Recently, the second high-speed wind power operation and maintenance vessel “Offshore Oil 512,” invested and constructed by CNOOC Energy Technology & Services Limited (Clean Energy Company), arrived in the waters of Yangjiang, Guangdong, successfully completing its first wind turbine operation and maintenance mission. This marks a further enhancement of CNOOC’s integrated offshore wind power operation and maintenance capabilities.
As offshore wind power ventures into deeper and more distant waters, with farther offshore distances, deeper operational areas, and harsher climatic conditions, new challenges arise for the stable operation of offshore wind turbines. To ensure smooth operation and maximize power generation, the Clean Energy Company has focused on building integrated offshore wind power operation and maintenance service capabilities through the coordinated advancement of “equipment + platform + system.”
As CNOOC’s first batch of high-speed wind power operation and maintenance vessels, “Offshore Oil 511” and “Offshore Oil 512” are designed with a speed of up to 18 knots. They can overcome challenges such as poor accessibility and high safety risks in offshore operations, enabling rapid response for wind power maintenance and providing a safe and convenient commuting support platform for operation and maintenance personnel. These vessels feature a catamaran design, offering outstanding stability and load capacity, with the ability to safely dock against wind turbine piles in significant wave heights of up to 2.5 meters while minimizing impact on the piles—ensuring safe boarding conditions for personnel.
The Smart New Energy Management Platform, independently developed by CNOOC Energy Technology & Services, serves as a critical aid for offshore wind turbine operation and maintenance. For wind farms connected to this platform, operators can monitor turbine status in real time, promptly address alarms, and utilize embedded intelligent algorithms to process operational data for fault prediction, providing a basis for targeted maintenance plans.
A comprehensive management system is the cornerstone of systematic operation and maintenance services. The Clean Energy Company has actively participated in multiple major offshore wind power research projects and deep-sea operation and maintenance initiatives, now possessing full-process capabilities integrating technology R&D and project implementation. Achievements include 26 technical research reports and solutions, 11 patent and software copyright applications, and the compilation and release of 27 floating wind power operation and maintenance management documents. The company has gradually established an offshore floating wind power operation and maintenance management system centered on “management manuals + procedural documents + work instructions,” ensuring more structured management and continuously improving the precision of equipment maintenance.
In recent years, CNOOC Energy Technology & Services has actively promoted the integrated development of offshore oil and gas exploration with new energy. Through the three-dimensional support of “equipment + platform + system,” it has effectively driven the high-quality development of offshore wind power resource exploitation and integrated operation and maintenance capabilities. A series of core-competitive offshore large-scale equipment and supporting technical services have laid a solid foundation for further exploring new models of marine energy development that deeply integrate offshore wind power, energy storage, seawater hydrogen production, and oil and gas production.
