WHAT IS PORT ?
A port is a facility for receiving ships and transferring cargo. They are usually found at the edge of an ocean, sea, river, or lake. Ports often have cargo-handling equipment such as cranes (operated by longshoremen) and forklifts for use in loading/unloading of ships, which may be provided by private interests or public bodies. Often, canneries or other processing facilities will be located near by. Harbour pilots and tugboats are often used to maneuver large ships in tight quarters as they approach and leave the docks. Ports which handle international traffic have customs facilities.
The terms "port" and "seaport" are used for ports that handle ocean-going vessels, and "river port" is used for river traffic, such as barges and other shallow draft vessels. Some ports on a lake, river, or canal have access to a sea or ocean, and are sometimes called "inland ports". A "fishing port" is a type of port or harbor facility particularly suitable for landing and distributing fish. A "dry port" is a term sometimes used to describe a yard used to place containers or conventional bulk cargo, usually connected to a seaport by rail or road. A "warm water port" is a port where the water does not freeze in winter. Because they are available year-round, warm water ports can be of great geopolitical or economic interest, with the ports of Saint Petersburg and Valdez being notable examples. A "port of call" is an intermediate stop, for example to collect supplies or fuel.
Cargo containers allow efficient transport and distribution by eliminating loading of smaller packages at each transportation point, and allowing the shipping unit to be sealed for its entire journey. Standard containers can easily be loaded on a ship, train, truck, or airplane, greatly simplifying intermodal transfers. Cargo often arrives by train and truck to be consolidated at a port and loaded onto a large container ship for international transport. At the destination port, it is distributed by ground transport
THE MAJOR PORTS IN THE WORLD IS:-
As we know that the world is made of 33% land and 66% water it menas most of the land area is surrounded by water,so there is so many ports in the world some the major ports are Singapore,Bostan,New York,Dubai,Bombay,Los angles,Durban,VIGO,Hong kong etc.
MAJOR PORTS IN INDIA:-
The management and development of the major ports in the country are controlled by the central government through respective port trusts. Minor ports are controlled by state governments.
• India currently has 12 major ports and 184 minor /intermediate ports spread across the vast coastline of 7517 kms. They handle almost 90 per cent of India’s total foreign trade.
• The total cargo volume handled by major ports has increased from around 157.5 million tonnes in 1992 to over 288 million tonnes in 2001-02. This accounts for almost 76 per cent while the remaining 24 per cent is handled by the minor ports. Liquid and dry bulk cargo constitutes about 83 per cent of the total volume of traffic handled. Container and general cargo comprise the remaining.
• The current handling capacity of the major ports in the country is around 344 million tonnes. This has been achieved through construction of a new port at Ennore and a mechanised coal handling facility at Paradip. These two facilities entailed an investment of around US$ 394 million.
(INDIA’S MAJOR PORTS)
India has eleven major sea ports: Kandla, Bombay, Nhava Sheva, Marmagao, New Mangalore, and Kochi (formerly known as Cochin) on the west coast, and Calcutta-Haldia, Paradip, Vishakhapatnam, Madras, and Tuticorin on the east coast. The port at Nhava Sheva, located across the harbor from Bombay Port, was established in 1982 under the administration of the Jawaharlal Nehru Port Trust as a separate port rather than an adjunct to Bombay. The eleven ports in India are the responsibility of the Ministry of State for Surface Transport but are managed by semi-independent port trusts overseen by boards appointed by the ministry from government departments, including the navy, port labor and industry, and ship owners and shipping companies.

1).Chennai (oldest and artificial):-
History:-
Chennai Port, is more than a century old artificial port, and located in Chennai, South India, is one of the major ports on the Coromandel coast of India. The initial piers were built in 1861, but the storms of 1868 and 1872 made them inoperative. So the Masonry work for L shaped breakwaters was started in 1876, but the storm of 1881 completely washed the almost completed harbour. The Chennai Port Trust has taken the year of rebuilding 1881 as the starting year and is now celebrating its 125th anniversary. The port's quays (berths) were constructed at different periods — the South Quay I in 1913, the five West Quay berths between 1916 and 1920, the North Quay in 1931 and the South Quay II in 1936, in the Inner Harbour, later christened Dr Ambedkar Dock.
