Which port is the satellite port of Kolkata port?

Haldia Port

Kolkata Port is located on the Hugli river, 128 km inland from the Bay of Bengal. Like the Mumbai port, this port was also developed by the British. Kolkata had the initial advantage of being the capital of British India. The port has lost its significance considerably on account of the diversion of exports to other ports such as Vishakhapatnam, Paradwip and its satellite port, Haldia.
