Akukho ukuhlolwa kwemvelouhlelo lokusekela ikhebulangendlela ulwandle olusebenza ngayo. Epulatifomu elingasogwini lolwandle, i-FPSO, noma isitshalo senqubo yasogwini, umkhathi ugcwele usawoti, unomswakama, futhi uvame ukushisa; izakhiwo ziyathuthumela futhi ziyanyakaza; futhi imiphumela yokwehluleka kokusekelwa okugqwalile kusekethe ebukhoma ilinganiswa ngokulahlekelwa komkhiqizo kanye nengozi yokuphepha, hhayi izindleko zokulungisa. I-Shanghai Qinkai Industrial Co., Ltd., umenzi wethreyi yekhebula ejwayelekile ye-NEMA kanye nezinhlelo zethreyi yekhebula, ithi amaphrojekthi asemanzini nawasogwini yiwona aqhutshwa kakhulu yizincazelo: abathengi lapho abaceli “ithreyi yekhebula” - bacela izinga lezinto ezibonakalayo, uhlelo lokumboza, isigaba sokugqwala, kanye nemibhalo yokufakazela konke lokhu okuthathu.
“Ogwini, ithreyi yekhebula ivame ukuba yimpahla kagesi. Ogwini, kuyisici esibalulekile sokuphepha kwesu lokugqwala kwempahla,” kusho inkampani esitatimendeni. “Ulwandle aluxoleli indlela enqamulelayo. Amakhasimende ethu asemanzini achaza izinhlelo zensimbi ezifakwe ngogesi noma ezingenasici ezishisayo ngedatha yomthwalo eshicilelwe, futhi ahlola umbiko wokumboza ngaphambi kokuhlola ukuthunyelwa.”
Yini eyenza isimo sasolwandle sihluke
I-logic yobunjiniyela iqala ngendawo ezungezile. Izindawo zasemanzini zihlukaniswa phakathi kwezinto ezingcolisa kakhulu esikalini se-ISO 12944 — isigaba C5-M sezindawo zasogwini nezisogwini olunosawoti omningi, kanti i-CX igcinelwe ukuchayeka kakhulu ogwini lolwandle. Izindlela ezintathu zibangela umonakalo:
Ukufakwa kukasawoti. Izinhlayiya zikasawoti eziphuma emoyeni zihlala emsebenzini wensimbi, futhi lapho kunomswakama zakha i-electrolyte enamandla ehlasela i-zinc nensimbi ngokufanayo.
Ukumanzisa okujikelezayo. Izakhiwo zasogwini lolwandle zihamba ngemijikelezo emanzi-eyomile njalo - ukufutha, imvula, ukujiya, kanye nenkungu kasawoti - futhi umjikelezo ngamunye usheshisa ukugqwala ezifweni zokumboza kanye nemiphetho yokusikwa.
Ukucindezeleka kwe-chloride. Ama-chloride ahlasela izembozo ezihlanganisiwe kanye nensimbi yekhabhoni ngokushesha kakhulu kunokungcola kwangaphakathi, yingakho ukujiya kwezembozo kanye nokukhethwa kwezinto, hhayi amashejuli okulungisa upende, kunquma impilo yesistimu.
Umphumela osebenzayo ukuthi izinhlelo zethreyi ezifakwe ngogesi noma ezipendiwe ezivame ukufakwa endlini eyomile azinandawo ekucacisweni kolwandle. Amaphrojekthi alinganisa insimbi efakwe ngogesi eshisayo ngokwe-EN ISO 1461 noma i-ASTM A123, noma ensimbini engagqwali — ngokuvamile i-Type 316 — ngenxa yokuchayeka okukhulu kakhulu kanye nezindawo zemishini lapho ukufinyelela kokugcinwa kwesikhathi eside kunqunyelwe khona.
Amapulatifomu alungisiwe kanye nama-topside e-FPSO
Ezinkundleni eziqinile zasogwini kanye nezindawo zokukhiqiza ezintantayo, uhlelo lokusekela ikhebula luyisimiso sezinzwa sale mpahla.Izintambo zikagesiimishini yenqubo yokuphakela, izitimela zokucindezela, kanye nokupompa; izintambo zezinsimbi nezokulawula ziphethe izimpawu zokulawula inqubo, izinhlelo zokuphepha, kanye nokuvalwa okuphuthumayo. Zombili zihamba emizileni eminyene, enamazinga amaningi ngokusebenzisa amamojula aphezulu lapho isikhala sabelwe khona yi-millimeter.
