GE Vernova’s rotor management service centers
With GE Vernova’s Center of Excellence approach for repair services, we focus our repair capabilities to achieve consistent, high-quality results.
Quality, investment and sustainability
With a global network of service centers dedicated to rotor life management services and repairs, GE is continuously investing in the latest tooling and technologies to keep our customers’ rotors running reliably for years to come. Our repair shops are also dedicated to sustainable operations through their support of GE’s Carbon Neutral Operations 2030 and Net Zero 2050 ambition and metal chip recycling programs with our suppliers, with more than 50% CO2 reduction over the rotor lifecycle when performing an RLE versus a new rotor.

GE Manufacturing and Technology Center (GEMTEC)
The world’s largest gas turbine service center, GEMTEC is located in Dammam, Saudi Arabia, and provides gas turbine components and generator rotors for frame 5, B&E, and 7F/9F.
To date, GEMTEC has serviced more than 70 customers in over 40 countries. Most recently GE invested about $3 million in GEMTEC to become qualified to perform 7FA rotor life extensions. As a result, GE was able to perform its first 7FA rotor life management solution in the Middle East.
Rotor frame sizes served: 5, B&E, 7F, 9F
Rotor capabilities: Rotor inspection, repairs, and rotor life extension services
Facility size: 12,000 square meters
Rotor life extensions performed: More than 15 RLEs completed in the last 4 years
Rotor investment: $3 million
More about GEMTEC
The GEMTEC campus includes the GEMTEC Service and Repairs Center for gas turbines, GE MENA Decarbonization Center of Excellence (COE), a Monitoring & Diagnostics Center for the remote monitoring of power generation assets, as well as GE Saudi Advanced Turbines (GESAT), a joint investment by Dussur and GE to manufacture heavy duty gas turbines and components in the Kingdom.
GEMTEC is playing a strong role in helping to achieve the goals outlined under Saudi Vision 2030 by nurturing local talent and suppliers, further diversifying Saudi Arabia’s economic base, promoting exports, and much more.
Investments in technology
GE invested about $3 million in the GEMTEC service center to become qualified to perform 7FA rotor life extensions. GE employed a seed rotor approach, where a refurbished rotor from GE’s inventory that has been inspected and updated with the latest technology to maintain safe long-term operation is sent to the customer and the rotor it replaces it sent to GE’s service center to be refurbished. This approach allows for a series of rotor life extensions and creates the flexibility of an economical solution while eliminating outage risk.
GE’s investment in GEMTEC increases the overall capacity worldwide of the 7F rotor network and enables rotor life extensions and refurbished rotor work to be done in the Middle East. The investment included purchase of specialty inspection tooling, an ultrasonic testing tank and a balancing machine. GEMTEC is equipped with the same state of the art rotor balance, stacking, and machining equipment as our other global rotor repair centers, providing us with additional capacity to meet global customer needs.
In addition, this investment is helping GE become closer to our customers by providing 7F rotor repair work in the region—providing customers with reduced lead time (at least 3 months faster than shipping the equipment to other parts of the world) and greater savings.
