A Canadian group wrote a report about the Titan submarine. Five people died in June 2023.

一個加拿大團體撰寫了一份關於 Titan 潛水艇的報告。2023 年 6 月共有五人喪生。

The submarine used a new material called carbon fibre. This material is not normal for deep water. The company did not test the submarine enough. The walls of the submarine became weak over time.

該潛水艇使用了一種稱為碳纖維的新材料。這種材料並不適用於深海環境。公司對潛水艇的測試不足。潛水艇的壁面隨著時間變得脆弱。

The company leaders did not listen to safety experts. They fired people who said the submarine was dangerous. No government group checked the submarine to see if it was safe.

公司領導層不聽取安全專家的建議。他們解雇了那些指出潛水艇危險的人。沒有政府機構檢查潛水艇是否安全。

The submarine went very deep. The water pushed too hard on the weak walls. The submarine broke in less than six seconds.

潛水艇潛入極深處。水壓對脆弱的壁面造成過大壓力。潛水艇在不到六秒內就損毀了。

The submarine broke because of bad tests and bad leaders. The group now has six ideas to make submarines safer.

潛水艇是因為測試不足與領導層失職而損毀的。該團體目前提出了六項建議，以提升潛水艇的安全性。

The Transportation Safety Board of Canada (TSB) has published a detailed report explaining why the Titan submersible imploded in June 2023, leading to the deaths of five people.

加拿大運輸安全局 (TSB) 已發表一份詳細報告，解釋泰坦號潛水艇為何在 2023 年 6 月發生內爆，導致五人死亡。

The TSB's engineering analysis shows that the company ignored standard maritime engineering rules. Specifically, using a carbon fibre hull was a new approach that had never been proven safe for deep-ocean travel. Although OceanGate tested small-scale models, these models failed at depths much shallower than the actual target. Furthermore, because the full-sized vessel did not undergo repeated pressure testing, the company did not know how much the hull had weakened over time due to environmental stress and physical impacts. Consequently, this material fatigue caused the hull to collapse about 5.4 seconds after the last message was sent at a depth of over 3,000 metres.

TSB 的工程分析顯示，該公司無視了標準的海事工程規則。特別是使用碳纖維船殼是一種新方法，從未被證明在深海航行中是安全的。雖然 OceanGate 測試了小型模型，但這些模型在遠淺於實際目標的深度就失效了。此外，由於全尺寸船體未經過重複壓力測試，公司並不清楚船體隨時間因環境壓力與物理衝擊而弱化了多少。因此，這種材料疲勞導致船體在深度超過 3,000 公尺、發出最後訊息後約 5.4 秒便崩潰了。

In addition to mechanical problems, the report emphasizes a serious failure in how the company was managed. The TSB noted that 'groupthink' and a refusal to accept opposing views were common, asserting that employees who raised safety concerns were often dismissed. This closed culture was made worse by a lack of regulation; the vessel did not have certification from any official government body or recognized safety organization. The TSB also observed that poor communication between different Canadian government departments prevented effective oversight, which allowed the operator to take risks without external checks or mandatory insurance.

除了機械問題外，報告還強調了公司管理上的嚴重失敗。TSB 指出，「群體思維」和拒絕接受反對意見的情況很普遍，並稱提出安全疑慮的員工經常被無視。這種封閉文化因缺乏監管而惡化；該船隻沒有任何官方政府機構或認可安全組織的認證。TSB 還觀察到，加拿大政府不同部門之間的溝通不良阻礙了有效的監督，使得營運商能在沒有外部檢查或強制保險的情況下採取風險。

The investigation concludes that the disaster happened because of insufficient testing and a poor safety culture. As a result, the TSB has suggested six recommendations to improve government monitoring of such vessels.

調查結論認為，此次災難是因為測試不足以及安全文化糟糕而發生。因此，TSB 提出了六項建議，以改善政府對此類船隻的監控。

The Transportation Safety Board of Canada (TSB) has released a comprehensive report detailing the causes of the June 2023 Titan submersible disaster, which resulted in five fatalities.

加拿大交通安全委員會 (TSB) 已發佈一份詳細報告，詳述 2023 年 6 月導致五人死亡的 Titan 潛水艇災難原因。

The TSB's engineering analysis identifies a critical divergence from established maritime engineering protocols. The utilization of a carbon fibre pressure hull was characterized as a novel approach lacking historical precedent for deep-ocean human occupancy. While OceanGate conducted limited testing on 1/3 scale models, these prototypes failed at depths shallower than the target destination. Furthermore, the absence of extensive cycle testing on the full-scale vessel meant the cumulative degradation of the hull—exacerbated by environmental exposure and physical collisions—remained unquantified. This material fatigue culminated in a structural failure approximately 5.4 seconds after the final transmission at a depth exceeding 3,000 metres.

TSB 的工程分析指出，該設計與既有的海事工程協定有嚴重偏差。使用碳纖維壓力殼被視為一種新方法，在深海載人方面缺乏歷史先例。雖然 OceanGate 進行了 1/3 比例模型的有限測試，但這些原型在達到目標深度之前就已失效。此外，由於缺乏對全尺寸船體進行廣泛的循環測試，導致船體在環境暴露與物理碰撞下的累積損耗一直未能量化。這種材料疲勞最終導致在最後一次傳訊後約 5.4 秒，在超過 3,000 公尺的深度發生結構失效。

Beyond mechanical deficiencies, the report highlights a systemic failure in corporate governance. The TSB noted the prevalence of 'groupthink' and confirmation bias, asserting that internal dissent regarding safety was suppressed through the dismissal of expert personnel. This insular culture was compounded by a regulatory vacuum; the vessel operated without certification from any recognized classification society or government body. The TSB further observed that fragmented communication between Transport Canada and other federal departments precluded effective oversight, leaving the operator to manage risk without external validation or mandatory insurance.

除了機械缺陷外，報告還強調了公司治理的系統性失效。TSB 指出「群體思維」與確認偏誤十分普遍，並聲稱內部對安全問題的異議透過解僱專家人員而被壓制。這種封閉的文化因監管真空而更加嚴重；該潛水艇在沒有任何認可的驗船協會或政府部門認證的情況下運行。TSB 進一步觀察到，加拿大交通部與其他聯邦部門之間的溝通破碎，導致無法有效監管，使營運商在沒有外部驗證或強制保險的情況下自行管理風險。

The investigation concludes that the disaster was the result of inadequate testing and a deficient safety culture, prompting the TSB to issue six recommendations for enhanced regulatory surveillance.

調查結論認為，此次災難是由於測試不足與安全文化缺陷造成，因此 TSB 提出了六項建議以加強監管視察。
