Samsung Engineering Co., a construction unit of Samsung Group, said Tuesday it has received plant orders worth US$3.07 billion in the United Arab Emirates.

Abu Dhabi Oil Refining Company, an affiliate of UAE’s state-run oil firm Abu Dhabi National Oil Company (ADNOC), has placed two separate orders to Samsung Engineering in lump-sum turnkey contracts, the company said in regulatory filings.

The deal calls for the South Korean builder to be in charge of engineering, procurement and construction.
