Let’s say a blade failure in your Chinese OEM steam turbine results in a forced outage. What happens next?
The GE team has extensive experience across OEM and other OEM fleets for critical blade repairs and supply through re-engineering. The first thing we would do is get our on-site support team to the site quickly. From there, we would work with customers to identify the root cause of the issue, using 3D scans to take measurements. Depending on the results of the investigation, we can either repair and or re-engineer the blades.
When re-engineering a blade, we start by developing tailored manufacturing documentation and then introduce material or design improvements. It then goes through GE’s quality assurance program before being delivered to the customer.
Recently we worked with a customer in Saudi Arabia that operates a fleet of Chinese OEM steam turbines. We went to their site immediately after they contacted us about a blade failure and performed a measurement on the broken blades. Based on our fleet knowledge, we suggested that the customer also inspect another LP rotor for any last stage blade issues. As expected, there were cracks in the blades. After measuring the blades and performing a root cause analysis, we were able to re-engineer the blades according to our design expertise and offer the customer new and improved blades.
Be proactive and check your fleet!
This is what I advise all plant owners of Chinese OEM steam turbines and generators. Don’t wait for a failure to occur! If you have a Chinese OEM turbine, you might already be experiencing one or more of these issues. If not, you probably will soon.
