Ib qho Kev Sib Tw Tsis Txaus Siab los ntawm hla lub Atlantic
Thaum lub caij nplooj ntoo hlav xyoo 2025, Ms. Sophie, Tus Thawj Coj Kev Lag Luam ntawm Fab Kis Marine Engineering tuam txhab hauv Brittany, tau tshaj tawm cov lus nug tshwj xeeb rau cov neeg xa khoom thoob ntiaj teb. Ntawm 81 technical parameters rauAPI 5L X60 PSL2 SSAW steel kav, yam 37 tau sau tseg tshwj xeeb: "Thov ua pov thawj cov txheej txheem xaiv rau Φ1200mm yeeb nkab nrog phab ntsa thicknesses ntawm 25mm thiab 27mm."
Thaum tus email no tuaj txog thaum 2:00 AM, peb Tus Thawj Coj Kev Ua Haujlwm, Mr. Chen, tau tshuaj xyuas cov ntawv tshaj tawm txog kev cuam tshuam ntawm Charpy tshiab. Nws tam sim ntawd lees paub tias qhov no tsis yog kev nug txog kev yuav khoom niaj hnub tab sis yog kev twv txiaj ntsig txog kev ua tau zoo ntawm qhov tob - cov kav dej hiav txwv.
A 120-hnub Technical Exchange
Hauv plaub lub hlis tom ntej no, Sophie pab pawg tau tsa 47 cov lus nug tseem ceeb. Feem ntau cov neeg sawv cev sib pauv tau tshwm sim hauv lub lim tiam thib tsib:
"Vim li cas 25mm phab ntsa thickness siv kauv vuam, thaum 27mm yuav tsum tau longitudinal seam vuam?"
Peb siv peb lub lis piam npaj plaub txheej ntawm cov ntaub ntawv txhawb nqa:
- Ib qho kev txheeb xyuas qhov kawg nkaus -raws li simulation daim ntawv qhia txog weld stress distribution.
- Ib tug lej qauv ntawm kev sib raug zoo ntawm kauv yeeb nkab winding lub kaum sab xis thiab phab ntsa thickness.
- Cov ntaub ntawv sib piv los ntawm kev sib sib zog nqus -sea pressure cycling test rau ob txoj kev.
- Cov ntaub ntawv pov thawj txheej txheem rau peb JCOE longitudinal seam vuam ntau lawm kab.
- Txhua cov lus teb tau xa tuaj tsis pub dhau 30 feeb, tab sis cov ntaub ntawv kev tshaj lij feem ntau tshaj 20 nplooj ntawv. Sophie tom qab sau ntawv hauv email: "Koj cov lus teb ceev thiab qhov tob tob tsim ib qho kev sib txawv zoo sib xws."
Technical validation nyob rau hauv lub Rhiav
Thaum Lub Xya Hli, Sophie tau mus xyuas Tuam Tshoj tus kheej. Nyob rau hauv pem teb rhiav, nws thov kom muaj ib tug nyob ua qauv qhia ntawm lub expansion txheej txheem rau ib tug 25 hlikauv-welded yeeb nkab. Raws li hydraulic system thawb lub taub hau expansion los ntawm lubAPI 5L X60 PSL2 SSAW steel kav, nws siv ultrasonic thickness gauge coj 12 sib law liag ntsuas ntawm ob sab ntawm lub vuam.
"Ib lub thickness sib txawv ntawm 0.3mm," nws hais thaum tshuaj xyuas cov ntaub ntawv. "Qhov no yog nruj dua li koj tus qauv cog lus ntawm 0.5mm."
Tom qab ntawd, ntawm txoj kab ntev seam vuam ntau lawm, nws tau tsom mus rau kev soj ntsuam JCO txheej txheem rau 27 hli steel phaj. "Tam sim no kuv nkag siab," nws hais, taw rau lub phaj dabtsi yog khoov. "Thaum lub thickness ntau tshaj 26 hli, qhov kev ntxhov siab ntxiv los ntawm kauv winding cuam tshuam rau cov khoom siv isotropy, qhov kev loj hlob ntawm kev sib txuas hauv longitudinal vuam khaws cov khoom qub."
Los ntawm Technical Recognition mus rau Strategic Partnership
Kev sib tham txog daim ntawv cog lus tau siv sijhawm peb hnub, tab sis kev lees paub cov lus pom zoo tsuas siv peb teev xwb. Tom qab Sophie pab pawg kws tshaj lij thiab peb cov kws ua haujlwm tau txheeb xyuas tag nrho 87 qhov kev ntsuas tsis raug kab los ntawm kab, nws xaum ib daim ntawv hla lub rooj sib tham:
"Qhov no yog cov txheej txheem kev uas peb tau npaj rau North Hiav Txwv cov roj thiab roj qhov project, Ameslikas npaj raws li lub hauv paus kev lees paub. Tam sim no, kuv thov kom peb txais nws raws li peb cov qauv kev sib koom ua ke."
Cov ntawv txuas ntxiv no, uas muaj 216 cov ntsiab lus tshuaj xyuas, thaum kawg tau los ua qhov tseem ceeb ntawm daim ntawv cog lus. Qhov kev txiav txim 8,616.25-tuj, 30% kev them ua ntej, thiab kev koom tes nrog peb lub xyoos tau ua tiav tag nrho yav tav su.
Kev cog lus zoo hauv qab Dej Hiav Txwv
Niaj hnub no, cov noAPI 5L X60 PSL2 SSAW steel kavtau ua haujlwm nyob rau hauv North Seabed rau rau lub hlis. Lub lim tiam dhau los, peb tau txais thawj cov ntaub ntawv qhia txog kev ua haujlwm los ntawm Sophie pab pawg, tsuas yog ib kab lus hauv cov lus hais:
"Tus nqi CTOD ntawm qhov vuam hauv -2℃dej hiav txwv yog 18% siab dua li daim ntawv cog lus yuav tsum tau ua."
Hauv kev lag luam no, kev ntseeg tseeb yeej tsis raug tsim los thaum lub sijhawm cog lus kos npe. Nws yog tsim thaum cov khoom, dag 300 meters hauv qab dej hiav txwv, ntsiag to validate txhua yam kev cog lus ua thawj zaug. Txhua qhov weld yog cog lus; txhua millimeter ntawm phab ntsa tuab yog lub luag haujlwm-qhov no yog qhov kev pom zoo zoo uas peb tau tsim nrog peb cov neeg siv khoom Fabkis hla 8,000 mais.
