Due to the great height of suction jackets for offshore wind power foundations and poor sea conditions at the construction site, it is difficult for installation personnel to fix lifting hooks at great height and the risk is high for their safety. At present, there is no mature experience for reference, which brings great challenges to site construction. A set of intelligent sling and rigging system was innovatively developed for lifting and installation of suction jackets for Project C of Changle Offshore Wind Farm, which makes full use of information technology such as wireless communication, the Internet of Things to effectively solve the difficulty in positioning and aligning of the suction jacket and slings at high altitude and the safety of personnel working at heights, A total of 41 suction jackets were installed with the intelligent sling and rigging system, which proved to be technologically advanced with stable and reliable performance, and has great promotion value, conducive to promoting the technological progress of the offshore wind power industry.

Large diameter rock -socketed monopile construction of offshore wind power is difficult, risky and there is no practical experience for reference, which brings great test and challenge to the construction. In F Area of offshore wind farm project in Putian, Fujian, a pioneering drilling technology with dual casing was developed, it efficiency solved a serial of problems such as easy hole collapse, difficult casing recovery, and poor efficiency, etc. Through the operation of multiple machine positions, it is proved that the construction process is reasonable and feasible, which is conducive to the promotion and development of the industry.
