Great Eastern Shipping is considering making a move to buy state-owned rival Shipping Corp of India (SCI).
The country's biggest private shipowner has filed an expression of interest (EOI) in the privatisation tender, the Hindu Business Line newspaper reported.
The government has extended the bid deadline for its controlling stake in SCI until 1 March, from 13 February previously.
US-based shipowner Safesea Group is expected to file an EOI "any time" before the cut-off point, president SV Anchan confirmed to the newspaper.
