Abstract: An effective method using KunZe fluidized solidified soil for anti-scour repair and protection has been widely applied on marine structure and hydraulic engineering in recent years. KunZe solidified soil is a clean, non-toxic material with high performances in multiple physical properties and anti-scour abilities in both fluid and solid (after hardening) state. Different from granular materials such as rocks and sandbags, free-flowing fluidized solidified soil is injected to seafloor area around offshore foundations by pumping operation, filling the scour holes to form low-slope-ratio capping structures with smooth surface for anti-scour protection. Since 2018, anti-scour solidified soil has been successfully applied on more than 700 monopile foundations in various scenarios such as shallow scour holes, deep scour holes with small areas and deep scour holes with large areas around foundations.
