摘　　要：海上风电场海上段电量的送出是通过海底电缆来实现的,海缆敷设施工有埋设犁敷设和后冲埋敷设两种方式。相比常规的敷埋海缆施工,后冲埋施工工艺可节省作业时间,提高功效,单根海缆施工时间周期可缩短30%以上。海缆后冲埋施工主要包含施工船就位、海缆探测定位和冲吸泥施工等步骤,详细介绍了每个施工步骤的操作流程和注意事项,以确保海缆埋深达到设计要求。The power transmission from offshore wind farms relies on submarine cables,which can be installed using burial plow method or underwater remotely operating vehicle(ROV)flushing burial method.In comparison to conventional cable laying approaches,the ROV flushing burial method offers time-saving and efficiency improvements,resulting in a reduction of over 30%in the construction period for each cable.The construction of the ROV flushing burial method of the submarine cable mainly includes the steps of construction ship positioning,submarine cable detection and positioning,and mud flushing and suction construction.The operation process and precautions of each construction step are introduced in detail to ensure that the buried depth of submarine cable meets thedesign requirements.
