The Transportation Safety Board of Canada said Saturday that it’s conducting an investigation into the loss of the Titan submersible and has been speaking with those who traveled on Titan’s mothership, the Polar Prince.
The development comes as authorities from the US and Canada began the process of probing the cause of the underwater implosion and grappled with questions of who was responsible for determining how the tragedy unfolded.
Maritime agencies are searching the area in the North Atlantic where the vessel was destroyed, killing all five people aboard. Debris was located about 12,500 feet (3,810 meters) underwater, several hundred feet away from the Titanic wreckage it was on its way to explore.
“We are conducting a safety investigation in Canada given that this was a Canadian-flagged vessel that departed a Canadian port and was involved in this occurrence, albeit in international waters,” said Kathy Fox, chair of the transportation board.
“Other agencies may choose to conduct investigations and that’s up to them.”
The Polar Prince left Newfoundland on June 16, towing the ill-fated Titan. There were 41 people on board — 17 crew members and 24 others — including the five who died when Titan imploded.
Fox said she understands the international interest and that the TSB will share information they collect with other agencies, like the U.S. National Transportation Safety Board and the U.S. Coast Guard, within the limits of Canadian law.
Voice recordings and witness statements are protected under Canadian law, she said.
“Our investigation will go where the evidence leads us,” she added. “We don’t want to duplicate efforts. We want to collaborate.”
The Royal Canadian Mounted Police also announced Saturday that they’ve initiated an examination of the circumstances that led to the Titan deaths to decide whether a full investigation is warranted. That full probe will only take place if it appears criminal, federal or provincial law may have been broken, officials said.
The Coast Guard led the initial search and rescue mission, a massive international effort that likely cost millions of dollars.
It was not entirely clear who would have the authority to lead what is sure to be a complex investigation involving several countries.
OceanGate Expeditions, the company that owned and operated the Titan, is based in the US but the submersible was registered in the Bahamas. OceanGate is based in Everett, Washington, but closed when the Titan was found.
Meanwhile, the Titan’s mother ship, the Polar Prince, was from Canada, and those killed were from England, Pakistan, France, and the US.
