A Transportation Safety Board of Canada investigation into the fatal implosion of the Titan submersible has concluded that the tragedy was the result of both engineering failures and a lack of regulatory oversight.
The report, released Tuesday, examines the June 18, 2023 implosion that killed all five people aboard the Titan while it was descending to the wreck of the Titanic.
The vessel was owned and operated by U.S.-based OceanGate, but its expeditions were launched from St. John’s, Newfoundland and Labrador, with support from the Canadian vessel Polar Prince.
Investigators found the Titan’s carbon fibre hull deteriorated over time, with damage accumulating during repeated deep-sea dives.
According to the report, OceanGate never fully tested the hull to confirm it met design specifications and did not follow standard engineering practices during construction.
The investigation also found the company failed to properly identify and mitigate key risks associated with the vessel’s operation.
Oversight gaps identified
Beyond the design flaws, the report highlights broader issues with oversight.
The Transportation Safety Board says Transport Canada was aware the Titan was operating from Canada with the support of a Canadian vessel, but the submersible itself received no regulatory oversight.
Investigators also found information about OceanGate’s activities existed across several federal departments, including Fisheries and Oceans Canada, Parks Canada, the Canada Border Services Agency and Global Affairs Canada, but that information was not shared in a way that gave regulators a complete picture of the operation.
The board says those gaps contributed to increased risk.
Recommendations issued
As a result of the investigation, the Transportation Safety Board is issuing six recommendations focused on improving regulatory oversight, strengthening safety management and establishing clearer technical standards for submersibles.
Board Chair Yoan Marier said critical information existed across multiple government organizations, but no one was responsible for connecting the dots.
The board says the recommendations are intended to address systemic safety issues identified both in Canada and internationally.
