[Asia Economy Reporter Choi Seoyoon] Doosan Enerbility is partnering with Korea Southern Power to extend the lifespan of gas turbines using domestic technology.

On the 23rd, Doosan Enerbility announced that it signed a contract with Korea Southern Power for the lifespan extension work of the gas turbine rotor at the Busan Combined Cycle Power Plant.

The rotor is a cylindrical structure equipped with multiple rotating blades. It is one of the core components within the gas turbine, operating at high speeds of 3,600 revolutions per minute at temperatures exceeding 1300°C.

Extending the lifespan of gas turbine rotors requires the highest level of technical expertise and has been predominantly monopolized by overseas original equipment manufacturers (OEMs) of gas turbines. Doosan Enerbility secured this project by continuously strengthening its technological capabilities.

In particular, this rotor lifespan extension will apply Inconel alloy steel, which has ultra-high strength characteristics. Except for the original gas turbine manufacturers, Doosan Enerbility is the first in the world to do so.

Korea Southern Power, which operates the largest number of gas turbines domestically, is revitalizing the domestic gas turbine industry through various collaborations. By providing opportunities for the domestic gas turbine industry to participate in this rotor lifespan extension project, it has laid the foundation for future entry into the global gas turbine service market.

Park Hongwook, Head of Power Service BG at Doosan Enerbility, said, “We are honored to participate in Korea Southern Power’s gas turbine rotor lifespan extension project and contribute to economical power plant operation. We will successfully carry out this project and actively pursue participation in the global gas turbine lifespan extension market together with the domestic gas turbine industry.”

Doosan Enerbility is expanding its approach to the domestic and international gas turbine service markets. In 2018, it signed a long-term gas turbine service supply contract with the U.S. private power company MCV (Midland Cogen Venture) and is currently performing gas turbine rotor lifespan extension work. In 2019, it carried out maintenance work on the gas turbine exhaust cylinder at the Ulsan Combined Cycle Power Plant in cooperation with Korea East-West Power.
