Steam Turbine Advanced Maintenance Topics

Authored by Harold Parker with input from Bob Doughty, John Mitchell and Doug Lemmo

In any major outage, beyond routine decision making regarding disassembly/reassembly/inspection, there are those decisions that require significant thought or outside evaluation. These decisions are typically associated with steam path performance, steam path distortion, crack evaluation decisions, vibration related issues, control system issues, and making/reporting decisions based upon cost data. It is our intent to make decision making more effective on these topics.
