Overview

• The NTSB said on Wednesday that a failed carbon‑fiber pressure vessel with multiple anomalies caused the 2023 Titan implosion.
• Investigators concluded OceanGate’s engineering process was inadequate and that the company did not properly test the submersible.
• The agency found OceanGate’s monitoring data analysis was erroneous, leaving the company unaware the Titan was damaged and should have been pulled from service after a prior dive.
• The findings track a Coast Guard investigation released in August that detailed widespread design and maintenance failures following 2024 public hearings.
• The implosion killed five people, including Paul‑Henri Nargeolet and OceanGate founder Stockton Rush, and the company has halted commercial trips as civil litigation proceeds, including a $50 million suit by Nargeolet’s family.
