Ocean engineering kila paipu manao a me ke koho ana, kiko'ī e like me ka hoʻokaʻawale 'ana o ka moana 'enekinia kila hale, a me ka kuhikuhi ana i ka API (American petroleum institute), AISC (American hui no ke kila hale), ASTM (American hui o ka ho'āʻo a me nā mea waiwai. ), ANSI (American national standards institute), ASTM (American society of testing and material), AWS (American welding society), NACE (national association of corrosion engineers) standards and guidelines. Koi no ka moana 'enekinia kila paipu mea, nui ka pono o ke kila pā pono'ī, he haʻahaʻa kalapona kila, kiʻekiʻe ikaika kila, ultra-kiʻekiʻe ikaika kila, kuhiliʻole kila eha waeʻano. E haʻi i ʻelua manaʻo ma ʻaneʻi:
(1) ʻenehana moana o nā lako i lawe ʻia mai he nui loa. I kekahi manawa no ka paipu kila Pelekania a me ka hana ʻana i ke kila kila, ʻoi aku ka maikaʻi o nā koi. Ma ka ʻenekinia moana no ka ʻāpana kūikawā o ka paipu kila, ʻo 100% kāna mau koi āpau no ka weld ultrasonic testing (UT – Ultrasonictesting) a me ka nānā ʻana (MT – Magnetictesting). Aia i loko o ka hale nui o ka paipu kila, ma ka laulā o 300 mm ma nā ʻaoʻao ʻelua o ka seam longitudinal pono 100% UT a me MT.
(2) ʻo ka hana ʻana o ka node paipu no ka mea nui i ka ʻenekinia moana. ʻO nā hale hana node paipu kūikawā ma waho, a ua kūkulu ʻia ka hale. Ka nui o 52000 tons, no ka laʻana, "hoaaloha" o ke kai bohai, e lana ana i ka waihona waihona (FPSO, a hoʻomaʻamaʻa i kekahi o ka ʻumi kaulana kaulana o Kina) o ka lima palupalu kūikawā (YOKE) ka YOKE mooring system a me ke kākoʻo bracket, ka hale kiaʻi kukui, kākoʻo helicopter platform, etc. Aia nā 221 nodes, e hoʻokō i nā koi o AISC, AWS. 59 km ka lōʻihi o ka paipu (me ka mamao hoʻomalu hydraulic paipu 28 km, 119 mamao mana valve, pahu pahu 48 alanui). Shipyard i mea e hōʻoia i ka maikaʻi o ke kūkulu ʻana, e koho mai nā kaukani welder he nui o ka welding maikaʻi loa, ʻo ka 15 hope loa i kūpono e like me 6 gr o ka hui papa. I ka ʻenekinia moana i mea e pale aku ai i ka leakage o ka aila a me ke kinoea i loko o ka ʻōnaehana, ʻaʻole i hoʻopaʻa ʻia ka pilina flange kila paipu, a hoʻohana i ka kuʻekuʻe argon arc. ʻEkolu pūʻulu o TIG welder shipyard a pono hoʻomaʻamaʻa kūikawā.
