According to the US Coast Guard, the investigation into the submersible Titan will “take longer than originally planned”

The U.S. Coast Guard continues to investigate the factors that contributed to the Implosion of the submersible Titan during a descent to visit the wreck of the Titanic, Killing all five people on board.

Tuesday marks one year since the submarine Titan, owned and operated by OceanGate Expeditions, lost contact with the Canadian research vessel Polar Prince about an hour and 45 minutes into its voyage across the North Atlantic.

On Friday, the U.S. Coast Guard’s Marine Board of Investigation said in an update that its investigation was a “complex and ongoing process” that would take longer than initially expected.

“We are working closely with our domestic and international partners to ensure a comprehensive understanding of the incident,” CEO Jason Neubauer said in a statement.

The Marine Board of Investigation stated that several factors, including the need to commission two recovery missions to secure important information, led to necessary delays and extended the original 12-month timeframe for the investigation.

“We are grateful for the international and interagency cooperation that was critical to the recovery, preservation and forensic examination of evidence from a remote offshore region and extreme depth,” said Neubauer. “The MBI is committed to ensuring we fully understand the factors that led to this tragedy in order to prevent similar incidents in the future.”

After the submarine Titan lost contact with the Polar Prince, a large-scale international search and rescue operation was launched over several days, as there would have been limited oxygen on board the submarine if it had been trapped beneath the water’s surface.

However, on June 22, 2023, the Coast Guard announced that the submarine had suffered a “catastrophic loss of the pressure chamber” during its descent. It confirmed that the Titan’s wreckage was located approximately 900 nautical miles east of Cape Cod, Massachusetts.

Among those killed in the implosion were OceanGate CEO Stockton Rush, Pakistani businessman Shahzada Dawood, his 19-year-old son Suleman, billionaire adventurer Hamish Harding and French explorer Paul-Henri Nargeolet.

OceanGate all operations stopped In early July 2023, the company, which charged $250,000 per person for a trip aboard the Titan, had was warned of potential security problems for years.

In October, the Coast Guard announced recovered “further suspected human remains” and what are believed to be the last remains of Titan.
