Titan submersible disaster: Coast Guard hearing begins to investigate deadly implosion
The Titan submersible, which tragically imploded during its deep-sea descent to the Titanic wreck site, killing all five passengers, is now the subject of a U.S. Coast Guard investigatory hearing. The vessel, which began its journey off Canada’s coast on June 18, 2023, was operated by OceanGate and carried its American CEO and pilot, a French mariner, two businessmen, and one of their sons, the youngest passenger at 19, who brought his Rubik’s Cube on the voyage with hopes of breaking a world record.
Investigative focus: What caused the Titan’s catastrophic failure?
The U.S. Coast Guard’s two-week Marine Board of Investigation hearing, which commenced on Monday in North Charleston, South Carolina, will explore multiple factors surrounding the cause of the disaster. According to officials, areas of inquiry include “pre-accident historical events, regulatory compliance, crewmember duties and qualifications, mechanical and structural systems, emergency response, and the submersible industry.”
Engineers and executives from OceanGate, the Washington state-based company that developed and operated the Titan, are among those expected to testify, including co-founder Guillermo Söhnlein.
Jason Neubauer, chairman of the Marine Board of Investigation, stated in a press conference that the hearing aims to issue safety recommendations to prevent such tragedies in the future. “No family will experience such a loss again,” Neubauer said. He also mentioned that any findings of negligence or misconduct could be referred to the Department of Justice for further action.
OceanGate under scrutiny for design choices
In the aftermath of the Titan’s implosion, OceanGate has faced intense criticism for decisions that may have contributed to the tragedy. Experts familiar with the submersible’s design have raised concerns over the use of experimental materials, such as carbon fiber, which may not have been adequately pressure-tested for extreme deep-sea conditions.
Furthermore, the Titan’s cylindrical shape—intended to accommodate more passengers—deviated from the more common spherical designs used for submersibles, which provide greater structural integrity under pressure.
OceanGate initially touted the Titan’s construction, claiming it was made of “titanium and filament wound carbon fiber” and could “withstand the enormous pressures of the deep ocean.” However, the company has since suspended all exploration and commercial operations following the disaster.
Disaster at depth: Titan’s final moments
The Titan submersible lost contact with its support vessel, the Polar Prince, roughly two hours into its descent towards the Titanic wreck, located nearly 13,000 feet below the ocean’s surface. While the trip was expected to last approximately two and a half hours, followed by four hours of touring the wreck, the Titan never resurfaced. A massive search ensued, and debris from the submersible was discovered four days later, confirming the worst: the passengers likely perished instantaneously due to a “catastrophic implosion” caused by the intense pressure at such depths.
Among the victims were OceanGate CEO Stockton Rush, 61; French explorer Paul-Henri Nargeolet, 77; British billionaire Hamish Harding, 58; and Pakistani businessman Shahzada Dawood, 48, and his 19-year-old son Suleman. Each passenger had paid $250,000 for the once-in-a-lifetime opportunity to visit the Titanic wreck site.
Warnings ignored: Past concerns about safety
Despite OceanGate’s claims about the Titan’s safety, some had previously raised red flags about the submersible’s design. In 2018, David Lochridge, a former OceanGate employee hired to conduct manned tests, was fired after warning that the Titan’s carbon fiber hull had not undergone proper testing to ensure it could withstand the extreme depths of the Titanic site. In a counterclaim lawsuit, Lochridge alleged he was dismissed for voicing concerns that the vessel posed a risk to passengers’ lives. He is expected to testify during the Coast Guard’s investigation.
Legal action: Ongoing lawsuits against OceanGate
OceanGate now faces legal challenges in the wake of the disaster. The estate of French explorer Paul-Henri Nargeolet has filed a $50 million wrongful death lawsuit against the company, citing “persistent carelessness, recklessness, and negligence” in the submersible’s construction. Former OceanGate engineering director Tony Nissen, named as a defendant in the suit, is also slated to testify during the hearing.
A complex investigation at extreme depths
The ongoing investigation has been one of the most complicated the Coast Guard has ever undertaken, according to Neubauer. The Titan’s implosion occurred at extreme ocean depths, making the recovery of evidence a daunting task.
Peter Girguis, a Harvard University professor and oceanographer at the Woods Hole Oceanographic Institution, emphasized that the inquiry must provide a candid assessment of what led to the disaster. He noted that while the Titan’s design was unorthodox, it is not representative of the broader submersible industry, which generally adheres to stringent safety standards.
The future of deep-sea exploration: A call for regulation?
As the Titan investigation progresses, some experts are questioning whether high-risk deep-sea expeditions, such as Titanic tours, should be more tightly regulated, particularly in international waters. “We need to support innovators who think outside of the box, but we also need to ensure that safety is paramount,” Girguis remarked. He cautioned that while innovation is vital, it must not come at the cost of human lives.
The hearing’s outcome could shape the future of deep-sea exploration, with a focus on balancing innovation with safety. As Neubauer and his team work to uncover the causes behind the Titan’s catastrophic failure, the world watches for answers that could prevent such tragedies from happening again.
