A final report into the Titan submersible implosion has identified multiple critical failures, including design flaws and shortcomings by OceanGate, the company behind the expedition. The disaster, which occurred in June 2023, killed all five people on board during a dive to the Titanic wreckage.
The 136-page investigation by the Transportation Safety Board of Canada found that OceanGate did not know how long the Titan's pressure hull would remain intact under repeated deep-sea dives. Tests on one-third scale models failed at depths above the Titanic, and full-scale models were not subjected to the hundreds or thousands of test cycles typical in engineering practice.
The report noted that the carbon fibre cylinder accumulated damage with each dive, but its properties were never validated against design specifications. Construction and testing did not follow standard engineering practices, and some employees who raised safety concerns were dismissed or left the company.
Canadian officials highlighted a lack of regulatory oversight, as the Titan operated from St John's, Newfoundland, without complete governmental awareness. The report echoed findings from the U.S. Coast Guard and National Transportation Safety Board, which also cited the carbon fibre hull and flawed safety procedures as key factors.
The victims included British businessman Hamish Harding, French explorer Paul-Henri Nargeolet, Pakistani businessman Shahzada Dawood and his son Suleman, and OceanGate CEO Stockton Rush. The U.S. Coast Guard noted it would have considered manslaughter charges had Rush survived.
