In　the　transitional　waters　of　30　to　90　m,　jacket　foundation　has　great　application　potential　due　to　its　advantages　of　light　weight,　high　structural　stiffness　and　good　stability.　In　addition　to　the　long-term　normal　wind　and　waves,　the　wind　turbines　will　suffer　from　typhoons　and　waves　in　extreme　bad　weather.　Currently,　research　on　the　dynamic　response　of　jacket　supported　OWTs　in　clay　under　severe　typhoons　is　very　rare.　The　study　develops　a　numerical　method　to　calculate　the　dynamic　response　and　fatigue　damage　of　jacket　supported　OWTs　under　typhoon　loads　by　incorporating　a　simplified　single　bounding　surface　model　of　clays.　Through　three-dimensional　numerical　analysis　across　various　scenarios,　this　study　investigates　the　dynamic　response　characteristics　of　jacket　supported　OWTs　on　clay　soil.　It　also　examines　the　impact　of　wind-wave　coupling　effects　on　the　fatigue　damage　experienced　by　these　structures.　It　was　found　that　severe　typhoons　can　lead　to　notable　permanent　tilting　of　the　jacket　foundation,　thereby　failing　to　meet　the　requirements　of　normal　serviceability　limits.　The　most　critical　nodes　of　the　OWT　are　situated　at　the　mudline　of　the　pile　foundations,　followed　closely　by　the　bottom　of　the　tower　structure.　The　most　significant　fatigue　damage　occurs　for　wind-wave　co-directional　coupling　loading　along　the　orthogonal　direction　of　the　OWT.　The　research　outcomes　provide　valuable　guidance　for　enhancing　the　typhoon-resistant　design　of　jacket　supported　OWTs.
