Daewoo Engineering & Construction Co., Korea's third-largest builder, said Thursday it has secured a US$250 million gas pipeline contract in Nigeria.

The turnkey contract calls for Daewoo E&C to build a 69-kilometer-long gas pipeline and related facilities in swamp sites, about 65 kilometers southeast of oil-rich Warri in the Delta state, by February 2015.

The company said it signed the deal with Shell Petroleum Development Company of Nigeria, a joint venture between Royal Dutch Shell Plc and the Nigerian National Petroleum Corporation, on Wednesday.

Daewoo E&C has carried out 60 projects worth about $6 billion in Nigeria since 1978, when it made its foray into the West African nation. (Yonhap)
