The GE GRSS Center has now expanded its repairs scope to include HA rotor repair capability, a crucial service that ensures the long-term reliability and availability of H-class gas turbines.
GE’s Gas Power business celebrated a significant milestone as it completed the repair and return delivery for the 100th set of Hot Gas Path components from its GE Repair Solutions Singapore (GRSS) Center. This accomplishment underscores GE’s commitment to enhancing its supply chain capabilities and better serving its customers in the power generation sector. The GRSS Center, which received a $60 million investment in 2019, aims to become a global leader in power generation technology development, implementation, and repairs.
The GRSS Center has now expanded its repairs scope to include HA rotor repair capability, a crucial service that ensures the long-term reliability and availability of H-class gas turbines throughout their life cycle. With support from the Singapore Economic Development Board, GE’s commitment focuses on strengthening repair capabilities globally, with a particular emphasis on Asia, where the H-Class installed base is rapidly growing.
Amol Mody, President of Services, Asia Pacific and South Asia, GE Gas Power said, “This project marks our unwavering focus to improve our supply chain capabilities and better serve our customers, which is crucial as GE’s largest and most advanced gas turbine will continue to mature and age in the coming decades. Our HA advanced fleet is one of the most responsive and flexible in the industry and can be a great complement to variable renewables sources. In recent years, we celebrated significant growth of our HA gas turbine orders in Asia, mainly to support growing power demand while switching from coal-fired power generation. GRSS’ HA rotors repair services will enable power producers to service operating assets with the latest technology, while benefiting from significant improvement to the lead time and support in their outage needs. By investing in our GRSS facility, our customers in Asia and around the world can benefit from high quality rotor services, with faster turnaround times, keeping their assets in reliable operation for years to come.”
The gas turbine rotor is a critical component of the HA gas turbine and requires scheduled servicing over its lifetime to maintain optimum condition. The enhancement of GRSS’s repairs scope is part of GE’s global Rotor Life Extension program, which aims to extend the rotor’s lifespan and enhance its efficiency by leveraging GE’s expertise to determine the full residual part life. This capability will increase flexibility across GE’s global repair network, catering to the growing installed base of HA gas turbines in Asia and worldwide. The new capability will reduce rotor maintenance costs and cycle time, enabling faster delivery to customers in Asia due to simplified logistics and regional proximity.
The GRSS Center has evolved from its origins in marine and offshore repairs in the 1970s to include power generation repairs and servicing of gas turbines. Over the years, the center has experienced significant growth, expanding its workforce from 250 to approximately 350 employees in just four years. With the goal of handling more complex repairs on HA turbines, the center aims to add further job positions. As a global center of excellence for HA repairs, GRSS is the first HA repair development center outside of the USA and one of the world’s only four heavy-duty rotor service centers.
“We welcome GRSS’ decision to introduce new rotor repair capabilities in Singapore for GE’s largest and most advanced gas turbine to better serve their customers in Asia. GE’s expansion is testimony to Singapore’s strengths as a location for advanced manufacturing and repair activities. We look forward to deepening our strong collaboration with GE and GRSS”, said Lim Tse Yong, Senior Vice President and Head, Mobility, Industrials and Conglomerates, Singapore Economic Development Board.
GE’s decision to introduce new rotor repair capabilities in Singapore highlights the country’s strengths as a hub for advanced manufacturing and repair activities. Mr. Lim Tse Yong, Senior Vice President and Head of Mobility, Industrials, and Conglomerates at the Singapore Economic Development Board, expressed their excitement about the collaboration with GE and GRSS, emphasizing the deepening of their strong partnership.
In addition to its HA repair capabilities, GRSS also serves as a global center of excellence for F-class bucket repairs and GE’s largest F-class turbine blade repair service center. Furthermore, it is the largest GE Gas Power aeroderivative repair service center with combustor DVM coating. To strengthen repair capabilities in the region, the Advanced Manufacturing & Repair Technology (AMRT) Centre was established within GRSS in 2021, with a particular focus on the HA fleet.
GE’s repair network, including GRSS and other repair shops in Asia, such as Phu My in Vietnam and PT GE Nusantara Turbine Services Shop in Indonesia, demonstrates the company’s commitment to regional innovation, local talent development, and building local supply chains. These repair capabilities for heavy-duty and aeroderivative gas turbines in the region provide 24×7 support and quicker turnaround times for customers.
