“…This aspect has been reported in past studies by Qi & Gao [21,22], that as the velocity around the circular monopile increases, while keeping the other parameters constant, there is a corresponding increase in the Froude number [43]. This increase in the flow velocity generates greater turbulence in the vicinity of circular monopile, leading to the formation of additional eddy currents and streamlines [44][45][46][47]. Consequently, this augmented turbulence and increased streamlines result in a faster movement of bed particles, ultimately leading to a deeper scour hole formation nearer to the circular monopiles [9,48].…”

“…However, the operating environment of the underwater energy storage accumulators is Separation vortices generated by the ocean current around the gas storage accumulator will erode the soil near the foundation, thereby affecting its stability. Therefore, it is important to understand the local scouring characteristics and predict the scouring depth around the foundation [95,96]. Protection measures for controlling local scour should be investigated after clarifying the mechanism of local scour around the foundation.…”

“…The findings from these tests reveal that, when subjected to low KC numbers, the actual damage inflicted on the scour protection layer is notably less severe than what the KC numbers had initially predicted. In addition, the research reported in [11] unveils an additional phenomenon, i.e., waves also have a substantial influence on the soil pore water pressure, causing cyclical fluctuations in the soil pore water pressure and even triggering seabed liquefaction in extreme cases. This phenomenon clarifies why sediments atop the seabed surface are more susceptible to erosion under the combined influence of tidal currents and waves, thereby imposing a substantial threat to OWTs.…”
