The world’s largest offshore wind turbine successfully connected to the grid

SHANGHAI, June 11, 2024 /PRNewswire/ — Envision Energy announced a key achievement in the renewable energy industry with the successful grid connection of the world’s most powerful offshore wind turbine, the EN-256/16.7 prototype. This landmark event marks significant progress in the offshore wind sector and underscores Envision Energy’s unwavering commitment to innovation and environmental stewardship.

Deep sea conditions are extremely demanding, requiring exceptional reliability of high-power wind turbines. EN-256/16.7 is the result of Envision Energy’s extensive in-house research and development, with innovations specifically tailored to deepwater scenarios, from production, delivery, installation, transportation to operation. Its core components have been comprehensively optimized and modernized, increasing power generation efficiency and providing a new solution for the development of offshore wind energy in deep-sea areas.

The deep-sea environment poses unprecedented challenges to the reliability and costs of various aspects of transportation, installation and maintenance of large wind turbines. Addressing issues such as a lack of offshore wind turbine maintenance vessels, high costs, unstable vessel schedules, and long component replacement cycles, Envision Energy incorporated these challenges into the design phase of the offshore turbine model. The product is modular in design and features self-developed tooling interfaces, requiring only simple tools to completely replace components such as the outer cooling core bodies and transformer windings. Modular subcontracting and pre-assembly strategies also free the turbine from the constraints of shipping routes and port capacity, enabling delivery in a variety of scenarios. This approach effectively solves the challenges of transporting and loading large turbines, while minimizing offshore time and increasing installation efficiency.

The successful grid connection of this model, the world’s largest offshore wind turbine, once again demonstrates Envision Energy’s technological expertise and continued impact on the offshore wind industry. As the world looks to the future, the deployment of net-zero megawatt turbines in remote, deep-sea locations is expected to make a significant contribution to global efforts to reduce greenhouse gas emissions.
