Doosan’s Chilean steam turbine designed to withstand seismic forces

Doosan Skoda Power has been awarded a turnkey contract to supply a high-efficient steam turbine generator set for IEM1 coal fired power plant in Chile.

The plant is located in an area with a lot of seismic activity, something Doosan Skoda have allowed for in their turbine design.

IEM1 (Infraestructura Energética Mejillones) will be the largest Doosan Skoda steam turbine installed in Latin America with 375 MW power output, located in Antofagasta region.

An EPC contract for the entire project was awarded to South Korean SK E&C. The investor will be E.CL, a Chilean company engaged in the production of electrical energy and principally oriented towards mining companies and other industries in the north of Chile. The company is a subsidiary of French ENGIE (ex-GDF Suez).

The Skoda steam turbine is specifically designed to withstand high seismic activity in Chile and is based on a proven Skoda design that is safely operated within one of the world highest earthquakes zone, on similar installations near the Antofagasta Region.

The turbine has a double casing design with a combined high pressure and intermediate pressure part, a double flow low pressure part, and steam reheat, and use advanced and well-established structural elements and nodes such as highly efficient 3D blading and welded rotor.

The EIM1 Power Plant is scheduled to come online in mid-2018 and design manufacturing of major components is within the schedule with delivery by the end of 2016.
