About The Course

Efficient and thorough inspections are a key factor in assuring long-term asset integrity.  This course will give attendees comprehensive insight into how to efficiently plan, execute and document inspections of Heat Recovery Steam Generators and directly associated steam-cycle balance of plant equipment such as steam drums and power piping.


Each attendee of this training course will receive a copy of the book HRSG Inspection Planning Guide, 2nd Edition, ISBN 0-9719616-2-X (163 pages).

Learning Outcomes

  • Understand the basic process and design features of various HRSG designs and how they influence risk of damage and consequently the scope of inspections
  • How to plan “judicious” inspections within time and budget constraints and thereby assure the best quality data for your O&M
  • Review the available inspection techniques and technologies, their benefits and limitations
  • Know the essential elements of writing clear and concise inspection reports

Who Should Attend

Although this training course is primarily aimed at O&M staff working in the plants, the content is also very relevant to corporate engineering and plant management staff that are concerned with assuring asset reliability and integrity.

Expert Course Faculty

Our key expert trained as a Nuclear Engineer, with a BS in Physics (1978), and MS in Nuclear Engineering (1980) from Rensselaer Polytechnic Institute (RPI) in Troy New York. After graduation, he started working in the Reactor Physics group of Combustion Engineering in 1980, designing reactor fuel enrichments for power generation reactors.


He later worked for Raytheon Co. on improving the survivability of electronics in nuclear environments. This was followed by several years at a small start-up developing control systems for diesel power plants. Since 1991, our key expert has been at his current company, where he is now a Managing Director and Principal Engineer of an European subsidiary.


His experience covers the entire steam cycle of combined cycle and conventional thermal power plants. This includes performing several hundred field missions to plant sites on 5 continents for boiler/HRSG inspections, and failure root cause analysis.


Our key expert’s current work is not focused on the practical and cost-effective application of thermo-hydraulic, mechanical and fluid flow simulations to predicting boiler and piping component degradation issues encountered in the field.
