Tae noa ki tēnei wā, ko ngā whakamahinga cryogenic e hiahia ana kia hiritia te takirere rua-ara kua whakamahia ngā momo takirere e rua, arā, ngā takirere porowhita me ngā takirere pōro pumau/ngā takirere pōro pumau kua mau ki runga. Heoi, nā te angitu o te whanaketanga o te takirere pōro cryogenic rua-ara, kua whiwhi ngā kaihoahoa pūnaha i tētahi kōwhiringa ātaahua ake i ngā takirere pōro tuku iho-ngā takirere pōro e mānu anaHe tere ake te rere, kāore he herenga mō te ahunga rere me te ahunga hiri o te reo, ā, ka taea te mahi haumaru i roto i ngā āhuatanga cryogenic. Ā, he iti ake te rahi, he mama ake te taumaha, ā, he māmā ake te hanganga.
Ko ngā āhuatanga tono cryogenic e hiahia ana ki ngā takirere ko te tomokanga/putanga o ngā tāke rokiroki mō te whakakī me te tukunga, te pēhanga i ngā paipa kau kua kati, te whakapūngao me te wai, ngā paipa maha-kaupapa mō ngā pūnaha rerekē i roto i ngā teihana taunga LNG, ngā pūnaha kaipuke, me ngā waka tāke, ngā pūnaha tohatoha, ngā teihana papu me ngā teihana whakakī wahie LNG, tae atu ki ngā huinga takirere hau māori (GVU) e pā ana ki ngā miihini wahie-rua i runga i ngā kaipuke.
I roto i ngā horopaki tono kua whakahuatia ake nei, ko ngā takirere kati-rua te tikanga e whakamahia ana hei whakahaere me te whakaweto i te wai reo. Ki te whakatauritea ki ngā momo kē atu pēnei i tengā takirere pōro, he maha ā rātou raruraru:
He iti te tauwehenga rere (Cv) - ka pā tēnei ki te kōwhiringa o ngā rahi paipa katoa e tika ana, ā, ka waiho hei ārai pea i te kaha rere o te pūnaha.
· Me whirihora ngā kaiwhakaoho raina hei mahi i ngā mahi kati me te whakahaere - ki te whakaritea ki ngā kaiwhakaoho hurihuri tapawhā e whakamahia ana hei whakahaere me te whakahaere i ngā takirere pōro me ētahi atu takirere hurihuri tapawhā, he uaua ake te hanganga o tēnei momo taputapu, ā, he nui ake te utu. He tino kitea te utu me te uaua o te hanganga o tētahi huinga katoa o ngā taputapu takirere me te kaiwhakaoho.
· Ki te whakamahia te takirere kati hei whakatutuki i te mahi kati ohorere e hiahiatia ana e te maha o ngā pūnaha LNG, ka nui ake te uauatanga.
Mō ngā whakaurunga LNG iti (SSLNG), ka kitea ake ngā raruraru o runga ake nei, nā te mea me iti ake ēnei pūnaha, me iti ake te utu, ā, me nui ake te kaha rere kia taea ai te whakapoto i te huringa uta me te tango.
He teitei ake te tauwehenga rere o te takirere pōro i tērā o te takirere porowhita o te rahi kotahi. Arā, he iti ake te rahi, kāore e pā ki te tere rere. Ko te tikanga tēnei ka tino whakaitihia te rahi, te taumaha me te utu o te pūnaha paipa katoa, tae atu ki te pūnaha katoa. I te wa ano, ka taea e ia te whakanui ake i te hokinga mai o te haumitanga (ROI) o ngā pūnaha e pā ana.
He pono, ko ngā takirere pōro pōro cryogenic paerewa he ara-kotahi, kāore e tika ana mō ngā āhuatanga kua whakahuatia ake nei e hiahia ana kia hiritia te takirere ara-rua.
Ara kotahi, ara rua rānei
E ai ki te Pikitia 1, ko te takirere pōro mānu paerewa mō ngā āhuatanga cryogenic he kōhao whakaora pēhanga kei te taha whakarunga o te pōro takirere hei ārai i te kohikohi me te pikinga o te pēhanga ina huri te āhua o te reo. Ina kati te takirere, ka tīmata te mimiti me te whānui o te hau maori wai i roto i te kōhao o te tinana takirere, ā, ka taea e te rōrahi te eke ki te 600 ngā wā o te rōrahi taketake i muri i te whānui katoa, ka pakaru pea te takirere. Hei ārai i tēnei āhuatanga, ko te nuinga o ngā takirere pōro mānu paerewa kua whakamahi i te tikanga whakaora pēhanga whakatuwhera whakarunga. Nā tēnei, kāore e taea te whakamahi i ngā takirere pōro tuku iho i roto i ngā āhuatanga e hiahia ana kia hiritia ngā taha e rua.
