Particular demands are made on the operation of thick-walled boiler components: high availability, flexible stress, low maintenance costs, and operational safety. Resulting stresses are to be detected and assessed by the IT solution SR1 of STEAG Energy Services (SES) early on in order to ensure an optimal unit utilization and maintenance strategy. The benefits: Reduction of inspection effort for highly-stressed components, early detection of critical conditions and proof of the specified normal operation to authorities.
