海事事故是不可預知的風險，除了影響港埠營運外，對海洋環境與相關人員 的生命財產均會造成極為重大的傷害。本研究整理台灣各商港港務局所提供93 年度至98 年之各港務局紀錄的海事事故類型資料，海事事故共計1524 件之多， 平均每年約發生254 件，如何從經驗中記取教訓，「海事事故調查機制」為海事 安全政策中不可或缺的一環。因此從海事事故調查源頭建立完善機制，才能使後 續相關研究發揮更大之效用，所以本研究以各國海事事故調查機制為基礎與台灣 進行比較分析，以體制而言，應成立專業且獨立的海事安全調查機構；以法制而 言，建議應儘速立法，避免成為海事安全死角。並建立暢通聯繫管道以及資訊交 流程序，建立國際合作模式。
