Daewoo E&C has been leading the construction of thermal power, cogeneration, tidal power, nuclear power plants, LNG storage, and other facilities with our outstanding technology and passion. In the overseas markets, we are competing with global players by building value-added plants. Our success has led to our being recognized as one of the “Global Top 20” through our ongoing commitment to technology development and investment in the new and renewable energy sector.

LNG, Oil & Gas

Daewoo E&C possesses unparalleled technologies in the fields of oil and gas,
as well as pipelines and storage facilities.
Daewoo E&C has constructed approximately 50% of LNG regasification plants and
storage tanks in South Korea. These include the Tongyeong, Incheon, and Pyeongtaek LNG receiving terminals.

Refinery & Petrochemical

Refinery & Petrochemical

Daewoo E&C has amassed a wealth of experience and technology
in developing petrochemical production plants and refineries.
A particularly notable milestone was building S-OIL’s Residue
Upgrading Complex (RUC) and Mixed Feed Cracker (MFC), which
allowed the company to maximize its business value.

Daewoo E&C maximizes the value of the refinery and petrochemical
industry by applying our comprehensive construction capabilities to
all facilities.

Power Plants

Building on this expertise, we have worked in Nigeria, Libya, Algeria, Morocco, and other overseas markets, gaining recognition for our technological prowess the world over.

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 1977.


In 2011, we began to develop clean ocean energy in earnest through the construction of the Sihwaho
Lake Tidal Power Plant, the largest build of its kind in the world. We will continue to expand our business
interests into the new and renewable energy sector, addressing tidal power, biogas, wind power, and
solar power, following the global trend toward eco-friendly energy.
