A serious hangover from last month’s Suez Canal blockage is hectic rescheduling at the world’s container terminals.

Weeks after the refloating of the 20,388-teu Ever Given (built 2018), the biggest container terminals are having to rejig their schedules with up to 100 changes per day, according to Danish liner consultancy Portchain.

While many terminals are now sorting through containership bunching either manually or on spreadsheets, Portchain is trying to convince carriers and terminals that it can sell them a more ­efficient solution in the form of artificial intelligence (AI).
