CAIRO — An enormous container ship became stuck while traversing the Suez Canal late Tuesday, blocking traffic through one of the world’s most important shipping arteries and threatening to add one more burden to a global shipping industry already battered by the coronavirus pandemic.

The ship, which was heading from China to the port of Rotterdam in the Netherlands, ran aground amid poor visibility and high winds from a sandstorm that struck much of northern Egypt this week, according to George Safwat, a spokesman for the authority that oversees the canal. The storm caused an “inability to direct the ship,” he said in a statement.

By Wednesday morning, more than 100 ships were stuck at each end of the canal, which connects the Red Sea to the Mediterranean and carries roughly 10 percent of worldwide shipping traffic.

Dozens of tugboats raced to try and wrench it free as crews on the land brought heavy equipment to dig out the land where it sat wedged.

Lt. General Osama Rabie, the head of the canal authority, said that the authority was reopening an older section of the canal to allow ships to move through the waterway.

Nearly every vessel traveling from Asia to Europe passes through the 120-mile channel. The Suez is also a corridor for some ships carrying cargo from Asia to the east coast of the United States, as well as a pathway from North Africa to the rest of the world. Only the Panama Canal looms as large in the passage of goods around the globe.

“The Suez Canal will not spare any efforts to restore navigation and to serve the movement of global trade,” General Rabie said in a statement, adding that rescue units and eight tugboats were continuing to try to refloat the stuck vessel on Wednesday morning.

If the authorities in Egypt are able to free the vessel from the bottom of the channel and move it to the side of the waterway within two to three days, the episode will be a minor inconvenience to the industry. Shipping companies generally build in extra days to their schedules to account for delays en route.

But if the ship’s extraction proves more complex, leaving the Suez blocked for longer, that could pose a substantial risk for an industry that is already overwhelmed. Global maritime trade has taken a hit over the last year because of the pandemic, pushing Egypt’s revenues from the canal down 3 percent to $5.61 billion in 2020.

“If that’s going to be a knock-on delay, then you’ll see piling up and bunching up of ships on their arrival in Europe as well,” said Akhil Nair, vice president of global carrier management at SEKO Logistics in Hong Kong. “It’s just one more factor that we didn’t need.”

Pictures from the canal showed the container-laden ship — the Ever Given, which is almost a quarter of a mile long — sitting sideways across the canal at such an angle that the name of the company that operates it, Evergreen, is clearly readable from the ship behind it. Its bow appeared to be stuck on the canal’s rocky eastern bank.

“Ship in front of us ran aground while going through the canal and is now stuck sideways,” an Instagram user named @fallenhearts17 posted on Tuesday evening. “Looks like we might be here for a little bit …”

The Suez Canal is a key artery for oil flows from the Persian Gulf region to Europe and North America. Roughly 5 percent of globally traded crude oil and 10 percent of refined petroleum products passed through the canal before the pandemic, estimated David Fyfe, chief economist at Argus Media, a market research firm.

After the canal was snarled, there was a 2.85 percent jump in the price of Brent crude, the international benchmark, on Wednesday to $62.52 a barrel.

But Mr. Fyfe said that because the demand for oil remained relatively weak amid the pandemic, a short-term outage is unlikely to have a lasting impact on the market.

“I don’t think this is going to fundamentally change market sentiment,” he said. “A lot will depend on how quickly they can get the vessel cleared.”
