Shipping containers stacked port

Shipping containers stacked at a busy port, symbol of global trade and modern logistics.

About this subject

Shipping containers are the backbone of international trade, carrying about 90% of the world's non-bulk cargo. Invented by American Malcom McLean in the 1950s, they standardized maritime transport, reducing costs and loading times. A port like Santos in Brazil or Singapore, the world's largest, can handle millions of TEUs (twenty-foot equivalent units) per year. Stacked containers form colorful walls, each color indicating a shipping line: blue for Maersk, orange for Hamburg Süd, green for Evergreen. They are made of corten steel, resistant to corrosion, and can last up to 20 years in heavy use. Besides dry cargo, there are refrigerated models (reefers) for perishable foods and tanks for liquids. The maximum stacking height on ships reaches 11 containers, but on land terminals it can exceed 8 rows, requiring large gantry cranes. Brazil has strategic ports like Paranaguá and Rio Grande, which export agricultural production worldwide. Logistics efficiency depends on container organization, tracked by IT systems that indicate location and contents. Without them, shipping costs would be prohibitive for many products, directly impacting final consumer prices.

Frequently Asked Questions

What is the standard size of a shipping container?

The most common standard sizes are 20 feet (6.06 meters) and 40 feet (12.19 meters) in length. Standard height is 8.5 feet (2.59 meters), but high cube models are 9.5 feet (2.89 meters).

How many containers can a container ship carry?

The largest container ships, like the MSC Irina, can carry over 24,000 TEUs. Smaller feeder ships carry between 1,000 and 3,000 TEUs.

How are containers tracked during transport?

Each container has a unique identification number (BIC) and can be tracked via GPS, IoT sensors, and logistics management systems. Shipping lines update location in real time.
