我國業已於2019年8月成立國家運輸安全調查委員會，符合國際主流之海事調查雙軌制度。海事調查之良莠，關鍵在執行業務之調查者。他們的知識、能力與經驗，除後天訓練外，在成為調查員前，任用制度是否完善至關重要。但航港局海事行政調查員，因受限公務人員任用制度，現今可期望新成立之運安會，能屏除航港局用人之困境，達成以海事安全調查補強行政調查不足，及達成防止類案再發生之目標。本文用文獻回顧法、列舉國際標準、比較與分析他國調查官任用及培訓制度等方式，對我國海事安全調查人才現況問題進行探討，針對運安會海事安全調查官之任用、培訓、晉升方面，提出三三三任用與培育策略、分級培育指標及其他建議，為我國整體海事調查事務之未來做出貢獻。

Taiwan recently established the Taiwan Transportation Safety Board (TTSB) in August, 2019. In maritime investigation, having an investigator who executes his duties well during good and bad times is essential. In addition to relying on acquired training for their knowledge, ability, and experience, it is crucial that the recruitment system be perfected prior to the appointing of investigators. However, the Maritime and Port Bureau's (MPB) original marine administrative investigator did not meet the required qualifications. At present, the TTSB should be able to eliminate the difficulties of MPB employment. With this, they can achieve the goal of supplementing administrative investigations with maritime safety investigations. Additionally, they can also prevent the recurrence of similar cases. This article uses literature reviews, list international standards, a compare and analyze the methods of recruitment and training systems of safety investigators in other countries. Moreover, it proposes a 333 construction plan and other substantive suggestions for the training, appointment, and promotion of TTSB's marine safety investigation officers. Furthermore, it contributes to the future of Taiwan's overall marine investigation affairs.
