Suez Canal Is Open, but the World is Still Full of Giant Container Ships

The growth of the shipping industry and ship size has played a central role in creating the modern economy, helping to make China a manufacturing powerhouse and facilitating the rise of everything from e-commerce to retailers like Ikea and Amazon. To the container lines, building bigger made sense: Larger ships allowed them to squeeze out savings on construction, fuel and staffing.

“Ultra Large Container Vessels (U.L.C.V.) are extremely efficient when it is about transporting large quantities of goods around the globe,” Tim Seifert, a spokesman for Hapag-Lloyd, a large shipping company, said in a statement. “We also doubt that it would make shipping safer or more environmentally friendly if there would be more or less-efficient vessels on the oceans or in the canals.”

A.P. Moller-Maersk said it was premature to blame Ever Given’s size for what happened in the Suez. Ultra-large ships “have existed for many years and have sailed through the Suez Canal without issues,” said Palle Brodsgaard Laursen, the company’s chief technical officer, said in a statement on Tuesday.

But the growth in ship size has come at a cost. It has effectively pitted port against port, canal against canal. To make way for bigger ships, for example, the Panama Canal expanded in 2016 at a cost of more than $5 billion.

That set off a race among ports along the East Coast of the United States to attract the larger ships coming through the canal. Several ports, including those in Baltimore, Miami and Norfolk, Va., began dredging projects to deepen their harbors. The Port Authority of New York and New Jersey spearheaded a $1.7 billion project to raise the Bayonne Bridge to accommodate mammoth ships laden with cargo from Asia and elsewhere.

The race to accommodate ever-larger ships also pushed ports and terminal operators to buy new equipment. This month, for example, the Port of Oakland erected three 1,600-ton cranes that would, in the words of one port executive, allow it to “receive the biggest ships.”

But while ports incurred costs for accommodating larger ships, they didn’t reap all of the benefits, according to Jan Tiedemann, a senior analyst at Alphaliner, a shipping data firm.
