The sequences of ships capture the sound of the sub-implose of the Oceangate Titangate

Senior scientific journalist
The moment when the submersible titana of Oceangate was lost was revealed in images recorded on the support ship of the sub-Sous-Marin.
Titan implodged about 90 minutes in a descent to see the wreck of the Titanic in June 2023, killing the five people on board.
The passengers had paid Oceangate to see the ship, which is at 3,800 m.
On board, the CEO of Oceangate Stockton Rush, the British explorer Hamish Harding, the French veteran Paul Henri Nargeolet, the British-Pakistani businessman Shahzada Dawood and his 19-year-old son Suleman.
The BBC had unprecedented access to the US Coast Guard (USCG) investigation for a documentary, the implosion: the Titanic sub-revision.
The images were recently obtained by the USCG and shows Wendy Rush, the wife of Mr. Rush, hearing the sound of the implosion while looking at the support ship of the sub-Sous-Marin: “What was that blow?”
The video has been presented as proof at the USCG Marine Board of Investigation, which has spent the last two years examining the catastrophic failure of the Sous.
The documentary also reveals that the carbon fiber used to build the submersible began to separate a year before deadly diving.
Titan’s support ship was with the submarine while it was plunging into the Atlantic Ocean. The video shows Ms. Rush, who was Director of Oceangate with her husband, sitting in front of a computer that was used to send and receive Titan SMS.
When the submarine reaches a depth of about 3,300 m, a noise that looks like a door slap is heard. Ms. Rush is considered a break, then look up and ask other members of the Oceangate crew what was the noise.
In a few moments, she then received an SMS from the submarine saying that he had dropped two weights, which seems to have brought him to wrongly think that the dive was going as planned.
The USCG says that the noise was actually the sound of the implodent Titan. However, the SMS, which must have been sent just before the failure of the submarine, took more time to reach the ship than the sound of implosion.
The five people aboard the Titan are instantly died.

Before the deadly dive, warnings had been raised by deep sea experts and some former Oceangate employees on the design of Titan. One described it as An “abomination” and said that the disaster was “inevitable”.
Titan had never undergone an independent security assessment, known as certification, and a key concern was that its shell – the main body of the submarine where passengers were seated – was made of carbon fiber layers mixed with resin.
The USCG says it has now identified the moment when the shell has started to fail.
Carbon fiber is a very unusual material for a submersible in the deep sea because it is not reliable under pressure. A known problem is that the carbon fiber layers can separate, a process called a dilapidation.
The USCG believes that the carbon fiber layers of the shell began to separate during a dive at the Titanic, which took place a year before the disaster – the 80th dive that Titan had made.
The passengers on board said they had heard a big blow while the submarine turned to the surface. They said that at the time, Rush said that this noise was the basement of his frame.
But the USCG says that the data collected from sensors adapted to Titan show that Bang was caused by the dilapidation.
“Diagram to Dive 80 was the start of the end,” said Lieutenant-commander Katie Williams of the USCG.
“And all those who rose aboard the Titan after diving 80 risked their lives.”
Titan took passengers on three other dives in the summer of 2022 – two to the Titanic and one to a neighboring reef, before failing during his next deep dive, in June 2023.

The businessman Oisin Fanning was on Titan for the last two dives before the disaster.
“If you ask a simple question:” Do I go again knowing what I know now? “-The answer is no,” he told BBC News.
“Many people would not have disappeared. Very intelligent people who lost their lives, who, if they had all the facts, would not have made this trip.”
The explorer in the deep sea Victor Vescovo said that he had serious doubts about Titan and that he had told people that diving in the submarine was like playing Russian roulette.
“I myself warned people to get into this submersible. I specifically told them that it was just a matter of time before he fails catastrophically. I told Stockton Rush himself that I thought that.”
After the sub-implication, its mutilated wreckage was discovered dispersed on the seabed of the Atlantic.
The USCG has described the scrutive process through the debris recovered – and said that Mr. Rush's clothes had been found, as well as business cards and Titanic stickers.

Later this year, the American Coast Guard will publish a final report of the conclusions of its investigation, which aims to establish what has gone wrong and prevent a disaster like this from happening.
Addressing the BBC documentary team, Christine Dawood, who lost her husband Shahzada and her son Suleman in the disaster, said that it had changed him forever.
“I do not think that anyone is suffering from a loss and such trauma can be the same,” she said.
The undulations of the Oceangate disaster should continue for years – certain private proceedings have already been filed and criminal proceedings can follow.
Oceangate told the BBC: “We once again offer our deepest condolences to the families of those who died on June 18, 2023 and to all those affected by the tragic accident.
“Since the tragedy has occurred, Oceangate has definitively completed its operations and has concentrated its resources on cooperation fully with surveys. It would be inappropriate to respond more while we are waiting for agency reports.”
You can look at the implosion: the Titanic sub-revision at 9 p.m. Tuesday, May 27 on BBC Two. It will also be available on the BBC Iplayer.
