Owing to the growth of activities in the marine environment, the phenomenon of fluid–soil structures around marine infrastructures has attracted great attention among coastal and geotechnical engineers. Seabed liquefaction is one of the key failure mechanisms around marine installations such as breakwaters, pipelines, platforms, and offshore wind turbine foundations. Therefore, evaluation of the seabed instability around marine structures is particularly important for engineers involved in the design of foundations of marine infrastructures.
