SHIPENGINEERING船舶工程Vol.45No.12023总第45卷,2023年第1期—137—FPSO转塔系泊止链器安装工艺与拖航固定设计琚选择,钟文军,韩少宁,张庆营,黄曙光(海洋石油工程股份有限公司,天津300451)摘要:针对我国南海深水浮式生产储卸油装置(FPSO)转塔单点系泊的关键零件止链器,进行安装工艺过程设计模拟和拖航固定设计的有限元分析。结果表明:止链器集成安装的关键点是吊装过程通过姿态调整与锚链盘U型槽配合;满足止链器安装精度的核心是节圆柱与耳轴转动平稳;止链器拖航固定的张紧链是应力薄弱点,在选型设计中应保守考虑使用1根张紧链的工况。实际工程应用验证了止链器安装工艺与拖航固定设计方案满足可靠性要求,为南中国海类似工程提供了直接经验。关键词:浮式生产储卸油装置(FPSO);单点系泊;转塔;止链器;安装工艺;拖航固定中图分类号:TE951文献标志码:A【DOI】10.13788/j.cnki.cbgc.2023.01.21InstallationProcessandSeaFasteningDesignofChainStoppersforaFPSOTurretMooringSystemJUXuanze,ZHONGWenjun,HANShaoning,ZHANGQingying,HUANGShuguang(OffshoreOilEngineeringCo.,Ltd.,Tianjin300451,China)Abstract:Aimingatthechainstopper,whichisthekeypartofthesingle-pointmooringofthedeepwaterfloatingproductionstorageandoffloading(FPSO)turretintheSouthChinaSea,thedesignsimulationoftheinstallationprocessandthefiniteelementanalysisofthetowingandfixingdesignarecarriedout.TheanalysisshowsthatthekeypointofchainstopperintegratedinstallationisthecoordinationbetweentheattitudeadjustmentandtheU-grooveofchaintableduringthehoisting,andthecoreofrealizingtheinstallationaccuracyofchainstopperisthesmoothrotationofpitchandrollbodyandtrunnion.Thetensionchainfixedbythechainstoppertowingisaweakpointofstress.Theworkingconditionofusingonetensionchainshouldbeconservativelyconsideredintheselectiondesign.Theactualengineeringapplicationverifiesthattheinstallationprocessofchainstopperandthetowingandfixingdesignschememeetthereliabilityrequirements,whichprovidedirectexperienceforsimilarprojectsintheSouthChinaSea.Keywords:floatingproductionstorageandoffloading(FPSO);single-pointmooring;turret;chainstopper;installationprocess;seafastening0引言浮式生产储卸油装...
