India’s state-controlled Oil & Natural Gas Corporation (ONGC) has unveiled a three-year plan to execute multiple projects worth at least $7.3 billion and involving key developments offshore the west and east coasts.

ONGC recently informed leading domestic and international contractors it plans to tender 18 sizeable offshore engineering, procurement and construction projects until 2025, involving a mix of brownfield and greenfield projects, according to at least two people familiar with the development.

While 13 offshore projects worth $3.3 billion have been earmarked for the western coast region, an additional $4 billion is likely to be spent on eastern coast projects on five separate projects, one person said.
