Sustaining growth built on
advanced technology and trust.
The construction of industrial plants is a knowledge-based, high value-added sector that combines technologies in repair and maintenance, from the procurement of machinery and equipment to engineering competence, construction, supervision and trial operations.
Daewoo E&C has been leading the construction of thermal power, cogeneration, tidal power, and nuclear power plants, LNG storage, and other facilities with our outstanding technology and passion.
In addition, Daewoo E&C is making good records in high value-added plant construction competing with global companies in overseas plant markets.
Recently, we are adjusting to changes in the energy paradigm, promoting commercialization in new renewable and clean energy sectors by R&D and investment in those sectors.
LNG, Oil & Gas
Daewoo E&C has unrivaled technical skills in oil and gas transmission and storage equipment including oil and gas refining plant.
Especially in LNG liquefaction plant sector, it is leading overseas markets with high-level competitiveness and experience, including performing LNG Train 7 Project in Nigeria as the first main contractor of EPC among Korean construction companies.

LNG plants have been in the spotlight for its sustainable growth in business following a rise in LNG demand due to worldwide GHG emission reduction efforts and increased shale gas production.
Daewoo E&C has constructed approximately 50% of LNG regasification plants and storage tanks in South Korea.
These include Tongyeong, Incheon and Pyeongtaek LNG receiving terminals.
Based on such experience and technology, we have successfully performed construction of LNG processing plants, transmission equipment and pipelines in overseas markets including Nigeria, Algeria, Russia, Papua New Guinea and Indonesia.
Furthermore, we will lead in developing new markets with knowhow and technical skills accumulated through various results including LNG liquefaction plant in Nigeria and Tangguh LNG Train 3 in Indonesia.

Power Plants
Daewoo E&C has accumulated technology and experience in various power plant sectors including thermal power, tidal power, hydropower, and cogeneration since the successful completion of the Ulsan Thermal Power Plant in 1981.
Now, we are extending our interests into the new and renewable energy sector by applying our expertise to carry out large-scale EPC projects at home and abroad.

Daewoo E&C played a leading role in constructing domestic large-scale power plants including Paju Cogeneration Plant, Samcheok Green Power Plant, Pocheon Natural Gas Power Plant, starting with Ulsan Thermoelectric Power Plant.
Based on such experience, it has advanced to overseas markets in Nigeria, Libya, Algeria, Morocco, etc. and its technical skills are recognized across the world.
Recently, we are contributing to energy independence as it has accumulated various achievements in LNG combined cycle power plant such as Namjeju Combined Cycle Power Plant, Sinsejong Combined Cycle Power Plant and Bucheon Cogeneration Plant, as a part of conversion of energy for carbon neutrality.
Furthermore, we are also expanding its business sectors into new business sectors including wind power, fuel cells and hydrogen energy, in line with expansion of global market by new renewable energy.
