"This now looks like it will take a few weeks," said Anoop Singh, the Singapore-based head of tanker analysis at shipping broker Braemar ACM.
Dredgers were working again Friday morning to remove hundreds of thousands of cubic feet of sand around the bow of the 1,300-foot Ever Given, operated by Taiwan-based Evergreen Group, in order to reach a water depth of roughly 50 feet needed to remove the ship, according to the Suez Canal Authority.
People familiar with the rescue effort said the dredgers would likely stop working Friday afternoon when tugboats would return to the site at 4 p.m. local time to try to refloat the ship, though those plans could change. A spokesperson for SCA said it would issue an update later Friday.
An executive at the parent company of ship-owner, Shoei Kisen Kaisha Co., said during a press conference in Tokyo that they aim to dislodge the ship by Saturday night Japan time. "We're prioritizing to unground the ship so that the blockage of the canal can be dissolved," he said.
More diggers are being brought in and salvage teams are making plans to siphon out fuel and ballast water to lighten the ship, according to one person involved in the operation.
"It's a difficult process. The ship's bow is still wedged in the canal wall and there could be some structural damage," this person said. "If you try to yank it out, things could get worse and fuel could spill out. It's the worst place in the canal for such a big ship to be stuck."
Meanwhile, shipping companies have reported more than 300 idled vessels on either side of the canal, which links the Mediterranean Sea with the Red Sea and is a crucial waterway for global trade and energy shipments. For days, as Egyptian authorities tried to clear the canal, shipowners and operators have debated whether to reroute -- adding weeks and tens of thousands of dollars to the cost of voyages -- or wait for the canal to free up again.
