The tragedy of the Titan ship: The bizarre "round window" has just been salvaged, making the experts "scary"

The wreckage of the Titan submersible was transported to the US port by the US Coast Guard. American medical experts will also analyze the remains of the victims that were carefully recovered from the rubble at the site of the incident.

The anomaly from the Titan ship debris

Much of the wreck of the Titan submersible was recovered from the ocean after the severe explosion. Photos of large pieces of debris recovered and transported to shore in Canada have raised questions about why after such a catastrophic explosion, the ship was not broken, but still remained. very big break.

Among these was a piece of curved white metal, which appeared to be the outer shell of the Titan, up to 6m long. Another fragment shows cables, integrated computer systems and other mechanical components and a large domed fragment.

Experts previously told NBC News that the water pressure exerted on the vessel would be equivalent to the 10,000 tons of the Eiffel Tower.

It is said that the force of the explosion will be so strong that the carbon fiber hull will "crumble", vaporize and kill everyone inside before they know what's happening.

So why does the ship wreck seem to be intact?

Arun Bansil, a physics professor at Northeastern University, explains why we see such large debris.

"When a submersible is deep in the ocean, it's going to experience forces acting on the surface due to water pressure," he told Northeastern Global News.

"When this force is greater than the force that the hull can withstand, the ship will explode. It is important that the design of the hull protects the ship against the large external water pressure that is crushing the hull."

Professor Bansil says that most shipbuilding technology is based on steel, titanium and aluminum, with extreme pressure performance.

"However, the Titan hull has an experimental design made of another material. It uses mainly carbon fiber, which has the advantage of being lighter than titanium or steel. The properties of deep-sea carbon fiber are still poorly understood. . It can crack and break suddenly".

"Although it may seem counterintuitive, large objects do not usually break apart in an explosion," said Professor Bansil.

"For example, a pressure cooker often explodes with the top blown off but the fuselage intact. Titan's explosion will occur at its weakest points, such as defects in the hull. ship".

"When a crack breaks open, large pieces of the hull will no longer be subjected to the strong impact force, so they will more or less remain intact."

Recovering large debris will be very good for the investigation. Next time, the fragments will be put together to find out what caused the explosion.

The weird window

According to Peter Girguis, a professor and oceanographer at Harvard University, debris recovered from more than 3,000 meters below the ocean floor will be the key to explaining the fate of the passengers and which part of the ship was damaged.

"In a nutshell, investigators will look at the various pieces of debris they recover and try to determine where the error occurred," he told The Post.

Professor Girguis said the most likely culprit is still a carbon fiber hull or a combination of titanium and carbon.

Unlike most other deep-sea vehicles that use titanium or special steel, the Titan's hull is made of carbon fiber with a pair of titanium caps.

The Coast Guard said the debris was consistent with the conclusion of a catastrophic explosion, which caused Titan's pressurized hull to collapse on its own and break apart, killing the passengers.

Girguis also noted the Titan submarine's strange round glass window, which is different from the optimal design that has been proven and used on submersibles for decades in other countries.

"The window on the Titan is different from that design," he explains. "It's worth considering its role in this disaster."

And the sudden temperature change in the ice-cold deep sea "must be taken into account," adds Giguis. "Sudden temperature changes can cause additional stress and abnormal changes to the material."

In addition to the debris, the coast guard said all evidence - including presumed human remains - would be taken to a US port for analysis and testing. "The evidence will provide investigators in several international jurisdictions with important insights into the causes of this tragedy," Neubauer said.
