EXPERIMENTAL STUDY ON SCOUR AROUND MONO-PILE FOUNDATION FOR OFFSHORE WIND POWER

Abstract

 This study carried out laboratory experiments to obtain data sets for estimation of the scour around the mono-pile constructed for offshore wind power especially when the water depth is relatively large and KC number is relatively small. The experiment investigated the influence of several factors on observed scour depth, such as the diameter of the mono-pile, incident wave heights and periods, and grain size of the bottom sediment. While obtained results showed the similar relationship of KC number and scour depth to that of the empirical formula presented by the existing studies, obtained scour depth tended to be larger than the ones obtained through the empirical formula.
