S-spar平台垂荡板数目确定及立管系泊系统耦合分析 一、引言 Offshorewindenergyhasbecomeincreasinglyattractiveinrecentyearsduetoitssignificantpotentialasarenewableenergysource.Sparplatforms,whicharecommonlyusedinoffshorewindturbineinstallations,havebeenrecognizedasaneffectivesolutiontoharvestenergyfromthesea.Inthispaper,wefocusonthedesignandanalysisofthemooringsystemofsparplatforms,payingparticularattentiontothecouplingeffectsbetweenthemooringlinesandtherisersunderdynamicconditions. 二、Spar平台垂荡板数目确定 Thedesignofasparplatformtypicallyinvolvesthedeterminationofthenumberofoscillatingplatesrequiredtoensureadequatestabilityandstructuralintegrityunderdifferentoperatingconditions.Itisnoteworthythattheperformanceofthesparplatformishighlysensitivetothenumberofoscillatingplatesused. Thestabilityofthesparplatformisprimarilydeterminedbyitscenterofgravity(COG)inrelationtoitsbuoyancycenter(BC).Asageneralrule,thehighertheCOGrelativetotheBC,themorestablethesparplatformwillbe.Toachievetherequisitestability,designersgenerallyaimtoplacetheCOGashighaspossible.Thiscanbeaccomplishedbyincreasingthenumberofoscillatingplates,aseachplatecontributestotheoverallplatformheight.
