ORAP: operational reliability analysis program-a gas turbine and combined cycle power plant reliability reporting system

The authors describe a system called ORAP (operational reliability analysis program). ORAP is a reliability, availability, and maintainability (RAM) reporting system with a specific focus on gas turbines in simple and combined cycle arrangements, various applications and duty cycles, and across the various manufacturers. This work provides a historical review of ORAP, data requirements and reporting, as well as a brief review of how ORAP supports the industry focus on high reliability
