Titanic submarine update: Details about design of sub may reveal how it imploded as presumed human remains found

Shahzada Dawood, 48, was vice chairman of one of Pakistan’s largest conglomerates, Engro Corporation, with investments in fertilizers, automotive, energy and digital technologies.

Mr. Dawood was on board titanium Carrying his 19-year-old son, Suleman Dawood, the submersible had collapsed when it imploded on Sunday June 18.

Mr. Dawood was interested in wildlife photography, gardening and exploring natural habitats.

Mr Dawood’s wife, Christine Dawood, said the expedition to Titanic meant the world to Shahzada and Suleman, who described them as true explorers bound by a love of adventure.

“These two best friends have embarked on this final journey, their final journey together.”

French diver Paul-Henri Nargeolet, 77, was head of underwater research at a company that owns the rights to the Titanic wreck and recovers artifacts.

A former commander of the French Navy, he was both a deep diver and minesweeper. After retiring from the Navy, he led the first Titanic salvage expedition in 1987 and several others, becoming a leading authority on the wreck.

OceanGate described Mr Nargeolet as “the greatest discoverer of Titanic”.

The former naval officer was born in Chamonix, France but spent his early years with his parents in Africa. He was married to American news anchor Michelle Marsh until her death in 2017.

He completed 35 dives in the submersible. In a 2020 interview, he spoke about the dangers of deep diving, saying, “I’m not afraid of dying, I think it will happen one day.”

The cost of the unprecedented search for the missing Titan submersible will easily run into the millions of dollars, experts said Friday.

“There is no other ocean search like it, especially since so many countries and even commercial companies have been involved in it recently,” said Norman Polmar, a Virginia-based naval historian, analyst and author.

The planes alone are expensive to operate, and the Pentagon puts the hourly cost in the tens of thousands of dollars. The search used P-3 Orion turboprop submarines and P-8 Poseidon and C-130 Hercules jet-powered submarines.

Some agencies may request a refund. But the US Coast Guard — whose bill alone will run into millions of dollars — is generally prohibited by federal law from collecting reimbursements for search or rescue services, said Stephen Koerting, a US attorney in Maine who specializes in maritime law .

“The Coast Guard has no intention, for legal or political reasons, to recover the costs associated with search and rescue from recipients of these services,” the Coast Guard said in a statement on Friday.

Several experts have said that the design of the titanium For deep dives, the submersible may not have been as suitable as other designs titanic Debris.

Chris Roman, a professor at the University of Rhode Island’s Graduate School of Oceanography, told the Associated Press that the elongated shape of the titanium could have increased the pressure from outside.

Mr Roman said the sphere was “the perfect shape” because the water pressure was the same on all sides.

The submarine imploded on Sunday June 18 with five people on board.

That implosion could have been caused by tiny cracks in the sub’s hull, according to Jasper Graham-Jones, associate professor of mechanical engineering and naval architecture at the University of Plymouth.

Each time the submarine went to the titanictiny cracks had formed.

“It might be small and unobtrusive at first, but soon it would become critical and result in rapid and uncontrollable growth,” Graham-Jones said.

Hamish Harding, 58, was a British billionaire, aviation tycoon and explorer.

Mr Harding is among five people killed in a failed submarine expedition.

“He was one of a kind and we loved him. He was a passionate explorer – no matter the terrain – who lived his life for his family, his business and for the next adventure,” read a statement from Mr Harding’s family.

In 2021, he made a record-breaking voyage to the Challenger Deep in the Mariana Trench, which is the deepest part of the ocean at 36,000 feet below sea level.

“What he accomplished in life was truly remarkable, and if we can take any small consolation from this tragedy, it is that we lost him in what he loved.”

Harding also made record-breaking trips to the South Pole alongside Apollo astronaut Buzz Aldrin, the oldest person to ever reach the pole, and Harding’s son Giles, 12, the youngest to ever accomplish the feat.

Pictures of the wreckage recovered from the submersible Titan at the bottom of the North Atlantic appear to confirm the theory that the ship suffered a massive implosion under pressure from the ocean.

Jonas Mureika, Professor of Physics at Loyola Marymount University, narrates The Independent that the description of the implosion as “catastrophic” refers to the intensity and speed of the event.

“The pressure at this depth (3.8 km) is incredibly high, about 400 times atmospheric pressure. That’s 6,000 pounds per square inch acting on the submarine – atmospheric pressure is about 15 pounds per square inch,” he noted in an email.

Gustav Kilander And Andrea Blanco Report:

Edward Cassano, CEO of Pelagic Research Services, held back tears as he described the moment the Titan submersible search and rescue “turned into a recovery.”

Just hours after arrival, Pelagic Research Services found debris from the imploded submarine and relayed the information to the victim’s families.

Mr Cassano spoke to the press at the end of the search when he said: “We have to apologize – there is a lot of emotion and people are tired.”

Pelagic Research Services’ remotely operated vehicle (ROV), Odysseus, was flown to the site titanic wreck to assist in the international search for signs of the five passengers or the titanium.

Odysseus is one of the few ROVs capable of reaching the depths where the titanic The wreck lies at 12,500 feet (3,700 meters). Until Odysseus was able to reach the seabed, the US Coast Guard and US Navy could not determine where the submarine was going or if it had imploded with certainty.
