Two pilots are said to be missing after the crash. The Indian Coast Guard and ONGC have diverted their offshore vessels to locate the missing helicopter, according to reports.
The Medivac chopper was on its last sortie of the day from an offshore platform in the Mumbai High South oil and gas field, about 160 kilometres, off the India’s western coast, the Press Trust of India reported.
There were no passengers aboard, according to the Press Trust.
ONGC’s director of offshore, TK Sengutpa, said no cause of the crash has been determined.
“We don’t know the reason for that,” Sengupta told the Press Trust. “The pilots on the board are still missing. We don’t know their whereabouts.”
There was no reported damage to the oil infrastructure.
