Located in open sea off the Changle shoreline, Zone C of the Changle Offshore Wind Farm consists of 62 wind turbines, with a total installed capacity of 500 megawatts. The project site presented extreme environmental factors and complicated geological conditions. Fujian Yongfu conducted a feasibility study evaluating the structural integrity and cost-effectiveness of using a suction pile foundation and a conduit frame for the turbines. They realized that their traditional soil simulation and strength assessment methods were not applicable to these pile structures and would result in a significant cost increase.

They selected PLAXIS and SACS for geotechnical and structural analysis and design, offering an integrated digital environment to build a composite model that resolved a series of technical and engineering issues. Using Bentley applications, they confirmed the feasibility of the foundation/frame solution, reducing costs by 30% compared to a conventional foundation structure, saving more than CNY 400 million. They plan to integrate the Bentley iTwin platform to build a digital twin, facilitating intelligent processes within the industry.
