Port of Kolkata

The Port of Kolkata, officially Syama Prasad Mookerjee Port, is the only riverine major port in India, in the city of Kolkata, West Bengal, around 203 kilometres (126 mi) from the sea. It is the oldest operating port in India and was constructed by the British East India Company. Kolkata is a freshwater port with no variation in salinity. The port has two distinct dock systems – Kolkata Dock System and Haldia Dock Complex. As an important riverine port, it provides both domestic and international freight and passenger services, being the terminus of India's longest National Waterway.

History
Early time In the early 16th century, Since the arrival of the Portuguese, who established the first European contact with Bengal, customs duties collected from trading settlements upstream of the Hooghly River heralded a change in the navigational system of the Ganges. The prosperous Saptagram port at the confluence of the Saraswati and Bhagirathi River was becoming increasingly impassable for ocean-going cargo ships. At this time, the Portuguese first used the present location of the port to anchor their ships, since they found the upper reaches of the Hooghly river, beyond Kolkata, unsafe for navigation. By the end of the 16th century, large Portuguese ships were anchored in Betor. Betor was a place on the outskirts of Kolkata. From Saptagram (Santgao) the goods were ferried by small ships and loaded onto larger ships. In 1570 AD, the Portuguese shifted their trading post from Saptagram to Hooghly, a few miles downstream. Soon Saptagram was replaced by Hooghly as the sea outlet of the region. Hooghly maintained its importance throughout the 17th century. A few decades later, after the Portuguese were driven out by the Mughals in 1632 AD, the Dutch and the English established their trading posts here. But, the trade of Hooghly further downstream, especially as far as Sutanuti and Gobindpur, encouraged the expansion of smaller trading centers and settlements into larger scale activities. Kolkata was a small river port inhabited by weavers and artisans before it was developed as a center for maritime trade by the British East India Company. The port on the Hooghly shore acted as a catalyst in the transformation of the city of Kolkata from a small weaving settlement to a major center of maritime trade in East India. Job Charnock, an employee and administrator of the British East India Company, is believed to have founded a trading post at the site in 1690. Even before settling in Kolkata, the British knew that among the navigable areas of the Hooghly River, the deepest water area is along the eastern bank from Gobindpur to Garden Reach and was easily navigable by large sea-going vessels. Since the area was situated on the river with jungle on three sides, it was considered safe from enemy invasion. From the mid-eighteenth century the growth of Kolkata's port was accelerated by the decline of the Mughal-era major ports of Hooghly on Hooghly River and Surat on the western coast. Company Rule: 1773–1857 In the early colonial period, the main purpose of the port administration under the company's naval office, headed by a master attendant, was to provide pilotage services to ocean-going vessels. The Master Attendant also regularly conducted river surveys to report on the navigability of the river. The port's lack of docking facilities became a particular concern from the mid-eighteenth century, as ships were taken to Bombay for repairs. In 1790, the first dock was built near Bankshall Ghat. Already in 1781, Colonel Watson was granted a site on the southern boundary of the harbor to build a floating dock. Watson set up a marine yard at Kiddirpor and also began construction of a floating dock in 1781, but was forced to abandon the project when legal disputes arose. Watson subsequently turned to shipyards and built a small number of ships before his retirement from the business. After Watson several steps were taken to establish shipbuilding factories in Kolkata, but none of them were comparable to the shipbuilding activities of Parsi Enterprises in Bombay. twice by the Japanese forces. On 12 January 2020, the port was renamed to Syama Prasad Mookerjee Port by Prime Minister Narendra Modi on the occasion of 150 years of operation of Kolkata Port at Netaji Indoor Stadium. The port is part of the 21st Century Maritime Silk Road that runs from the Chinese coast via the Suez Canal to the Mediterranean, there to the Upper Adriatic region of Trieste with its rail connections to Central and Eastern Europe. ==Dock systems==
Dock systems
The Kolkata Port Trust (KoPT) manages two separate dock agglomerations, the Kolkata Dock System (KDS) and the Haldia Dock Complex (HDC). These two dock systems are located on the banks of the Hooghly River, giving the port the distinction of being India's only riverine major port. Kolkata Dock System {{multiple image |perrow=2/2|total_width=380|caption_align=left|image_style=border:none;|background color=#F7E7CE It is situated on the left bank of the Hooghly River at about upstream from the sea. The pilotage station is at Gasper/ Saugor roads, 145 Kilometres to the south of the KDS (around 58 km from the sea). The system consists of Khidirpur Dock (KPD), Netaji Subhash Dock (NSD), Budge Budge River Mooring (BB), Diamond Harbor Anchorage, Sagar Anchorage and Sandheads Anchorage. This dock system mainly serves container ships and barges. Among the docks and moorings in the Kolkata dock system, Khidirpur dock has the lowest water depth, while the Budge Budge river mooring has the highest water depth. Apart from this, there are around 80 major riverine jetties, and many minor jetties, and a large number of ship breaking berths. Vessels to enter Khidirpur Dock (KPD) and Netaji Subhash Dock (NSD) of the Kolkata Dock System first wait for tides at the anchorage at Nazirganj Flats, north of Garden Reach. 