Ngā Pātai Auau:
P: He aha te rerekētanga i waenga i te ASTM A252 Grade 2 me te Grade 3 mō te whakapūranga pou?
A: He kaha ake te kaha o te Taumata 3 (345 MPa vs 240 MPa te hua) ā, e whakamahia ana mō ngā turanga hohonu ake, ngā kawenga nui ake rānei. He iti ake te utu o te Taumata 2, ā, he rawaka hoki mō te nuinga o ngā tono turanga whānui (piriti, whare, tauranga). Kōwhiria te Taumata 2 mō ngā kawenga paerewa, te Taumata 3 mō ngā kawenga taumaha, te taraiwa hohonu ake rānei.
Q: Kei te tuku koe i ngā paipa A252 Grade 2 me te paninga piauau?
Āe. Kei a mātou te whakapūmau wera-tuku e ai ki te ASTM A123. Ko te roa mōrahi mō te whakapūmau he 12.5m. Mō ngā pou roa ake, ka tūtohu mātou i te paninga epoxy, i te paninga bituminous rānei.
Q: He aha te roa mōrahi ka taea e koe te whakaputa mō te paipa poutū Tau 2?
A: Ko te roa mōrahi o te wāhanga kotahi he 18m (JCOE) 24m rānei (UOE). Mō ngā roa tae atu ki te 60m, ka whakarewahia e mātou ngā wāhanga maha mai i te pito ki te pito me ngā whakarewa porowhita SAW uru katoa (100% UT tirohia). He mea noa tēnei mō ngā monopile hau tai.
P: Me whai whakamātautau wai ā-pūmau te ASTM A252?
A: Kāo. Kāore e hiahiatia he whakamātautau wai-pūmau mō te ASTM A252 nā te mea kāore ngā paipa poupou e ārai i te pēhanga. Heoi, ki te hiahia tō kaupapa ki te whakamātautau wai (hei tauira, mō te poupou me te kawe wai), ka taea e mātou te mahi i tēnei me te utu tāpiri.
Q: He aha te paninga e taunakitia ana mō te whakapuru i te papa moana ki te wai tote?
A: Mō te rumaki ki te wai moana, e taunakihia ana te whakamahi i te epoxy tāra waro (600-800 microns) me te epoxy maramara karāhe rānei. Mō ngā wāhi e tauhiuhi ana ki te wai, e taunaki ana mātou i te paninga FBE, i te epoxy matotoru rānei. Mō te wai māori, mō te oneone rānei, he paipa pango noa, he mata hinu rānei te nuinga o te wā.
P: Me pēhea te whakarite kia ora tonu ngā whakarewa i te wā e whiua ana e te hama?
A: Ka whakahaerehia e mātou he whakamātautau papatahi (me whai tikanga) me te whakamātautau piko ārahi i runga i ngā tauira whakarewa. Mō ngā pou taraiwa nui, ka whakahaerehia hoki e mātou he 100% UT o te hononga whakarewa me te MPI o ngā matimati whakarewa. Ka taea hoki e mātou te whakarato whakamātautau pānga Charpy i te 0°C, iti iho rānei mēnā kua tohua.
P: He aha te roanga o te wā arahi mō ngā paipa whakapuru o te taumata 2?
A: Te wā arataki paerewa: 25-35 ngā rā mō ngā diameter ≤ 1,422mm. Mō te pereti hurihuri diameter nui (> 1,422mm): 35-50 ngā rā. Mō ngā pou roa kua whakarewaina (tae atu ki te 60m): tāpirihia kia 2 wiki.
Tohutoro Kaupapa – Te Whakawhanuitanga o te Taunga Ipu o te Tauranga o Rotterdam (Hōrana)
Whenua:Hōrana (Rotterdam, Maasvlakte 2)
Paerewa me te Taumata:ASTM A252 Tau 2 (me te pānga Charpy tāpiri i te 0°C)
Ngā Ahu me te Rahinga:
●OD 610mm (24″) × T 12.5mm – 24,000 mita (tata ki te 4,500 tāne) i hangaia mā te tukanga UOE
●OD 813mm (32″) × T 16.0mm – 12,000 mita (tata ki te 3,500 tāne) i hangaia mā te tukanga JCOE
●OD 1,016mm (40″) × WT 20.0mm – 6,000 mita (tata ki te 2,800 tāne) i hangaia mā te pereti hurihuri hononga kotahi
Tapeke:42,000 mita (42 kiromita), tata ki te 10,800 tāne
Ngā Whakatakotoranga:Ngā pito papatahi (tapahanga tapawhā), paninga epoxy tāra waro (800 maikorona), whakamātautau whakatārewatanga (kāore he pakaru i te whakatārewatanga 1/3 te whānui). Whakamātautau piko ārahi mō te ngāwari o te whakarewa. 100% UT o te hononga whakarewa. Pānga charpy i te 0°C (iti rawa 27J, tutuki 50-80J). Tika ≤ 0.2%. Tirotiro tuatoru e SGS Netherlands.
