Waxay leedahay baahiyo tamar badan iyo dheereyn (20% daqiiqo) waxayna u dulqaad badan tahay rarista saameynta inta lagu jiro wadista dubbe. API 5L X52 sidoo kale waxaa loo isticmaali karaa tuulmada, laakiin Heerka 3aad waa heerka warshadaha ee tuulmooyinka aasaaska ee Waqooyiga Ameerika iyo mashaariic badan oo caalami ah.

S: Ma keeni kartaa tuulmooyin ka dheer 18m?
J: Haa. Waxaan isku dhejin karnaa qaybo badan oo 12m ama 18m ah si aan u soo saarno dherer ilaa 60m. Alxan kasta oo wareegsan waa 100% UT la baaray waxaana la baari karaa RT marka la codsado. Tuubooyinkan dhaadheer waxaa badanaa loo isticmaalaa monopiles-ka dabaysha ee badda (dhererka 30-50m).

S: Waa maxay dhumucda derbiga ugu badan ee tuubada LSAW ee Fasalka 3aad?
J: Tolmo hal-labo ah oo saxan duuban ilaa 100mm, tolmo laba-labo ah sidoo kale ilaa 100mm. Dhumucda derbiga ee ka sarreysa 100mm (tusaale ahaan, 120mm), fadlan nala soo xiriir si aad u hesho qiimeyn mashruuc oo gaar ah. Waxaan bixinnay tuulmo 120mm WT ah oo loogu talagalay aasaaska biyaha qoto dheer ee gaarka ah.

S: Tuubooyinkani ma u baahan yihiin baaritaanka hydrostatic-ka?
A: ASTM A252 uma baahna tijaabinta hydrostatic sababtoo ah tuubooyinka tuulmada ma laha cadaadis. Si kastaba ha ahaatee, haddii mashruucaagu u baahan yahay tijaabinta hydrostatic (tusaale ahaan, isku-darka tuulmada iyo gaadiidka dareeraha), waxaanu ku samayn karnaa kharash dheeraad ah.

S: Dahaarka noocee ah ayaa lagu talinayaa in lagu shubo badaha?
A: Deegaannada biyaha badda, dhuxusha daamurka epoxy (dhumucdeedu waa 600-800 microns) ama epoxy galaas ah ayaa caadi ah. Meelaha aagga daamurka, waxaan kugula talineynaa FBE ama 3LPE oo leh iska caabin dheeraad ah oo xoqidda ah. Biyaha cusub ama carrada, tuubo madow oo caadi ah ama dusha sare ee saliidda leh ayaa badanaa ku filan.

S: Sidee baad u hubisaa in alxanka uu ka badbaado wadista dubbe?
A: Waxaan sameynaa 100% UT oo ah tolmo alxan ah oo lagu daray MPI (baaritaanka walxaha birlabta ah) ee faraha alxanka si loo ogaado dildilaac kasta oo dusha sare ah. Waxaan sidoo kale sameynaa tijaabooyin la hagayo oo ku saabsan muunadaha alxanka si loo xaqiijiyo isku-xidhka. Tuubooyinka muhiimka ah ee la wado, waxaan sidoo kale ku bixin karnaa tijaabada saameynta Charpy heerkul ah 0°C ama ka hooseeya.

S: Waa maxay waqtiga caadiga ah ee hogaanka ee tuubooyinka fasalka 3aad ee tuulmada?
J: Waqtiga caadiga ah ee rasaasta: 30-45 maalmood dhexroorka ≤ 1,422mm. Tuubooyinka saxanka ee dhexroorka weyn ee la duubay (> 1,422mm): 45-60 maalmood. Tuubooyinka dhaadheer ee la alxamay (ilaa 60m): ku dar 2-3 toddobaad alxanka wareegsan iyo kormeerka.