Izidingo ezintathu zibusa ukucaciswa kwengxenye ephezulu. Okokuqala, ukungenisa umoya: izindawo zokucubungula zikhiqiza ukushisa, kanti ukwakhiwa komoya kwethreyi nezinhlelo zeladi ezisezingeni eliphezulu kuvumela izintambo ezinamandla ukuthi zikhiphe ukushisa ngenkathi kugcinwa yonke ikhebula ibonakala futhi ilandelelwa ukuze ihlolwe. Okwesibili, ubuqotho bomshini: uhlelo kumele lubambe umthwalo walo olinganiselwe ngaphansi kokunyakaza kwepulatifomu, ukudlidliza okuvela emishinini ejikelezayo, kanye nokuphambuka kwesakhiwo sepulatifomu uqobo - yingakho amatafula omthwalo ashicilelwe ngobubanzi, iphimbo le-rung, kanye nesikhala sokusekela kuyisidingo esithambile kunokuba kube lula kwikhathalogi. Okwesithathu, izinto zokwakha: ukwesekwa kwekhebula elingaphezulu endaweni yokuchaphaza kanye nezindawo zokucubungula kuchazwe kakhulu ku-Type 316 stainless steel noma i-hot-dip galvanized steel, kuye ngefilosofi yomqhubi yokugqwala, lapho ukufinyelela kokulungisa kunzima khona noma lapho izindonga ezilinganiselwe ngomlilo nokuqhumisa kumele zingene khona ngokuhlanzekile.
Imikhumbi kanye nemikhumbi yokusekela ogwini lolwandle
Imikhumbi kanye nemikhumbi yokusekela yasogwini lolwandle yengeza inkambo ehlukile: isitifiketi. Izinhlelo zokusekela ikhebula ezifakwe emikhunjini ehlukanisiwe ngokuvamile zingaphansi kwemithetho yenhlangano yokuhlukanisa - i-DNV, i-ABS, i-Lloyd's Register phakathi kwazo - futhi ukufakwa kumele kulandelelwe ezintweni ezivunyiwe kanye nemidwebo. Izindawo zemikhumbi zihlanganisa nokudlidliza okuqhubekayo, umzila ovalekile phakathi kwamagumbi enjini kanye nezikhala zobuchwepheshe, kanye nesidingo sezinhlelo ezingashintshwa ngezikhathi zedokhi elomile ngaphandle kokwenziwa okukhethekile ebhodini.
Ngenxa yalezi zizathu, umsebenzi womkhumbi uthanda ithreyi eliboshwe ngamabholidi, elibhotshoziwe ngaphambilini kanyeizinhlelo zezitebhisienobubanzi obuphelele bokufakwa - ama-gond, ama-tee, ama-cross, ama-reducer, nama-drop-out units - ngakho-ke umzila ungalungiswa kabusha ngehadiwe ejwayelekile namathuluzi esandla. Ubukhulu obuncane nobude besigaba obubikezelwayo bubalulekile njengokusebenza kokugqwala, ngoba isikhala ngaphakathi kwezikhala zobuchwepheshe zomkhumbi sincane kakhulu kunanoma yisiphi isitshalo esisogwini.
Umoya ongaphandle kolwandle
Amapulazi omoya aphesheya kwezilwandle andisa imithetho efanayo yokugqwala emkhakheni okhula ngokushesha. Izinqaba, izingcezu zokuguquka, kanye neziteshi ezincane zaphesheya kwezilwandle zihlala endaweni efanayo ye-C5-M njengezindawo zikawoyela negesi, kodwa kunezidingo ezimbili ezengeziwe: izimpahla azinawo abanikazi, ngakho amafasitela okulungisa amafushane futhi ayabiza, kanti izintambo - izintambo ze-medium-voltage array, izifunda zokuthumela amandla, kanye nezinhlelo zokulawula kanye ne-SCADA - kumele zihlale zithembekile empilweni yokuklama ye-turbine ngaphandle kokungenelela okuvamile.
Umphumela wencazelo uwukukhetha okunamandla kokusekelwa kwekhebula lensimbi engagqwali ezindaweni ze-nacelle kanye nezingcezu zokushintsha, kanye nezinhlelo ze-hot-dip galvanized ezamukelwayo ezindaweni ezingavezwanga kakhulu, kanye nokuphathwa kwekhebula okugcina ama-conductor ehlelekile ngaphakathi kwe-tower tower esindayo. Njengoba amapulazi omoya eqhubekela phambili ogwini lolwandle futhi eba amafomethi amakhulu, abaqhubi basebenzisa imininingwane yokusekelwa kwekhebula le-oyili negesi emkhakheni owawubolekwe ngaphambilini umkhuba wasogwini lolwandle - abahlinzeki be-shift babukele eduze.
Izindawo zokupaka imikhumbi, amachweba, kanye nezindawo zokuthenga ezisogwini
Akuzona zonke izindawo zobunjiniyela basolwandle ezintantayo. Izakhiwo zemikhumbi zakha futhi zilungisa imikhumbi ngaphansi kwezimo ezivulekile zogu lolwandle; amachweba asebenzisa imishini yokuphakamisa izinto ezisindayo, izinhlelo zokuphatha izitsha, kanye nokufakwa kwamandla ogu lolwandle emoyeni ogcwele usawoti; izitshalo zokususa usawoti kanye nezindawo zokucubungula ogu lolwandle zisebenzisa amamitha ezinhlelo zikagesi eziqhubekayo ukusuka olwandle. Lezi zindawo zokufaka eziqinile ogu lolwandle zabelana ngohlelo lokugqwala kogu lolwandle ngaphandle kwesabelomali sezinto zangaphandle zogu lolwandle, okwenza kube yimakethe enkulu kunazo zonke yezinhlelo ze-hot-dip galvanized.
