A canal official, who requested anonymity, said that the team on the ground had started technical checks, and were reassured that the ship's motor was working.
The Ever Given's stern, or rearmost part, which had been only four metres from the shore, has now been wrenched away to 102m, the SCA said.
The German radio, NDR, said that ongoing European discussions at the level of the European Union are demanding that EVER GIVEN ship should be prevented from passing through any port in Europe due to its repeated technical problems that affect global navigation and the failure of its captain to control it.
Lt. Gen. Osama Rabei, the head of the Suez Canal Authority, said workers continued "pulling maneuvers" to refloat the vessel early Monday.
The operation to free the rest of the ship will resume when the water level rises in the late morning, said the SCA in a statement.
They had focussed on efforts to remove sand around the ship, with 27,000 cubic metres cleared at a depth of 18 metres (59 feet), SCA spokesman George Safwat said Sunday. Another powerful tugboat, Carlo Magno, was racing to the scene to join the efforts.
Dave Hinton, the owner of a timber company in northwest England, said he had a consignment of French oak stuck on a ship.
The Ever Given, a 224,000-ton vessel nearly as long as the Empire State Building is tall, ran aground in the Egyptian canal on March 23. Over 19,000 ships passed through previous year, according to canal authorities. Goods made in China - furniture, clothes, supermarket basics - bound for Europe also must go through the canal, or else take the detour around Africa. The unprecedented shutdown could affect oil and gas shipments to Europe from the Middle East.
It has roughly 20,000 containers on board including electricals, furniture and livestock.
Meanwhile, hope rose on Sunday as the MarineTraffic and VesselFinder applications said two tugboats were on their way to the vital waterway to help the salvage operation, while experts pinned hope on a high tide to dislodge the vessel.
