With　the　continuous　development　of　offshore　wind　power　and　clean　oil　fields,　the　introduction　of　wind　power　into　the　offshore　oil　and　gas　field　energy　system　has　attracted　much　more　attention.　As　an　oil　and　gas　production　platform　with　both　production　capacity　and　energy　consumption,　on　the　premise　of　ensuring　stable　production,　the　adoption　of　an　economical　and　reasonable　energy　device　design　scheme　will　not　only　help　to　reduce　the　construction　cost,　but　also　can　promote　energy-saving　and　emission　reduction.　In　this　paper,　the　economic　and　environmental　performance　of　the　energy　system　for　three　scenarios　including　traditional　energy　system,　DES　without　wind　energy　access　and　DES　with　wind　energy　access　are　simulated　by　building　a　new　robust　optimization　model　for　energy　system　that　takes　the　minimum　annual　total　cost　of　the　energy　system　as　the　objective　function.　The　impact　of　wind　power　access　platform　grid　on　the　DES　is　comparatively　analyzed　in　detail.　Taking　an　oil　production　platform　in　the　Pacific　as　an　example,　the　results　show　that,　while　wind　power　access　reduces　carbon　emissions　by　approximately　39.91%,　it　can　also　reduce　the　total　annual　cost　of　the　system　by　approximately　2.57%.　At　the　same　time,　through　sensitivity　analysis,　we　found　that　there　is　an　optimal　ratio　57.04%　of　wind　energy　based　on　economy　which　is　influenced　by　crude　oil　price.　In　addition,　the　effects　of　uncertain　parameters　including　energy　demand,　associated　gas　production　and　wind　power　are　compared　and　analyzed,　which　can　provide　risk　mitigation　support　for　decision　makers.　?　2021　Elsevier　Ltd.　All　rights　reserved.
