A rescue operation was underway deep in the waters of the Atlantic Ocean on Monday in search of a technologically advanced submersible vessel carrying five people to document the wreckage of the Titanic, the iconic ocean liner that sank more than a century ago.
The vessel was reported overdue Sunday night about 435 miles south of St. John’s, Newfoundland, according to Canada’s Joint Rescue Coordination Centre in Halifax, Nova Scotia. Lt. Cmdr. Len Hickey said a Canadian Coast Guard vessel and military aircraft were assisting the search effort, which was being led by the U.S. Coast Guard in Boston.
Rear Adm. John Mauger, a commander for the U.S. Coast Guard, said additional resources would arrive in the coming days.
“It is a remote area — and it is a challenge to conduct a search in that remote area,” he said. “But we are deploying all available assets to make sure we can locate the craft and rescue the people on board.”
According to the Coast Guard, the craft submerged Sunday morning, and its support vessel lost contact with it about an hour and 45 minutes later.
The submersible was operated by OceanGate Expeditions.
David Concannon, an adviser to OceanGate, said the submersible had an 96-hour oxygen supply starting at roughly 6 a.m. Sunday. In an email to The Associated Press, Concannon said he was supposed to be on the dive but could not go due to another client matter. He said officials were working to get a remotely operated vehicle that can reach a depth of about 20,000 feet to the site as soon as possible.
OceanGate’s expeditions to the Titanic wreck site include archaeologists and marine biologists. The company also brings people who pay to come along, known as “mission specialists.” They take turns operating sonar equipment and performing other tasks in the five-person submersible. The Coast Guard said Monday that there was one pilot and four “mission specialists” aboard.
OceanGate said its focus was on those aboard and their families.
“We are deeply thankful for the extensive assistance we have received from several government agencies and deep sea companies in our efforts to reestablish contact with the submersible,” said a written statement from the company.
U.K. businessman Hamish Harding was one of the mission specialists, according to Action Aviation, a company for which Harding serves as chairman. The company’s managing director, Mark Butler, told the AP that the crew set out on Friday.
“There is still plenty of time to facilitate a rescue mission, there is equipment on board for survival in this event,” Butler said. “We’re all hoping and praying he comes back safe and sound.”
Harding is an adventurer who holds three Guinness World Records, including longest duration at full ocean depth by a crewed vessel. In March 2021, he and ocean explorer Victor Vescovo dived to the lowest depth of the Mariana Trench. In June 2022, he went into space on Blue Origin’s New Shepard rocket.
The expedition was OceanGate’s third annual voyage to chronicle the deterioration of Titanic, which struck an iceberg and sank in 1912, killing all but about 700 of the roughly 2,200 passengers and crew. Since the wreckage’s discovery in 1985, it has been slowly succumbing to metal-eating bacteria. Some have predicted the ship could vanish in a matter of decades as holes yawn in the hull and sections disintegrate.
The initial group of tourists in 2021 paid $100,000 to $150,000 apiece to go on the trip.
Unlike submarines that leave and return to port under their own power, submersibles require a ship to launch and recover them. OceanGate hired the Canadian vessel Polar Prince, a medium duty icebreaker that was formerly operated by the Canadian Coast Guard, to ferry dozens of people and the submersible craft to the North Atlantic wreck site. The submersible would make multiple dives in one expedition.
The expedition was scheduled to depart from St. John’s, Newfoundland, in early May and finish up at the end of June, according to documents filed by the company in April with a U.S. District Court in Virginia that oversees Titanic matters.
The submersible, named Titan, is capable of diving 4,000 meters or 13,120 feet “with a comfortable safety margin,” OceanGate said in its court filing.
Experts said Monday that rescuers face steep challenges.
Alistair Greig, a professor of marine engineering at University College London, said submersibles typically have a drop weight, which is “a mass they can release in the case of an emergency to bring them up to the surface using buoyancy.”
“If there was a power failure and/or communication failure, this might have happened, and the submersible would then be bobbing about on the surface waiting to be found,” Greig said.
Another scenario is a leak in the pressure hull, in which case the prognosis is not good, he said.
“If it has gone down to the seabed and can’t get back up under its own power, options are very limited,” Greig said. “While the submersible might still be intact, if it is beyond the continental shelf, there are very few vessels that can get that deep, and certainly not divers.”
Even if they could go that deep, he doubts they could attach to the hatch of OceanGate’s submersible.
Chris Parry, a retired navy rear admiral from the U.K., told Sky News the rescue was “a very difficult operation.”
“The actual nature of the seabed is very undulating. Titanic herself lies in a trench. There’s lots of debris around. So trying to differentiate with sonar in particular and trying to target the area you want to search in with another submersible is going to be very difficult indeed.”
