Titan anniversary: TSB still doesn't know if submersible was subject to government oversight

One year after a manned submersible was ripped to shreds over the wreckage of the Titanic, Canadian investigators say they still don't know if the federalgovernment provided any oversight of the doomed mission.

The Marine Transportation Safety Boardreleased an update into its investigation Monday, aday before the anniversary of OceanGate's fataltrip to the Titanic in its Titan submersible.

While much has been discovered about the sub's design and its fatal flaws, little is known about who if anyone was responsible for ensuring the safety of the mission, given that it was leaving from Canadian waters.

Transport Canada has maintained over the past year that it did not have jurisdiction over the submersible.

The TSBappears to disagree.

"The investigation has also established that there are Canadian regulatory requirements regarding these operations, and there is an internal Transport Canada (TC) policy on passenger submersible craft dated June 2005," reads Monday's update.

"However, the investigation has been unable to confirm whether these submersibles have been subject to oversight by TC or other certifying bodies."

Titan imploded June 18, 2023, en route to the Titanic. All five passengers were killed, including OceanGate CEO Stockton Rush.

The sub was initially reported missing, launching an international search effort that spanned four days.

The Canadian TSB is working alongside its American counterpartson the investigation. On Friday, the U.S. Coast Guard's marine board of investigation saidwork was taking longer than expected due to the complicated nature of the situation.

There have been two salvage missions since the submersible implodedand extensive forensic work done to reconstruct the incident.

The U.S. Coast Guard hopes to hold public hearings before the end of 2024.

Canadian investigators say the Titan made seven dives inside Canadian waters, and three dives in Canada's economic exclusion zone.

It made 19 dives in international waters, including each of its missions to the Titanic.

For each of the dives, Titan left from a Canadian port and was towed or carried by a Canadian-flagged ship. Despite that, neither Titan nor its launch platform were registered withany Canadian agency.

The TSB says Titan wasn't the only submersible operating under such circumstances in Canada.

"Some are registered in Canada; some are registered outside of Canada; and some are not registered."

Former search and rescue co-ordinator Merv Wiseman has been outspoken on the issue, saying Transport Canada should have had jurisdiction over the expeditions.

"It happened in plain daylight in front of everyone's eyes," he told The Fifth Estate earlier this year.
