TEU and FEU Explained
To understand how many 40-foot containers fit on a cargo ship, we need to talk about TEUs and FEUs.
TEU (Twenty-Foot Equivalent Unit) is a standard measurement used to describe the capacity of cargo ships. One TEU represents the size of a standard 20-foot container.
FEU (Forty-Foot Equivalent Unit) is another measurement, representing the size of a 40-foot container. One FEU is equivalent to two TEUs.
Quick Conversion:
– 1 TEU = 20-foot container
– 1 FEU = 40-foot container = 2 TEUs
Container Sizes and Ship Design
Cargo ships are designed to carry containers of various sizes. Most ships use a combination of TEUs and FEUs to maximize space.
Modern Cargo Ships:
– Capacity: Up to 24,000 TEUs
– Design: Ships are built with slots to hold containers securely in place. These slots can fit both 20-foot and 40-foot containers.
Cargo Volume and Weight Limits
The total capacity of a cargo ship depends on both the volume and weight of the containers.
Volume:
– A ship’s capacity is measured in TEUs. For example, a ship with a capacity of 24,000 TEUs can carry up to 12,000 FEUs.
Weight Limits:
– Each container has a maximum weight limit. For a 40-foot container, this is around 26,500 kg. Ships must balance the number of containers with weight limits to ensure safe and efficient transport.
Understanding these basics helps you see how cargo ships maximize space and efficiency in global trade.
Next, let’s explore how many 40-foot containers fit on modern cargo ships and what influences their capacity.
