Application of Comprehensive Surveying and Mapping in the Construction of Offshore Wind Power Cable Rear Protection
In order to improve the working efficiency and reduce the construction cost of the non-buried cable rear protection construction between offshore wind turbines,the multi-beam technology and side-scan sonar technology are comprehensively used to accurately map the topography and geomorphology of the non-buried cable rear protection construction area.According to the surveying and mapping results,combined with MS1000 imaging sonar and ship positioning and Ultra Short Base Line underwater positioning technology,concrete interlock row was laid on the hydraulic release frame for monitoring and positioning to carry out post-protection construction of the unburied cable.The construction technology improves the efficiency of interlocking concrete laying.Finally,the operation efficiency is improved and the construction cost is reduced,and good social and economic benefits are achieved.
