China’s first deep-sea floating wind power platform, Haiyou Guanlan, generated over 22 million kilowatt-hours of electricity as of November 24, achieving its annual production target ahead of schedule.
The platform demonstrated excellent operational performance throughout the year, with 17 maintenance visits and a turbine availability rate of 99.94 percent. In March, despite strong winds and high waves in the Wenchang oilfield area and limited vessel resources, the team used modular transport for maintenance equipment, completing the major annual inspection in just three days.
Typhoons were the biggest challenge during summer. Before Typhoon Wipha in July, crews repaired protective film on three 100-meter blades 3.5 days ahead of schedule, eliminating safety risks and generating an additional 1 million kWh by leveraging stable wind conditions. In September, Haiyou Guanlan successfully withstood Typhoon Ragasa using its typhoon-resistance mode.
Operational capabilities also continued to improve. In late June, the platform installed a satellite communication and navigation system that ensured stable transmission of equipment and weather data even during severe typhoons, significantly enhancing onshore emergency decision-making. On October 12, an intelligent inspection system was commissioned, integrating rail-mounted robots and partial discharge detection to form a “multi-dimensional sensing + remote coordination” system. This upgrade reduces fault response time and boost power generation efficiency.
