“Titan” Sub Implosion Caused by ‘Inadequate’ Engineering, Says NTSB’s Final Report Into Disaster

The report by the National Transportation Safety Board (NTSB) into the implosion of the ‘Titan’ submersible has concluded that the tragedy was caused by ‘inadequate’ engineering. This incident took place in June 2023 and resulted in the loss of all five individuals on board. The NTSB investigation revealed that the faulty engineering of the submersible was a key factor in its implosion as it made its way towards the Titanic wreck. The agency highlighted that the construction of Titan’s carbon fiber composite pressure vessel had multiple anomalies and failed to meet necessary strength and durability requirements. OceanGate, the company behind Titan’s construction, was also criticized for not adequately testing the submersible, leading to a lack of awareness regarding its structural integrity.

According to the NTSB’s findings, the pressure vessel of the submersible sustained damage after its 80th dive but continued to operate until its catastrophic 88th dive. The vessel’s condition worsened between dives, with further damage occurring after the 82nd dive, ultimately culminating in a ‘bucking failure’ that caused the Titan to implode deep in the Atlantic Ocean. The individuals on board at the time of the implosion included OceanGate founder Richard Stockton Rush III, operating the sub, along with Paul-Henri Nargeolet, Shahzada Dawood, Suleman Dawood, and Hamish Harding. The NTSB report highlighted that Titan should have been taken out of service after the 80th dive, but flawed analysis of the pressure vessel data by OceanGate delayed the identification of the vessel’s damage.

The NTSB’s investigation also pointed out that adherence to emergency response protocols could have led to the earlier discovery of the submersible, potentially saving time and resources during the search operation. The report from the U.S. Coast Guard, released earlier in August, echoed the NTSB’s findings and deemed the tragedy preventable. The Coast Guard’s Marine Board of Investigation identified OceanGate’s inadequate design, certification, maintenance, and inspection processes as primary contributing factors to the disaster. The 300-page Report of Investigation delved into additional issues within OceanGate, such as a toxic workplace culture and ineffective safety protocols.

OceanGate, in response to the Coast Guard’s report, expressed condolences to the families affected and confirmed the cessation of its operations to cooperate fully with the ongoing investigations. The NTSB’s recommendations include the commissioning of a panel of experts by the Coast Guard to study submersibles and other pressure vehicles for human occupancy, with a view to enhancing industry safety regulations based on the study’s outcomes. The incident involving the Titan submersible, which went missing en route to the Titanic wreck in June 2023, evoked a global response during the search and recovery efforts. The debris of the 22-ft. sub was ultimately located near the Titanic wreck, bringing a tragic end to the operation.

The documentary ‘Titan: The OceanGate Disaster’ shed light on the decision-making processes that led to the sub’s implosion, emphasizing the role of OceanGate’s CEO in the tragedy. The documentary highlighted the need for adherence to safety regulations and engineering standards in all operations, irrespective of individual beliefs or perspectives. The ‘Titan’ sub incident serves as a poignant reminder of the importance of stringent safety measures and thorough inspection processes in high-risk environments, such as deep-sea exploration missions. The findings of both the NTSB and the U.S. Coast Guard underscore the critical need for robust safety protocols and a culture of accountability in maritime operations.
