A Spanish expert has used public information about the implosion of the Titan, the submarine that took tourists to see the wreckage of the Titanic, to piece together what may have happened on June 28, the Sunday when the vehicle disappeared 105 minutes after beginning its descent. ., on the northeast coast of Canada.

According to José Luis Martín, an engineer who worked on a tourist submarine, published data indicates that at a depth of around 1,700 meters, an electrical failure affected the mechanisms that gave the Titan stability – a factor key for this type of vehicle.

Without the propulsion that kept it in the correct position, the submarine tilted in the direction the crew was facing and fell vertically, “like a stone”, into the ocean for 48 to 71 seconds. Under these circumstances, the pilot could not have operated the safety lever, which, according to the engineer, was not sufficient. The report was produced at the request of the Spanish magazine nius.

There was a 900 meter fall which subjected the vehicle to a sudden increase in pressure. “The hull suffered an instantaneous contraction which was not accompanied by the window material, which was of a different nature, and since there was no similarity of deformation, a micro-crack developed. produced that allowed water to enter at such pressure that it generated an instantaneous implosion,” Martín told the publication.

OceanGate, the company that created the submarine and led the expedition to view the wreckage of the ship that sank in 1912, was warned of the unreliability of its machinery, but disagreed with the critical. Being an innovation, justifies the company, the company would not meet the certification standards in force.

The company’s president, Stockton Rush, was aboard the vehicle which suffered a “catastrophic implosion”, according to the US Coast Guard, killing him and four other passengers. The other victims are British billionaire Hamish Harding, 58, managing director of Action Aviation, Pakistani businessman Shahzada Dawood, 48, vice chairman of conglomerate Engro, and his son Suleman Dawood, 19, and Frenchman Paul-Henri Nargeolet, 77, expert. diver on the Titanic.

The Titan submersible was driven by a controller similar to one in video games, and its interior was cramped and simple. Rush even told US broadcaster CBS that the vehicle doesn’t require a lot of skill to drive. The submersible had only one button, which changed from red to green when activated, and vice versa.

The disappearance triggered a rescue operation involving vehicles, equipment and personnel from different countries, causing repercussions in all major media vehicles around the world. The wreckage was found on June 22, four days after the disappearance.

The US Coast Guard has opened an investigation into the matter, as has Canada’s.
