What Really Happened at the Suez Canal?

Summary by Krater

This video explores the engineering principles, hydrodynamics, and geotechnical phenomena behind the March 23, 2021 grounding of the container ship Ever Given in the Suez Canal, concluding that the canal's shallow waters and bank effect contributed to the grounding and subsequent multi-day blockage.

From the video

Answers: Why did the Ever Given get stuck in the Suez Canal and how did it get un-stuck?

• Suez Canal geography and expansion
• Ship squat and bank effect hydrodynamics
• Dilation in sandy soils
• Ever Given ship specifications and salvage operations

What it concludes

• The Suez Canal is a sea-level waterway with no locks, handling roughly 10 percent of the world's ocean trade.
• An expansion completed in 2016 doubled the canal's capacity by adding a second shipping lane and deepening and widening choke points.
• When a ship travels in a shallow channel, the displaced water must squeeze through small areas, increasing speed and lowering pressure, which creates suction and pulls the ship toward the bank in a phenomenon known as the bank effect.
• The Ever Given's bulbous bow became wedged into the sandy embankment on both sides due to dilation pressure of the sand under movement.
• It took six days of dredging sand, releasing ballast water, and raising the tide with help from the moon to dislodge the Ever Given and resume canal traffic.
