Canadian safety officials have released a damning report into the catastrophic implosion of the Titan submersible, citing design flaws, groupthink, and confirmation bias at OceanGate as key factors. The 6.7-metre carbon fibre vessel imploded near the Titanic wreck in June 2023, killing all five passengers instantly.
The Transportation Safety Board of Canada found that OceanGate failed to adequately test the novel submersible. The company built two one-third scale models, both of which failed at depths above the Titanic's resting place. Despite this, the full-scale Titan underwent relatively few pressure cycles, leaving engineers unaware of how many dives the hull could withstand.
Investigators discovered structural defects in the carbon fibre hull, including 'ply waviness' that weakened the material. Each deep dive accumulated damage, and the 14th dive proved fatal. The failure occurred 5.397 seconds after a text message from the crew, at a depth exceeding 3,000 metres.
The report also noted that the submersible was exposed to the elements for nearly a year and had sustained previous damage, including a collision with the Titanic in 2022. OceanGate's culture discouraged proper risk assessment, contributing to the disaster.
