Ports and Maritime Infrastructure
India's major ports — their old names, their coast and state, their natural-vs-artificial character, and the satellite terminals built to relieve them.
Why this matters
About 8 PYQs, almost all MODERATE recall. The reliable earners are the renamed ports (Deendayal = old Kandla, Kamarajar = old Ennore), each port's coast/state, and the natural-vs-artificial descriptions used in 'identify the port' questions. Memorise the old-name pairs and the signature description of each major port.
Concept 1 of 2
Major ports — old names, states and coasts
Intuition
Two recurring threads: the RENAMINGS and the COAST/STATE. Deendayal Port is the old Kandla Port (Gujarat, west coast). Kamarajar Port is the old Ennore Port (Tamil Nadu, east coast) — built to handle Chennai's thermal coal, and a corporatized public company (an artificial, not a natural, port). Knowing the old name and the home state answers most port questions outright.
Definition
- Deendayal Port = formerly Kandla Port, in Gujarat (west coast).
- Kamarajar Port = formerly Ennore Port, in Tamil Nadu (east coast); built for Chennai's thermal coal; a corporatized public company and an artificial port (NOT natural).
- Mumbai (JNPT) lies on the west coast; Visakhapatnam, Chennai, Paradip, Kolkata on the east.
| Port (new name) | Old name | State / coast |
|---|---|---|
| Deendayal | Kandla | Gujarat, west coast NDA 2023 — Deendayal Port was earlier Kandla. |
| Kamarajar | Ennore | Tamil Nadu, east coast NDA 2026 — Kamarajar is corporatized + ex-Ennore, but NOT a natural port. |
| Jawaharlal Nehru (JNPT) | Nhava Sheva | Maharashtra, west coast |

[Q130 · Apr · 2023]
Kamarajar is artificial, not natural
In multi-statement Kamarajar questions, 'it is a corporatized public company' and 'earlier known as Ennore' are both correct, but 'it is a natural port' is the FALSE clause — Kamarajar/Ennore is an artificial port.
Concept 2 of 2
Identifying ports by their character
Intuition
'Identify the port' questions hand you a description; each major port has a signature. COCHIN — a natural harbour on the west coast, protected by a breakwater and a mole, with a deep ~14 m draft channel. MUMBAI — the biggest port. VISAKHAPATNAM — a land-locked (natural inner) harbour, oldest on the east coast. KOLKATA — a riverine (riverside) port; MORMUGAO — at the entrance of an estuary; PARADIP — in the delta region. Match the description to the signature.
Definition
- Cochin — natural harbour on the west coast, protected by a breakwater + mole, deep ~14 m draft channel.
- Mumbai — the biggest port of India; also called the 'Queen of the Arabian Sea'.
- Visakhapatnam — a land-locked (sheltered inner) harbour, oldest on the east coast.
- Kolkata — a riverside (riverine) port; Mormugao — at the entrance of an estuary; Paradip — in the delta region.
- Vadinar offshore terminal was developed to relieve Kandla (Deendayal) Port.
| Port | Signature description |
|---|---|
| Cochin | West-coast natural harbour; breakwater + mole; ~14 m draft NDA 2024 — this description identifies Cochin Port. |
| Mumbai | Biggest port; Queen of the Arabian Sea |
| Visakhapatnam | Land-locked harbour; oldest on east coast |
| Vadinar terminal relieves | Kandla (Deendayal) Port NDA 2025 — Vadinar reduces pressure on Kandla. |
