Guodian United Power Technology Co., Ltd. (United Power) launched an offshore energy utilization project to develop tidal current and wind energy. The CNY 5.3 billion Phase 1 includes an experimental prototype tidal current energy project off the coast of Zhoushan, Zhejiang, China, and a wind turbine project offshore of Leting, Hebei, China. Preliminary planned capacity is 300 megawatts, and overall planned capacity is 4,400 megawatts.
Guodian United Power used SACS to design the foundation and support structures. The three-pile jacket-type tidal current set weighed 700 tons. SACS performed modeling, hydrodynamic force calculation, and analysis of working conditions. For the six-pile jacket-type wind turbine set, SACS performed strength analysis, modal analysis, and fatigue analysis. Calculations for 459 fatigue working conditions took only 30 hours, saving labor and material costs.
