海底电缆全寿命周期的环保考虑

Environmental Considerations for the Life Cycle of Subsea Cables

随着海上风电等新能源项目的快速增加,海底电缆的应用需求日益提升。由于海底电缆运行在海床以下,一旦产生环境污染将导致严重的后果。分析了海底电缆从设计、制造、施工到运行、退役的整个寿命周期环节以及其中可能存在的环保问题,包括海缆设计、选型、原材料采购、生产和制造工艺、敷设施工、运行和维护、回收等过程中的环境污染及生态破坏,最后提出了改善性建议。

With the rapid increase of new energy projects such as offshore wind power,the application requirements of subsea cables are increasing.Since the subsea cables run below the seabed,environmental pollution will cause seri ous consequences.This paper analyses the whole life cycle of subsea cable from design,manufacture,construction to operation and retirement,the possible existence of environmental problems,including environmental protection,eco logical damage in the process of subsea cable design,selection,raw material procurement,production,manufacturing processes,installation,operation,maintenance and recycling.Finally,some suggestions for environmental protection improvement are put forward.