Taupānga:Te whakawhānui ake i te taunga ipu i Maasvlakte 2, te Tauranga o Rotterdam. Ko ngā pou paipa rino hei turanga mō te pakitara tauranga (pou amo kawenga poutū) me ngā pou here aihe (uta taha). Te hohonutanga o te wai i te taunga: 18m. Ko te oneone he onepū me ngā paparanga uku ngohengohe.
Ngā Wero Hangarau me ngā Otinga:
●Te tiaki i te waikura o te taiao takutai– I hiahiatia he paninga pakari mō te rumaki wai tote me te rohe tauhiuhi. I pania e Womic te epoxy tāra waro (800 microns DFT) me ngā paparanga e rua. I paahitia e te paninga te whakamātautau rehu tote 3,000 hāora (ASTM B117) me te < 2mm te ngoki mai i te kaituhituhi. Te kitenga hararei i te 4kV me te kore he hapa.
●Ngā pou roa mō te moenga wai hohonu– Ko te roa o te pou e hiahiatia ana he 28m (18m ki roto i te papa moana + 10m i runga ake i te paru). Ko ngā hononga paerewa 12m me toru ngā hononga mara. I tukuna e Womic he hononga 18m te roa (pereti hurihuri) mō ngā pou 1,016mm, ka whakaitihia ngā hononga mara mai i te 3 ki te 2 mō ia pou. Mō ngā pou here tino nui, i tukuna e mātou he pou 28m te roa mā te whakarewa i ngā wāhanga e rua 14m te roa (100% UT i tirotirohia).
●Teitei o ngā ahotea taraiwa i roto i te onepu matotoru– Kei roto i te kōtaha oneone ngā paparanga onepu matotoru me ngā uara-N SPT o te 40-60. Tata atu ngā taumahatanga o te akiaki puranga ki te 70% o te kaha hua. I whakahaerehia e Womic ngā whakamātautau piko ārahi (te radius piko 4t, 180°) me te kore he pakaru. Kāore i whakaatuhia e ngā tauira whakamātautau papatahi te pakaru i muri i te papatahi 1/2 diameter. I kōrero te kiritaki kāore he rahunga whakarewa i te wā e akiakihia ana ngā puranga 3,200.
●Te pakari o te pānga mō te tāutanga hotoke– Ka taea e ngā pāmahana hotoke o Rotterdam te heke ki te -5°C. Nā Womic i whakarato te Womic i te kaha pāmahana iti kua whakarei ake i te Wāhanga 2 (Charpy i te 0°C min 27J, i tutuki i te 50-80J). Kāore tēnei e hiahiatia ana e te ASTM A252 engari i tāpirihia e te kiritaki hei tūpato.
●Te whakahaere ratonga ki Maasvlakte– I tukuna ngā paipa mai i Shanghai ki Rotterdam mā te kaipuke pakaru-rahi (35 rā). Nā te iti o te wāhi whakatakoto i te tauranga, i whakaritea e Womic kia toru ngā tukunga i roto i ngā marama e 4. I whakaritea ia tukunga ki te kaupapa taraiwa a te kaiwhakatū. I tukuna katoatia ngā tāne 10,800 katoa i te wā tika.
● Hua:I oti te whakawhānui i te taunga i te hauwhā tuatoru o te tau 2024. I paahitia e ngā pou katoa e 3,200 te whakamātautau kawenga hihiri (PDA) me te kaha amo i neke atu i ngā whakaritenga hoahoa. I kī te kiritaki: "He tino pai te kounga o ngā paipa a Womic me te pono o te tuku." Kua whakaaetia a Womic Steel hei kaiwhakarato kua whakaaetia mō ngā kaupapa tauranga o Rotterdam a meake nei.
