Overview of offshore wind power gangway development and key technologies

The application of offshore wind power gangways ensures the normal operation of offshore wind turbines and provides reliable support for optimizing the boarding process, improving the operation and maintenance efficiency, and reducing the cost of wind power projects. This paper provides an overview of the development history and technological progress of gangways, and analyzes the main equipment in this field and its performance at home and abroad, as well as discussing the key technologies of offshore wind turbine gangways in such aspects as motion sensing and data analysis, compensation control and execution, structural design and reliability, and composite material application. It is pointed out that the parallel platform is the mainstream offshore gangway actuator; wave compensation is the core of equipment performance and the source of competitiveness; and advanced wave compensation technology depends on the development of sensor technology, artificial intelligence technology and other multidisciplinary development. This paper makes a comprehensive analysis for researchers and practitioners in the field of offshore wind power gangways, providing valuable references for subsequent technology exploration.