5 ships can be anchored together in this anchorage. When the water level of the river reaches the level of the Kolkata Dock System (KDS) water level due to tidal action, the ships waiting at the anchorage enter Khidirpur Dock (KPD) and Netaji Subhash Dock (NSD) through lock-gates. Kidderpore Dock (KPD) Kidderpore Dock has a total of 18 berths, including 17 multipurpose berths and 1 berth for passenger ships including cargo; 6 Buoys / Moorings and 3 Dry Docks. Berths are identified by numbers, which can range from 1 to 29. The berths have uneven water depth, with a minimum of 7.4 metres (24 ft) at berth No. 29 and a maximum of 9.2 metres (30 ft) at berth No. 8. Kidderpore Dock is divided into two parts, which are KDP-1 (West) and KDP-2 (East). Out of total 18 berths, KDP-1 consists of 10 berths and KDP-2 consists of 8 berths. These two parts – KDP-1 and KDP-2 – are separated by a bascule bridge. The dock's quays have a combined length of 2,956 meters (9,698 ft), of which KDP-1 (West) is 1,728 meters (5,669 ft) and KDP-2 (East) is 1,228 meters (4,029 feet). The dock is connected to the shipping channel – Hooghly River, through a lock gate. A section of the dock between the lock gate and KDP-1 is the "tidal basin"; dry docks are connected to this basin. Ships enter the dock through a lock gate. The lock barrel is 176.8 metres (580 ft) long and 24.4 m (80 ft) wide. The depth in front of the lock gate is about to . Accordingly, vessels with a maximum length of 157 meters (515 feet) and a maximum width of 21.35 meters (70 feet) are able to enter the dock. Buoys/moorings installed within the docks provide support to the movement of ships. Kidderpore Dock has several bends, and no night navigation; as a result the ships operate only during the day. Berths are identified by numbers, which can range from 2 to 13. The berths (impounded dock) have uneven water depth, with a minimum of 10 meters (33 ft) in berths No. 2 and No. 10, and a maximum of 12.5 meters (41 ft) in berths other than No. 2 and No. 10. The dock is connected to the Hooghly River, the shipping channel, through a lock-gate. The jetties on the Hooghly River mainly transport liquid products — crude oil, POL products, naphtha, liquefied petroleum gas (LPG) and edible oil. These jetties are known as Haldia Oil Jetty, and are identified by Roman numerals. The water depth is 10 m (33 ft) at the first (HOJ-I) and second (HOJ-II) oil jetties, and 12.5 m (41 ft) at the third (HOJ-III) oil jetty. Recently, a fourth oil jetty, known as Outer Terminal 2, has been constructed between the Dock's Approach Jetty and the Second Oil Jetty (HOJ-II); the water depth at the jetty is 9 m (30 ft). Outer Terminal 1 (OT-1) is located upstream of the third oil jetty (HOJ-III) for the transportation of dry bulk cargo; the jetty has a water depth of 8.5 meters (28 ft) and is capable of anchoring vessels up to in draft. Haldia Anchorage is used for lash vessels. Dry Dock KoPT has the largest dry dock facility in India. These dry docks cater to the diverse repair and maintenance needs of the vessels calling on the Eastern Ports of India. In addition, shipbuilding facilities are also available in these dry docks. All the dry docks are inside the impounded dock system. There are five dry docks of which three are in Kidderpore Dock and two are in Netaji Subhas Dock. There is a fully-fledged repair workshop including Diesel Engine Overhauling Unit, Structural Shop, Heavy and Light Machine Shop, Forging Shop, Electrical Shop and a Chain Testing/Repair Shop with 2500 KN capacity Tensile Compression Testing Machine to support various activities in the dry dock. Electric Level Luffing Cranes of 5 tonne and 7 tonne capacities are used at Dry Dock No. 1 and No. 2 of Kiddirpore Dock respectively, operating area radius of which area 20 m (66 ft) and 25.42 m (83.4 ft) respectively. 4 cranes are used at Netaji Subhash Dock, which includes 1 Electric Level Luffing Crane and 3 Electric Cranes. The Electric Level Luffing Crane has a capacity of 25 tons and a operating area radius of 15.25 m (50.0 ft); on the other hand, 2 of the electric cranes have a capacity of 3 and 6 tons and the other is of 3 ton capacity. == Port channel ==
Port channel
