PowerChina's Qinhuangdao Offshore PV Project is the first and most challenging of its kind in Hebei, facing 35 cm sea ice, high wind, and soft silt in the Bohai Sea. To ensure safety and economy, PowerChina used Bentley SACS and STAAD in an innovative cross-platform collaborative digital twin, creating a “pile-soil-structure” full-system optimization model. This digital approach accelerated the design cycle by 20 days and cut design costs by 22%. Precise, multi-load simulation reduced the truss steel by 18% and pile steel by 15%, while boosting structural resistance to ice and wind loads by 30%. The 342 MW project will generate 403 million kWh annually, saving 175,000 tons of coal and cutting 337,300 tons of CO2 pioneering blue energy development and strongly supporting China's Energy Transition and “Dual Carbon” (peak carbon dioxide emission and carbon neutrality) goals.
