Container ship cargo ocean

Container ships carry over 80% of global trade, connecting continents with logistical efficiency.

About this subject

Container ships are the backbone of international trade. Since Malcolm McLean introduced the modern container in the 1950s, maritime transport has undergone a revolution. Today, the largest vessels, like the Maersk Triple E class, can carry over 18,000 TEUs (Twenty-foot Equivalent Units) and measure about 400 meters in length. They operate on fixed routes, such as Asia-Europe via the Suez Canal and the Transpacific, linking major ports like Shanghai, Singapore, and Rotterdam. The efficiency of these ships enabled the globalization of production costs, but also brought challenges: port congestion, carbon emissions (though new models use LNG and rotor sails), and piracy risks in areas like the Gulf of Aden. Logistics involves complex tracking systems and automated terminals, where gantry cranes load and unload containers in hours. The sector handles about $12 trillion in cargo annually, with 90% of non-commodity world trade carried by sea.

Frequently Asked Questions

What is the largest container ship in the world?

Currently, the MSC Irina is the largest, with a capacity of 24,346 TEUs and 399.9 meters in length.

How long does it take to unload such a ship?

At modern terminals, unloading can take 24 to 48 hours, depending on the number of cranes and organization.

What is the environmental impact of cargo ships?

They emit about 3% of global greenhouse gases, but new IMO regulations require a 50% reduction by 2050, driving alternative fuels.