From 1881 to 1945, the cargo handled in Madras port varied from 0.5 million tonnes to 1 million tonnes. By 1979-80, the traffic touched 10 million tonnes, and increased to 15 million tonnes in 1984-85. By 1991-92, the volume was 25 million tonnes, touching 41 million tonnes in 2000-01. Though there was a slump in the next three years, the port recovered, to handle 47.25 million tonnes in 2005-06. In the current fiscal, the cargo handled is expected to cross 50 million tonnes. The car exports from this port are expected to touch 300,000 by 2008.
Operations
Chennai Port has 21 alongside berths in the 3 Docks viz., Dr.Ambedkar Dock, satabt Jawahar Dock, Bharathi Dock and Container Terminal. Chennai Port handles a variety of cargo including iron ore, coal, granite, fertilizers, petroleum products, containers, automobiles and several other types of general cargo items. Due to the increase in container traffic, its second container terminal is being planned based on a build and operate model. [2] It has asked for support for a mega container terminal. The terminal would be the first deep water terminal of its kind in India and would be able to handle ultra-large container ships of 13,000-15,000 TEUS capacity and length exceeding 400 metres[3]. The management of the container terminal was taken over by P&O Ports of Australia. This has a volume growth of 20% per year and has 59% of the market share of South India. It has services to Singapore, Malaysia, Thailand, Myanmar, Sri Lanka, Korea, China, Mediterranean, Europe, Australia and the US.
2)KOLKATA PORT:-
Port of Kolkata is a riverine port in the city of Kolkata, India. It is the oldest operating port in India, having originally been constructed by the British East India Company.
The Port has two distinct dock systems - Kolkata Docks at Kolkata and a deep water dock at Haldia Dock Complex, Haldia.
In the 19th century Kolkata Port was the premier port in British India. After independence its importance decreased because of factors including the Partition of Bengal (1947), reduction in size of the port hinterland and economic stagnation in eastern India. In the 21st century due to the east Indian economic recovery and infrastructure improvements, the port grew swiftly to become the nation's second largest container port. It was one of India's fastest growing ports in 2004-05.

3) MANGLORE PORT:-
Sea entrance to Mangalore Harbour
New Mangalore Port known by the name of New Mangalore Port Trust ( NMPT ) is the only major port of Karnataka and is currently the ninth largest port in India. It was formally inaugurated on May 4, 1974 by the then prime minister Indira Gandhi. The construction began in 1962. The port is situated at Panambur, Mangalore on the west cost of India.It is situated to north of confluence of Gurupura( Phalguni ) river to Arabian sea .It is 170 nautical miles (310 km) south of Mormugao Port & 191 nautical miles (354 km) north of Kochi Port. The port situated in Panambur is called New Mangalore Port, as there is an old harbour or port located in Mangalore city which is called by Mangalore bunder or Hale bunder. The old harbour is located to south of New mangalore port. Old port is now being used for fishing and for ferrying small goods.
The national highway 17 ( NH-17 )passes adjoining the port. The nearest railway station is Thokur, but passengers have to alight at Suratkal Railway station which is on Konkan railway route .The Surathkal railway station is approximately 6 kilometres from the New Mangalore port.
The port serves hinterland of Karnataka state and to some extent state of Kerala. The major commodities exported through the port are Iron Ore concentrates & pellets, Iron Ore fines, manganese,granite stones, coffee,cashew and containerized cargo. The major imports of the port are crude and petroleum products, LPG, wood pulp, timber logs, finished fertilizers, liquid ammonia, phosphoric acid, other liquid chemicals, containerized cargo, etc.
4) GOA:-
At the time of its commissioning in 1888, the Mormugao Port comprised of 3 berths along with a breakwater having a length of 358 meters. As the years rolled by, the infrastructure slowly kept growing. By 1922, Berths 4 and 5 were built and the breakwater was extended to its present length of 522.40 meters. A mole of 270 meters was added.
