This project aims to address uncertainties in the design of vibro-driven piles. This promising alternative to impact-driven piles offers faster installation and requires no noise mitigation. The project expects to generate new knowledge of the effect of the installation process in sand on in-service pile response by integrating findings from innovative experiments and numerical modelling. This is particularly important for highly sensitive structures such as offshore wind turbines, which provide a rapidly increasing share of global energy supply. Expected outcomes include practical recommendations for vibro-piles in sand. This should provide sizeable benefits by unlocking vibro-piles as a viable method to reduce offshore wind farm costs.

本项目旨在解决振动沉桩设计中的不确定性。这种有前途的替代冲击桩提供更快的安装，不需要噪音缓解。该项目预计将通过整合创新实验和数值模拟的结果，产生关于砂中安装过程对在役桩反应影响的新知识。这对于海上风力涡轮机等高度敏感的结构尤为重要，因为这些结构在全球能源供应中的份额迅速增加。预期成果包括对砂中振动桩的实用建议。这应该提供相当大的好处，通过解锁振动桩作为一种可行的方法，以减少海上风电场的成本。
