“…For example, armouring protection has the disadvantage that the projectile cannot be accurately cast in complex sea conditions and is easy to be washed away (Wang et al, 2023;Zhang et al, 2023). Flow-altering protection has the disadvantages of high cost and changing the dynamic characteristics of the foundation (Tang et al, 2023). As offshore struc-tures, wind turbines are vulnerable to corrosion from seawater, which makes the fatigue problem worse (Amirafshari et al, 2021).…”

“…Alabi et al [23] conducted a long experiment of about 40 days, and the results showed that collars can not only reduce the equilibrium scour depth but also slow down the scouring process. To increase the protection efficiency of collars, Tang et al [24] proposed a prediction equation for the equilibrium scour depth of a single pile under collar protection and a formula for the protection efficiency.…”

“…The spoiler mainly affects the direction of water flow to divert it in front of the pile, and its protective effect is affected by the angle of the top corner [28].As for the spoiler structure set in the pile foundation part, we can refer to the scour protection of bridge abutment and consider adopting the simple structure of circular type scour guard ring [29,30]. After the flume test and numerical model simulation studies, it can be determined that a more obvious effect of scour prevention can be discerned [31]. On the basis of the circular type, there are also other forms with more complicated shapes and structures, such as by changing the circular shape into a wing-type washer guard ring [32]; or increasing the thickness of the guard ring to form a neck ring [33] and changing the outer diameter of the guard ring on the basis of the neck ring to form a narrower flare at the top and a wider flare at the bottom [34].…”
