Diggers and dredgers struggle to free ship blocking Suez Canal

Diggers were working to remove parts of the canal's bank and expand dredging close to the ship's bow to a depth of 18 metres (19.7 yards), the Suez Canal Authority (SCA) said in a statement.

There was no mention of new attempts to release the ship with tugs, though canal officials and sources had said they were hoping to take advantage of high tides on Sunday and Monday to dislodge the vessel.

A specialist tug registered in the Netherlands arrived and would join efforts to refloat the ship on Sunday evening, the ship's technical manager Bernhard Schulte Shipmanagement (BSM) said.

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.

Any operation to lighten the ship's load would not start before Monday, an SCA source said, as salvage teams try to manoeuvre the ship free before high tides recede next week.

The 400-metre (430-yard) long Ever Given became jammed diagonally across a southern section of the canal in high winds early on Tuesday, halting shipping traffic on the shortest shipping route between Europe and Asia.

At least 369 vessels are waiting to transit the canal, Rabie said, including dozens of container ships, bulk carriers, oil tankers and liquefied natural gas (LNG) or liquefied petroleum gas (LPG) vessels.

Shippers affected by the blockage may be offered discounts, Rabie said, adding that he believed investigations would show the canal was not responsible for grounding the Ever Given, one of the world's biggest container ships.

Rescue workers from the SCA and a team from Dutch firm Smit Salvage have been weighing how much tugging power they can use on the ship without risking damage, and whether some cargo will need to be removed by crane in order to re-float it.

Experts have warned that such a process could be complex and lengthy. Rabie said he hoped it would not be necessary, but that Egypt would take up offers of international assistance if it did switch to that strategy.

A ballast tank at the bow of the ship has been damaged, and the vessel will have to be inspected once it is freed, two people familiar with the salvage operation said.

Suction pumps have been deployed to expel water from the tank, SCA sources said, and one of the sources said divers had been working to repair the hole.

SOIL EXPERTS

Dredging has so far shifted at least 27,000 cubic metres of sand and mud from around the ship, the SCA said earlier on Sunday.

However, two SCA sources told Reuters that a mass of rock had been found at the bow of the ship, complicating salvage efforts. That appeared to be confirmed by the focus late on Sunday on digging to remove the lining of the canal around the ship's front.

Soil experts are on site to advise on recovery efforts and a further dredger was expected to arrive by March 30, BSM said.

From the dredging done so far it was still unclear whether the ship was stuck on soft sand, compact sand or clay, which will determine how easily it may shift free, said one official involved in the salvage operation.

Two new and powerful tugs expected to be in use by Monday could provide a boost. "We believe that is what you are going to need in terms of horse power ... to have a decent attempt, a decent chance of trying to float her," the official said.

The latest efforts come after officials said some progress had been made on Friday and Saturday.

"The rudder was not moving and it is now moving, the propeller is working now, there was no water underneath the bow, and now there is water under it, and yesterday there was a 4-metre deviation in the bow and the stern," Rabie told Egyptian state TV.

About 15% of world shipping traffic transits the Suez Canal, which is a key source of foreign currency revenue for Egypt. The current stoppage is costing the canal $14-15 million daily.

Shipping rates for oil product tankers nearly 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.

If the blockage drags on, shippers may decide to reroute their cargoes around the Cape of Good Hope, adding about two weeks to journeys and extra fuel costs.

A note from A.P. Moeller Maersk seen by Reuters said it had so far redirected 15 vessels around the Cape after calculating that the journey would be equal to the current delay of sailing to Suez and queuing.
