(Bloomberg) — An elite team is set to tackle the monumental challenge of freeing the massive container vessel that’s blocking the Suez Canal, as a backlog of ships continued to build up for a third day in what is arguably the world’s most important waterway.Work to re-float the Ever Given and free up oceangoing carriers hauling almost $10 billion of oil and consumer goods was expected to begin early Thursday in Egypt. Tugs and diggers failed to budge the vessel on Wednesday, and dredgers are still trying to loosen the vessel before any attempt to pull it out, the ship’s manager said.Still, the best chance for returning shipping to normal may not come until Sunday or Monday, when the tide will reach a peak, according to Nick Sloane, the salvage master responsible for re-floating the Costa Concordia, the cruise ship that capsized on the coast of Italy in 2012. Sloane works as the senior salvage master for Fort Lauderdale, Florida-based Resolve Marine Group.It’s taxing to even grasp how big this ship is. About a quarter mile long (400 meters) and weighing in at 200,000 tons, its sheer size is overwhelming efforts to dig it out. A huge yellow excavator, itself about twice as tall as its driver, looked like child’s toy parked next to the ship’s bulking bow.The struggle to dislodge the ship is now falling to SMIT Salvage BV, a legendary Dutch firm whose employees parachute themselves from one ship wreckage to the next, saving vessels often during violent storms. Japan’s Nippon Salvage Co. has also been hired to assist in the re-floating, according to a person familiar with the matter.This ship is so heavy that the salvors may have to lighten it by removing things like the ballast water, which helps keep ships steady when they’re at sea. Fuel could also be unloaded.How to Dislodge a 200,000-Ton Ship From a Canal Wall“Dislodging a grounded ultra-large container ship in the Suez Canal will be challenging due to the confined nature of the canal’s shipping channel,” said Rockford Weitz, director of the Fletcher Maritime Studies Program at Tufts University. “This presents additional complications in comparison to a grounding on a reef or shoal.”The Suez Canal Authority hasn’t commented on the work or given any indication of when traffic could resume.About 12% of global trade goes through the canal, making it so strategic that world powers have fought over the waterway since it was completed in 1869. For now, all that traffic is backed up with the Ever Given aground in the southern part of the canal, creating another setback for global supply chains already strained by the e-commerce boom linked to the pandemic.“Every hour, more vessels — including container ships, oil tankers, RoRo vessels, and bulk carriers — are being backed up in the Mediterranean to the north and the Red Sea to the south,” said Jett McCandless, chief executive officer of supply-chain tracking company project44. “It’s another big blow to global trade in an already back-logged and battered supply chain year.”A rough estimate shows the blockage is costing about $400 million an hour, based on calculations from Lloyd’s List that suggest westbound traffic is worth around $5.1 billion a day and eastbound traffic approximately $4.5 billion. On Wednesday, 185 vessels were waiting to cross the canal, according to shipping data compiled by Bloomberg, while Lloyd’s estimates there’s 165.About 34 container vessels chartered by Maersk Corp. and other shipping lines are either stuck in the canal or en route, according to project44. Preliminary reports show 10 crude tankers carrying a total of 13 million barrels could be affected by the disruption, according to Vortexa Senior Freight Analyst Arthur Richier.The incident began on Tuesday when strong winds blasted through the region and kicked up sands along the banks of the 120-mile canal. The waterway is narrow — less than 675 feet wide (205 meters) in some places — and can be difficult to navigate when there’s poor visibility.But Ever Given stayed its course through the canal, on its way to Rotterdam from China. As gusts that reached as high as 46 miles an hour swept up dust around it, the crew lost control of ship and it careened sideways into a sandy embankment, blocking nearly the entirety of the channel. It’s still in the same position as when it ran aground, according to Inchcape.At the heart of all of this is the ship’s massive scale. Container vessels have nearly doubled in size in the past decade as global trade expanded, making the job of moving such ships much harder when they get stuck.Even while key routes — including the Suez Canal — have been widened and deepened over the years to accommodate the mega-sized vessels, the work to dig them out after they get stuck takes enormous power.The canal is among the most trafficked waterways in the world, used by tankers shipping crude from the Middle East to Europe and North America, as well as in the opposite direction.The blockage highlights a major risk faced by the shipping industry as more and more ships transit maritime choke points including the Suez, Panama Canal, the Strait of Hormuz and Malacca Strait. Such occurrences could become more common as ships get bigger and waterways get more congested.Oil companies are starting to prepare for the worst. On Wednesday, there was an uptick in interest from oil companies looking to book tankers with options to avoid the canal, according to a broker, and several bid for space on the pipelines that allow bypass of the waterway completely.For now, that’s a just-in-case move. Container ships will most likely have to wait it out, as the main alternative is the unattractive option of sailing around the southern tip of Africa. However, at least one shipment of liquefied natural gas from the U.S. has potentially diverted course toward the Cape of Good Hope and away from Suez, Wood Mackenzie analyst Lucas Schmitt said in a note on Thursday.The disruption comes at a time when oil prices are already volatile. Crude surged above $70 a barrel earlier this month on Saudi production cuts, only to slump to near $60 this week due to setbacks in Europe’s coronavirus vaccine program. Brent crude rose more than 5% on Wednesday.Ever Given’s crew are safe and accounted for, and there have been no reports of injuries or pollution, according to the ship’s manager, Bernhard Schulte Shipmanagement. The vessel is also carrying cargo for logistics company Orient Overseas Container Line Ltd., according to Mark Wong, a company spokesman.For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2021 Bloomberg L.P.
