SUEZ, Egypt -- Experts boarded the massive container ship Tuesday that had blocked Egypt's vital Suez Canal and disrupted global trade for nearly a week, seeking answers to a single question: What went wrong?
As convoys of ships again began traveling through the artery linking the Mediterranean and Red Seas, a canal service provider said more than 300 vessels carrying everything from crude oil to cattle were still waiting for their turn in a process that will take days. Egyptian government officials, insurers, shippers and others similarly waited for more details about what caused the skyscraper-size Ever Given to become wedged across the canal on March 23.
When blame gets assigned, it likely will lead to years of litigation to recoup the costs of repairing the ship, fixing the canal and reimbursing those who saw their cargo shipments disrupted. Since the vessel is owned by a Japanese company, operated by a Taiwanese shipper, flagged in Panama and now stuck in Egypt, matters quickly became an international morass.
"This ship is a multinational conglomeration," said Capt. John Konrad, the founder and chief executive officer of the shipping news website gcaptain.com.
Experts boarded the Ever Given as it idled Tuesday in Egypt's Great Bitter Lake, just north of the site where it previously blocked the canal. A senior canal pilot, speaking on condition of anonymity because he was not authorized to talk to journalists, told The Associated Press that experts were looking for signs of damage and trying to determine why the vessel ran aground.
There could be significant damage to the the ship, Konrad warned. Stuck for days across the canal, the ship's middle rose and fell with the tide, bending up and down under the tremendous weight of some 20,000 containers across its quarter-mile length. On Monday, when workers partially floated the ship, all that pressure moved forward to its bow.
"Structural integrity is No. 1. You know, there was a lot of strain on that ship as it was sagging in the waterway," Konrad said. "They have to check everything for cracks and particularly that rudder and the propeller in the back that's connected to the engine room."
"And then they have to go through all the mechanical equipment, make sure they test the engines, all the safety valves, all the equipment, and then determine that it's safe to sail either by itself or with a tug escort to the next port," he added.
The ship's owner, Shoei Kisen Kaisha Ltd., said Tuesday that it would be part of the investigation along with other parties, though it did not identify them by name. It also refused to discuss possible causes of the grounding, including the ship's speed and the high winds that buffeted it during a sandstorm, saying it could not comment on an ongoing investigation. Initial reports also suggested a "blackout" struck the vessel, something denied by the ship's technical manager.
The company added that any damage to the ship was believed to be mostly on its keel. It said it was not immediately known whether the vessel will be repaired on site in Egypt or elsewhere, or whether it will eventually head to its initial destination of Rotterdam. That is a decision to be made by its operator, rather than the ship owner, the company said.
The Ever Given was seen to be stationary in the canal lake from the town of Fayed on Tuesday, still stacked with containers, with a specialist tugboat nearby. Other vessels in transit navigated around it.
CLEARING TRAFFIC JAM
The grounding of the ship had halted billions of dollars a day in maritime commerce. Analysts expect it could take at least another 10 days to clear the backlog -- though Egypt's president said Tuesday that it would take three. The losses to shippers, as well as any physical damage to the vessel, probably will lead to lawsuits.
Shoei Kisen Kaisha is covered with some $3 billion in liability insurance through 13 protection and indemnity clubs. Those clubs are not-for-profit mutual insurers used by the vast majority of global shippers.
Egyptian President Abdel Fattah el-Sissi traveled Tuesday to the canalside city of Ismailia to praise those who freed the vessel.
"We want to confirm to all the world, that things are back to as they were," he said. He stood before a sign that said: "Welcome to the Suez Canal: Egypt's lifeline of peace, prosperity and development."
The Ever Given had crashed into a bank of a single-lane stretch of the canal about 4 miles north of the southern entrance, near the city of Suez. That forced some ships to take the alternative route around the Cape of Good Hope at Africa's southern tip -- a 3,100-mile detour that costs ships hundreds of thousands of dollars in fuel and other expenses.
The unprecedented shutdown, which raised fears of extended delays, goods shortages and rising costs for consumers, added to strain on the shipping industry already under pressure from the coronavirus pandemic.
