With the deep carry-out of marine activities,further study of marine resources,and the vigorous development of oceanographic observation technologies both at home and abroad in recent years,the improvement of safety,routinization and standardization of ocean investigations had also been gradually raised.The paper,taking Ocean No.1's practical experience as an example, analyzed the differences,characteristics and safety-elements of the Spot sampling category,Tow class and Vessel-mounted class operations to explore to establish a more secure process of ocean investigation and general rules of emergency response.It is believed that further exploration and refinement of the process should be taken under different conditions,based on the ship,sea envi-ronment,operation types,equipment features and staffing and other actual conditions.As to sup-port investigation operations in an orderly,fast,safe and reliable manner,it should develop effec-tive voyage operations should be developed to adapt the above requirements.%随着海洋活动的进一步开展、海洋资源的深入研究以及近年来国内外海底观测技术的大力发展,对深远海调查作业规范化、程序化及安全性的要求也逐步提高.文章以"大洋一号"船实践经验为例,分析定点取样类、拖曳类、走航探测类3类作业的区别、特点及安全要素,探索建立安全性更高的深远海调查作业流程及应急处置通则.文章认为应对不同条件下作业流程的制定进行进一步的探索和细化,应根据船舶、海区环境、作业类别、设备特点及人员配备等实际情况制定行之有效的适应本航次要求的作业流程,以支撑调查作业有序、快速、安全、可靠的开展.
