Ocean engineering zitsulo chitoliro kamangidwe ndi kusankha, specifications ndi malinga ndi gulu la ocean engineering zitsulo kapangidwe, ndi ponena za API (American petroleum Institute), AISC (American gulu zitsulo dongosolo), ASTM (American gulu kuyesa ndi zipangizo ), ANSI (American National Standards Institute), ASTM (American Society of Testing and materials), AWS (American welding society), NACE (National Association of corrosion engineers) miyezo ndi malangizo. Kufunika kwa nyanja uinjiniya zipangizo zitsulo chitoliro, kwenikweni ndi chofunika mbale zitsulo palokha, ali otsika mpweya zitsulo, mkulu mphamvu zitsulo, kopitilira muyeso-mkulu mphamvu zitsulo, zosapanga dzimbiri magulu anayi. Tchulani mfundo ziwiri apa:
(1) uinjiniya wam'madzi wa zida zotumizidwa kunja kwambiri. Nthawi zina ku Britain zitsulo chubu ndi zitsulo chubu kupanga makamaka mkulu khalidwe zofunika. Mu uinjiniya wa m'nyanja ndi gawo lapadera la chubu lachitsulo, 100% zake zonse zimafunikira pakuyezetsa akupanga (UT - Ultrasonictesting) ndi kuyang'anira maginito (MT - Magnetictesting). Kuphatikizidwa mu dongosolo lalikulu la chitoliro chachitsulo, mumtundu wa 300 mm pa malekezero onse a msoko wotalika amafuna 100% UT ndi MT.
(2) kupanga nodi ya chitoliro ndi ya zinthu zofunika kwambiri mu uinjiniya wa m'nyanja. Special chitoliro mfundo mafakitale kunja, ndi zoweta anamanga wagawo. Kutha kwa matani a 52000, mwachitsanzo, "ubwenzi" wanyanja ya bohai, unit yoyandama yosungiramo zinthu (FPSO, ndi kuphunzitsa imodzi mwazotumiza khumi zodziwika kwambiri ku China) za mkono wapadera wofewa (YOKE) ndi njira yolumikizira YOKE ndi bulaketi yothandizira, nsanja ya torch, thandizo la nsanja ya helikopita, etc. Pali ma node a 221, kuti akwaniritse zofunikira za AISC, AWS. 59 km kutalika (kuphatikizapo remote control hydraulic chubu 28 km, 119 valavu yoyang'anira kutali, msewu wa tank 48). Sitima yapamadzi kuti muwonetsetse kuti zomangamanga zili bwino, sankhani kuchokera ku zikwizikwi za kuwotcherera kwabwino kwambiri, omaliza 15 amayenerera kukhala 6 gr gulu lamagulu. Mu nyanja zomangamanga pofuna kupewa kutayikira kwa mafuta ndi gasi dongosolo, si anatengera zitsulo chitoliro flange kugwirizana, ndipo utenga argon Arc kuwotcherera. Magulu atatu a TIG welder shipyard ndipo amafunikira maphunziro apadera.
