Introduction to Cargo Shipping

Cargo shipping accounts for over 90% of global trade, with containerized goods being the most popular method. The ability to stack and transport 40ft containers efficiently has revolutionized logistics, but understanding how many can fit on a ship requires considering ship design, cargo weight, and safety standards.

What Influences Container Capacity?

Ship Size and Design

Container ships come in various sizes:

• Feeder Ships handle regional transport and typically hold up to 1,000 TEU (Twenty-foot Equivalent Units).
• Ultra Large Container Ships (ULCS) are massive vessels with capacities exceeding 24,000 TEU.

A 40ft container is equivalent to 2 TEU, which directly affects the total container count.

Container Weight Restrictions

• Maximum Payload: The standard 40ft container has a maximum gross weight of around 30.48 metric tons.
• Stability and Safety: Ships are designed to balance container weight across decks and hold areas, which can limit the number of containers even if space allows.
