Imininingwane:Iziphetho ezingenalutho (ukusika okuyisikwele), i-coating ye-epoxy ye-coal tar (800 microns), ukuhlolwa kokuthamba (akukho mifantu ekuthambathisweni okungu-1/3 ububanzi). Ukuhlolwa kokugoba okuqondiswayo kokuguquguquka kokuthamba. I-UT engu-100% yomthungo wokuthamba. Umthelela we-Charpy ku-0°C (ubuncane be-27J, kufinyelelwe ku-50-80J). Ukuqonda ≤ 0.2%. Ukuhlolwa komuntu wesithathu yi-SGS Netherlands.

Isicelo:Ukwandiswa kwesiteshi seziqukathi eMaasvlakte 2, ePort of Rotterdam. Izinqwaba zamapayipi ensimbi zisebenza njengesisekelo sodonga lwe-quay (izinqwaba ezithwala umthwalo oqondile) kanye nezinqwaba zamahlengethwa ezibophayo (umthwalo osemaceleni). Ukujula kwamanzi endaweni yokulala: 18m. Inhlabathi yakhiwe yisihlabathi kanye nezendlalelo zobumba oluthambile.

Izinselele Zobuchwepheshe Nezixazululo:

●Ukuvikelwa kokugqwala kwemvelo yasogwini– Ukucwiliswa emanzini anosawoti kanye nendawo yokuchaphaza kwakudinga ukugqoka okuhlala isikhathi eside. I-Womic efakwe i-coal tar epoxy (800 microns DFT) enezendlalelo ezimbili. Ukugqoka kudlule ukuhlolwa kokufuthwa kukasawoti kwamahora angu-3,000 (ASTM B117) okune-<2mm creep evela ku-scribe. Ukutholwa kwamaholide ku-4kV ngaphandle kokwehluleka.

●Izinqwaba ezinde zezindawo zokulala ezijulile– Ubude benqwaba obudingekayo bungu-28m (18m phansi kolwandle + 10m ngaphezu kodaka). Amajoyinti ajwayelekile angu-12m azodinga ama-slices amathathu asensimini. Ama-Womic ahlinzeke ngamajoyinti amade angu-18m (ipuleti eligoqiwe) kuma-pile angu-1,016mm, okunciphisa ama-slices asensimini kusuka ku-3 kuya ku-2 ngenqwaba ngayinye. Kuma-pile abalulekile okubopha, sihlinzeke ngama-pile angu-28m ubude ngokushisela izingxenye ezimbili ezingama-14m (kuhlolwe i-UT engu-100%).

●Ukucindezeleka okuphezulu kokushayela esihlabathini esiminyene– Iphrofayili yomhlabathi ifaka izingqimba zesihlabathi esiminyene ezinamanani e-SPT N angu-40-60. Ukucindezeleka kokushayela inqwaba kufinyelele ku-70% wamandla okukhiqiza. I-Womic yenze izivivinyo zokugoba eziqondisiwe (i-bend radius 4t, 180°) ngaphandle kwemifantu. Amasampula okuhlola okugoba awazange aqhekeke ngemva kokugoba okungu-1/2 ububanzi. Iklayenti libike ukuthi akukho ukwehluleka kokushisela ngesikhathi sokushayela amanqwaba angu-3,200.

●Ukuqina komthelela wokufakwa ebusika– Amazinga okushisa asebusika eRotterdam angehla afike ku--5°C. I-Womic inikeze iBanga lesi-2 ukuqina okuthuthukisiwe kokushisa okuphansi (i-Charpy ku-0°C min 27J, ifinyelele ku-50-80J). Lokhu akudingi yi-ASTM A252 kodwa kwengezwe yiklayenti njengesinyathelo sokuqapha.

●Ukuthunyelwa kwempahla eMaasvlakte– Amapayipi athunyelwa esuka eShanghai eya eRotterdam ngomkhumbi ohamba kancane (izinsuku ezingu-35). Ngenxa yendawo encane yokubeka phansi esikhumulweni, iWomic ihlele ukulethwa kathathu ezinyangeni ezi-4. Ukuthunyelwa ngakunye kwahambisana nesheduli yokushayela yosonkontileka. Wonke amathani ayi-10,800 alethwa ngesikhathi.

● Umphumela:Ukwandiswa kwesiteshi kwaqedwa ngekota yesithathu ka-2024. Zonke izinqwaba ezingu-3,200 zidlule ekuhlolweni komthwalo oguquguqukayo (PDA) ngomthamo wokuthwala odlula izidingo zomklamo. Iklayenti lathi: “Ikhwalithi yamapayipi kaWomic kanye nokuthembeka kokulethwa bekukuhle kakhulu.” I-Womic Steel manje isingumhlinzeki ovunyelwe wamaphrojekthi echweba laseRotterdam esikhathini esizayo.
