Q1:Dab tsi tshwj xeeb corrosion nyuaj ua h - ci ci ntsej muag hauv ntug dej ntawm pob hluav taws?
* A1:H - Beams nyob rau hauv txaws zones vim tias muaj kev tsheb ciav hlau tsis tu ncua, uas nrawm} Cov kab sib txuas nrog Flange, kev sib txuas). Cov tshuaj chloride siab hauv dej hiav txwv yog kev txhoj puab heev, txhawb nqa pitting thiab galvanic corrosion yog tias tsis muaj kev sib tshuam ntawm lub nqaj. Yoj cuam tshuam kev cuam tshuam ua rau yaig - corrosion, mechanically tshem cov nplai tiv thaiv lossis txheej txheej. Txwv tsis pub nkag mus rau kev kuaj thiab kho kev tiv thaiv. Cov xwm txheej no tas dag ua kom khov khov ntau {{} txheej txheem xaiv cov tshuab cathodic zoo li siab dua- resistant alloys (CRAS) rau cov cheeb tsam tseem ceeb.
* Q2:Yuav ua li cas yog h - Beams tsim los tiv thaiv nthwv dej cuam tshuam thiab hydrodynamic thauj khoom ntawm jetties?
* A2:Tsim h {- ci rau cov kev yoj yoj muaj kev tsom kwm kev xav nyuaj, lub sijhawm, thiab qauv geometry. Beams yog tshuaj xyuas rau cov kev ntsuas hauv zos siab los ntawm cov nthwv dej thiab cov rog hauv ntiaj teb no. Cov ntu muaj qhov loj me rau qhov tseem ceeb dua los ntawm kev puas hlwb thiab shear fortces inducles los ntawm dej Kinematics. Cov ntsiab lus kev twb kev txuas tau txhawb nqa cov khoom siv hluav taws xob zoo, feem ntau xav tau cov webs tuab, thiab lub sijhawm- Tsis txhob sib txuas. Kev tshuaj xyuas kev poob siab yog qhov tseem ceeb vim Tsheej tau rau ntau xyoo ntawm kev thauj khoom yoj tes rau tus qauv lub neej. Kev rov ua dua thiab muaj zog yog tsim los tiv thaiv kev tiv thaiv zuj zus ntawm kev cuam tshuam hauv ib cheeb tsam kev puas tsuaj hauv zos.
* Q3:Vim li cas Cathodic Kev Tiv Thaiv (CP) feem ntau siv nrog txheej txheej rau submerged h- ci?
* A3:Cathodic Kev Tiv Thaiv (CP) muab cov khoom tiv thaiv zoo rau cov submerged h} Beams uas lub teeb pom kev uas muaj kev puas tsuaj, lossis cov hnub so (pinholes). CP ua haujlwm los ntawm kev ua tag nrho cov cathode tus cathode hauv electrochemical cell, siv antrochemical, tsuas yog siv Anodesial Anodes (zinc, txhuas alloys) lossis cov kev nyiam tam sim no. Qhov no tau kho corrosion ntawm txhua qhov chaw ntawm cov hlau uas raug muab hluav taws xob. Nws tiv thaiv cov geometries zoo li h {4 4}} nqaj profiles qhov twg txheej ntawv thov yog qhov nyuaj. CP cov txheej txheem tau tsim raws cov ntug dej hiav txwv tiv taus, thaj tsam thaj tsam, yuav tsum muaj qhov ceev tam sim no, thiab kev tsim lub neej. Kev tshuaj xyuas kev tiv thaiv ib txwm muaj peev xwm ua kom ntseeg tau lub kaw lus tseem ua tau zoo thoob plaws hauv lub neej pabcuam.
* Q4:Dab tsi yog qhov kev txiav txim siab tseem ceeb rau Cricating h- nqaj nqaj nyob rau hauv ib puag ncig ntawm ntug dej?
* A4:Offshore h - nqaj} nqaj sib txuas lus zoo tshwj xeeb vim muaj kev mob hnyav thiab kev siv tau nyuaj rau kev kho. Cov ntaub thaiv kev yuav tsum tau tswj kev vuam vuam (wpqrs) siv qis - hydrogen cov txheej txheem tiv thaiv kev tawg. Thicker ntu feem ntau yuam preheating preheating thiab post- Weld Kev Kho Mob Kub (PWHT) rau kev ntxhov siab. Qhov seem tsis zoo yog qhov ua kom nruj dua li onshore los xyuas kom meej meej haum - mus rau hauv cov nyom ua rau nkees. Tsis - Kev sim tshuaj (ndt) zoo li automated profile ntsuam xyuas (/) thiab rt) yog qhov siv tau ntau yam ntxiv rau Welds. Cov ntaub ntawv xav tau kho kom zoo (piv txwv li, charpy v- tsis txhob sim kub) kom tawm tsam brittle fracture hauv dej hiav txwv txias. Traceability ntawm txhua cov ntaub ntawv thiab cov txheej txheem yog qhov tseem ceeb.
* Q5:Kev ntsuas rog lub neej sib txawv sib txawv ntawm cov chav nyob ntawm cov khoom ntab hauv qab (FPUS) piv rau cov platform tas li?
* A5:Cov kev ntsuas nkees nkees rau h - cov kab teeb tsa vim muaj kev ywj pheej ntawm cov neeg nyob hauv FPUs Cov lus tsa suab no kom muaj kev thauj khoom ntawm Hull Flex Kev txheeb xyuas cov qauv thoob ntiaj teb tag nrho lub nkoj tag nrho cov lus teb zoo rau cov hiav txwv. Cov kev ntxhov siab hauv zos ntawm kev sib txuas hauv av yog kev tshuaj xyuas siv cov kev ntxhov siab ua ke nrog kev ntxhov siab ntau yam) lossis sijhawm}} Domain simulations. Cov xwm txheej ib puag ncig (yoj scategs daim duab) tshwj xeeb rau kev ua haujlwm yog qhov tseem ceeb tshaj plaws. Tsim lub neej lub hom phiaj yog cov siab ({9}}}}}}} kev nthuav dav thiab cov peev xwm nthuav dav ua tsaug zog ua haujlwm.
