Major ports of the west coast

Detail

Key terms used in this section

• Port: a place on the coast where ships load and unload cargo and passengers. It has berths, cranes, storage and rail and road links.
• Major port: a port run by the Union Government through a Port Authority, under the Ministry of Ports, Shipping and Waterways. India has 12 Major Ports (FY 2025-26) [5]. State governments run the other ports, called non-major ports.
• Natural harbour: a stretch of water that is sheltered from waves and wind by the shape of the coast, such as a bay, estuary or lagoon. Ships can anchor safely there with little building work.
• Tidal port: a port where large ships depend on the high tide (the daily rise in sea level) to get enough water depth to enter and leave.
• Hinterland: the inland area that a port serves. The port sends this area's goods out and brings in the goods it needs.
• Satellite port: a new port built near an older, crowded port to take part of its traffic.
• Container port: a port that handles goods packed in standard steel boxes (containers). Container traffic is counted in TEU (twenty-foot equivalent unit: one 20-foot container).
• Transshipment: moving cargo from one ship to another at a middle port, for example from a big ocean "mother ship" to smaller "feeder" ships.

Deendayal Port (Kandla), Gujarat

• Location: a tidal port at the head (inner end) of the Gulf of Kachchh, on the Arabian Sea.
• Why it was built:
• At Partition (1947), Karachi, the main port of north-west British India, went to Pakistan.
• The north-western hinterland was left without a port, and Mumbai had to carry too much traffic.

• Kandla became the first port developed after Independence. It was built to replace Karachi and to take pressure off Mumbai.

• Cargo: designed to handle very large volumes of petroleum, petroleum products and fertiliser.

• Vadinar: an offshore oil terminal in the Gulf of Kachchh. Large tankers unload crude oil there through pipelines, without coming into the shallow port.
• Hinterland: the grain-growing and industrial belt of Jammu and Kashmir, Himachal Pradesh, Punjab, Haryana, Rajasthan and Gujarat.
• Current position:
• In FY 2024-25, Deendayal and Paradip became the first Major Ports ever to handle more than 150 million tonnes of cargo [3].
• In FY 2025-26, Deendayal was the top Major Port by cargo, with 160.11 MT. Paradip (156.45 MT) was second and JNPA (102.01 MT) was third [2].
• In FY 2025-26 it was also the fastest Major Port to reach 100 million tonnes [9].

Mumbai Port, Maharashtra

• Nature: a natural, well-sheltered harbour. Mumbai Island and the mainland protect it from the open sea.
• History: it grew as the main gateway for colonial trade (cotton, textiles) and was historically India's biggest port.
• Position: it is close to the sea routes to West Asia, the Mediterranean, North Africa, North America and Europe.
• Size (NCERT): 20 km long and 6-10 km wide, with 54 berths and India's largest oil terminal.
• Hinterland: Maharashtra, Madhya Pradesh, Gujarat, Uttar Pradesh and parts of Rajasthan.
• Problem: the port is inside a crowded city. It has little land to expand and its roads are congested. This is why a satellite port was needed.

Jawaharlal Nehru Port (Nhava Sheva), Maharashtra

• Built in 1989 as a satellite port to decongest Mumbai Port. It lies across the harbour from Mumbai.
• It is India's largest container port:
• It handled a record 7.3 million TEUs in FY 2024-25, a 13.5% growth over the year before [3].
• It is described as India's largest port with a container capacity of more than 10 million TEUs [8].

• In FY 2025-26 it handled 102.01 MT of cargo, the third-highest among Major Ports. Its growth of 10.74% was also the third-highest [2].

• Links inland: it is the western end of the Western Dedicated Freight Corridor (a rail line only for goods trains, running from the north-west towards Mumbai). The Atal Setu (Mumbai Trans Harbour Link) sea bridge connects it to Mumbai city.

• Next step, Vadhavan Port:
• The Union Cabinet approved it on 19 June 2024. It is an all-weather, greenfield (built on new land, not an expansion of an old site), deep-draft port in Palghar district, Maharashtra [4].
• Cost: ₹76,220 crore. It is being built by a company (SPV) owned 74% by JNPA and 26% by the Maharashtra Maritime Board [4].
• Depth: it has about 20 m of natural water depth close to the shore, so it can take the largest ships [4].
• Capacity: 298 million tonnes a year, including about 23.2 million TEUs. When it is finished it is expected to be among the top ten ports of the world [4].

Mormugao Port, Goa

• Nature: a natural harbour at the mouth of the Zuari estuary (the wide tidal mouth of the Zuari river) in Goa.
• 1961: the port was remodelled to export iron ore to Japan.
• It is India's premier iron-ore exporting port (NCERT: about half of India's iron ore exports; this is an old figure).
• Hinterland: the Konkan Railway (a coastal railway between Maharashtra and Karnataka) extended it to Goa, Karnataka and southern Maharashtra.
• Current position: in FY 2025-26 it handled 21.01 million tonnes, its highest in five years. Its growth of about 16% was the highest among all 12 Major Ports [5][2].
• Its capacity was 63.40 MTPA (million tonnes per annum) as of March 2023 [6].

