The refinery was conceptualized in the 1960s because Bandar Abbas's location, which is strategically situated near the
Persian Gulf, was chosen for its deep-water access and proximity to crude oil reserves. A partnership between
Snamprogetti and
Chiyoda Corporation led to the construction of the refinery, with the Italian company responsible for engineering, procurement, and project supervision. Currently, its stated capacity exceeds 320,000 barrels per day (BPD). == Accidents ==
