History of Ports in West Bengal
West Bengal has a rich history of ports that date back to the ancient times. The first port in West Bengal was established by the ancient Greeks in the 4th century BC, at the site of modern-day Chandraketugarh.

The port city of Chandraketugarh was a major trading center during the ancient times, with trade links with the ancient Greeks, Romans, and Chinese. The city was an important center of commerce and culture.
The port of Kolkata was established by the British East India Company in 1690, and it quickly became a major hub for trade and commerce in the region.
Company Rule: 1773–1857
During the early colonial period, the main purpose of the port administration under the company's naval office was to provide pilotage services to ocean-going vessels.
The Master Attendant regularly conducted river surveys to report on the navigability of the river, which was a crucial task given the port's lack of docking facilities.
In 1790, the first dock was built near Bankshall Ghat, marking a significant milestone in the development of the port.
Colonel Watson was granted a site on the southern boundary of the harbor to build a floating dock in 1781, but he was forced to abandon the project due to legal disputes.
Several plans were made to build floating docks in Kolkata and Diamond Harbour in the 1820s, but none of them materialized.
The disastrous cyclone of 1842 caused extensive damage to ships anchored in Kolkata harbour, bringing the issue of dock construction back into discussion.
The government actively worked to establish the Port Trust to bring more efficiency to the management of the Port of Kolkata, providing a solid base for the British Empire's trade in India.
British India: 1857–1947
During the British India period, Kolkata's port underwent significant development. The city's merchants demanded a port trust in 1863, but it was only after a devastating cyclone in 1864 that the colonial government took action.
The cyclone caused extensive damage to the port and the city, with estimated losses exceeding 99,000 rupees. The Hooghly River witnessed high tides of about 40 feet.
In response to the disaster, the British government formed a River Trust in 1866, but it soon failed. The Calcutta Port Act was passed in 1870, creating the offices of Calcutta Port Commissioners.

At that time, the Calcutta port had only four jetties and one wharf for unloading cargo, with a total capacity of 48,000 tons. By 1871-72, the number of jetties had increased to six, with a capacity to berth 143 ships and handle 222,000 tons of cargo.
The port's growth was driven by the increasing demand for jute products and other commodities. Tea exports from Assam and North Bengal also played a significant role in the port's development.
A wet dock was set up at Kidderpore in 1892, and a petroleum wharf was built at Budge Budge in 1896. The Khidirpur Dock II was completed in 1902.
The port continued to grow, with the import-export sector experiencing remarkable development before World War I. Coastal trade also developed significantly, particularly in the export of coal.
India: 1947–Present
After India gained independence in 1947, the Port of Kolkata's facilities were revived through economic changes. The First Five Year Plan called for the acquisition of new vessels for the port.
The Haldia Dock project was initiated in the Third Five Year Plan to ease the pressure on the Port of Kolkata. This was done to manage the increasing traffic and cargo.
The Commissioners for the Port of Kolkata were responsible for the port until 1975. The Major Port Trusts Act of 1963 came into force in January 1975, leading to a change in management.
The Farakka Barrage was designed to divert water from the Ganges into the Hooghly River to remove silt from Kolkata harbor. This was done to reduce the need for regular mechanical dredging.
The Farakka Barrage is 2,304 meters long and began operations on 21 April 1975. However, it was found that the water flow diverted from the barrage was not sufficient to satisfactorily desilt the river.
The port was renamed to Syama Prasad Mookerjee Port on 12 January 2020 by Prime Minister Narendra Modi. This was done to commemorate 150 years of operation of Kolkata Port at the Netaji Indoor Stadium.
Port Infrastructure
Haldia Port has modern facilities for handling various categories of cargo, mainly of bulk type, including coal, iron ore, and petroleum products. This makes it easier to transport these goods.
One of the advantages of Haldia Port is its deep-water amenities, which allow larger-sized vessels to be stationed there. This is a significant improvement over Kolkata Port, where draft limitations make it difficult for larger vessels to dock.
The deep-water amenities at Haldia Port enable it to handle larger vessels, which is a major plus for trade and commerce in the region.
