Repairs

Global Network of Service Centers

Since GE is continually improving turbine technology and applying it to component designs that can be retrofitted in older units, the owner can evaluate the economics associated with upgrading or uprating the unit by replacing one or more components with state-of-the-art components.

Our global network of service centers provides repair services for every component in your turbine, including auxiliary equipment. We service power generating turbines as well as mechanical drive units, from any OEM, and most in-shop services can also be performed on-site.
