Webinar: Last stage blade repairs on steam turbines

In-situ repairs and other solutions for reduced outage duration and costs

Date: October 19, 2022

1:00 pm CST

Presented by EthosEnergy and hosted by Combined Cycle Journal


Replacement of critical L-0 / last stage blades (LSBs) in the low-pressure section of an HP/IP steam turbine, is often very expensive and accompanied by long lead times, especially with today’s challenging supply chain issues.

What if there was a way to save up to 60% on cost and reduce outage timeframe without sacrificing the integrity of the blade or losing efficiency?

EthosEnergy’s steam turbine engineering team has developed methods to repair, rather than replace, these blades at a fraction of the cost with proven results.

These methods also have the added benefit of reduced carbon footprint by extending the life of the blades rather than manufacturing new.

Join Ian Saeger, Manager of Project Engineering for EthosEnergy, as he shares a few case studies on these solutions.
