Me whakahaere rawa te āhua porowhita (≤ 0.2%) me te teitei o te whakakaha whakarewa ≤ 0.5mm. I whakahaeretia te āhua porowhita ki te 0.08-0.15% me te whenua i ngā taupoki whakarewa ki te teitei ≤ 0.3mm. E 10 ngā huringa whakatauira takai tauine-katoa i mahia e mātou ki runga i te paipa whakamātautau – kāore he ngatata, he hekenga rānei o te āhua porowhita.
6. Arotakenga me te tuhi tuhinga mō te DNV– I kite ngā kairūri o te DNV i ngā whakamātautau wai-pūmau, CTOD, HIC, SSC, me te tirotiro i ngā āhuatanga mō ia puranga. I whakaratohia e Womic he kōnae kounga 1,500-whārangi (tae atu ki ngā pūrongo whakamātautau katoa, ngā tūtohi PWHT, ngā rangitaki UT, me ngā hainatanga a ngā kairūri) i roto i ngā wiki e 4 o te tukunga. I whakaaetia te kōnae me te kore he pātai.
7. Hua:I angitu te tāutanga o te paipa i te hauwhā tuarua o te tau 2025 mā te whakamahi i te ipu whakatakotoranga-rīra Deep Constructor. Kāore i puta he rahunga o te tinana paipa, he rahunga hononga whakarewa rānei i te wā o te whakakoi, te whakatinanatanga, te whakamātautau rānei i muri i te whakatakotoranga. I kī te kaiwhakahaere kaupapa a te kiritaki: "I hipa ake ngā hua o te mana whakahaere ovality me te CTOD a Womic i ā mātou tumanakohanga. I whakarewahia tonutia ngā paipa i te parae me te 98% o te reiti whakaae tuatahi." Kei runga inaianei a Womic Steel i te rārangi kaiwhakarato kua whakaaetia mō ētahi atu kaupapa kaweake hau hohonu e rua i Āwherika ki te Hauāuru.
