Cargo ship horizon

Cargo ship on the maritime horizon, symbol of global trade and modern naval engineering.

About this subject

Cargo ships are the backbone of international trade, carrying about 90% of the world's goods. These large vessels, such as container ships, can exceed 400 meters in length and carry over 20,000 containers. The maritime horizon, where the ship appears to float between sky and sea, evokes the vastness of oceanic routes connecting continents. The busiest route connects Asia to Europe via the Suez Canal, but there are also routes through the Panama Canal and around the Cape of Good Hope.

The shipping industry has evolved significantly since the first steamships. Modern cargo vessels use highly efficient low-speed diesel engines and satellite-based navigation systems. The largest cargo ship ever built, the MSC Irina, has a capacity of 24,346 TEUs (twenty-foot equivalent units). These giants cruise at an average speed of 16 to 25 knots, and a voyage from Shanghai to Rotterdam takes about 30 days.

The horizon in this context also represents the limit of naked-eye visibility, which for an observer 10 meters above sea level is about 11 kilometers. Crew members of cargo ships often spend months at sea, calling at ports in different countries. The COVID-19 pandemic highlighted the vulnerability of supply chains, with port congestion and rising freight rates. Today, the industry seeks to reduce carbon emissions, testing alternative fuels such as LNG and ammonia.