Kuma-crane e-gantry e-shipyard, ama-crane e-quay, kanye namaphrojekthi kagesi echwebeni,Ithreyi yekhebula le-HDGkanye nezinhlelo zezitebhisi ngokwe-EN ISO 1461 ziletha impilo yesevisi edingekayo ngengxenyana yezindleko ze-stainless — uma nje i-coating iwugqinsi ngokwanele, i-fittings ine-coating specification efanayo nezingxenye eziqondile, futhi iziphetho ezisikiwe ensimini ziphathwa nge-zinc-rich repair coating. Ukuhlinzekwa komthombo owodwa kubalulekile lapha: lapho ama-couplers, i-fittings, kanye nezisekelo zivela emgqeni ofanayo wokukhiqiza njengethreyi, ikhwalithi ye-coating iyafana kulo lonke uhambo, futhi amaphuzu abuthakathaka avela ezindaweni ezihlanganisiwe zabathengisi ayanyamalala.
Ukukhetha izinto ezifanele kanye nokuqeda
Kwabonjiniyela abacacisa ukwesekwa kwekhebula kunoma iyiphi indawo yasolwandle, isiqondiso sikaQinkai sincipha sibe yizinqumo ezine:
Qondanisa ibanga nendawo yokuchayeka. Gcina insimbi engagqwali yohlobo lwe-316 ezindaweni zokuchayeka, izindawo zokucubungula, kanye nezimpahla ezingenamuntu lapho ukulungiswa kunzima khona; sebenzisa insimbi egayiwe eshisayo ngokwe-EN ISO 1461 noma i-ASTM A123 ezindaweni zasogwini nasemkhathini; gcina izinhlelo ezigayiwe nge-electro-galvanized kanye nezipendiwe zingangeni ngokuphelele ezidingweni zasolwandle.
Cabanga ngokugqwala kwe-galvanic. Lapho insimbi engagqwali kanye ne-aluminium, noma insimbi engagqwali kanye ne-carbon, kuxhunywe endaweni egcwele usawoti, ukugqwala kwe-bimetallic kungabhubhisa insimbi engagqwali kakhulu. Cacisa izinto ezihambisanayo noma ukuhlukaniswa okufakwe umswakama kuzo zonke izixhumi, kufaka phakathi izikhonkwane nama-bracket.
Vikela konke ukunqunywa nokuklwebheka. Iziphetho ezisikiwe ensimini kanye nemigodi ebholiwe yilapho kuqala khona ukugqwala kolwandle. Ukuvikelwa kwe-cathodic kwe-HDG kuvikela insimbi kulezi zindawo, futhi ukugqoka kokulungisa okucebile nge-zinc kufanele kusetshenziswe noma yikuphi lapho ukugqoka konakaliswe khona endaweni.
Funa amadokhumenti. Amathebula okulayisha, imibiko yobukhulu be-coating, kanye nezitifiketi zezinto ezibonakalayo umehluko phakathi kwesistimu ecacisiwe kanye ne-gamble. Kumaphrojekthi asemanzini, umbiko we-coating uhlolwa ngokucophelela njengethreyi yekhebula uqobo.
Izindinganiso ezilawula ukwesekwa kwekhebula lasolwandle
Uhlaka lwezindinganiso zokucaciswa kwethreyi yekhebula yasolwandle kanye neyasogwini luhambisana kuzo zonke izindawo: I-IEC 61537 ihlanganisa izidingo zokuhlola nokumaka zethreyi yekhebula kanye nezinhlelo zeladi; I-EN ISO 1461 kanye ne-ASTM A123 zilawula izembozo ezishisayo ezifakwe elangeni; I-ISO 12944 ichaza izigaba zokugqwala eziqhuba ukukhethwa kwezinto; I-NEMA VE 1 kanye ne-VE 2 zisekela umkhuba waseNyakatho Melika; kanye nemithetho yenhlangano yokuhlela ingeza ungqimba olwengeziwe lwemikhumbi kanye nezindawo ezintantayo. Amaphrojekthi adinga kakhulu ukuthi konke okungenhla kubhalwe phansi ngokuthunyelwa ngakunye - ibha ehlunga abahlinzeki abangakwazi ukukhiqiza idatha yomthwalo esekelwa ukuhlolwa.
Ukuhlolwa kokuthengwa kwempahla
Iphethini kuzo zonke izingxenye zasolwandle iyafana: imininingwane inqunywa onjiniyela bokugqwala kanye nabanikazi bezimpahla ngaphambi kokuba kuqokwe usonkontileka kagesi, futhi abahlinzeki abawinayo yilabo abangabhala phansi izinga lezinto ezibonakalayo, ukusebenza kokumboza, kanye nesilinganiso somthwalo ngaphandle kokungabaza. “Ithreyi yekhebula lasolwandle ithengwa kanye futhi ihlolwe amashumi eminyaka,” kusho inkampani. “Sakha eyethu ukuze ukuhlolwa ngakunye kuthole into efanayo: uhlelo olubhalwe phansi, olwenza lokho kanye okuthembisiwe.”
