摘　　要：“Kea Trader”沉船位于南太平洋新喀里多尼亚附近的浅水礁盘海域。为适应该海域的特殊海况地形条件,研究采用多种海洋勘测技术进行沉船打捞。针对打捞前的勘测阶段、施工船礁盘座底姿态监测阶段和沉船正式打捞阶段不同的技术要求,通过多种关键打捞技术的应用,完成了“Kea Trader”沉船的打捞。实际应用证明座底姿态监测、组合惯性导航和三维声纳实时监测等海洋勘测技术的组合应用能够有效地解决浅水礁盘海域沉船座底打捞面临的技术难题,提高沉船打捞效率。The wreck"Kea Trader"was located in the shallow water reef area near New Caledonia in the South Pacific Ocean.In order to adapt to the special sea conditions and topographical conditions,a variety of marine survey technologies were used to salvage the wreck.In view of the different technical requirements of the pre-salvage marine survey stage,the attitude monitoring stage of the working ship sitting on the bottom in the reef and the formal wreck salvage stage,the salvage of the wreck"Kea Trader"was completed by the use of various key salvage techniques.The practical application proved that the combined application of marine survey technologies such as the attitude monitoring of sitting on the bottom,integrated inertial navigation and 3D sonar real-time monitoring can effectively solve the technical problems of wreck salvage sitting on the bottom in the shallow water reef area and improve the efficiency of wreck salvage.
