The Transportation Safety Board of Canada (TSB) is set to release its final investigation report on Wednesday into the implosion of the Titan submersible, three years after the disaster claimed the lives of all five people on board.
The report is expected to be published online at around 1600 GMT and will include six recommendations, the authority said in advance.
The submersible went missing in June 2023 after setting out on an expedition to the wreck of the Titanic. The US Coast Guard, with the help primarily of Canadian forces, launched a large-scale search operation some 700 kilometres south of Newfoundland that was followed by people around the world.
Days after the vessel disappeared, a remotely operated underwater vehicle discovered the wreckage of the imploded submersible less than 500 metres from the Titanic.
Several other authorities have already investigated the incident and found serious failures on the part of the operating company OceanGate.
On board the Titan were OceanGate chief executive Stockton Rush, 61, French mariner Paul-Henri Nargeolet, 77, British adventurer Hamish Harding, 58, British-Pakistani business consultant Shahzada Dawood, 48, and his 19-year-old son Suleman.
