On June 23, the “Haiyang Shiyou 511” high-speed wind operation and maintenance vessel independently designed and built by China was delivered in Yangjiang, Guangdong, marking a new step in China National Offshore Oil Corporation’s (CNOOC) offshore wind power operation and maintenance capabilities.
As CNOOC’s first high-speed offshore wind operation and maintenance vessel, “Haiyang Shiyou 511” was jointly built by CNOOC Development Clean Energy Company and domestic shipbuilding companies, which aims to provide strong technical service support for the green and low-carbon transformation of energy.
The wind operation and maintenance vessel delivered this time adopts a catamaran design, which can provide better stability and load-bearing capacity. The total length of the vessel is 36.2 meters and the width is 10.4 meters. It has the ability to safely lean against the wind turbine piles under a significant wave height of 2.5 meters. The vessel can effectively addresse the problems of complex sea conditions, harsh environment and time constraints in deep sea wind power operation and maintenance operations. It offers high safety, accessibility, and comprehensive functionality, making it suitable for use in a wide range of sea conditions across various marine environments.
Meanwhile, with a speed of up to 18 knots, the vessel can quickly reach the location of wind turbines that require maintenance and promptly repair or replace equipment. This reduces downtime, improves the overall operational efficiency of wind farms, lowers maintenance costs, enhances emergency response capabilities, and ensures the stable operation of wind farms and maximizes power generation efficiency.
In order to fully utilize the efficiency of operation and maintenance vessels, CNOOC independently developed a smart new energy management platform, equipped with digital intelligent decision-making assistance equipment, to promote wind power operation and maintenance from experience-driven to data-driven. The platform can continuously optimize the dispatch of operation and maintenance vessels according to the three modes of shortest time, lowest cost and highest efficiency, combined with the sea conditions and weather data of the target operating area based on artificial intelligence algorithms, and automatically generate scheduling plans for vessels between operation and maintenance home ports, oil and gas platforms, and offshore wind farms, effectively improving the rationality of scheduling and improving the efficiency of offshore wind power operation and maintenance.
In recent years, CNOOC has accelerated the integration of new energy and traditional energy, focused on deep sea wind power and other fields, and continued to explore new paths for differentiated development of the new energy industry. The commissioning of “Offshore Oil 511” will inject new strong momentum into CNOOC’s active promotion of high-quality offshore wind power resource development and accelerated cultivation and development of new marine energy productivity.
