WASHINGTON – The US National Transportation Safety Board (NTSB) on Wednesday concluded that flawed engineering and inadequate testing were key factors behind the catastrophic 2023 implosion of OceanGate’s Titan submersible during an expedition to the Titanic wreckage.
The NTSB report follows an earlier US Coast Guard investigation in August that detailed serious lapses in OceanGate’s safety practices and design flaws, calling the tragedy “entirely preventable.” “We found that OceanGate’s engineering process for the Titan was inadequate and resulted in the construction of a carbon fibre composite pressure vessel that contained multiple anomalies and failed to meet necessary strength and durability requirements,” the report stated.

The agency said OceanGate failed to adequately test the submersible, leaving the company unaware of the vessel’s true strength and durability — both of which were “likely much lower” than intended. “Additionally, OceanGate’s analysis of Titan’s real-time monitoring data was flawed,” the report added. “The company was unaware that the Titan was damaged and needed to be immediately removed from service following a previous dive.”
Among the five who perished in the implosion were OceanGate CEO Stockton Rush, British explorer Hamish Harding, French oceanographer Paul-Henri Nargeolet, and Pakistani-British businessman Shahzada Dawood with his teenage son Suleman. Seats aboard the ill-fated sub cost $250,000 per passenger.

The Titan lost contact with its support ship about 1 hour and 45 minutes into its June 18, 2023 descent. A massive international search followed, captivating global attention until debris was discovered several days later near the Titanic’s bow. Human remains were later recovered when the wreckage was raised.
OceanGate has since suspended all operations, and the family of Paul-Henri Nargeolet filed a $50 million lawsuit last year, accusing the company of gross negligence.
The Titanic wreck, lying 644 km off Newfoundland’s coast, remains a haunting symbol of human ambition and loss. The ship sank in 1912 after striking an iceberg on its maiden voyage from England to New York, killing over 1,500 of the 2,224 people on board.
