The 400-metre Panama-flagged Ever Given ship has been stuck sideways in the Suez since Tuesday morning after it ran out of power, this has meant that more than 200 vessels have been tailing back from the Suez Canal.
A dredger is used as salvage crews work to free the MV Ever Given, four days after it blocked the Suez Canal.
"Last night, there were signs of success.to the point that we were very hopeful that the salvage will be completed last night", The SCA chief said, adding authority is prepared with several scenarios to refloat the mega ship that causes "a big crisis".
The move was expected to be successful with the full moon and high tides expected tonight, but "unfortunately, the level of the waves did not always help" the company wrote on its Twitter account. "It will determine the next step, which highly likely involves at least the partial offloading of the vessel". Then during the Six Day War, Egypt imposed a blockade to prevent Israeli ships using the canal until 1975. It also would require a crane and other equipment that have yet to arrive.
The pilot spoke to The Associated Press on condition of anonymity as he wasn't authorized to brief journalists.
"With the ships we'll have in place by then, the earth we've managed to dredge, and the high tide, let's hope that'll be enough to budge the ship at the start of next week", Peter Berdowski told a public television chat-show late Friday.
Asked when the vessel might be freed, he sounded an optimistic note.
Egypt's President Abdel Fattah al-Sisi has ordered preparations for the possible removal of some of the ship's 18,300 containers, SCA Chairman Osama Rabie told Egypt's Extra News. Cmdr. Rebecca Rebarich, a U.S. Naval Fifth Fleet spokeswoman, said nothing had changed since U.S. Central Command made an offer to help on Friday.
"They were hoping high tides today would lift up the ship, because obviously with 20,000 containers it's going to be pretty low in the water, but obviously that hasn't been enough".
The mission to refloat the massive container ship stuck in the Suez Canal in Egypt resumed on Saturday - and the Dutch firm tasked with moving the ship said it could be freed by Monday.
Shipping rates for oil product tankers almost doubled after the ship became stranded, and the blockage has disrupted global supply chains, threatening costly delays for companies already dealing with COVID-19 restrictions.
A prolonged closure could also push energy prices higher - nearly 2 million barrels of oil pass through the canal daily.
As of early Sunday, over 320 ships waited to travel through the Suez, either to the Mediterranean or the Red Sea, according to canal services firm Leth Agencies.
Dozens of others still listed their destination as the canal, though shippers increasingly appear to be avoiding the passage.
The United States has also said it was ready to send support, including a team of US Navy experts.
