WATCH: James Cameron told the BBC he “felt in his bones” what happened to the submarine
Hollywood film director James Cameron, who directed 1997’s Titanic, told the BBC that the team that made the submarine that exploded with five people killed were “cutting corners”.
OceanGate, the parent company of the Titan sub, “didn’t get certified because they knew it wasn’t going to work.”
“I was very suspicious of the technology they were using,” he said. “I wouldn’t have had that branch.”
Cameron has completed 33 underwater dives in the wreck of the Titanic.
The Titan is built from carbon fiber and titanium.
In 2012, Cameron used a different technology for the Deepsea Challenger submersible mission in the Pacific Ocean, which took him to 10,912 meters (35,800 feet), the deepest known ocean trench.
The wreck of the Titanic fell to 3,810 meters (12,500 ft).
Cameron said that when he learned that the submarine had lost its navigation and communications at the same time, he immediately suspected a disaster.
“I felt in my bones what happened. The submarine’s electronics failed, its communication system malfunctioned, its transceiver failed at the same time – the submarine was gone.”
On Monday, he said, when he heard the submarine had gone missing, “I immediately called some of my contacts in the deep submersible community.
Within about an hour I learned the following facts. They were descending. They were at 3,500 meters (11,483 ft), going to bottom at 3,800 metres.
“Their communications are lost, mobility is lost—and I said right away, you can’t lose communications and mobility all together without an extreme catastrophic event or a hyperactivity catastrophic event. And the first thing that came to our mind was implosion.”
On Thursday, a US Navy official told BBC partner CBS News that the Navy detected an “acoustic anomaly consistent with an implosion” shortly after Titan lost contact with the surface.
The official said the information was passed on to a US Coast Guard team, which used it to narrow the radius of the search area.
Cameron suggested that there was a “terrible irony” in the loss of the Titan and its crew, likening it to the loss of the Titanic itself in 1912.
“We now have another wreck that unfortunately builds on the same principles of not heeding warnings,” he said. “Oceangate has been warned.”
Some within the deep immersion community, not directly including himself, Cameron said, have written a letter to OceanGate saying they believe, in his words, “you’re on a path to disaster.”
A letter sent to OceanGate by the Marine Technology Society (MTS) in March 2018 and obtained by The New York Times stated that “the current ‘experimental’ approach adopted by OceanGate … can lead to negative results (from minor to catastrophic).”
Separately, US court documents show that a former OceanGate employee warned of potential safety issues with the vessel as far back as 2018.
Documents show that David Lockridge, the company’s director of marine operations, raised concerns in the inspection report.
But the co-founder of OceanGate insisted that the Titan had undergone rigorous testing.
Guillermo Sohnlein, who left the company 10 years ago, told the BBC the 14-year development program had been “very strong”.
“Any expert who thinks about this, including Mr. Cameron, will also admit that it was not there to design the submarine, engineer the submarine, build the submarine, and certainly not to the rigorous testing program that the sub went through.”
The Titan Sub is not certified, but this is not mandatory.
In a blog about it in 2019, the company said that the way the Titan was designed falls outside the accepted order — but that “doesn’t mean OceanGate doesn’t meet the standards that apply to it.”
She added that rating agencies have “slowed innovation…Having an outside entity keep up with every innovation before putting it to the real-world test is anathema to rapid innovation.”
Cameron told BBC News that the past week had “felt like a long, nightmarish charade with people walking around talking noise and talking about oxygen and all this other stuff”.
“I knew the submarine was sitting exactly below its last known depth and position. That’s exactly where they found it,” he continued.
He said anyone venturing to the wreck of the Titanic should be fully aware of the dangers, as it is “a very dangerous site”.
Agree to these risks, but don’t be in a situation where you haven’t been told about the risks of the actual platform you’re diving into.
“In the 21st century, there shouldn’t be any risks. We’ve managed to get through 60 years, from 1960 until today, 63 without deaths… So, you know, one of the saddest aspects of this is how preventable it really is.” .
