    Nā paipu kila SSAWhana ʻia me nā ʻōwili kila ʻokiʻoki ma ke ʻano he mea maka, hoʻopuka ʻia ma ka mahana mau, a hoʻopaʻa ʻia e ke kaʻina hana hoʻoheheʻe arc submerged pālua ʻelua ʻaoʻao. Hōʻoia kēia ʻenehana hana hou i nā pae kiʻekiʻe loa o ka pololei a me ke kūpaʻa, e hana ana i kā mākou mau paipu kūpono no nā noi laina wai honua.

    Paipu No ka laina wai ma lalo o ka honua

    ʻO ka puʻuwai o kēiapaipu kila ʻōwiliʻo ia kona hoʻolālā wili kū hoʻokahi. Hoʻokomo ʻia ke kila kila i loko o ka mea paipu i hoʻopili ʻia a ʻōwili mālie ʻia e nā wili he nui e hana i kahi paipu poepoe hakahaka me kahi hakahaka wehe. Loaʻa iā ia ka hiki ke hoʻoponopono i ka nui o ka hōʻemi o ka wili extrusion, a hiki ke hoʻomalu ʻia ka hakahaka weld ma waena o 1-3mm e hōʻoia i kahi pilina paʻa a paʻa. Eia kekahi, ua kūlike pono nā wēlau ʻelua o ka hui i hoʻopili ʻia, e hāʻawi ana i kahi hoʻopau kūpono.

    He nui nā ʻano o nā paipu kila SSAW e hoʻokaʻawale iā lākou mai nā paipu kila kuʻuna. Loaʻa i kona ʻano wili ka ikaika maikaʻi loa a me ke kūʻē ʻana i nā mana o waho, e hōʻoiaʻiʻo ana i ka palekana a me ka hilinaʻi o ka ʻōnaehana hāʻawi wai. Eia kekahi, ʻo ke kaʻina hana kuʻihao kiʻekiʻe e hōʻoiaʻiʻo ana he pale leak nā hui a pale i ka seepage a i ʻole ka haumia. Me kona kūkulu paʻa a me nā pilina paʻa, hōʻoia kēia paipu i ka hana lōʻihi a hoʻemi i nā pono mālama, e lilo ia i hopena kūpono no kekahi papahana laina wai honua.
