MD&A is a worldwide leader in the repair and refurbishment of gas turbine fuel nozzles. Our advanced engineering expertise combined with leading-edge equipment delivers reliable, extended life of new or refurbished fuel nozzle products. With lean manufacturing principles, and a commitment to quality improvement, we maximize customer value.

Our turnkey outage management includes Combustion, Hot Gas Path, and Major Inspections. Today, we continue to expand our talent and employ many of the best minds and technical experts in the industry. Our turnkey labor specialists provide testing, inspection, maintenance, training, and repair of the GE 7EA turbine in more than 20 countries worldwide.

Our experts also offer compressor vane pinning to address shim migration and vane rocking issues experienced on some large frame gas turbines.

The Design Service Life, aka End of Life (EOL), of a gas turbine rotor, can be based on statistical predictions of component life, based on an assumed operational mission mix; each rotor component is influenced differently by operational stresses, temperatures, and duty cycles. We look at the Gas Turbine Rotor & Compressor Rotor. An End of Life Evaluation can help decide if component Repair, Replace or Use is the best option for your gas turbine rotor to meet operational and maintenance forecasts.

Frame 7EA Rotor Repair Capabilities:

  • Contains all Fixtures and Tooling
  • Completed Unstack & Restack of Compressor & Turbine Sections on Multiple units
  • Completed Scans of all Compressor Disks
  • All components reverse engineered & Intellectual Property developed
  • New turbine and compressor components stored in Gas Turbine Rotor shop for easy access, including wheels and discs

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. Our machining capabilities include the ability to on-site or in-shop repair horizontal joints on turbine casings, rotors, and nearly any rotating or stationary GE 7EA turbine component.

Additionally, MD&A maintains several portable machine shops for use during customer 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, a lathe, and other handy tools needed to address metals work projects.

MD&A Bearings, Seals, and Hydraulics Division has helped many customers eliminate the undesirable effects of oil whip or steam whirl by designing, manufacturing, and repairing elliptical bearings and tilt pad journals for the GE 7EA turbine. A bearing retrofit can be a cost-effective solution when changes in operational practices or steam path modifications have created an undesirable oil whip or steam whirl condition. 

Troubleshooting the source of differential thrust bearing temperatures can be frustrating and costly, especially if load reduction action is required. MD&A has earned the trust of many customers to design, manufacture and repair tapered land thrust and tilt pad thrust bearings. We offer profiling of fixtures, material upgrades, and performance monitoring instrumentation. 

MD&A Bearings, Seals, and Hydraulics Division also offers Rapid-Spares bearing exchange by assuring customers that their bearings are ready to ship, in many instances, even before an outage begins, while also offering bearing refurbishment and complete oil deflector reconditioning.
