Design Scheme and Construction Technology of Batch Drilling Chain Anchor Group for Offshore Floating Wind Power System
With the advancement of wind power installation technology,offshore drilling technology and processes,offshore wind power systems are gradually extending to the fields of far seas and deep seas.When the water depth exceeds 50 m,or even 100 m,considering safety and economic factors,offshore wind power systems have gradually shifted from pile foundation support to chain anchoring.The existing pile foundations with large pore size embedded rock drilling and hammer piles can no longer achieve the purpose of floating wind power system anchoring.In order to meet the anchoring needs of floating wind power systems,this paper conducts a practical study on the chain anchor group technology using offshore batch drilling,and cementing techniques and processes,achieving chain anchoring of offshore floating wind power systems.
