Missing submersible near Titanic wreck has dwindling oxygen, official warns

“The search efforts have not yielded any results,” said Capt. Jamie Frederick, the Coast Guard’s response coordinator in the search. He added that U.S. and Canadian crews are working around-the-clock to support this complex search effort, pulling together a fleet of ships and aircraft to comb a search area about the size of Connecticut.

The vessel, called the Titan, was piloted by Stockton Rush, CEO of OceanGate, which operates the submersible, the company said. The four guests on the expedition were an English businessman, a retired French navy commander, a British-Pakistani businessman and his teenage son.

Choppy seas and rolling fog have complicated the search so far, said Chief Petty Officer Robert Simpson, a spokesperson for the Coast Guard’s First District, which is heading the effort. Another factor making it difficult is the distance to the search area itself, which is about 900 miles east of Boston.

Simpson and other defense officials have declined to say when the search-and-rescue effort will transition to a recovery operation, and whether the military would keep looking for the vessel past the point when they determine oxygen has run out.

It is also unclear what the plan is when and if the submersible is found.

“If the sub is located, then it’s up to the experts to tell us the next steps for salvaging and recovery,” Frederick said. “Right now, our effort is on searching.”

What is submersible tourism? The Titanic expedition, explained.

The Navy dispatched a system designed to haul up objects like planes and small vessels from the deep ocean floor, a spokesperson said. The Flyaway Deep Ocean Salvage System will arrive in Newfoundland on Tuesday evening, but it is unclear how long it will take to set up and arrive at the search area.

For it to be used, the crew would first need to find the vessel if it is resting on the sea floor. Few remotely operated vehicles can operate at such depths. One, the Curv-21, can work down to 20,000 feet underwater. Multiple systems worked in tandem to recover a helicopter off the coast of Japan in 2021 at a depth of more than 19,000 feet.

It is unclear if the Navy has dispatched a search vehicle like the Curv-21. One complication is getting it to the search area. It needs specialized ships to drop it into the water and recover it. The Navy has only a handful of those fleet ocean tugs, and in August it deactivated one such ship that operated in the Atlantic, the USNS Apache. It is also unclear if civilian ships with that capability have been mobilized.

Deep water, high pressure: Why the Titanic sub search is so complex

The search continued Tuesday after the Titan lost contact with its mother ship, the Canadian research vessel Polar Prince, during a dive on Sunday morning.

Coast Guard Rear Adm. John Mauger, who is leading the search by the Coast Guard and the Royal Canadian Air Force, said Tuesday that rescuers “have been working around-the-clock to bring all capabilities that we have to bear” to find the submersible and the people onboard.

The Titanic dive was organized by OceanGate Expeditions, a private research and tourism company that has conducted more than a dozen underwater expeditions since 2010. The company had completed Titanic dives in the past two years.

“We pray for the safe return of the crew and passengers,” Andrew Von Kerens and Jim Wilkinson, spokespeople for OceanGate, said in a statement to The Washington Post.

In addition to the pilot — identified by OceanGate as its CEO Rush — Mauger said those onboard included four “mission specialists” who paid to take part in the expedition.

Among them is Hamish Harding, a British businessman and seasoned adventurer, who posted on social media before the trip that he was on the vessel.

“This mission is likely to be the first and only manned mission to the Titanic in 2023,” he wrote on his social media before the dive.

Harding added that “a couple of legendary explorers” were onboard, including retired French navy commander Paul-Henri Nargeolet.

Nargeolet is the director of underwater research for E/M Group, a media and exhibition company whose affiliate, RMS Titanic, researches the Titanic and runs Titanic-focused exhibitions. His company did not immediately confirm whether Nargeolet was onboard the Titan.

What we know about the submersible missing near the Titanic wreck

British-Pakistani businessman Shahzada Dawood, 48, and his son, Suleman, 19, were also on the expedition, their family confirmed in a statement.

“[They] had embarked on a journey to visit the remnants of the Titanic in the Atlantic Ocean,” the family said. “As of now, contact has been lost with their submersible craft and there is limited information available.”

Ofer Ketter, a submersible pilot, told The Washington Post that one of his concerns is the passengers’ psychological well-being.

Ketter said that if he were piloting a submersible stuck at the bottom of the ocean, he would lower the flow of oxygen to a point that it’s safe but less than standard, assess battery power, and monitor carbon dioxide exhalation as well as temperature and humidity. But before all that, he would ensure that his passengers are remaining calm.

“You have to manage the mental system,” he said. “No one is trained to be in that condition.”

What it’s like inside the missing submersible: ‘As much room as a minivan’

OceanGate has explored the Titanic wreck and documented its rate of decay in trips over the past two years. CEO Stockton Rush told CBS News in 2022 that OceanGate’s eight-day expeditions cost $250,000 for every person who joins a dive to see the wreckage.

OceanGate alerted the Coast Guard of the Titan’s disappearance Sunday afternoon after contact was lost roughly an hour and 45 minutes into its dive. After the news of the vessel’s disappearance broke, OceanGate said in a statement that it was “mobilizing all options” to rescue those onboard and that its “entire focus is on the crew members in the submersible and their families.”

Finding the submersible that far underwater has been described by experts as a monumental task. The wreckage of the Titanic, which was touted as unsinkable before hitting an iceberg and sinking in April 1912, lies on the ocean floor under 12,500 feet of water, roughly 370 miles off the coast of Newfoundland. More than 1,500 passengers and crew perished in the disaster.

Canadian P-3 Aurora aircraft arrived on the scene to conduct sonar searches, while the Canadian research vessels Polar Prince and Deep Energy are continuing their surface searches, according to the Coast Guard. Mauger told ABC that the P-3 Aurora has been dropping sonar buoys and listening for any sign of the submersible.

“So, if they are making sound, that’s certainly one of the ways we’re going to use to locate them,” he said.