Tixraaca Mashruuca - Ballaarinta Dekadda Konteenarada ee Dekadda Houston

Dalka:Mareykanka (Houston, Texas)
Heerka & Darajada:ASTM A252 Fasalka 3 (oo leh saameyn dheeraad ah oo Charpy ah 0°C)
Cabbirka iyo Tirada:

●OD 914mm (36″) × Miisaan 19.0mm – 18,000 mitir (qiyaastii 7,600 tan) oo ay soo saartay habka JCOE

●OD 1,067mm (42″) × Miisaan 22.2mm – 9,000 mitir (qiyaastii 4,600 tan) oo lagu sameeyay tolmo hal saxan ah oo la duubay

●OD 1,219mm (48″) × Miisaan 25.4mm – 3,500 mitir (qiyaastii 2,500 tan) oo lagu sameeyay tolmo hal saxan ah oo la duubay (oo loogu talagalay meelaha biyaha qoto dheer)
Wadarta:30,500 mitir (30.5 km) oo ah tuulmo, qiyaastii 14,700 tan

Tilmaamaha:Cidhifyo cad (gooyn afar geesle ah) oo leh dahaar, dahaar epoxy ah (500 microns, nooca epoxy dhuxusha) si loo ilaaliyo daxalka biyaha marinnada maraakiibta Houston ee jilicsan. Tijaabada simida qasabka ah (ma jiraan dildilaacyo ka dib simida dhexroorka 1/3). Tijaabada leexashada ee hagitaanka ee isku-xidhka alxanka. 100% UT oo ah tolmo alxan ah oo lagu daray 10% RT dhibic. MPI oo ah suulasha alxanka. Saamaynta jilicsan ee 0°C (ugu yaraan 20J, 40-60J caadiga ah). Kormeerka dhinac saddexaad oo ay samaysay SGS.

Codsiga:Ballaarinta Terminalka Konteenarrada ee Bayport ee Dekadda Houston. Mashruucu wuxuu ku lug lahaa dhismaha laba meelood oo cusub (derbi dhan 1,200m oo ah deyr dhuleed) oo leh meel lagu kaydiyo konteenarrada dhulka. Tuubooyinka birta ah waxay u adeegaan aasaaska qaab-dhismeedka sagxadda shubka ah (tuulooyinka culayska qaada ee toosan) iyo tuulmooyin taageero ah oo dahaar ah (rarka dhinaca). Qoto dheer ee biyaha ee meelaha la dhigo: 16m.

Caqabadaha Farsamada iyo Xalalka:

●Deegaan biyo ah oo daxal leh– Kanaalka Ship-ka ee Houston wuxuu leeyahay koloriin sare (10,000-18,000 ppm) iyo pH hoose (6.5-7.0) oo ay ugu wacan tahay qulqulka warshadaha. Dahaarka dhuxusha ee lagu dahaadhay biyaha (600 microns DFT) oo leh laba lakab: primer (200 microns) + topcoat (400 microns). Dahaarka wuxuu dhaafay 3,000 saacadood oo tijaabo ah oo lagu buufiyo milix (ASTM B117) oo leh < 2mm crop. Ogaanshaha fasaxa waxaa lagu sameeyay 3.5kV iyadoo aan wax cillado ah dhicin.

●Cadaadis sare oo wadista ah oo ku yimaada ciidda cufan– Qaabka carrada ee terminaalka wuxuu ka kooban yahay ciid cufan oo ciid ah oo leh qiimaha caadiga ah ee gelitaanka (SPT) N-qiimaha 30-50. Cadaadiska wadista tuulmada wuxuu ku dhawaaday 80% xoogga wax soo saarka. Womic waxay samaysay tijaabooyin leexasho hagitaan ah oo ku saabsan kuubannada alxanka (kala-goynta 4x dhumucda, 180°) iyada oo aan lahayn dildilaacyo. Waxaan sidoo kale bixinnay MPI alxanka tuulmo kasta 50-aad si loo hubiyo inaysan jirin dildilaacyo suulka ah. Qandaraaslaha wadista tuulmada ee macaamiisha ayaa soo sheegay inaysan jirin alxan jaban intii lagu jiray rakibidda 2,100 tuulmo.

