US Coast Guard Bringing in More Ships, Vessels to Search for Lost Titanic Tourist Submersible

Rescuers on Wednesday rushed more ships and vessels to the area where a submersible disappeared on its way to the Titanic wreckage site, hoping underwater sounds they detected for a second straight day might help narrow their search in an increasingly urgent mission.

The full scope of the search was twice the size of Connecticut in waters 2½ miles deep, said Captain Jamie Frederick of the First Coast Guard District, who noted that authorities are still holding out hope of saving the five passengers onboard the Titan.

"This is a search-and-rescue mission, 100%," he said. " ... We'll continue to put every available asset that we have in an effort to find the Titan and the crew members."

But even those who expressed optimism warned that many obstacles remain: from pinpointing the vessel's location, to reaching it with rescue equipment, to bringing it to the surface — assuming it's still intact. And all that has to happen before the passengers' oxygen supply runs out, which some have estimated might happen as early as Thursday morning.

The area of the North Atlantic where the Titan went missing on Sunday is prone to fog and stormy conditions, making it an extremely challenging environment to conduct a search-and-rescue mission, said Donald Murphy, an oceanographer who served as chief scientist of the Coast Guard's International Ice Patrol. The lost submersible could be as deep as about 12,500 feet (3,800 meters) below the surface near the watery tomb of the Titanic.

Meanwhile, newly uncovered allegations suggest there had been significant warnings made about vessel safety during the submersible's development.

Frederick said while the sounds that have been detected offered a chance to narrow the search, their exact location and source hasn't yet been determined.

"We don't know what they are, to be frank," he said.

Retired Navy Captain Carl Hartsfield, now the director of the Woods Hole Oceanographic Systems Laboratory, said the sounds have been described as "banging noises," but he warned that search crews "have to put the whole picture together in context, and they have to eliminate potential man-made sources other than the Titan."

The report was encouraging to some experts because submarine crews unable to communicate with the surface are taught to bang on their submersible's hull to be detected by sonar.

The U.S. Navy said in a statement Wednesday that it is sending a specialized salvage system that's capable of hoisting "large, bulky and heavy undersea objects such as aircraft or small vessels."

The Titan weighs 20,000 pounds (9,071 kilograms). The U.S. Navy's Flyaway Deep Ocean Salvage System is designed to lift up to 60,000 pounds (27,216 kilograms), the Navy said on its website.

Aboard the vessel are pilot Stockton Rush, the CEO of the company leading the expedition. His passengers are a British adventurer, two members of a Pakistani business family and a Titanic expert.

Authorities reported the 22-foot carbon-fiber vessel overdue Sunday night, setting off the search in waters about 435 miles (700 kilometers) south of St. John's.

The submersible had a four-day oxygen supply when it put to sea around 6 a.m. Sunday, according to David Concannon, an adviser to OceanGate Expeditions, which oversaw the mission.

Frank Owen, a submarine search-and-rescue expert, said the estimated 96-hour oxygen supply is a useful "target" for searchers, but is only based on a "nominal amount of consumption." Owen said the diver on board the Titan would likely be advising passengers to "do anything to reduce your metabolic levels so that you can actually extend this."

At least 46 people successfully traveled on OceanGate's submersible to the Titanic wreck site in 2021 and 2022, according to letters the company filed with a U.S. District Court in Norfolk, Virginia, that oversees matters involving the Titanic shipwreck.

The submersible had seven backup systems to return to the surface, including sandbags and lead pipes that drop off and an inflatable balloon.

Jeff Karson, a professor emeritus of earth and environmental sciences at Syracuse University, said the temperature is just above freezing, and the vessel is too deep for human divers to get to it. The best chance to reach the submersible could be to use a remotely operated robot on a fiber optic cable, he said.

"I am sure it is horrible down there," Karson said. "It is like being in a snow cave and hypothermia is a real danger."

Documents show that OceanGate had been warned there might be catastrophic safety problems posed by the way the experimental vessel was developed.

David Lochridge, OceanGate's director of marine operations, said in a 2018 lawsuit that the company's testing and certification was insufficient and would "subject passengers to potential extreme danger in an experimental submersible."

The company insisted that Lochridge was "not an engineer and was not hired or asked to perform engineering services on the Titan." The firm also says the vessel under development was a prototype, not the now-missing Titan.

The Marine Technology Society, which describes itself as "a professional group of ocean engineers, technologists, policy-makers, and educators," also expressed concern that year in a letter to Rush, OceanGate's chief executive. The society said it was critical that the company submit its prototype to tests overseen by an expert third party before launching in order to safeguard passengers. The New York Times first reported on those documents.

Retired Navy Vice Admiral Robert Murrett, who is now deputy director of the Institute for Security Policy and Law at Syracuse University, said the disappearance of the submersible underscores the dangers associated with operating in deep water and the recreational exploration of the sea and space, "two environments where in recent past, we've seen people operate in hazardous, potentially lethal environments," Murrett said.

"I think some people believe that because modern technology is so good, that you can do things like this and not have accidents. But that's just not the case," he said.
