Analysis and interpretation of monitoring data for the seabed bathymetry local to offshore windfarm foundations has shown how the scour develops in time and highlighted variations between sites with different seabed sediment characteristics, i.e. sands and clays. Results from European offshore windfarms have generated a unique dataset for comparison with previously published data. Where surficial sediment is underlain by a marine clay the scour (to date) has been limited, whilst those with unconstrained depths of sandy sediments show scour as deep as 1.38 times the monopile diameter. Scour protection has been installed at some sites for structural stability of the foundation or for cable protection. The flow interaction with the protection causes edge scour or secondary scour in the seabed around the protection. In some cases this scour is deeper than the unprotected case. The analysis has resulted in an improved evidence base for scour in the marine environment.
对近海风电场基础局部海底水深监测数据的分析和解释表明了冲刷如何随时间发展，并突出了具有不同海底沉积物特征（即砂和黏土）的地点之间的差异。欧洲近海风电场的结果生成了一个独特的数据集，可与以前发表的数据进行比较。在表层沉积物下面是海泥的地方，冲刷（到目前为止）是有限的，而那些没有约束深度的砂质沉积物的冲刷深度可达单桩直径的 1.38 倍。为了基础结构稳定性或电缆保护，一些地点已经安装了冲刷防护。保护物与水流的相互作用会导致保护物周围海底的边缘冲刷或二次冲刷。在某些情况下，这种冲刷比无保护的情况更深。该分析为海洋环境中的冲刷提供了更好的证据基础。