●Dhererka tuulmada dheer ee meelaha biyaha qotoda dheer laga qodo– Meelaha ugu qoto dheer ee loo baahan yahay tuulmooyin loo kaxeeyo qoto dheer oo ah 32m (20m oo loo geliyo badda hoosteeda + 12m oo ka sarreysa dhoobada). Kala-goysyada caadiga ah ee 12m waxay u baahan doonaan 3 tuulmooyin oo goob ah tuulmo kasta. Womic waxay bixisay isku-xidhyo dhererkoodu yahay 18m (tolmo hal saxan ah oo la duubay) tuulmooyinka 1,067mm iyo 1,219mm, taasoo yaraynaysa kala-goysyada goobta laga bilaabo 3 ilaa 2 tuulmo kasta (waxay badbaadinaysaa 35% waqtiga alxanka). Waxaan sidoo kale bixinnay tuulmooyin dhererkoodu yahay 36m oo loogu talagalay nidaamka fender-ka (looma baahna kala-goysyo) annagoo alxanayna laba qaybood oo 18m ah dhammaadka-ilaa-dhammaadka oo leh SAW oo si buuxda loo galiyay iyo 100% UT.

●Adkaanta saameynta wadista jiilaalka– Heerkulka jiilaalka ee Houston wuxuu hoos ugu dhici karaa -5°C. Darawalka tuulmada ee heerkulka hooseeya wuxuu halis u yahay jab jab. Hooyada ayaa siisay Heerka 3aad adkeysi heerkul hoose oo la xoojiyay: Saamaynta qurunka 0°C ugu yaraan 20J (heerka A252 uma baahna baaritaan saameyn ah). Natiijooyinka dhabta ah: 45-65J heerkulka 0°C, 35-50J heerkulka -10°C. Macmiilku wuxuu tan ku daray shuruud aan qasab ahayn laakiin faa'iido leh.

●Bixinta Saadka ee waqtiga ku habboon– Goobta dhismaha waxay lahayd dhul xaddidan oo la dejin karo (oo keliya 8,000 mitir oo laba jibbaaran). Womic waxay qorsheysay afar shixnadood (qiyaastii 3,700 tan midkiiba) muddo 5 bilood ah. Tuubooyinka waxaa lagu geyn jiray markab jabsada oo ka yimid Shanghai una socda Houston, ka dibna waxaa lagu geyn jiray xamuul dhan 200 tan labadii toddobaadba mar. Kooxda saadka ee Womic waxay la xiriirtay maamulka dekedda si ay mudnaanta u siiyaan dejinta iyo rarista gawaarida xamuulka ah, iyagoo ka fogaanaya kaydinta dekedda. Dhammaan shixnadaha waxay yimaadeen ±3 maalmood gudahood taariikhihii loo qorsheeyay.

●U hoggaansanaanta ka-dhaafitaanka Iibsashada Ameerika– Mashruuca Dekadda Houston wuxuu u baahday ka dhaafitaan birta shisheeye sababtoo ah wax soo saarka gudaha ee Mareykanka ma buuxin karin jadwalka. Womic waxay bixisay dukumentiyo faahfaahsan oo ay ku jiraan shahaadooyinka warshadda, waddanka laga soo jeedo, iyo raad-raaca agabka. Ka dhaafitaanka waa la ansixiyay, dhammaan 14,700 tanna waxay fasaxeen Kastamka Mareykanka iyadoo aan wax dib u dhac ah la sameyn.

● Natiijo:Ballaarinta Terminalka Konteenarrada ee Bayport waxaa la dhammeeyay rubuci saddexaad ee 2024, ka hor jadwalka. Dhammaan 2,100 oo tuub oo bir ah ayaa ka gudbay tijaabada culayska (tijaabada culayska taagan ee 5% tuubyada: dejinta < 10mm marka la eego culayska naqshadeynta 2x). Maamulka dekeddu wuxuu soo sheegay inaysan jirin cillado tuub ama arrimo dahaar ah. Womic Steel waxay heshay abaalmarin "Alaab-qeybiye Waxqabad Sare" oo ka timid qandaraaslaha guud (shirkad injineernimo madani ah oo weyn oo Mareykan ah). Terminalku hadda wuu shaqeynayaa, isagoo maamula 1.5 milyan oo TEU ah sannadkii.
