side changing the topography of the port. To handle vessels with as much as draft, the port developed the outer harbour, named Bharathi Dock, for handling petroleum in 1972 and for mechanised handling of iron ore in 1974. In 1972, the first oil jetty was constructed at Bharathi Dock-I capable of handling tankers up to 100,000 DWT to handle imports of crude oil destined for the Manali Oil Refinery (later named the Chennai Petroleum Corporation Limited). In 1974, the iron ore berth was added to the port for exports to Japan and other countries in the Far East. The second oil jetty was added at Bharathi Dock-III in 1986 capable of handling tankers up to 140,000 DWT to meet increasing demands for crude oil and petroleum products. The iron ore terminal is equipped with mechanised ore-handling plant commissioned in 1977 at Bharathi Dock-II capable of handling ore carriers of maximum size 1,45,000 DWT, one of the three such facility in the country, with a capacity of handling 8 million tonnes and a loading rate of 6,000 tonnes per hour. The port's share of iron ore export from India is 12 percent. The dedicated facility for oil led to the development of oil refinery in the hinterland. This oil terminal is capable of handling Suezmax vessels. In the 1970s, containerisation started in India in a limited way with the creation of interim container handling facilities at Mumbai and Cochin ports in 1973. During the same period, Chennai Port began handling containerised cargoes. In 1983, a container terminal was built at the Bharathi Dock with a quay, a container yard, and a container freight station, which was commissioned by the then prime minister Indira Gandhi on 18 December 1983 as the country's first dedicated container terminal facility. The terminal was provided with tow-shore cranes and other shore facilities. In 1991, the port's container terminal quay was lengthened by with two additional tow shore cranes. In November 2001, the container terminal and back-up area was privatised through a 30-year concession with Chennai Container Terminal Private Limited. Continually increasing container traffic resulted in another extension of the quay in 2002, bringing the total berth length to . During 2008–09, the port recorded a 17.2-percent share of container traffic in India. Having the capability of handling fourth-generation vessels, the terminal is ranked among the top 100 container ports in the world. To meet the demand