Ā, koinei te wāhanga e taea ai e te takirere pōro pōro cryogenic rua-ara te whakaatu i ōna pūkenga. Ko te rerekētanga i waenga i tēnei takirere me te takirere cryogenic kotahi-ara paerewa ko:
· Kāore he kōhao i te pōro takirere hei whakamama i te pēhanga
· Ka taea te hiri i te wai i ngā taha e rua
· Kāore he kōhao i te pōro takirere hei whakamama i te pēhanga
· Ka taea te hiri i te wai i ngā taha e rua
I roto i te takirere pōro pōro cryogenic ara-rua, ka whakakapia te pūnaha whakawātea pēhanga whakatuwheratanga o runga e te nohoanga takirere puna-ara-rua. Ka taea e te nohoanga takirere puna-uta te tuku i te pēhanga nui i hangaia e te hau maori wai i roto i te kōhao o te tinana takirere, ā, ka ārai i te pakaru o te takirere, e whakaaturia ana i te Pikitia 2.
Hei tāpiritanga, ka āwhina te nohoanga takirere puna-uta ki te pupuri i te taipana o te takirere kia iti ake, kia maeneene ake ai te mahi i roto i ngā āhuatanga cryogenic.
Kei te takirere pōro pōro whakapūmau rua-ara he mowhiti hiri karāhe tuarua-wāhanga, kia whai mahi haumaru ahi ai te takirere. Ki te kore he aituā kino e meinga ai ngā wāhanga pūmua o te takirere kia mura, e kore te hiri tuarua e pā ki te reo. Mēnā ka puta he aituā, ka tutuki i te hiri taumata tuarua te mahi tiaki haumaru ahi.
Ngā painga o ngā takirere ara-rua
Ki te whakatauritea ki ngā takirere porowhita, ngā takirere pōro pumau me ngā takirere pōro pumau kei runga, he pai katoa ngā painga o te takirere pōro tauwehenga rere teitei o te takirere pōro mānu wai-rua, ā, kāore he herenga ki te ahunga wai me te hiri. Ka taea te whakamahi haumaru i roto i ngā āhuatanga wai-rua; he iti te rahi, ā, he māmā noa te hanganga. He māmā noa hoki te kaiwhakaoho ōrite (hurihuri koki-matau) me te iti. Ko te tikanga o ēnei painga he iti ake te pūnaha katoa, he māmā ake, he iti ake te utu.
Ki te whakatauritea ki ngā takirere porowhita, ngā takirere pōro pumau me ngā takirere pōro pumau kei runga, he pai katoa ngā painga o te takirere pōro tauwehenga rere teitei o te takirere pōro mānu wai-rua, ā, kāore he herenga ki te ahunga wai me te hiri. Ka taea te whakamahi haumaru i roto i ngā āhuatanga wai-rua; he iti te rahi, ā, he māmā noa te hanganga. He māmā noa hoki te kaiwhakaoho ōrite (hurihuri koki-matau) me te iti. Ko te tikanga o ēnei painga he iti ake te pūnaha katoa, he māmā ake, he iti ake te utu.
E whakataurite ana te Ripanga 1 i te takirere pōro mānu wairākau rua-ara ki ētahi atu takirere he rite ā rātou mahi mai i ngā tirohanga tiaki, rahi, taumaha, taumata taipana, uauatanga whakahaere, me te utu whānui, ā, e whakarāpopoto ana i ōna painga me ōna ngoikoretanga.
Mena ka takahia e tētahi whare LNG iti te tikanga, ā, ka whakamahia he takirere pōro cryogenic rua-ara, ka taea e ia te whakamahi katoa i ngā painga ahurei o te takirere pōro, arā, te whānui katoa, te tere rere teitei me te tere tuku paipa teitei. I te taha whakataurite, ka taea e ia te tautoko i ngā paipa iti ake me te pupuri tonu i te tere rere ōrite, kia taea ai e ia te whakaiti i te rōrahi katoa, te taumaha, me te uaua o te pūnaha, ā, ka taea hoki e ia te whakaiti i te utu o te pūnaha paipa.
I roto i te tuhinga o mua, i whakaurua ngā painga o te whakamahinga hei takirere kati. Mēnā ka whakamahia hei takirere whakahaere, ka kitea ake ngā painga. Mēnā ka whakamahia te takirere pōro hurihuri koki-matau, ka tino whakaitihia te uauatanga o te kete aunoatanga takirere, nō reira kua waiho hei taonga whiriwhiri mō te pūnaha cryogenic.
Ko te mea tino taketake o te kete aunoatanga kua whakahuatia ake nei ko te takirere pōro pōro cryogenic rua-ara māmā me te whai hua, me te actuator hurihuri tapawhā he hanganga māmā me te utu nui.
I roto i te poto, he "whakahē" te hiranga pai o te takirere pōro cryogenic e rua-ara mō te pūnaha paipa cryogenic. I roto i ngā whakaurunga LNG iti, ka taea e ia te whakamahi katoa i ōna painga.
I ngā tau kua taha ake nei, kua manatokohia tēnei hua hou i roto i ngā mahi tūturu, e whakaatu ana he mea pai tēnei mō te utu o te kaupapa me te whakahaere pono o te pūnaha mō te wā roa.
