The Ever Given was expected to be stuck in the Suez Canal for 'weeks still', so how did crews manage to free it? - ABC News

Salvage teams have finally managed to free the Ever Given, a colossal container ship that was stranded for nearly a week in the Suez Canal.

The successful re-floating mission has ended a crisis that clogged one of the world's most vital trade routes for oil and grain and other trade linking Asia and Europe.

Just a few days ago, the Suez Canal Authority estimated it could take "weeks still" to free the 400-metre-long vessel. 

That was echoed by Peter Berdowski, the head of Dutch company Boskalis, which helped to free the ship.

"We can't exclude it might take weeks, depending on the situation," he said.

How did they manage to free the skyscraper-sized ship so fast?

On Monday local time, a flotilla of tugboats, helped by the tides, managed to wrench the bow of the Ever Given from the canal's sandy bank.

Fourteen tugboats pushed and pulled to budge the behemoth from the shore, and their work was buoyed by a high tide at dawn.

Specialised dredgers also dug out the stern and vacuumed sand and mud from beneath the bow. 

The operation was extremely delicate. While the Ever Given was stuck, the rising and falling tides put stress on the vessel, raising concerns it could crack.

Speaking at a news conference on Monday evening, Suez Canal Authority chief Lieutenant General Osama Rabei praised the efforts of the workers to re-float the ship, saying they "achieved a very difficult mission in record time," without damaging the vessel or its cargo.

In the village of Amer, which overlooks the canal, residents cheered as the vessel moved along. 

How long will it take to clear the traffic jam in the Suez?

Navigation in the canal resumed on Monday at 6:00pm local time, Lieutenant General Rabei said, adding that the first ships in the queue were moving carried livestock.

From the city of Suez, ships stacked with containers could be seen exiting the canal into the Red Sea.

Lieutenant General Rabei said at least 113 of more than 420 vessels that had waited for the Ever Given to be freed were expected to cross the canal by Tuesday morning.

"Within 12 hours, 113 ships will cross in different convoys, either from Port Said or from Suez," he said.

"This means that within three days or three-and-a-half days the delay will be compensated, and we will not sleep."

Where is the Ever Given now?

The Ever Given has moved to the Great Bitter Lake, a wide stretch of water halfway between the north and south ends of the canal where it can be inspected for damage, Evergreen Marine Corporation said.

The ship's location was confirmed on ship-tracking website Vessel Finder on Tuesday afternoon AEDT.

How much has this all cost?

Lieutenant General Rabei estimated the cost of losses due to delays ranged between $US12 to $15 million per day.

The crisis lasted nearly a week.

"The ship is now in the lakes for inspection after the accident because we cannot allow it to sail until we are completely sure of its safety," Lieutenant General Rabei said.

"And at the same time, the investigation will take place and the cost of compensation will be revealed."

The head of the Suez Canal Authority also said the accident had proved the importance of the canal to the world. 

"Since the time of the accident, oil prices rose … the number of ships waiting until now, 422 ships, and none of them thought of taking an alternative route despite the canal being stopped for six days," he said.

"If they saw an alternative, they would have used it. The Cape of Good Hope is 10,000 miles more, which means three weeks more in addition to the security risks in it."

How did the Ever Given become stuck in the first place?

While it's not entirely clear what caused the ship to become stranded, the Suez Canal Authority said it had run aground after losing visibility and the ability to steer due to high winds and a dust storm.

Evergreen Marine Corporation — the Taiwan-based shipping company that operates the vessel — also blamed strong winds.

Lieutenant General Rabei said on Saturday that the strong winds and weather were not the sole responsible factors, saying there "may have been technical or human errors".
