SCI is the largest Tanker owner in India, with a well-diversified fleet of crude oil tankers consisting of all sizes: MR, LR-I, LR-II, Aframax, Suezmax and VLCC Tankers. SCI's Tanker tonnage paralleled the growth of Indian oil industry since the mid-1970s. Till late 1990s the tonnage predominantly catered to Indian crude oil and product transportation. This was done keeping in view the specific constraints of terminals/ports in India and infrastructural limitations like draft, availability of tankages, length/capacity of jetties, etc.
