time, ensuring availability for the next inspection.
Through this process, Linz Strom GmbH achieved a more efficient, transparent, and optimized capital part stock strategy, minimizing downtime, reducing planning time, and ensuring the right parts are in the right place at the right time.
