With the promotion of carbon peak and carbon neutrality strategy, offshore wind power is developing towards deep waters, facing server challenges of strong winds and waves. Traditional personnel transportation methods have significant safety hazards in harsh sea conditions, seriously restricting the high-quality development of project construction. It is therefore necessary to explore new methods for offshore resource support under complex sea conditions. Based on the fractal characteristics of waves, a fractal-wave compensation adaptive algorithm is proposed by combining with the active wave compensation and adaptive principles. An adaptive compensation trestle model is then established on the basis of this algorithm. The adaptive operation and maintenance ship is transformed through the installation of adaptive compensation trestles. Compared with the traditional operation and maintenance ship, the adaptive operation and maintenance ship transformed from an offshore wind power maintenance ship in the South China Sea can effectively solve the safety issues of personnel boarding. At the same time, the utilization rate of the sea window is increased by 3.5 times, the efficiency of the transfer personnel is increased by 3.3 times, and the comprehensive economic benefit is increased by 10.3%. The adaptive operation and maintenance ships have significant advantages in operations under complex sea conditions. It can provide resource support for subsequent deep-sea offshore wind power projects.
