E ai ki te wāhi e whakamahia ana, ka wehea ngā huinga whakaputa hiko tīhi ki ngā huinga whakaputa hiko tīhi whenua me ngā huinga whakaputa hiko tīhi moana. Kua mōhio kē tātou ki ngā huinga whakaputa hiko tīhi mō te whakamahinga whenua. Me arotahi tātou ki ngā huinga whakaputa hiko tīhi mō te whakamahinga moana.
Ko ngā miihini tīhiera moana e whakamahia whānuitia ana i runga i ngā kaipuke, ā, ko ēnei āhuatanga:
1. Ko te nuinga o ngā kaipuke me ngā waka nui e whakamahi ana i ngā miihini tīhiera kaha-rahi, ā, ko ngā poti iti e whakamahi ana i ngā miihini tīhiera iti-mana kāore i te kaha-rahi.
2. Ka mahi te mīhini matua o te moana i te kawenga katoa i te nuinga o te wā, ā, i ētahi wā ka rere i raro i ngā āhuatanga kawenga rerekē.
3. He maha ngā wā ka rere ngā kaipuke i roto i te aueue, nō reira me mahi ngā miihini tīhiera moana i raro i ngā āhuatanga o te koki o te 15° ki te 25° me te rekereke o te 15° ki te 35°.
4. Ko ngā miihini tīhiera tere-iti he miihini rua-whiu te nuinga. Ko ngā miihini tīhiera tere-waenga he miihini whā-whiu te nuinga, ā, kei ngā miihini tīhiera tere-nui ngā mea e rua.
5. Ko ngā miihini tīhiera tere-waenga me te tere-iti te mana nui e whakamahi ana i te hinu taumaha hei wahie, ko ngā miihini tīhiera tere-nui ia e whakamahi ana i te tīhiera māmā.
6. Mena ka peia tika te poroporo, me whakaiti te tere kia pai ai te whakaterenga o te poroporo.
7. Mēnā e hiahiatia ana kia nui te mana, ka taea te whakamahi i ngā miihini maha i te wā kotahi. Mēnā e tere ana i te tere iti, kotahi te miihini matua e ranea ana, ko ētahi atu miihini hei tūnga tatari.
8. Ka peia e ngā miihini tīhiera tere-waenga me te tere-tiketike te poroporo mā roto i te pouaka whakaiti taputapu, ā, ko te pouaka pouaka he hanganga taraiwa whakamuri hei whakatutuki i te whakahurihanga o te poroporo, engari ka taea e te miihini tīhiera tere-iti me ētahi miihini tīhiera tere-waenga te whakahuri i a rātou anō.
9. Ina tāutahia ngā miihini matua e rua ki te kaipuke kotahi, ka wehea kia rua ngā miihini maui me te miihini matau e ai ki te tūranga tāutanga me te urungi o te poroporo.
He motuhake te mahi a ngā huinga whakaputa hiko tīhi moana nā te mea he motuhake te taiao. Ko ngā waitohu miihini moana rongonui o te ao ko Baudouin,Mana Weichai,Cummins, Doosan, Yamaha, Kubota, Yanmar, Raywin etc.
