Offshore geotechnics is a multidisciplines area that cover conventional civil engineering disciplines such as fluid mechanics, coastal engineering, geotechnical engineering, structures engineering, etc. This area has attracted great attention among coastal and geotechnical engineers due to growing activities in marine environment worldwide. An appropriate design of foundations of marine infrastructures, such as breakwater, offshore pipeline, platforms, and offshore wind turbine systems plays an important role in the success of offshore engineering projects. The evaluation of the soil response due to hydrodynamic loading, such as waves and currents around foundation of marine structures and its resultant seabed instability is one of the key factors in the design of foundation.

This chapter is an attempt to give a comprehensive review of wave–seabed interaction around the marine structure. It also takes into consideration all state-of-the art knowledge. We start off with the basic models including a detailed review and summary of existing work. Then, we outline recent advances in the field and their engineering applications.
