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 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.
This project was a finalist in the Mining and Offshore Engineering category of the 2021 Going Digital Awards in Infrastructure, and an ES(D)G Honoree for Affordable and Clean Energy.
