China Launches World's Largest Offshore Converter Station

TL;DR

  • •The 2-GW 'Haifeng Heart' is the largest offshore converter station globally.
  • •It will annually supply 6 billion kWh of renewable energy.
  • •Six world records were set during its construction.

Why it matters

This project advances offshore wind energy transmission by reducing losses over long distances and enabling access to deep-water wind resources.

Technical Specifications

The 2-GW 'Haifeng Heart' platform, measuring 85.5 meters in length and 82.5 meters in width, was shipped to Jiangyin's coastal waters. Weighing 25,000 tons, it will annually generate 6 billion kWh of renewable energy by linking two offshore wind farms to China's grid.

Development Context

Built by Shanghai Zhenhua Heavy Industries (ZPMC), the project employed parallel construction methods for the frame, equipment integration, and internal assembly. Six records were set:

  • Maximum capacity: 2 GW.
  • Voltage record: Uses the world's highest VSC-HVDC system.
  • Hybrid AC/DC integration: First of its kind in offshore wind.

Industry Impact

Converting AC to DC minimizes transmission losses over distances exceeding 100 km, enabling access to remote wind resources. ZPMC experts noted this project will become a benchmark for deep-sea wind farms, accelerating the shift to green energy.
