General Product Information

Recommended Interval Extension Products: Turbine

Gas turbine customers continue to look for products to increase availability while reducing maintenance costs. GT Interval extension products have been specifically developed to address both these needs. Interval extension products were developed to extend the duration between planned maintenance inspection intervals, which results in increased availability and in some cases, may eliminate certain type of inspections (e.g. combustor inspections) and reduced maintenance costs.

In the example below a unit operating at 25k EBH turbine inspection intervals now operates at 33k EBH turbine inspection intervals.

This change in operation provides the following benefits:

  1. Same number of outages and scope but extended over 133k EBH compared to 100k EBH, helping to reduce overall maintenance costs
  2. Extended duration of 33k EBH between outages which can result in improved availability
  3. Typically, interval extension products also come with advanced Siemens technologies that can help improve performance when coupled with TPU (Thermal Performance Upgrades) products

Note: EBH = Equivalent Base Load Hours, ES = Equivalent Starts, HGP = Hot Gas Inspection, MI = Major Inspection
