The Port of Karachi is Pakistan's largest and busiest seaport, handling about 60% of the nation's cargo (25 million tons per annum). It is located between the Karachi towns of Kiamari and Saddar, close to the main business district and several industrial areas. The geographic position of the port places it in close proximity to major shipping routes such as the Strait of Hormuz. The administration of the port is carried out by the Karachi Port Trust, which was established in the nineteenth century.
The port comprises a deep natural harbour with an 11 kilometre long approach channel which provides safe navigation for vessels up to 75,000 metric tons deadweight (DWT). The main areas of port activity are two wharves; East Wharf with seventeen vessel berths and West Wharf with thirteen vessel berths. The maximum depth alongside the berths is currently 11.3 metres. The two wharves extend in opposite directions along the upper harbour – the East Wharf northeast from Kiamari Island and the West Wharf southwest from Saddar town.
