Faulty engineering led to implosion of submersible headed to Titanic – report

Faulty engineering led to the implosion of an experimental submersible that killed five people on the way to the wreck of the Titanic, the US National Transportation Safety Board (NTSB) has concluded in a report.

The NTSB made the statement in its final report on the hull failure and implosion of the Titan submersible in June 2023.

Everyone on board the submersible died instantly in the North Atlantic when Titan suffered a catastrophic implosion as it descended to the wreck.

British adventurer Hamish Harding and father and son Shahzada and Suleman Dawood died alongside OceanGate Expeditions’ chief executive Stockton Rush and Frenchman Paul-Henri Nargeolet.

Mr Dawood was a London-based businessman and adviser to the King’s charity Prince’s Trust International, with a focus on its work in Pakistan. His 19-year-old son was a student at the University of Strathclyde in Glasgow.

The NTSB report states that the faulty engineering of the Titan “resulted in the construction of a carbon fibre composite pressure vessel that contained multiple anomalies and failed to meet necessary strength and durability requirements”.

It also stated that OceanGate, the owner of the Titan, failed to adequately test the Titan and was unaware of its true durability.

The report also said the Titan likely would have been found sooner had OceanGate followed standard guidance for emergency response, and that would have saved “time and resources even though a rescue was not possible in this case”.

The NTSB report dovetails with a Coast Guard report released in August that described the Titan implosion as preventable.

The Coast Guard determined that safety procedures at OceanGate, a private company based in Washington state, were “critically flawed” and found “glaring disparities” between safety protocols and actual practices.

OceanGate suspended operations in July 2023 and wound down. Representatives for the company did not respond to a request for comment on Wednesday. A company spokesperson offered condolences to the families of those who died after the Coast Guard report was released in August.

The NTSB report recommends the Coast Guard commission a panel of experts to study submersibles and other pressure vehicles for human occupancy. It also recommends that the Coast Guard implement regulations for the vehicles that are informed by that study.

It also called on the Coast Guard to “disseminate findings of the study to the industry”, which has grown in recent years as privately financed exploration has grown.

The vessel had been making voyages to the Titanic site since 2021. Its final dive came on the morning of June 18 2023.

The submersible lost contact with its support vessel about two hours later and was reported overdue that afternoon. Ships, planes and equipment were rushed to the scene about 435 miles south of St John’s, Newfoundland.

A multi-day search for survivors off Canada made international headlines. It soon became clear there would be no survivors, and the Coast Guard and other authorities began lengthy investigations into what happened.
