The Directorate General of Shipping (DG, Shipping) has asked India’s biggest oil explorer Oil and Natural Gas Corporation (ONGC) to recall 27 of its 46 supply ships for undergoing safety audits immediately. The DG Shipping directive, which could lead to the disruption in oil production, has come within days after an ONGC-chartered ship, Samudrika-10, sunk off the Mumbai coast, killing five people on board. In a notice dated July 11 to ONGC, the DG Shipping ordered around 27 OSVs (offshore supply vessels) to be recalled to the base for undergoing safety management tests before resuming duty at Bombay High. ONGC operates 46 offshore supply vessels which help in production and maintenance of India’s largest oil field, Bombay High, situated 160 kilometers north west of Mumbai.
