Dynamic submarine cable for floating offshore wind power platform

as the connection between floating turbine and static submarine cable

is the key equipment to achieve offshore wind energy resources development

longdistance transmission and renewable energy utilization. In this paper

the technical development status of the dynamic cable is comprehensively described in accordance with the development context of dynamic submarine cable system

and from such factors as structure comparison between“dry”and“wet”of dynamic submarine cable

development of water resistant tree insulation material

related technology of cable accessories

failure factor of dynamic submarine cable

test method as well as engineering application. In particular

Such hot issues as test method of water resistant tree insulation material of dynamic submarine cable with“wet”structure and the test standard of dynamic submarine cable system are analyzed. The problems needing to be solved in the development of dynamic submariner cable are proposed

which include studying the long-term aging mechanism of water resistant tree insulation material

developing water resistant tree insulating material for higher voltage

optimizing accessory structure and manufacturing process

exploring joint testing technology of whole dynamic cable system and improving relevant specification and standard of China National standard concerning the submarine cable. The study can provide a reference for the design of dynamic submarine cable

development of key material and improvement of equipment manufacturing process and test technology in China.
