Shasteel's High-End Steel Enables Offshore Wind Power to Achieve Dual Breakthroughs in “Greatest Depth” and “Greatest Distance”

Recently, the Huaneng Shandong Peninsula North L site and the Three Gorges Jiangsu Dafeng offshore wind projects have both achieved full-capacity grid connection, setting important milestones for China's offshore wind power sector as the “deepest water depth” and “furthest offshore distance” projects, respectively. In this pivotal journey toward deeper waters, Shasteel Group has leveraged its robust technological expertise and reliable supply capabilities to deliver over 80,000 metric tons of high-performance wind power steel for various projects, providing solid material support for China's offshore wind power development.

The Huaneng Shandong Peninsula North L Site Project pushed offshore wind operation depths to 53 meters. Its 83.9-meter-tall four-pile jacket foundation set a new height record for similar structures in China, marking a major leap in the nation's capability to develop offshore wind power in deeper waters. Shagang developed and supplied over 30,000 tons of high-performance wind power steel plates specifically for this project, ensuring the reliability and durability of its critical foundation structures.

The Three Gorges Jiangsu Dafeng 800-megawatt project deploys wind turbines in offshore waters 85.5 kilometers from the coast, making it China's most distant large-scale offshore wind farm to date. This milestone not only imposes stringent demands on the long-term stable operation of wind turbine equipment but also comprehensively tests integrated engineering capabilities in deep-sea construction, installation, and subsequent operation and maintenance. Shasteel supplied over 50,000 tons of high-end wind power steel for this project, safeguarding this deep-sea energy “voyage” with exceptional product performance.

Confronting the severe corrosion, loads, and complex operating conditions of deep-sea environments, Shasteel leveraged its independently developed core metallurgical technology system to successfully resolve the balancing challenge between multiple demands for high-end wind power steel—including strength, toughness, corrosion resistance, and weldability. This system deeply integrates cutting-edge technologies such as “precision control of austenite across the entire temperature range” and “multi-level, multi-phase microstructure toughening control.” It enables the stable, large-scale production of high-performance wind power steel suitable for extreme environments like sub-zero temperatures and deep offshore conditions. Authoritative evaluations confirm that the overall technology has reached internationally leading standards.
