Oceanographer put forward a new version of the death of the 'Titan'

[Regnum] The reason for the explosion of the bathyscaphe "Titan" could be microcracks that appeared from water pressure during regular diving. This version of the death of a deep-sea submersible, which was heading for the wreckage of the sunken Titanic, was put forward by Jasper Graham-Jones, an associate professor at the University of Plymouth . This was reported by the British edition of The Independent .

“Every time the bathyscaphe went down to the Titanic, tiny cracks formed. They remain small and inconspicuous, but at a critical moment they increase rapidly and uncontrollably,” he said.

In addition, according to him, the elongated shape of the "Titan" could increase the external pressure. Graham-Jones noted that despite the strength and durability of the composites from which the body of the bathyscaphe was made, they also fail and do it in a slightly different way than other materials.

University of Rhode Island Graduate School of Oceanography Professor Chris Roman, in turn, noted that during each expedition, tiny cracks formed in the hull about 12 cm thick. At first they could be imperceptible and insignificant, but after a while they reached the limit - rapid and uncontrolled growth. He compared this process to repeatedly bending and unbending a wire, which leads to its breakage.

As IA Regnum reported, the bathyscaphe of the OceanGate Expedition company, designed to deliver tourists to the site of the sinking of the Titanic, disappeared on June 18 in the Atlantic Ocean. Communication with him was lost less than two hours after the dive. Five people were on board: OceanGate Expeditions founder (which owns the bathyscaphe) Stockton Rush, British billionaire Hamish Harding, Pakistani businessman and billionaire Shahzada Dawood and his 19-year-old son Suleiman, and French aquanaut Paul-Henri Narjolet.

Rush, according to Fox News, admitted on camera two years ago that he "broke some rules" while building the Titan submarine.

The wreckage of the Titan was found a few days later during searches at a depth of 3,800 meters. Professor of Florida International University Eileen Maria Marty noted that the destruction of the body of the apparatus occurred in just a fraction of a millisecond, so the passengers did not have time to feel the pain.

The historian of the submarine fleet, captain of the 1st rank, officer of the submarine fleet Nikolai Cherkashin, in an interview with IA Regnum, suggested that faulty batteries became the cause of the explosion on the Titan.

Former Royal Navy submarine captain Ryan Ramsey suggested that one of the possible causes of the disaster was the erroneously designed bathyscaphe hull.

New reason for the collapse of the bathyscaphe "Titan"

[Regnum] Chris Roman, professor at the Graduate School of Oceanography at the University of Rhode Island (USA), believes that microcracks in the body of the apparatus became the cause of the implosion (an explosion directed inward) on the Titan submersible. He told the Associated Press about it.

He recalled that the bathyscaphe had previously sank two dozen times to a depth, which led to microdamages in the hull 13 cm thick. In the end, the damage accumulated, the skin began to delaminate.

“This may be small and imperceptible at first, but it will soon become critical and lead to rapid and uncontrolled growth,” said the professor.

Roman also likened the process to repeatedly bending and unbending a wire, causing it to break.

As IA Regnum reported, the company OceanGate Expeditions, which organized the tragic immersion of the Titan to the Titanic, continued to invite guests on tours to the ship that sank in the Atlantic. The cost of one seat in the bathyscaphe is $250,000.

The Titan made its last dive on June 18, 2023. The vehicle included OceanGate Expeditions founder Stockton Rush , British billionaire Hamish Harding , French aquanaut Paul-Henri Narjolet, and Pakistani businessman Shahzada Dawood with 19-year-old son Suleiman.

Communication with the bathyscaphe was lost 1 hour 45 minutes after it went under water. A few days later, during the search, the wreckage of the Titan was found at the bottom at a depth of 3,800 meters. On June 29, the US Coast Guard announced that the wreckage of the apparatus had been lifted from the depths.

According to experts, the bathyscaphe exploded instantly, the passengers did not have time to feel the pain. The historian of the submarine fleet, captain of the 1st rank, officer of the submarine fleet Nikolai Cherkashin, in an interview with IA Regnum, suggested that faulty batteries became the cause of the explosion on the Titan.

#1 Experience w/composites for aircraft echoes same thing; microcracks that grow undetected until catastrophic failure.
Unlike aluminum, ‘ramp rash’from contact w/ GSE at the airports is not easily verified. That is one reason ndt for aircraft stuctures is so extensive. Unfortunately there was none of that cautious philosophy in play here.

#4 Of course Ocean Gate design philosophy was more like this, they probably didn't do anything to avoid bubbles in the fabrication because of difference in opinion .
