Types of Port

Ports are classified in three main ways: by the type of cargo they handle, by their location relative to the sea, and by the specialised function they serve. Each classification helps us understand the port's role in global trade.

Classification by Cargo Handled

This is the most basic way to sort ports, based on what kind of goods move through them.

• Industrial Ports: These ports specialise in handling bulk cargo — large, unpackaged quantities of raw materials. Common examples include grain, sugar, ore, oil, and chemicals. Their entire design is geared toward loading and unloading these heavy, uniform commodities efficiently.
• Commercial Ports: These ports handle general cargo, which consists of packaged products and manufactured goods. Unlike industrial ports, they also manage passenger traffic. They are the typical ports for finished consumer goods.
• Comprehensive Ports: These are the giants of the port world. They handle both bulk cargo and general cargo in very large volumes. Most of the world's great ports fall into this category because their size and facilities allow them to serve every kind of shipping need.

Classification by Location

This classification looks at where a port is physically situated.

• Inland Ports: These ports are located away from the sea coast, deep inside a country. They are connected to the ocean by a river or a canal. Because of this, they are only accessible to flat-bottomed ships or barges, which can navigate shallow or narrow waterways.
  • Examples: Manchester (linked to the sea by a canal), Memphis (on the Mississippi River), Mannheim and Duisburg (on the Rhine River), and Kolkata (on the Hoogli River, a branch of the Ganga).
• Out Ports: These are deep-water ports built away from the main port, usually closer to the open sea. They serve as a solution for the parent port when that port is too shallow or narrow for very large ships. The out port receives these large vessels that cannot approach the main port.
  • Classic example: Athens and its out port, Piraeus, in Greece.

Classification by Specialised Functions

This classification groups ports by the specific, unique role they play in maritime trade.

• Oil Ports: These ports are dedicated to the processing and shipping of oil. They come in two types: tanker ports (where oil is loaded onto tankers for transport) and refinery ports (where oil is refined before shipping).
  • Examples: Maracaibo (Venezuela), Esskhira (Tunisia), and Tripoli (Lebanon) are tanker ports. Abadan on the Persian Gulf is a refinery port.
• Ports of Call: These ports originally developed as simple stopping points on major sea routes. Ships would anchor here to refuel, take on fresh water, and stock up on food. Over time, many of these grew into full-fledged commercial ports.
  • Examples: Aden, Honolulu, and Singapore.
• Packet Station (Ferry Ports): These ports are exclusively concerned with transporting passengers and mail across short stretches of water. They are also called ferry ports. They occur in pairs, with each port facing the other across the water body. …
