The landing of the cargo ship Evergreen in the Suez Canal prompted a massive operation to try to free it.
Those working on the matter warn that it could take days or even weeks. Evergreen, the longest of four football fields, runs at the southern end of the canal, blocking traffic on one of the busiest river corridors. Country. The world.
How can they move what someone has given them?
Ever Given, the company that manages Bernhard Schultz Management (PSM) operations, says up to nine towers have been used to free the ship.
The cargo ship was 400 meters long and crossed the canal more than 200 meters wide.
Using cables or standing directly next to the ship, the towers tried to lift it from the sand bar on either side of the canal.
That PSM Failure Try to float the ship andYou Thursday morning They will try again soon.
Saul Mercogliano, a marine historian at Campbell University in the United States, says that since the cargo ship is firmly entangled in both banks, all efforts to move it around have been difficult.
Work was also begun to excavate the canal around the ship.
Boscalis, a Dutch excavation company, oversees this and clears the sand and mud from the ship’s surface.
Peter Bertowski, CEO of Boscalis, called the vessel “a heavy weight in the sand” and said it would require three operations: excavation, digging but removal of weight from cargo.
According to marine expert Sal Mercogliano, the Suez Canal is somehow being excavated.
“Large machines are placed next to water and basically They extract Mud In the fund, you can deposit later LandHe explained.
In 2015 the canal was widened.
Remove cargo and fuel
The next phase of efforts to reload the 200,000-ton ship is to remove fuel and cargo.
A ship the size of an Evergreen can carry up to 20,000 containers 20 feet (6.1 cubic meters).
However, there are risks in doing this because it can cause damage and even the risk of the boat being thrown out of balance.
It can also be a subtle and time consuming process.
“You have to bring big floating cranes, but now whatever you do you have to calculate the stability of the ship and you have to determine how it will affect the stability,” Mercogliano says.
“In the worst case, the ship breaks in half due to (uneven) distribution of weight,” he adds.
Also, give it a try Removing cargo containers with floating cranes can be tricky How high they are stacked on the boat.
Removing fuel from the ship’s tanks would be an easy step, but would not reduce the weight sufficiently.
