Wind　energy　is　one　of　the　most　sustainable　and　renewable　resources　for　power　generation.　Offshore　wind　turbines　(OWTs)　derive　significant　wind　energy　compared　to　onshore　installations.　One　of　the　greatest　challenges　encountered　by　installing　the　OWTs　is　the　adequate　design　of　their　foundation　in　relatively　soft　and　compressible　marine　soil.　In　most　cases,　the　OWTs　are　supported　by　a　single　pile,　termed　as　‘monopile　foundation’.　Apart　from　the　usual　loads　from　the　superstructure,　these　piles　are　subjected　to　complex　loading　conditions　under　static　and　cyclic　modes　in　the　axial,　lateral,　and　torsional　directions　due　to　the　primary　actions　of　the　wave,　wind,　and　current.　To　incorporate　an　appropriate　design　methodology,　understanding　the　failure　mechanisms　of　such　piles　is　of　the　utmost　necessity.　This　review　paper　aims　to　focus　on　the　progressive　development　in　the　analysis　of　failure　mechanisms　and　design　practice　relevant　to　the　monopile　foundations　for　OWTs　by　theoretical　and　experimental　studies　conducted　globally.　An　extensive　literature　survey　has　been　carried　out　to　study　the　gradual　progress　on　offshore　pile-soil　interaction,　failure　mechanisms,　and　design　techniques　of　OWT　supporting　monopile　foundations.　Based　on　the　studies,　a　brief　overview　of　the　various　aspects　of　analysis　and　design　has　been　carried　out,　and　the　relevant　conclusions　are　drawn　therefrom.　©　2022　by　the　authors.
