Dagli anni '50 alla nuova Triple E, capace di trasportare 18.000 TEU. L'evoluzione delle portacontainer raccontata da William Kremer.
Whist is blue, a quarter of a mile long, and taller than London's Olympic stadium?
The answer - this year's new class of container ship, the Triple E. When it goes into service this June, it will be the largest vessel ploughing the sea.
Each will contain as much steel as eight Eiffel Towers and have a capacity equivalent to 18,000 20-foot containers (TEU).
If those containers were placed in Times Square in New York, they would rise above billboards, streetlights and some buildings.
Or, to put it another way, they would fill more than 30 trains, each a mile long and stacked two containers high. Inside those containers, you could fit 36,000 cars or 863 million tins of baked beans.
