I roto i ngā ahumahi moana me te takutai moana, he whakatau nui te whiriwhiri i te kounga maitai tika, ā, ka pā ki te pakari o te hanganga, te haumaru, me te mahi mō te wā roa. I roto i ngā maitai hanga kaipuke kaha-teitei e whakamahia whānuitia ana,EH36meDH36e rua o ngā momo tino rongonui. He mea hanga ngā mea e rua kia tū atu ki ngā āhuatanga tino kino, engari he rerekē ō rāua āhuatanga miihini, ō rāua tiwhikete, me te pai mō ngā taiao o te Arctic me te moana. Kei roto i tēnei tuhinga he whakataurite taipitopito hei āwhina i ngā kaihangarau, ngā kaihoahoa, me ngā kaiwhakahaere kaupapa ki te whakatau whai whakaaro.
He tirohanga whānui mō EH36 me DH36
EH36He maitai hanga kaipuke kaha-teitei kua whakaaetia e ngā rōpū whakarōpūtanga pērā i te American Bureau of Shipping (ABS) me te Lloyd's Register (LR). Ko te "E" i roto i te EH36 e tohu ana i ngā āhuatanga "Extreme", e tohu ana i te pakari ake i ngā pāmahana iti, e tino pai ana mō ngā tono Arctic.
DH36, i tētahi atu ringa, he maitai kaha-teitei me ngā whakamahinga rite engari i hangaia mō te whakamahinga paerewa ki tai me te moana. He tino pai ngā āhuatanga miihini me te kaha ki te whakarewa, ā, e mōhiotia whānuitia ana mō te whakamahinga i roto i ngā taiao ngawari.
Ahakoa e whakamahia ana ngā momo e rua mō ngā mahi hanga moana, he mea nui kia mārama ki ō rāua rerekētanga i te wā e hoahoa ana i ngā kaipuke me ngā hanganga takutai moana e pāngia ana e ngā kawenga tino makariri me ngā kawenga hihiri.
Ngā Rerekētanga o te Hanganga Matū
He maitai kaha-teitei, he iti te koranu o te EH36 me te DH36, engari he iti noa ngā rerekētanga o te hanganga matū e pā ana ki tā rāua mahi:
-
EH36:Kei roto ko te waro, te manganese, te whūwhā, te whanariki, me te iti o te nikara me te parahi. Ka whakarei ake te hanganga whakahaere i te pakari i te pāmahana iti, ā, ka whakaiti i te ngāwari ki te pakarukaru.
-
DH36:He rite tonu ngā huānga whakarewa, engari he paku rerekē ngā rohe e whakanui ana i te kaha i runga i te pakari rawa atu i te makariri.
He iti noa iho ēnei rerekētanga engari he mea nui, inā koa i ngā āhuatanga o te Arctic e roa ai te wā e pāngia ana ngā rauemi e ngā pāmahana i raro i te koretake.
Whakataurite i ngā Āhuatanga Mīhini
Ko ngā āhuatanga ā-pūkaha o te maitai hanga kaipuke te mea matua hei whakatau i te pai mō te whakamahinga i te Arctic me te moana. E whakaatu ana te whakatauritenga e whai ake nei i ngā rerekētanga matua:
1. Te Kaha Tuku
Ko te kaha tuku e tohu ana i te ahotea e tīmata ai te maitai ki te huri hei kirihou:
-
EH36:Ko te kaha whakaputa iti rawa o te 355 MPa mō te matotoru tae atu ki te 50 mm.
-
DH36:Ko te kaha whakaputa iti rawa o te 345 MPa mō te matotoru tae atu ki te 50 mm.
He nui ake te kaha whakaputa o te EH36, ā, he nui ake te ātete ki te whakarerekētanga tuturu i raro i ngā kawenga tino nui.
2. Kaha Kume
Ko te kaha kume ko te ahotea nui rawa atu ka taea e te maitai te tu atu i te wā e totorohia ana:
-
EH36:Kei waenga i te 490 ki te 620 MPa te kaha o te kume.
-
DH36:Kei waenga i te 470 ki te 630 MPa te kaha o te kume.
He tino pai te mahi kume a ngā momo e rua, engari nā te pumau o EH36 i ngā pāmahana iti iho ka nui ake tōna pono i roto i ngā tono Arctic.
3. Te Kaha Pānga
He mea nui te pakari o te pānga hei ārai i te pakarukaru i ngā taiao makariri:
-
EH36:Ka tutuki i ngā whakamātautau pānga pāmahana iti tino pakari tae noa ki te -40°C, ki raro iho rānei, i runga i ngā whakaritenga a te rōpū whakarōpū.
-
DH36:He pai mō ngā āhuatanga tai ngawari engari he iti ake te pakari o te pānga i ngā pāmahana tino iti.
