SCI's Tanker Commercial department looks after scheduling and deployment of Tankers for feeding crude to various Indian oil refineries as well as for cross-trading in international markets.

Lighterage operations on the east and west coasts of India are also undertaken, to facilitate quick turnaround of Tankers, which otherwise cannot call on ports due to draft restrictions and other infrastructural limitations.

The department also ensures commercial deployment of in-chartered tonnage, to meet its obligations of lifting cargo under the various Contracts of Affreightment (COA).

Besides handling imported crude, SCI also carries about 8-10 million tonnes of indigenous crude which needs to be moved through coastal routes. For this purpose SCI is deploying the biggest coastal fleet in the country.
