Cargo ships have been delivering their loads later than ever this year, adding to the supply-chain woes that are undercutting efforts by retailers and manufacturers to capitalize on resurgent economic demand.
Only about 40% of container ships globally were on time arriving at ports in March, according to an analysis by Denmark-based Sea-Intelligence ApS, with average delays stretching to more than six days. The slowdowns improved from February, but remained far behind reliability levels of the previous two years, when more than 70% of ships arrived on time.
The delays around the world, the result of a large-scale restocking by businesses as consumer demand improves, are tying up vessel capacity, adding to a shortage of sea containers needed to move goods and sending shipping costs soaring as container freight rates rise at a historic pace.
For companies shipping goods, the delays are part of an array of headaches disrupting supply chains as U.S., European and Asian economies rebound from the steep retrenchment last year brought on by the Covid-19 pandemic. Rising raw materials costs, shortages of finished goods and components such as semiconductors and lumber, shortfalls in the supply of workers, and capacity crunches in transportation networks have knocked companies off balance as demand across a range of sectors has recovered.
The shipping delays that started building up late last year worsened during a normally slack period in shipping demand early in the year. They have tied up inventories in some cases for weeks at a time as vessels wait to reach berths while offloaded containers sit for long periods at packed freight terminals.
Shipping executives say the greatest delays have been at Southern California’s neighboring ports of Los Angeles and Long Beach. Heavy demand by U.S. importers to restock inventories depleted during the past year’s Covid-19 restrictions has swamped the largest U.S. trade gateway and triggered heavy logjams of ships off the coast.
“It [normally] takes 14 days to sail from Shanghai to Los Angeles; today it takes 33 days,” said Vincent Clerc, chief executive of ocean and logistics at Denmark’s A.P. Moller Maersk A/S, the world’s biggest container operator in terms of capacity. “The sailing time is the same, but you spend twice the time waiting to unload at the San Pedro Bay.”
“We have invested millions of dollars in extra capacity, but a large part of that capacity is immobilized because of congestion in the U.S. West Coast,” Mr. Clerc said.
The delays appear to be the longest at the California ports but Sea-Intelligence said ships moving from Asia to Europe have also been held up past their scheduled arrivals.
Congestion has led to delays of up to six days at sites including Port Klang in Malaysia, Rotterdam in the Netherlands, Piraeus in Greece, Southampton in the U.K. and the Kao-hsiung port in Taiwan.
The cargo delivery delays have stretched from docks to rail yards, truck terminals and distribution centers, leaving everyone from giant retailers and auto manufacturers to mom-and-pop shops short of supplies and paying multiple times more compared with last year to move their merchandise.
The cost of moving a 40-foot sea container from China to U.S. West Coast ports was quoted this week at $5,650, according to the Freightos Baltic Index, up 34.5% since the start of the year and 228% higher than the same period last year.
Delays at the Southern California ports have eased over the past month. The Marine Exchange of Southern California reported fewer than 20 container ships were waiting at anchor for berths during several days over the past week. That was far below the peak of about 40 ships at anchor in the first quarter and marked the lowest levels since last November. Still, the group, which monitors vessel traffic in the region, said there are normally no delays for ships seeking a slot at the Los Angeles and Long Beach docks.