Nā te pakari o te EH36 i raro i ngā pāmahana iti, koinei te whiringa pai mō ngā kaipuke me ngā hanganga e mahi ana i ngā wai o te Arctic.
4. Te Roroa me te Ngāwari
Ka ine te whakaroa i te ngāwari me te kaha mimiti pūngao:
-
EH36:Ko te roanga iti rawa e 21%, e pai ake ai te mimiti pūngao i raro i ngā kawenga ohorere.
-
DH36:Ko te roanga iti rawa he 19%, he iti ake te ngāwari i te EH36.
Mā te roanga nui ake ka whakarei ake i te mahi a EH36 i roto i ngā āhuatanga hihiri, ngāwari ki te huka.
5. Te āheinga whakarewa
He mea hanga pai rawa atu a EH36 me DH36 mō te ngāwari o te whakarewa. Heoi anō, me āta whakahaere te whakarewa i ngā wāhanga matotoru o EH36 kia mau tonu ai te pakari i te pāmahana iti. He māmā ake te whakarewa i te DH36 i ngā tono paerewa engari kāore pea e tutuki i ngā whakaritenga pāmahana tino iti me te kore he tikanga motuhake.
Ngā tono i roto i ngā taiao o te Arctic me te takutai moana
Ko te kōwhiringa i waenga i te EH36 me te DH36 e whakawhirinaki ana ki te pānga ki te taiao me ngā whakaritenga o te kaupapa:
-
Ngā Mahi Ātiki:Ka whai hua ngā kaipuke pakaru hukapapa, ngā papaaho takutai moana o te Arctic, me ngā kaipuke rangahau wai matao i te pakari pāmahana iti o EH36.
-
Ngā Papaaho o Waho:Ka taea e ngā hanganga tai moana paerewa, ngā kaipuke whānui-waenga, me ngā kaipuke utanga tuku iho te whakamahi pono i te DH36.
-
Ngā Taputapu Moana:Me whakamahi te EH36 i ngā kerēne, ngā papa, me ngā ārai wai i ngā rohe makariri, ā, ka taea e ngā taputapu ōrite i ngā rohe āhuarangi ngāwari te whakamahi i te DH36.
Mā te pakari ake o EH36 ka mau tonu te pumau o te hanganga, ka whakaiti hoki i te mōrearea o te pakarukaru i ngā āhuatanga tino makariri, ā, he mea tino pai mō ngā taiao tino kino.
Te Kōwhiri i te Taumata Rino Tika
I te wā e whiriwhiri ana i waenga i te EH36 me te DH36, whakaarohia ēnei āhuatanga:
-
Ngā Āhuatanga Taiao:Whakatauhia ngā pāmahana whakahaere mōkito rawa me te utanga huka pea.
-
Ngā Whakaritenga Ture:Manatokohia ngā tiwhikete a te rōpū whakarōpūtanga me ngā whakaritenga kaupapa.
-
Te Mahi Mīhini:Aromātaihia te kaha tuku, te kaha kume, te pakari pānga, me te roa.
-
Ngā Whakaaro Hanga:Aromatawai i te āheinga whakarewa, te matotoru o te pereti, me ngā tukanga hanga.
SakySteelE tuku ana i ngā pereti EH36 me DH36 me te kounga kua oti te whakamana, kua tino whaimanahia, ā, kua rite mō ngā tono uaua o te Arctic me te moana. Mā te whiriwhiri i a sakySteel, ka whakarite ngā kiritaki kia whiwhi i ngā pereti maitai mahi-teitei me ngā āhuatanga miihini rite tonu me te tuku pono mō ngā kaupapa nui.
Whakamutunga
He maitai kaha-teitei te EH36 me te DH36 e whakamahia whānuitia ana i roto i te hanga kaipuke me ngā mahi ki tai. He mea motuhake te EH36 mō tōna kaha ki te pāmahana tino iti me tōna pakari ake, he mea tino pai mō ngā taiao Arctic. He whiringa pai tonu te DH36 mō ngā hanganga tai tai me te moana tuku iho, he kaha teitei me te ngāwari ki te whakarewa.
He mea nui te mārama ki ngā rerekētanga o ngā āhuatanga miihini, te hanganga matū, me te pai o te taiao hei whakatau tika. Me ngā kaiwhakarato pono pēnei i asakySteel, ka taea e ngā kaiwhakahaere kaupapa te whakarite kia whiriwhiria e rātou te kounga maitai e tika ana, kia mau tonu ki ngā paerewa o te ao, kia tutuki ai hoki te haumaru me te pakari tino pai.
Mā te arotake i ngā whakaritenga o te kaupapa me ngā āhuatanga taiao, ka māmā ake te whiriwhiri i waenga i te EH36 me te DH36, ka whakarite i te pono o te hanganga me te mahi roa mō ngā kaipuke me ngā hanganga tai moana i roto i ngā taiao moana katoa.
