6. Mercator
Previously known as Mercator Lines Ltd., Mercator, the next one on the list of largest shipping companies in India has irons in a number of different shipping-related fires. For example, the Mumbai-based firm is involved in oil, coal, and gas dredging, as well as commodity transportation via its subsidiaries: Mercator Oil and Gas Ltd., and Mercator Offshore Ltd. Additionally, Mercator serves as India’s second-largest private sector shipping company in terms of sheer tonnage. Founded in 1983, one of the group’s major claims to fame is its ability to conduct groundbreaking work in previously uncharted areas, such as the Tapti River, thus opening new navigational routes. With over 2,000 employees in the company, the Mercator Group represents one of India’s most significant players in the shipping and offshore industry.
