Caqabadaha Farsamada iyo Xalalka:
1. Heerkul aad u daran (-162°C) oo u baahan shaabad lagu kalsoonaan karo oo cryogenic ah– Adeegga LNG ee -162°C (ka hooseeya nitrogen dareeraha ah -196°C) wuxuu u baahan yahay kuraasta PCTFE sababtoo ah sifooyinka shaabadeynta ee aadka u fiican. Womic waxay bixisay kuraasta PCTFE oo leh naqshad tamar gu' ah oo hubinaysa hufnaanta shaabadda iyada oo loo marayo wareegyada kulaylka. Dhammaan 192 waalka ayaa maray tijaabada cryogenic iyadoo heerarka daadashada ay ka yar yihiin 0.05 cc/daqiiqo inji kasta oo dhexroorka kursiga ah.
2. Naqshad dab-badbaado leh oo loogu talagalay adeegga gacanta ee LNG– Hubka dejinta LNG waa isgoysyo badbaado oo muhiim ah. Macmiilku wuxuu u baahan yahay shahaadada API 607 ee dab-badbaadinta dhammaan 16" iyo 12" waalka. Qalabka kaydinta kursiga birta labaad ee Womic ayaa loogu talagalay si loo ilaaliyo shaabadeynta haddii dab dhaco. Tijaabada dabka-badbaadinta waxaa sameeyay oo shahaado siisay shaybaar dhinac saddexaad ah.
3. Xirmo qiiqa soo baxa oo hooseeya si loogu hoggaansamo deegaanka– Terminalka oo ku yaal meel u dhow xarunta dadweynaha ayaa loo baahan yahay ISO 15848-1 Baakad Fasalka B ah. Womic waxay bixisay baakad garaafit ah oo qiiqa yar oo baxsad ah oo leh naqshad bonnet ah oo dheereysa taasoo hubineysa in heerkulka baakadu uu ka sarreeyo -20°C. Shahaadada Heerka B ee ISO 15848-1 ayaa la siiyaa dhammaan waalka.
4. Daawaynta qoto dheer ee cryogenic ee loogu talagalay shubidda waaweyn (16" jirka)– Daawaynta CF3M ee waaweyn (jidhka 16") waxay u nugul yihiin austenite-ka oo la hayo kaasoo sababi kara isbeddel cabbir ah -162°C. Womic waxay samaysay daaweyn qoto dheer oo saddex wareeg ah (-196°C qooyay, 12 saacadood wareeg kasta) iyadoo la kululeynayo dhexdhexaad. Dib-u-eegista cabbirka ayaa xaqiijisay inaysan jirin wax qallooc ah ka dib daaweynta.
5. Naqshad ku rakiban Trunnion oo loogu talagalay waalka 16" iyo 12"– Sida ku cad API 6D, naqshadda ku rakiban trunnion waa qasab cabbirrada ≥ 2" ee adeegga dhuumaha. Womic waxay bixisay waaladaha kubbadda ee ku rakiban trunnion-ka ee laba jibbaaran iyo dhiigbaxa (DBB) oo leh gargaar cadaadis godka ah (hawo-mareenka kursiga sare) si looga hortago cadaadiska xad-dhaafka ah ee ka imanaya fidinta dareeraha ee godka xiran.
6. Kormeerka dhinac saddexaad oo ay samaysay TÜV– Macmiilku wuxuu u baahday TÜV inay markhaati ka noqoto baaritaanka dhammaan 192-ka waalka. Womic waxay la shaqaysaa sahmiyaha TÜV si loo sameeyo baaritaanka hydrostatic, baaritaanka waxqabadka cryogenic (-162°C dareere nitrogen ah), iyo baaritaanka qiiqa baxsadka. TÜV waxay soo saartay shahaadooyin shaqsiyeed waalka kasta 14 maalmood gudahood marka la dhammeeyo baaritaanka.
7. Bixinta waqtiga ku habboon ee jadwalka ballaarinta terminalka– Ballaarinta terminalku waxay lahayd jadwal adag oo aan lahayn wax kayd ah. Womic waxay keentay dhammaan 192-ka waalka 4 shixnadood muddo 12 toddobaad ah, iyadoo shixnad kasta ay ka koobnayd waalka loo baahan yahay marxaladda rakibidda xigta. Shixnaddii ugu horreysay (waaladaha 16" iyo 12") waxay timid 4 toddobaad ka dib xaqiijinta dalabka - ka hor jadwalka. Dib u dhac ku yimid dhismaha ma jirin.
Natiijo:Ballaarinta terminaalka helitaanka LNG si guul leh ayaa loo hirgeliyay 2022. Dhammaan 192-ka waalka kubbadda cryogenic waxay ka shaqeynayeen -162°C in ka badan 2 sano iyada oo aan wax shil ah oo dayactir ah dhicin. Khabiirka waalka macmiilka ayaa yiri: "Waalka cryogenic ee Womic si joogto ah ayuu uga fiicnaa kuwa ka yimid alaab-qeybiyeyaasha Yurub ee la aasaasay marka la eego isku-dhafka wareegga iyo hufnaanta shaabadda. Waxaan hoos u dhignay jadwalka dayactirka sannadlaha ah ilaa 18-bilood." Macmiilku wuxuu soo saaray heshiis 5-sano ah oo ku saabsan dhammaan shuruudaha waalka cryogenic mustaqbalka.