New Mangalore Port, Karnataka

• Main export: iron ore and iron ore concentrates from the Kudremukh mines in the Western Ghats of Karnataka. The ore was sent down to the coast as slurry (finely ground ore mixed with water and pumped through a pipeline).
• Other cargo: fertilisers, petroleum products, edible oils, coffee, tea, wood pulp, yarn, granite stone and molasses.
• Hinterland: mainly Karnataka.
• Capacity: 114.96 MTPA as of March 2023 [6].

Cochin Port (Kochi), Kerala

• Nature: a natural harbour at the head of Vembanad Kayal. A kayal is a backwater lagoon: a coastal lake of salty water, partly cut off from the sea by sand bars.
• Called the "Queen of the Arabian Sea".
• Position: close to the Suez-Colombo sea route. This is the main shipping lane between Europe and East Asia through the Suez Canal and past Sri Lanka.
• Hinterland: Kerala, southern Karnataka and south-western Tamil Nadu.
• Vallarpadam International Container Transshipment Terminal (2011):
• It was planned as India's first transshipment terminal and is run by DP World [7].

• Why it matters: much of India's container cargo used to be moved between ships at foreign hubs such as Colombo. A home terminal saves time and money.

• Capacity: 79.90 MTPA as of March 2023 [6].

• Nearby: the Vizhinjam port (Kerala) received its first mother ship in 2024. It is described as India's first deep-water container transshipment port [10].

How the west coast ports changed over time

• Colonial period: Mumbai and Karachi were the main ports. They exported raw cotton and other raw materials and imported British manufactured goods.
• After Independence (1947 onwards):
• Kandla was built after Karachi was lost.
• Mormugao was remodelled (1961) for iron ore exports to Japan.

• New Mangalore was built for the Kudremukh iron ore.

• Around and after liberalisation (1991 onwards):

• JNPT opened in 1989, as container trade grew.

• Vallarpadam opened in 2011, with private terminal operation.

• Present day:

• All Major Ports together handled 915.17 MT in FY 2025-26, up 7.06%, against a target of 904 MT [2]. In FY 2024-25 the total was about 855 MT [3].
• POL (petroleum, oil and lubricants) was the largest cargo group in FY 2024-25, with 254.5 MT (29.8%). Containers came next with 193.5 MT (22.6%) [3]. This is why west coast oil ports such as Deendayal and Vadinar, and container ports such as JNPA, lead the list.

Prelims Hooks

• First port developed after Independence: Deendayal (Kandla), a tidal port at the head of the Gulf of Kachchh. Its offshore oil terminal is at Vadinar.
• Top Major Port by cargo in FY 2025-26: Deendayal (160.11 MT), followed by Paradip (156.45 MT) and JNPA (102.01 MT) [2].
• Largest container port: Jawaharlal Nehru Port (Nhava Sheva, 1989), a satellite port of Mumbai. It handled 7.3 million TEUs in FY 2024-25 [3].
• Highest growth among the 12 Major Ports in FY 2025-26: Mormugao (about 16%) [5].
• Port–estuary/lagoon pairs: Mormugao – Zuari estuary; Cochin – Vembanad Kayal.
• "Queen of the Arabian Sea" = Cochin. Vallarpadam (2011) = India's first container transshipment terminal [7].
• Kudremukh iron ore goes out through New Mangalore, not Mormugao (a common trap).
• Vadhavan (Palghar, Maharashtra): a greenfield deep-draft Major Port with about 20 m natural draft, approved in 2024 [4].
• North to south: Deendayal → Mumbai/JNPA → (Vadhavan is north of Mumbai) → Mormugao → New Mangalore → Cochin.

Mains Points

• Partition shaped the ports
• Losing Karachi in 1947 cut off the north-western hinterland from the sea.
• Kandla was built to fill this gap.

• Today Deendayal is India's top cargo port, mainly because of crude oil imports for the refineries of Gujarat and north-west India [2][3].

• Hinterland and connectivity decide a port's success

• The Konkan Railway widened Mormugao's hinterland.
• The Western DFC and Atal Setu feed JNPA.

• Poor inland links, not the coast itself, often limit a port. GS-III: infrastructure and logistics cost.

• Port congestion leads to satellite ports and deep-draft ports

• Mumbai became crowded, so JNPT was built (1989).
• JNPT is now running near full capacity, so Vadhavan is being built, with 20 m draft and 23.2 million TEUs [4].

• Deep water lets India handle the largest container ships and cut its dependence on foreign transshipment hubs (Vallarpadam, Vizhinjam) [7][10].

• Commodity-specific ports are exposed to risk

• Mormugao and New Mangalore grew on iron ore exports.
• Mining bans and the closure of Kudremukh mining show the risk of depending on one commodity. These ports now try to handle a wider mix of cargo [5].
