The UK is the world leader in offshore wind energy; almost 40% of global capacity is installed in UK waters. A new ambitious target of 40GW of wind power by 2030 aims to produce sufficient offshore wind capacity to power every home, helping to achieve net zero carbon emissions by 2050. Offshore wind turbine (OWT) foundations, which are typically steel monopiles, contribute approximately 25% to a windfarm's capital cost. The size of OWTs is increasing rapidly and continued optimisation of foundation design is paramount. Recent research has led to significant advances through theoretical developments combined with high-quality field-testing. Despite recent advances, there remains significant uncertainty in the measurement and interpretation of key soil deformation parameters that underpin new and existing design approaches. The central aim of SOURCE is to use rigorous measurement and interpretation in the field and laboratory to quantify and reduce material parameter uncertainty and minimise the impact on the predictive capability of OWT foundation design methods. Improved site characterisation will contribute to increased security in design, lowering capital costs, subsidies and carbon emissions and meeting the UK's ambitious new energy targets.

英国是海上风能领域的世界领导者；全球近40%的容量安装在英国水域。一个新的雄心勃勃的目标是到2030年风力发电达到40GW，旨在生产足够的海上风力发电能力，为每个家庭供电，帮助到2050年实现净零碳排放。海上风力涡轮机（OWT）的基础通常是钢单桩，约占风电场资本成本的25%。wot的规模正在迅速增加，基础设计的持续优化是至关重要的。最近的研究通过理论发展和高质量的现场测试取得了重大进展。尽管最近取得了进展，但在支持新的和现有的设计方法的关键土壤变形参数的测量和解释方面仍然存在很大的不确定性。SOURCE的中心目标是在现场和实验室中使用严格的测量和解释来量化和减少材料参数的不确定性，并最大限度地减少对OWT基础设计方法预测能力的影响。改善场地特征将有助于提高设计安全性，降低资本成本、补贴和碳排放，并实现英国雄心勃勃的新能源目标。
