Station:

• Coal-fired, 4 x 650MW, located in the far east

Objective:

• Comprehensive life assessment of HP-IP-LP turbines, prior to possible corporate re-structuring
• Evaluation of start-up/shut-down procedures

Approach:

• Detailed finite element analysis of all thermal and mechanical loads during steady running and current hot, warm and cold starts
• Creep and fatigue life assessment in conformity with R5 methodology

Benefits:

• Established that remaining life exceeds operational requirements
• Confirmed that current start-up/shut-down procedures are relatively innocuous and do not need to be changed to extend life
• Components ranked by life consumption
• Future inspection prioritised by critical location
