CITIC Heavy Industries Co

In China's offshore wind market, severe price competition and complex deep-sea geotechnics demanded highly resilient foundations, while disconnected multidisciplinary workflows left CITIC Heavy Industries Co., Ltd. with excessive design conservatism, heavy steel consumption, and prolonged project schedules. Working with Bentley channel partner Beijing 3D Tech Co., Ltd., CITIC adopted a Bentley-centric lifecycle workflow: SACS and OpenWindPower for structural design, bidirectional coupling of SACS and PLAXIS 3D to simulate suction bucket–soil interaction, MOSES for marine installation simulation, MicroStation for drawings, ProjectWise for cross-region collaboration, and an iTwin digital twin tied to structural health monitoring sensors with AI-driven failure prediction. Breaking down professional silos lifted design efficiency by 40% to 50%, shortened design cycles by 20% to 25%, and cut manufacturing rework by 60% to 80% through 3D collision detection. Eliminating conservative assumptions reduced foundation steel by 15% to 25% — 200 to 500 tons and 1.6 to 4 million CNY saved per foundation — avoiding 540 to 900 tons of CO2 per unit, while MOSES-simulated installation cut offshore construction time by 30% to 40%, and the same workflows delivered an 8% to 12% steel reduction on small turbines. The digital twin now lives on as an operations and risk-management asset, extending structural service life by 5 to 10 years, while the equipment delivered generates 1.8 billion kWh of clean power annually and displaces 1.88 million tons of CO2 — proving lifecycle digital engineering as the foundation for competitive, low-carbon offshore wind.
