灾难性内爆，多名富豪深海丧生，事故原因公布

Core Viewpoint - The final investigation report by the U.S. Coast Guard on the Titan submersible implosion incident concludes that it was a "completely avoidable tragedy" due to severe operational failures by OceanGate, the company operating the submersible [1][5]. Group 1: Incident Background - The Titan submersible descended into the Atlantic Ocean on June 18, 2023, aiming for the Titanic wreck at a depth of 3,800 meters. It suffered a catastrophic implosion 90 minutes into the dive, just 500 meters from the wreck, resulting in the instant death of all five individuals onboard, including Stockton Rush, CEO of OceanGate, and three paying tourists [3][5]. Group 2: Investigation Findings - The 335-page report identifies significant issues in all aspects of OceanGate's operations, leading to the incident after years of continuous errors. The implosion was attributed to a loss of "structural integrity," with all individuals onboard experiencing a water pressure of 4,930 pounds per square inch, resulting in "instant death" [5][6]. - The primary cause of the accident was OceanGate's failure to adhere to established engineering safety and testing standards. The Titan was constructed from carbon fiber, a material not previously used for deep-sea submersibles, which is unreliable under high pressure due to its layered structure that can delaminate [5][6]. Group 3: Company Culture and Financial Issues - The report criticizes OceanGate for fostering a "toxic company culture" that discouraged employees from raising safety concerns and ignored obvious signs of potential accidents. Despite being aware of multiple safety issues, the company continued operations without proper inspections [6][7]. - Financial pressures led to delayed employee payments and decisions that compromised safety. A former employee indicated that the company's economic situation was dire, prompting dangerous choices [6][7]. Group 4: Regulatory Recommendations - The report suggests over ten safety recommendations for regulatory bodies, including the implementation of appropriate regulations for the commercial submersible industry, revocation of existing research vessel designations for submersibles, and requirements for operators to submit dive plans and emergency response plans before operations [7].
