About The Course

The objective is to give attendees a comprehensive view of the strategy, actions and considerations involved in effectively managing and thereby assuring the integrity of piping, tubing and vessels that form the pressure boundary to steam or water process fluid. A range of topics relating to the design, inspection and repair of relevant components are treated using a combination of theory and numerous practical examples.


The examples are all based on actual project cases encountered by staff at plants around the world.

Learning Outcomes

  • Gain an overview of the most common damage mechanisms, either on the waterside or fire/gas/air-side, that can affect pressure part components in the steam cycle.
  • Learn about various methods to predict evolution of wear and damage in pressure parts (Remaining Life Assessment / Fitness-For-Service).
  • Learn about how to best plan and then perform repairs to meet the challenge of achieving schedule, cost and quality objectives.

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.
