He māmā ake te whakahaere i te YT27 mō te whai huatanga i te papaanga, he iti noa te whakangungu e hiahiatia ana mō ngā kaiwhakahaere. Ka hono pai ki ngā werohanga hinu FY250 me ngā waewae FT160A/FT160B; i mua i te whakamahinga, me whakarite kia whakatakotoria te pēhanga hau ki te 0.5-0.63MPa me te pēhanga wai ki te 0.3MPa, kātahi ka tirohia te puna mārama o te werohanga hinu hei whakaū i te pai o te hinu whakahinuhinu. Mā te pūnaha hononga hau-wai whakauru ka taea te keri mākū, ka whakaitihia te nui o te puehu, ā, mā ngā kakau whakahaere pokapū ka taea te whakarite ngāwari i tekeringā tawhā. Whai muri i te mahi, momotu noa i te paipa wai ka whakahaere i te mīhini mō te wā poto hei pupuhi i te makuku toenga, hei ārai i te waikura o roto—he taahiraa iti tēnei e roa ake ai te roa o te mahi a te keri.

He rerekētanga nui te rerekētanga i waenga i te YT27 me ngā keri toka tuku iho mō ngā mahi keri kohatu. He maha ngā wā ka raru ngā tauira tuku iho i ngā pakaru maha i roto i ngā taiao puehu, i ngā taiao rerekē rānei o te pāmahana, ka mutu te mahi whakatikatika mō te 2-3 hāora ia rā. He rerekē, ko te takirere whakahaere flange o te YT27 me ngā wāhanga ātete-kakahu—i rongoatia ki te hangarau wera matatau—i whakaiti i ngā reiti pakaru mā te 70%, kia mau tonu ai te mahi i roto i ngā huringa 8-hāora. I kōrero tētahi keri kohatu ā-rohe nā te huri mai i ngā keri tawhito ki te YT27 i tere ake te keri mai i te 1.2m/min ki te 1.5m/min, ka piki ake te putanga o ia rā mā te 120-150 mita. Ko tētahi atu āhuatanga nui ko te whai huatanga o te pūngao: he 20% te iti iho o te hau e pau ana i te YT27 i ngā tauira tuku iho, e 30% te hekenga o ngā utu pūngao ia marama.

Ko te whakapau kaha o tā mātou wheketere ki te kounga te poutoko mō te pono o te YT27. Ka tirotirohia e mātou te tukanga whakaputa katoa, mai i te kimi i te maitai kounga teitei ki te whakatinana i ngā raina huihuinga aunoa e pupuri ana i ngā reiti hapa i raro i te 0.1%. Ka whakamatautauria ia waeine i roto i ngā āhuatanga o te rua kohatu whakaari, tae atu ki te whakaekenga puehu me ngā huringa pāmahana mai i te -10°C ki te 45°C, kia mau tonu ai te mahi. Ka whakaratohia hoki e mātou he whakamana 12-marama, he tautoko hangarau 24-haora, me te whatunga tuku wāhanga tāpui whānui—ngā ratonga kua whiwhi mātou i te reiti hoko anō a te kiritaki 92%. Mō ngā rua kohatu e rapu ana ki te whakataurite i te whai huatanga, te haumaru, me te whai huatanga utu, ehara te YT27 i te taputapu noa iho; he haumitanga roa e tautokona ana e te kaihanga e mārama ana ki ngā hiahia o te keri kohatu.
