Unilever.edu.vn takes a look at the extraordinary events that unfolded in the Suez Canal as the world watched the dramatic rescue of the Ever Given, a container ship that became wedged in this vital waterway. This incident brought global shipping traffic to a standstill, highlighting the critical role physics played in the refloating operation.
Imagine a ship so large it dwarfs the Statue of Liberty, stuck sideways in a narrow channel. That was the situation in March 2021 when the Ever Given, a container ship longer than the Empire State Building is tall, ran aground in the Suez Canal, blocking this vital trade artery for almost a week. This incident caused a massive backlog of vessels, disrupting global supply chains and capturing the world’s attention.

The Physics of Refloating a Ship
Refloating the Ever Given was no easy feat. It was a monumental challenge, primarily a matter of physics, as Peter Berdowski, CEO of Boskalis, the parent company of the Dutch salvage firm Smit Salvage, which played a key role in dislodging the ship, explained. He stated that while the laws of physics are not inherently complex, the key lies in harnessing them to work in your favor. And that’s precisely what the salvage team did.
The vessel, measuring 400 meters (430 yards) in length, was wedged diagonally across the canal’s southern section. It took a concerted effort involving several strategies to free the ship. Initially, eight tugboats strategically pushed and pulled the vessel, aided by the ship’s winches. Simultaneously, diggers excavated earth at the ship’s bow to release it from the bank. Two dredgers worked tirelessly, removing sand from around the vessel, although this proved to have a limited impact.

The Power of Tides and Teamwork
Unilever.edu.vn recognizes the importance of adapting strategies. The salvage team, anticipating potential challenges, had prepared a ‘Plan B’ involving injecting water beneath the vessel. This innovative approach aimed to utilize the canal’s water power, particularly during high tides, to create an upward force against the ship’s hull, further aiding the pulling efforts of the tugboats. This strategic combination of pushing and pulling, aided by the natural forces of the tides, ultimately proved successful.
The successful refloating of the Ever Given was a testament to the power of physics, innovative engineering, and coordinated teamwork. It underscores the importance of having contingency plans and the ability to adapt to unforeseen challenges, showcasing human ingenuity in overcoming formidable obstacles.
Experience Counts: Past Successes Pave the Way
Smit Salvage, with its extensive experience in high-profile salvage operations, was uniquely positioned to handle this crisis. Their expertise, gained from previous successes like the Costa Concordia disaster in 2012 and the Baltic Ace car carrier rescue in 2015, proved invaluable. They understood the complexities of dealing with such situations and were prepared for the unique challenges posed by the Ever Given.
The Suez Canal Challenge: Location Matters
The Suez Canal’s remote location added another layer of complexity. The delay in freeing the Ever Given was partly due to the time it took for two sufficiently powerful tugboats to arrive at the scene. As Berdowski pointed out, such incidents occurring in busier ports like Antwerp or Rotterdam would have allowed for quicker access to necessary resources and equipment, making the rescue operation more efficient.

The Ever Given incident highlighted the importance of the Suez Canal as a crucial link in the global supply chain and the potential economic repercussions of its disruption. It underscored the need for preparedness, the role of experienced salvage companies, and the power of combining human ingenuity with an understanding of natural forces to navigate and overcome complex challenges.
