Oil and Natural Gas Corporation (ONGC) collaborates with Japan’s Mitsui OSK Lines. They will construct two very large ethane carriers. These carriers will import petrochemical feedstock for ONGC’s subsidiary. This move addresses changes in liquefied natural gas (LNG) composition from Qatar. ONGC aims to secure feedstock for its petrochemical plant. Ethane imports are planned to start by mid-2028.
