SSC kuri NACE TM0177 - nta gucika. PWHT yakoreshejwe ku miyoboro yose kubera serivisi mbi. 100% UT hamwe na TOFD na UT yuzuye umubiri wose (atari umushono gusa). Igenzura rya DNV ry'umuntu wa gatatu mu gihe cyose cyo gukora.

Porogaramu:Umuyoboro wo kohereza imyuka yo mu mazi menshi uva mu murima wa Balder (ubujyakuzimu bw'amazi ni metero 800-1.200) ujya ku kibuga cyo kwakira amazi kiri ku nkombe muri Noruveje. Umuyoboro wa kilometero 38 urimo igice cyo kuzamuka gihinduka (kilometero 2, Ubwinshi bwa mm 25.4) n'inkombe zinyura mu butaka bw'amabuye (kilometero 4, Ubwinshi bwa mm 30).

Ibibazo bya tekiniki n'ibisubizo:

● Ubudahangarwa bwo kugwa mu mazi y'ubujyakuzimu– Ubujyakuzimu bw'amazi kugeza kuri metero 1,200 butanga igitutu cyo hanze cya 12.5 MPa. Umuyoboro wa UOE wa 24″ × 22.2mm ukenewe kugira ngo uhuze n'igitutu cyo kugwa ≥ 25 MPa (igipimo cy'umutekano 2). Womic yakoze imiyoboro ya UOE ifite ovality ≤ 0.2% (yapimwe kuri 0.15-0.18%) n'umuvuduko usigaye ≤ 35% SMYS. Twakoze isesengura ry'ibintu bito (FEA) ku bipimo byo gukora kandi twemeza hakoreshejwe isuzuma ry'umuvuduko wo kugwa ku bipimo bibiri byuzuye (byagezweho 28.5 MPa na 29.2 MPa).

● Serivisi mbi ifite H₂S nyinshi– Gazi irimo 50 ppm H₂S ku bushyuhe bwa 90°C. Amasahani yatoranijwe ya Womic afite karuboni nkeya (C ≤ 0.07%), makeya ya manganese (Mn ≤ 1.40%), makeya ya sulfure (S ≤ 0.002%) hamwe n'ubuvuzi bwa kalisiyumu. CEV yagumanye kuri 0.35-0.38%. PWHT yakoreshejwe ku miyoboro yose (kwibiramo 600°C ± 10°C, igumana amasaha 1.5). Ubukomere nyuma ya PWHT: icyuma cy'ibanze 78-84 HRB, gusudira 82-86 HRB, HAZ 80-84 HRB. Ibizamini bya HIC na SSC byatsinze nta mvune.

● Uburemere bwa CTOD bwo gucika intege ku gikoresho cyo hejuru– Igice cyo kuzamura gisaba gukomera cyane kugira ngo gishobore kwihanganira umuraba. Womic yakoze ikizamini cya CTOD ku byuma byometseho na HAZ kuri -20°C. Ibisubizo: icyuma cyometseho 0.35-0.55mm (≥ 0.25mm kirakenewe), HAZ 0.40-0.70mm (≥ 0.30mm kirakenewe). Twanakoze Charpy y'ubushyuhe buri hasi kuri -46°C (impuzandengo ya 110J). DNV yabonye ibizamini byose bya CTOD.

● Igitambaro gishyushye cyane (3LPP)– Ubushyuhe bwo gukora ni 90°C, naho hejuru ni 110°C mu gihe cyo gufunga. 3LPE isanzwe (polyethylene) igarukira kuri 80°C. Igitambaro cya 3LPP (polypropylene) gishyirwa ku mugore gifite ubugari bwa 3.5mm (urwego rwo hejuru ni 2.5mm + kole 0.5mm + FBE 0.5mm). Igitambaro cyanyuze mu kizamini cyo gukuraho katodike kuri 110°C (umurambararo w'isukari ≤ 8mm nyuma y'iminsi 28). Ingufu zo gukuraho kuri 110°C zipimwe kuri 60 N/cm (nibura 50 N/cm).

● Ubushobozi buhanitse bwo gushyiramo ibyuma birebire– Umuyoboro washyizweho hakoreshejwe uburyo bwo gushyiramo imiyoboro (imiyoboro yashyizwe ku gikoresho cy’imiyoboro). Ibi bisaba kugenzura cyane uburebure bw’umuyoboro (≤ 0.2%) no gushimangira uburebure bw’umuyoboro ≤ 0.5mm. Uburyo bwa Womic bwa UOE bwageze ku uburebure bw’umuyoboro 0.15-0.18%. Twakoresheje imigozi yo gusimbuza kugeza ku burebure bwa ≤ 0.3mm. Imiyoboro yose yatsinze ikizamini cyihariye cyo "gusimbuza": imiyoboro 10 yuzuye yo gusimbuza nta gucika.

● Ibikoresho byo mu bwoko bwa Logistics muri Noruveje– Imiyoboro yoherejwe iva i Shanghai ijya Stavanger, muri Noruveje ikoresheje ubwato bwa break-bulk (ubwato bwihariye bwo gutwara imiyoboro). Kwambuka inyanja y'Amajyaruguru mu gihe cy'itumba byasabaga gupakira ibintu birwanya ubushyuhe. Imifuka ya Womic yakoreshejwe VCI (ibuza ubushyuhe bw'umwuka) hamwe n'ibice bya silica gel biri mu mipfundikizo. Toni 14.000 zose zahageze nta kwangirika cyangwa gupfuka kwangirika.

Ibisubizo:Umuyoboro wa Balder wo kohereza gaze washyizwe mu gihembwe cya gatatu cya 2024. Ishyirwaho ry’umuyoboro (ryakozwe n’umuhanga mu by’ubucuruzi mu mazi) ryagaragaje ko nta kintu na kimwe cyabaye mu miyoboro cyangwa mu gusudira umuyoboro mu gihe cyo gukurura no gushyiramo. Ibirometero 38 byose byatsinze igeragezwa ry’umuvuduko mu nyanja. Umukiriya (umukozi ukomeye wo muri Noruveje) yatanze igihembo cya "Supplier Performance Award" kuri Womic Steel, agaragaza "ubuziranenge budasanzwe n’ibyavuye muri CTOD."