Mormugao Port, went through a fair amount of change as the emphasis shifted to development of infrastructure. A couple of years after liberation, the port was delinked from the Railway management. The main railway section from Vasco da Gama to the border of Goa was transferred to the Southern Railways. The Port however, operated its own railway system between Vasco da Gama interchange point and the harbour area.
DEVELOPMENT AND OPERATION
Major developments of the Port were taken up only after it became a Major Port. A number of developmental projects were implemented under the various Five Year Plans of the Government of India. Consequently, a dedicated mineral oil berth, berth No. 8 was constructed in 1976. Later on as the general cargo traffic was gradually picking up in the Port, a number of schemes were implemented with a view to augment the general cargo handling facilities at the Port. Two multi-purpose general cargo berths, berth No.10 and No. 11 having draft of 11.00 mts and 12.50 mts were constructed and commissioned in 1985 and 1994 respectively. Meanwhile the Mechanical Ore Handling Plant installed in 1959 at Berth No. 6 was de-commissioned in 1992 due to obsolesce. The age old berths 1 to 3 were leased out to a private company, Western India Shipyard Ltd, for installing a modern ship repair facility, which was commissioned in 1995. In 1997, the metre guage railway of the Port linking to the south Central Railway was converted to broad guage. By this, the Mormugao Port is now accessible for any part of the country through the broad guage railway system.
5) Visakhapatnam Port:-

The port has a humble saga of contributing significantly to the international maritime transport for the past 50 years. As a humble beginning in year by the great visionary the late Maharao Khengarjii (3) of the princely state of Kutch for a deep draught closed port in his kingdom, the port of Kandla came into existence in the year 1931 with a single pier construction.
Due to the loss of Karachi port after the post independence period the onus of entire Indian Port was shifted putting tremendous strain on Mumbai port facilities. Under the inspirational leadership of the iron man of India – Sardar Vallabhai Patel, the Indian Government on 17 Feb. 1948 constituted an expert committee known as the Western Coast Major Port Development Committee to explore the possibilities of establishing a deep sea port to cater the vast hinterland comprising the north western states of India.

A TUG BOAT:-
A tugboat, or tug, is a boat used to maneuver, primarily by towing or pushing, other vessels (see shipping) in harbors, over the open sea or through rivers and canals. Tugboats are also used to tow barges, disabled ships, or other equipment like oil platforms.
Tugboats are quite strong for their size. Early tugboats had steam engines (see steamboat); today diesel engines are used. Tugboat engines typically produce 750 to 3,000 horsepower (500 to 2,000 kW), but larger boats (used in deep waters) can have power ratings up to 25,000 hp (20,000 kW) and usually have an extreme power:tonnage-ratio (normal cargo and passenger ships have a P:T-ratio (in kW:GRT, of 0.35-1.20, whereas large tugs typically are 2.20-4.50 and small harbour-tugs 4.0-9.5). The engines are often the same as those used in railroad locomotives, but typically drive the propeller mechanically instead of converting the engine output to power electric motors, as is common for railroad engines. For safety, tugboats' engines often feature two of each critical part for redundancy.[citation needed]
A tugboat's power is typically stated by its engine's horsepower and its overall Bollard pull.
Tugboats are highly maneuverable, and various propulsion systems have been developed to increase maneuverability and increase safety. The earliest tugs were fitted with paddle wheels, but these were soon replaced by propeller-driven tugs. Kort nozzles have been added to increase thrust per kW/hp. This was followed by the nozzle-rudder, which omitted the need for a conventional rudder. The cycloidal propeller was developed prior to World War II but was only occasionally used in tugs because of its maneuverability. After World War II it was also linked to safety due to the development of the Voith Water Tractor, a tugboat configuration which could not be pulled over by its tow. In the late 1950s, the Z-drive or (azimuth thruster) was developed. Although sometimes referred to as the Schottel system, many brands exist: Schottel, Z-Peller, Duckpeller, Thrustmaster, Ulstein, Wärtsilä, etc. The propulsion systems are used on tugboats designed for tasks such as ship docking and marine construction. Conventional propeller/rudder configurations are more efficient for port-to-port towing.
