Race against time to find a submarine that has disappeared on its way to… Titanic wreck site She entered a new phase of despondency Thursday morning as the last hours of oxygen left aboard the tiny ship were likely ticking the clock.
Rescuers moved more ships and ships to the disappearance’s site, hoping that the underwater sounds they had detected for the second day in a row might help narrow their search for the urgent international mission. But the crew had only had a four-day supply of oxygen when the ship made contact Titanset off around 6 a.m. on Sunday.
Even those who expressed optimism warned that there were many hurdles: from locating the ship, to reaching it with rescue equipment, to bringing it to the surface — assuming it was still intact. And all of that has to happen before the passengers’ oxygen supply runs out.
The entire area being searched was twice the size of Connecticut in waters up to 13,200 feet (4,020 m) deep. Coast Guard District One Captain Jamie Frederick said authorities still hoped the five passengers on board would be rescued.
“This is a 100% search and rescue mission,” he said Wednesday.
The North Atlantic region where Titan disappeared Sunday is also prone to hazy and stormy conditions, said Donald Murphy, an oceanographer who served as chief scientist for the Sahel, making it a very challenging environment for a search-and-rescue mission. International Ice Patrol.
Meanwhile, the newly revealed allegations indicate that there were major caveats about ship safety during the submarine’s development.
Frederick said that while the sounds discovered provided an opportunity to narrow the search, their location and source had yet to be determined.
He said, “Honestly, we don’t know what they are.”
Retired Navy Capt. Carl Hartsfield, now director of the Woods Hole Oceanographic Systems Laboratory, said the sounds have been described as “disturbing noises,” but warned that research crews “have to put the whole picture together into context and they have to delete” potential man-made sources other than Titan. “.
The report was encouraging to some experts because submarine crews unable to communicate with the surface are taught how to strike a submarine’s hull to be detected by sonar.
The US Navy said in a statement on Wednesday that it was fielding a specialized rescue system capable of lifting “large, bulky, and heavy underwater objects such as aircraft or small ships.”
Titan weighs 20,000 lb (9,071 kg). The Navy said on its website that the US Navy’s Flyaway Deep Ocean Salvage system is designed to lift up to 60,000 pounds (27,216 kilograms).
Lost aboard the ship is the pilot Stockton Rush, CEO of the company leading the expedition. His passengers are a British adventurer, two members of a Pakistani business family, and an expert on the Titanic. OceanGate Expeditions oversaw the mission.
The 22-foot (6.7-meter) carbon fiber vessel was running late Sunday night, authorities reported, prompting a search in waters about 435 miles (700 kilometers) south of St. John’s.
Officials said the ship has a 96-hour supply of oxygen, giving them early Thursday morning to find and raise Titan.
The estimated oxygen supply is a useful “goal” for researchers, said Frank Owen, a submarine search and rescue expert, but based only on a “nominal amount of consumption”. The diver on board the submarine will likely advise passengers to “do anything to get your metabolism levels down so that you can really extend this,” Owen said.
At least 46 people have successfully traveled on the OceanGate submarine to the Titanic wreck site in 2021 and 2022, according to letters filed by the company with a US District Court in Norfolk, Virginia, which oversees matters related to the Titanic wreck.
One of the company’s first clients described a dive he took at the site two years ago as a “kamikaze operation.”
Imagine a metal pipe a few meters long with a sheet of metal for the floor. You can’t stand up. You can’t kneel. “Everyone sits close to or on top of each other,” said Arthur Lobel, a retired businessman and adventurer from Germany. “You can’t be claustrophobic.”
During the 2.5-hour descent and ascent, he said, the lights were turned off to conserve energy, with the only lighting coming from a fluorescent glow stick.
The dive was delayed again and again to fix an issue with the battery and counterweights. In total, the flight took 10.5 hours.
OceanGate has been criticized for using a simple commercially available video game console to direct the Titan. But the company said many of the ship’s parts are ready because they have been shown to be reliable.
“A 16-year-old is supposed to throw it,” Rush told CBC in an interview last year during his show by throwing the console around the cabin of the small Titan, and it is “very sturdy.” He said two spares were kept on the plane “just in case”.
The submarine has seven backup systems for returning to the surface, including sandbags, drop lead tubes and an inflatable balloon.
The temperature is just above freezing, and the bowl is too deep for scuba divers to reach, said Jeff Carson, professor emeritus of earth and environmental sciences at Syracuse University. He said the best chance of accessing the submarine might be with a remotely operating robot on a fiber-optic cable.
“I’m sure it’s horrible out there,” Carson said. “It’s like being in an ice cave and hypothermia is a real danger.”
Documents show that OceanGate was warned of potentially catastrophic safety problems due to 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 were inadequate and would put passengers at potentially severe risk on an experimental submarine.
The company insisted that Lochridge “was not an engineer and was not appointed or required to perform engineering services on Titan”. The company also says the ship in development was a prototype, not the now-lost Titan.
The Marine Technology Association, which describes itself as “a professional group of ocean engineers, technologists, policymakers and educators,” also expressed its concern that year in a letter to Rush, CEO of OceanGate. The association said it was crucial for the company to submit its prototype for tests supervised by an expert third party before launch in order to protect passengers. The New York Times first reported on those documents.
The lost passengers on Titan were British adventurer Hamish Harding. Pakistani nationals Shahzada Daoud and his son Suleiman, whose eponymous company invests across the country; and French explorer and Titanic expert Paul-Henri Nargolet.
Retired Navy Vice Admiral Robert Morett, now deputy director of the Institute for Security Policy and Law at Syracuse University, said the disappearance highlights the risks associated with deep-water work and recreational exploration of the sea and space.
“I think some people think that because modern technology is so good you can do things like that without incident, but that’s not the case,” he said.
