Titan Sub Disaster Caused By Design Flaws And Company Failures, Damning Final Report Says

The damning last study into nan Titan submersible implosion has blamed a multitude of factors for nan 2023 disaster, including creation flaws and failures by nan institution that launched nan doomed expedition.

Five group were killed erstwhile nan sub made a deep-sea voyage to nan wreckage of nan Titanic; a British businessman, a French explorer, a begetter and son, and nan CEO of nan institution that operated nan dives.

In nan recently released 136-page investigation, nan Transportation Safety Board of Canada highlighted a bid of failures that led to nan underwater catastrophe.

OceanGate, nan institution down nan expedition, did not cognize “how agelong nan Titan’s unit hull would stay structurally intact erstwhile utilized many times for dives to nan extent of nan Titanic” nan study said.

​The Washington state-based institution built a brace of 1/3 standard models of nan Titan to trial really it responded to pressure, pinch six tests being carried retired connected nan models. However, some grounded astatine depths supra nan resting spot of nan Titanic, investigators found. ​

Inspectors noted successful nan study that normal engineering practices would expose full-scale models to “hundreds, perchance thousands,” of trial cycles. ​

While tests balanced to nan Titanic’s extent and deeper were carried out, location was nary further study to understand if nan hull could neglect aft repeated use, they said. ​

The Titan’s c fibre cylinder was accumulating harm each clip it was exposed to utmost pressures connected deep-ocean dives, nan study says. However, nan “as-built properties of nan Titan’s c fibre cylinder were ne'er validated to guarantee they met nan theoretical values utilized successful nan creation process.”

​Also, nan building and testing of nan Titan “did not travel modular engineering practices.”​

The study stated that location was “no precedent for diving a human-occupied c fibre submersible to nan heavy ocean,” pinch OceanGate acknowledging publically and internally that its operations progressive risk, nan study said.

However, “over nan people of OceanGate’s operating history, immoderate OceanGate labor pinch expertise successful circumstantial areas near nan institution aliases were dismissed aft raising safety-related concerns aliases expressing differing perspectives from nan CEO,” nan investigators said, listing aggregate examples.

The Canadian report’s conclusions echo those reached by nan U.S. Coast Guard Marine Board of Investigation and nan U.S. National Transportation Safety Board past year.

In its 2025 report, nan NTSB noted that nan c fibre composite unit alloy contained “multiple anomalies” and grounded to meet spot and durability requirements.

The study followed nan Coast Guard’s ain 2025 probe into nan incident, which besides blamed nan c fibre hull for nan implosion but besides branded information procedures astatine OceanGate arsenic “critically flawed.”

Canadian officials noted that nan alloy whitethorn person sustained harm connected a number of occasions, including erstwhile it collided pinch nan larboard front of nan Titanic successful 2022. Almost 2 weeks later, a large bang was heard erstwhile nan Titan surfaced from different dive, according to each 3 reports.​

The alloy was besides near extracurricular and exposed to nan elements from July 2022 until February 2023, Canadian officials and nan U.S. Coast Guard noted.

TSB Chair Yoan Marier said successful a property release that nan statement has been calling for “stronger regulatory surveillance successful nan marine assemblage for years.”

​“When it came to nan Titan, captious accusation existed crossed aggregate national governmental organizations, but nary 1 was responsible for connecting nan dots,” Marier said.

“Without a complete image of nan operation, nan Titan continued to run successful Canada without regulatory oversight.”​

The Titan expedition launched from St John’s, Newfoundland, successful Canada. ​British businessman Hamish Harding and French Explorer Paul-Henri Nargeolet were among nan 5 group killed successful nan implosion, on pinch Pakistani businessman Shahzada Dawood and his 19-year-old son, Suleman. ​

The father and son’s remains were returned arsenic “slush” successful “two mini boxes,” Suleman’s mother Christine Dawood later told The Guardian. ​

Stockton Rush, nan co-founder of OceanGate, was besides killed successful nan implosion. Had he survived, nan U.S. Coast Guard said successful its study that it would person contacted nan Justice Department for their consideration connected whether to prosecute manslaughter charges.

OceanGate’s different co-founder Guillermo Söhnlein told Sky News past twelvemonth that he cannot take sides Rush complete of nan issues relating to nan vessel’s hull.

According to Söhnlein, who near OceanGate successful 2013, Rush “did what he did, and he said what he said.”

However, Söhnlein added that while it could beryllium “easy” to spot Rush arsenic a “criminal”, for those who knew him anterior to nan disaster he was a “human being conscionable for illustration us.”

When asked if Rush had been “cavalier” pinch information and regulations, Söhnlein nodded.

The Independent has contacted Söhnlein for remark connected nan latest report.
