AVOID AN UNPLANNED PLANT OUTAGE
We know how to repair your Chinese OEM steam turbines and generators
Over the last 8 years we have executed more than 20 major and minor inspections and 30 steam turbine retrofits on 16 GW of installed units for customers globally who have fleets similar to yours. In addition to fixing some recurring issues and preventing unplanned outages, we have also helped to create approximately $300 million USD in additional value to our customers through an increase in power, reduction in fuel consumption and extended outage intervals.
GE CAN PROVIDE COST SAVINGS AND IMPROVED AVAILABILITY
Let’s work together to keep you producing power
Why wait for a forced outage when you can have GE investigate the condition of your Chinese OEM units and develop a quick solution to keep you online? Explore our areas of steam turbine fleet expertise and learn how we can partner with you to improve the performance and reliability of your existing units.
We have observed 28 units with steam turbine blade failure issues to date for 300 MW and 600 MW class units globally.
Our solution includes quick onsite support and the re-engineering of blades with improved material and/or design to provide enhanced performance and quality.
We have repaired multiple bent steam turbines from Chinese OEM to date.
Our rotor repair services can be completed within 4-10 weeks, potentially saving our customers $10-12 MM by reducing turbine downtime.
Our solution includes onsite balancing of the rotor, and if needed the rotor will be shipped to one of our repair shops for heat straightening and machining.
Valve spindle sticking or breakage, steam leakages, and valve seat cracks can cause your turbine to overspeed and impact the safety of your fleet. We have observed more than 10 cases and repaired 3 units recently, and we can address all your valve internals within 2 to 3 weeks, potentially saving up to $3 MM by reducing turbine downtime.
Our solution includes onsite 3D scans for measurements and a re-engineered solution using better materials to improve performance.
Steam turbine rotor steeple cracks can lead to catastrophic equipment failure. We have successfully completed rotor steeple repairs on 5 units and put them back online in 8-10 weeks—compared to the average delivery time of 10-12 months for a new rotor—potentially saving our customers up to $10 MM by reducing turbine downtime.
Our solution includes repair or replacement of rotor with an improved design to enhance performance. Solution depends on specific steeple design.
Clearance issues in flow path and shaft end sealings can result in poor performance, shaft end leakage, high steam extraction and serious turbine damage. We have successfully executed more than 20 major outages, including adjustments on all turbine sealing clearances and replacement of sealings when needed.
Our solution includes readjustment or replacement of sealings within a standard outage schedule, resulting in a heat rate improvement of up to 1%.
Does your installed fleet have known generator issues, including stator bar blockages, leakages and overhang vibrations?
We have successfully completed clearance repairs on Chinese OEM generators, potentially saving our customers up to $8 MM by reducing generator downtime.
Our solution includes stator bar flushing, leakage repairs and overhang vibration.