containing information on the navigation of the Hooghly River from Sagar Point to Kolkata, published in 1905 by the United Kingdom Hydrographic Office. The port has a 232 kilometers (144 mi) long shipping channel. Most ships navigating the Channel require a pilot, and the sharp bends and submerged Sandbars of the Channel require the assistance of tugboats for larger ships. The channel extends from the Sandheads area of the Bay of Bengal to the Khidirpur Docks of the Kolkata Dock System in the city of Kolkata; in the 87 km (54 mi) long stretch from the Sandheads to the Sagar Road, where vessels are managed through the Syama Prasad Mukherjee Port Authority's Vessel Traffic Management System. The depth of water in the channel is higher during monsoon than summer. The depth of the channel depends on the flow of water in the Hooghly River. Channel depth is not equal at all locations due to the presence of submerged Sandbars. The channel is 50 m (160 ft) deep at Sandheads and 9 m (30 ft) to 10 m (33 ft) deep at Sagar Road. Navigational Aids Automatic Tide Gauges, and River Marks and Buoys All Automatic Tide Gauges in the channel are operated and maintained by the port. These tide gauges are located near Garden Reach and Diamond Harbor on the east bank of the channel and Haldia on the west bank. For the round-the-clock recording of tidal data, which is used for the prediction of tides and preparation of tide tables by Survey of India. Lighthouse • Sagar Lighthouse is situated at Middleton Point on the Sagar Island inshore. It is visible from a distance of in clear weather. • Dariapur Lighthouse is situated on the right bank of Hooghly River south of Rasulpur river and about inshore. It is visible from a distance of in clear weather. Light Vessels There are five unmanned light vessels, located south of the Sagar lighthouse. These unmanned light-vessels help vessels navigating the channel safely from the sandheads to the Sagar. There are five unmanned light vessels on the south towards of the Sagar lighthouse are the U.G.L.F. located at 21°29′51″N and 88°06′36.5″E, L.G.L.F. located at 21°21'54" N and 088°09'34" E, Talent WK L.V. located at 21°21'54" N and 088°09'34" E, Eastern Channel L.V. located at 21°17'00" N and 088°11'25" E, and Western Channel L.V located at 21°05'002" N and 087°50'24.8" E. Semaphores These are maintained at Akra, Moyapur, Hooghly Point, Balari, Gangra and Sagar for displaying rises of tide for the convenience of various vessels navigating, dredging and surveying in the River Hooghly. The semaphores used to display the tide level at these localities on a mast by the position of the meter and decimeter arms which were manually rotated with the rise and fall of every decimeter of tidal level. However these semaphores are no longer functional and instead, tidal levels are broadcast over VHF radio every half an hour from all the above stations except at Balari. Differential Global Positioning System In the wide estuary, position fixing with reference to shore objects to be viewed from the deck of a vessel, is very difficult. In 1983 KoPT introduced the Electronic Position Fixing System "Syledis" for position fixing of the vessels plying in the wide estuary of the Hooghly River. The shore-based Syledis Position Fixing System was functioning round the clock with the help of the Syledis Stations located at Haldia, Raichak, Dadanpatra Bar and Frazergunj. The system was effectively used for the purpose of hydrographic survey and dredging. KoPT has now replaced the Syledis Position Fixing System by Differential GPS (Differential Global Position Fixing System). This latest state-of the art technology provides improved location accuracy of up to 10 cm. == Connectivity ==
Connectivity
Railway Kolkata Dock System Railway (KDS Railway) KDS Railway was set up to cater to the traffic needs for docks, warehouses in the vicinity and various public and private sidings located around the Kolkata docks system. It works as a terminal agent of Indian Railways and operationally under Sealdah Division of Eastern Railway. KDS Rly has a working Agreement with Eastern Railway and render services to the users on behalf of them. Though KDS railway initially had many interfaces with Eastern Railway/South Eastern Railway and covered a wide range of area including Chitpur, Shalimar, and Garden Reach, at present its operation is truncated in the dock area only with the sole marshalling yard at East Dock Junction (EJC). The total track length of KDS railway is about . It is connected with Eastern Railway through the Majerhat railway station. Indian Railways bring traffic for KDS through full fledged goods trains (rakes) in the East Dock Junction (EJC), by their locomotives. Thereafter KDS railway, after necessary documentation and certain mechanical work, place the trains in the respective handling points (inside docks or private sidings), in full or installments as per operational feasibility. After completion of loading/unloading operation at Sheds/Docks/sidings etc, the rakes are hauled out and outward trains are formed at the marshalling yard (EJC). Again, after documentation, the outward rakes are dispatched by the locomotives provided by Eastern Railway. Road The Kolkata dock system (KDS) is connected to roads under the Kolkata Municipal Corporation. Major congestion and traffic jams are seen on the narrow roads for vehicular movement in and out of the KDS. KDP and NSD are located about 10 km from the junction of National Highway 16 and National Highway 19. The junction of National Highway 12 and Airport Road is about 25 km from the dock area. Diamond Harbor Road, Taratala Road and Garden Reach Road (Peripheral Road) are 4-lane, and have been strengthened and upgraded, but are often congested due to the simultaneous movement of local and cargo traffic. Waterway The Kolkata Dock System and Haldia Dock Complex are directly connected to National Waterway 1, which provides the port with waterway connectivity to North India. This waterway transports goods directly from Port of Kolkata to Varanasi and Sahebganj terminals. Besides, it is connected with the river ports of Bangladesh and North-Eastern Indian state of Assam through National Waterway 97. ==Passenger services==
