Gales and gills – The world’s first renewable energy and aquaculture project

Shanghai Electric Wind Power Group has proudly announced the completion of a pioneering offshore renewable energy project, combining floating wind power with deep-sea aquaculture. This landmark project, situated in the National Marine Ranching Demonstration Zone, is located off Nanri Island in the coastal waters of Putian, Fujian Province, China.

The project, developed by Longyuan Power Group with substantial support from the Shanghai Electric Wind Power Group — a subsidiary of the industrial giant Shanghai Electric — showcases a visionary blend of maritime renewable energy technologies and sustainable aquaculture practices. At its core, the design features three semi-submersible floating platforms, each mounted with a 4 MW offshore wind turbine and outfitted with lightweight, flexible solar modules, adeptly tapping into the dual potential of wind and solar power. Beyond this, the platforms include a distinctive element — a hexagonal space at the center for aquaculture — allowing for a seamless integration of energy production with marine cultivation. This novel concept represents a considerable stride forward in the search for energy solutions that are both varied and ecologically harmonious.

Eco-wattage

With the potential to generate an impressive 96,000 kWh of electricity daily when fully operational, the project stands as a testament to the sheer capability of renewable energy sources to meet our needs. To put it into perspective, this output could cater to the daily electricity needs of approximately 9,600 households, assuming an average household consumption of 10 kWh per day, illustrating the project’s significant contribution to energy demands.

Unparalleled testing and reliability

Before reaching operational status, the project was subjected to a rigorous testing protocol, involving nearly 200 different operational scenarios to ensure reliability and safety. This meticulous preparation included the analysis of a 1:40 scale model of the fishing pond, showcasing the thoroughness of the project’s engineering.

To augment the stability and performance of the floating wind turbines, Shanghai Electric Wind Power Group introduced a bespoke intelligent terminal system, setting a new standard in reliability and wind resource optimization.

Technological mastery and expansion

Shanghai Electric has not rested on its laurels with the completion of this project. The company has expanded its reach, signing significant contracts and unveiling new turbines at China Wind Power 2023, namely the EW14.0-263 and EW18.0-263 with their impressive 263-meter-diameter rotor and 18 MW capacity. These developments are based on the cutting-edge Poseidon System, tailored for challenging deep-sea environments.

Adding to their list of achievements, the second quarter of 2023 saw the release of the S98 ultra-long turbine blade. Crafted from lightweight carbon fiber, this blade represents the pinnacle of Shanghai Electric’s research and development efforts, featuring optimized aerodynamics and enhanced corrosion resistance, setting new benchmarks within the industry.
