Container ship cargo ocean

Container ships form the backbone of global trade, carrying billions of tons of cargo across oceans each year.

About this subject

Container ships are vessels designed exclusively for transporting standardized containers, enabling efficient movement of goods across ship, rail, and truck modes. These sea giants can exceed 400 meters in length and carry over 24,000 containers (TEU). The largest examples, such as the MSC Irina or Ever Alot class, have capacities above 24,000 TEU and require deep-water ports.

The container revolution began in the 1950s, pioneered by American entrepreneur Malcolm McLean. Previously, cargo was loaded as crates and sacks, a slow and expensive process. Standardization drastically reduced loading and unloading times from days to hours. Today, about 90% of global trade by volume is transported by ship, with container ships accounting for the majority of this flow.

These ships operate on fixed routes, connecting major ports like Shanghai, Singapore, and Rotterdam. Brazil has important terminals such as Santos and Paranaguá, which receive large vessels. Average cruising speed is around 20 to 25 knots, and fuel consumption can reach 200 tons per day. The industry is seeking more sustainable alternatives, such as LNG-powered engines and rotor sails, to reduce carbon emissions.

Frequently Asked Questions

What is the largest container ship in the world?

Currently, the largest are the MSC Irina and Ever Alot classes, with capacity exceeding 24,000 TEU. For instance, MSC Irina is 399.9 meters long and 61.5 meters wide.

How many containers can such a ship carry?

The largest can carry over 24,000 twenty-foot equivalent units (TEU). In practical terms, this equals thousands of tons of cargo, ranging from electronics to food.

How do these ships affect the environment?

They emit large amounts of CO2, sulfur oxides, and particulate matter. The maritime industry is reducing impacts with cleaner fuels like LNG and energy efficiency technologies.
