Novel Project Combines Offshore Wind Power, PV and Aquaculture

0

Longyuan Power Group has completed what it says it the world’s first maritime renewable energy project that combines deep-sea floating wind energy and aquaculture.

Along with partner Shanghai Electric Wind Power Group, which provided the power generation equipment and turbine towers, Longyuan built the project within the National Marine Ranching Demonstration Zone on Nanri Island, located in Putian, Fujian Provence of China.

The project features three-column semi-submersible floating platforms, each one supporting a 4 MW offshore wind turbine and flexible solar modules that are installed in the area with a water depth of around 35 meters. A hexagonal space within the platform’s central area can be used for fish farming.


The mixed energy project has the capacity to generate 96,000 kWh of electricity daily at full capacity. The companies say this “pioneering convergence of wind power, photovoltaics,and aquaculture presents a new horizon for the industry.”

During the phase of the preliminary design, Shanghai Electric Wind Power Group established an integrated model that was confirmed through a multi-round consistency analysis. Other measures, including simulation result comparisons across various platforms and the development of control algorithms in partnership with DVN, also strengthened the safety and reliability of the project.

The entire project has also undergone an extensive range of rigorous testing across nearly 200 operational conditions, including a 1:40 scale model used for examining the fishing pond. , Shanghai Electric Wind Power Group also developed a custom-built intelligent terminal system for floating wind turbines, enhancing reliability to ensure the safe and consistent operation of the turbines while maximizing wind utilization.
