He mea maʻamau ka hoʻohana ʻana i nā paipu kila i ka ʻenekinia moana.Aia ma kahi o ʻekolu ʻano paipu kila i loko o nā ʻōnaehana nui ʻelua o ka hana moku a me ka ʻenekinia moana: nā paipu kila i nā ʻōnaehana maʻamau, nā paipu kila i hoʻohana ʻia i ke kūkulu ʻana, a me nā paipu kila no nā kumu kūikawā. Loaʻa i nā moku like ʻole a me nā papahana moana nā ʻōnaehana maʻamau a me nā ʻōnaehana kūikawā.

ʻO ke ola lawelawe o nā moku ma kahi o 20 mau makahiki, a ʻo ke ola lawelawe o nā paipu kila ma ka ʻenekinia moana hiki ke piʻi ma kahi o 40 mau makahiki. Ma waho aʻe o nā ʻōnaehana maʻamau, aia pū kekahi ʻōnaehana hoʻoheheʻe kūikawā a me nā ʻōnaehana hana, a me nā ʻōnaehana kahe ʻana no ka ʻaila ʻaila, liquefied petroleum gas a me liquefied natural gas i waho o ka ʻenehana.
Ma o ka helu ʻana, ʻike ʻia ka ʻai makahiki oʻO nā paipu kila humuhumu pololei ke anawaena nui (LSAW)no ka hoʻohana moana he 5 miliona mau tona, ma kahi o 500,000 paipu, kahi o 70% o nā paipu kila e pili ana. He 300,000-tone wale no ka pahu aila nui loa e hiki ke hoohana i na kakini kilomika o na paipu kila a me na paipu paipu, a o ka paipu kila ma kahi o 1,000-1,500 tona. ʻOiaʻiʻo, ʻo ka nui o nā paipu kila i hoʻohana ʻia i ka hoʻolālā hull o 40,000 tons he mau palena. Eia kekahi, i ka noʻonoʻo ʻana i nā ʻano moku like, he nui nā moku ʻē aʻe e kūkulu. No ka 300,000-ton super-nui FPSO, ʻoi aku ka nui o nā paipu ma mua o 40,000 a ʻoi aku ka lōʻihi ma mua o 100 mau kilomita, ʻo ia ka 3-4 mau manawa o ka tonnage like. No laila, ua lilo ka ʻoihana moku i mea hoʻohana nui i ka ʻoihana paipu kila.

ʻO ka paipu kila kūikawā: pili i ka paipu kila kūikawā i hoʻohanaʻia ma kahi kūlana hana kūikawā a me keʻano hana. ʻO ka pipeline oil submarine he paipu kila kūikawā maʻamau, i makemake nui ʻia a loaʻa nā hiʻohiʻona o ka ikaika kiʻekiʻe, ka hoʻomanawanui liʻiliʻi a me ke kūpaʻa corrosion maikaʻi.

Ma waho aʻe o nā ʻōnaehana maʻamau a me nā ʻōnaehana kūikawā i ʻōlelo ʻia ma luna nei, hoʻohana ʻia nā paipu kila humuhumu pololei i ka paia i loko o nā hale he nui, e like me nā ʻaʻahu, nā puʻu kila ma lalo o ka wai, nā casings, mooring brackets, helicopter channels, flare towers, etc. ʻO kēia ʻano manoanoa- pā pololei seam paipu kila he nui kiko'ī, kiʻekiʻe maka mea, a me ka ia anawaena, okoa anawaena, okoa paia mānoanoa, Y-type, K-type, T-type paipu ami. E like me nā ʻaʻahu, nā puʻu kila, nā ʻaʻahu wai punawai, a me nā mea ʻē aʻe.

Ma waho aʻe o nā koi nui o nā paipu kila humuhumu pololei me ka pā mānoanoa, ʻoi aku ka kiʻekiʻe o kāna mau koi ʻana i ka corrosion. Ma muli o ka ʻike ʻia ʻana o ka paipu kila i ka wai a me nā ʻano media like ʻole i ka wai no ka manawa lōʻihi, ʻoi loa ka ʻino o ka paipu kila, no laila pono e mālama ʻia ka paipu kila humuhumu me ka pā mānoanoa.kuʻi-corrosionma mua o ka hoʻohana ʻana.
