Case Studies
Explore our case studies to see how we solve complex engineering challenges for our clients.
- Case Study
A 17MW Geothermal steam turbine had a persistent casing half joint leak recurring across three outage cycles. ProGen's root cause analysis identified exhaust casing distortion as the cause, and a targeted repair procedure returned the turbine to service leak-free.
- Case Study
The 320 MW HTC unit was shut down following restricted valve movement, revealing the chest seat had come adrift and caused significant damage. ProGen identified the root cause and delivered a fully customised seat redesign, restoring valve function and addressing weaknesses in the original OEM design.
- Case Study
A 250MW CA Parsons turbine IP cylinder was opened for inspection to find severe shroud separation across rotating and stationary blade shrouds. With re-blading ruled out due to cost and spares availability, ProGen proposed and engineered an innovative weld repair — a first of its kind carried out in New Zealand.
