The importance of the Suez Canal lies in the increase of commercial exchanges with Asia and its greater fragility, due to the growth of ship size, especially container ships and energy bulk carriers, which cannot pass through other communication routes, such as the Panama canal.
The gigantism of merchant ships has allowed an exponential growth in international trade and, therefore, the reduction of global poverty, logistics costs and greenhouse gas emissions (GHG) per unit or tonne transported. However, it also carries risks, as proved by the recent blockade.
Container ship size: a turning point?
The recent incident involving the ship Ever Given, which blocked the Suez Canal for six days, affecting more than 200 vessels, brings up at least three issues intensely debated in recent years.
The first one refers to the gigantism of ship sizes. Despite its considerable contribution towards greater environmental, operational and financial efficiency in world maritime transport, it also represents a high risk due to the concentration of the cargo from a large part of European exporters and importers in a single ship.
Are we at a tipping point? Will merchant ships stop growing the way they have in the last two decades? Will there be a similar phenomenon to the one experienced by air transport, in which the largest aircraft (A-380) has been discontinued?
As it happened with air transport, maritime transport has long stopped navigating at the maximum possible speed, generating parallelisms between the disappearance of the Concorde and the widespread practice of slow steaming. Could the Ever Given incident in the Suez Canal help to slow, or even stop, the trend to build ever larger ships?
