ExxonMobil is strategizing according to the new global shipping fuel regulations to be effective from 2020. The energy major will plan on a multi-billion dollar investment in its Singapore refinery. It is Exxon’s chief petrochemical complex with a 592,000 bpd capacity. This move is in line with the IMO’s new rules to limit the sulphur content to 0.5% from present 3.5% in order to reduce pollution by ships worldwide.
