MD&A is a full-service provider for the Alstom turbine. MD&A’s Gas Turbine Services project managers and technical directors are seasoned professionals with a broad range of experiences whose skill sets cover both common and unique makes and models of turbomachinery from around the world.  We have experienced Alstom turbine engineers.

Our specialized services range from Outage planning and Project management for A and B inspections, including assessment and inspection of full drive train and auxiliaries (open SBK/EV combustors for Base Fleet and closed borescope inspection for advanced fleet) to also C inspections (open, assess, repair, clean, and close unit.)

Our capabilities for the Alstom turbine also include providing Radial Rotor Position (RRP) alignment measurement and correction; along with SBK liquid nozzle rebuilds.

MD&A can perform comprehensive Generator inspection and repairs, including high voltage bushing refurbishment.

Our turbine-generator repair facility located in St. Louis, MO can accommodate generator field rewinds of any capacity, including large 4-pole nuclear units.  Our generator experts can also perform a stator rewind on-site. Through years of power generation industry experience, our generator repair specialists conduct full scope electrical testing, visual inspections, and specialty tests as per customer requirements.

We invest heavily in the development of people, procedures, and principle which facilitate improvements in design, reliability, and performance.  Our generator experts designed many solutions to numerous aging fleet issues; for example, Alstom Generator Pole to Pole Connector Modification.   

Within our Turbine-Generator Repair facility, our high speed balance facility is one of the most modern balance facilities for power turbines in the world. Proper balancing of the turbine and generator rotors is extremely vital to ensure proper operation. The facility allows for effective testing to ensure minimal vibrations in any manufacturer’s rotor throughout testing. This same facility also offers field machining services.

MD&A maintains several portable machine shops for use during customer’s plant projects. Shops are contained in portable Conex trailers for easy lifting once we deliver them to your door. Our portable machine shops come stocked with metal grinders, a drill press, lathe, and other handy tools needed to address metals work projects.
