Ukuchuma kwengqalasizinda yasolwandle ngawo-2020 kulula ukukubona kusukela emzileni wamanzi: ama-crane amasha e-quay akhuphuka ngaphezu kwezikhungo zezitsha, iziteshi ezingaphansi kolwandle eziphuma emagcekeni okukhiqiza, ama-turbine blades abekwe emachwebeni okubeka. Okungabonakali kusukela emzileni wamanzi uhlelo lukagesi olwenza zonke lezi zimpahla zisebenze - kanye namamayelaithreyi yekhebulafuthiileli yekhebulaezithwala amandla azo, ukulawula kanye nezinhlelo zokusebenza emoyeni ogcwele usawoti.
Izinombolo zichaza ukuthi kungani leso sigaba esingabonakali manje sibaluleke kakhulu kunanini ngaphambili. Imakethe yomhlaba wonke yomoya olwandle yayinenani lama-USD 42.3 billion ngo-2025 futhi kulindeleke ukuthi ikhule isuka kuma-USD 45.2 billion ngo-2026 iye kuma-USD 93.5 billion ngo-2033, okuyi-CAGR engu-10.9%, ngokusho kwe-Grand View Research. Imakethe kagesi echwebeni izokhula isuka kuma-USD 3.1 billion ngo-2026 iye kuma-USD 4.64 billion ngo-2030 ku-CAGR engu-10.6%, kanti amandla olwandle - izinhlelo ezivumela imikhumbi ukuthi ivale izinjini zayo zedizili - kulindeleke ukuthi ikhuphuke isuka kuma-USD 1.57 billion iye kuma-USD 2.75 billion ngo-2033. I-RenewableUK ilinganisela cishe ama-GW angu-236 omoya olwandle osebenza ngokugcwele ekupheleni kuka-2030.
Yonke yaleyo mali iphelela, ngokwengxenye, ohlelweni lokusabalalisa ugesi oluchazwe ngezimo zomkhathi ezinzima kakhulu endaweni eyakhiwe. Ithreyi yekhebula iyinsika ethule yalolo hlelo.
Kungani ingqalasizinda yasolwandle ibheka ukwesekwa kwekhebula njengento ebalulekile
Umphakathi wobunjiniyela wafunda kudala ukuthi izindawo zasogwini kanye nezasogwini ziyindawo ehlukile yokuchaza. Izimo zasolwandle ziphezulu esikalini sokugqwala se-ISO 12944 — i-C5-M yezindawo zasogwini kanye nezasogwini ezinosawoti omningi — lapho usawoti ohamba emoyeni, ukumanzisa okujikeleza kanye nokucindezeleka kwe-chloride kuhlasela insimbi engavikelwe ngokushesha kakhulu kunanoma yikuphi ukungcola okungaphakathi ezweni. Kubanikazi bengqalasizinda abanezimpahla zabo eziphila iminyaka engu-25 yokuklama, lokhu kushintsha ukwesekwa kwekhebula kusuka entweni yomugqa wezimpahla kube yisinqumo sesu lokugqwala esinemiphumela ebhaliwe.
Isendlalelo sokulawula siyasiqinisa. I-IEC 61537 ilawula izidingo zokuhlola nokumaka zethreyi yekhebula kanye nezinhlelo zeladi, i-EN ISO 1461 kanye ne-ASTM A123 zichazaisembozo esishisiwe esishisayoIzinhlangano zokusebenza, kanye nokuhlela njenge-DNV, i-ABS kanye ne-Lloyd's Register zisebenzisa imithetho yazo ekufakweni okuntantayo kanye nokuthwalwa yimikhumbi. Ngokwandayo, amaphrojekthi engqalasizinda yasolwandle adinga ukuthi konke lokhu kufakazelwe ngokuthunyelwa ngakunye: izitifiketi zezinto, imibiko yobukhulu bokumboza kanye namathebula omthwalo ashicilelwe afika nezinto, hhayi ngemva kwazo.
Ukufakwa kukagesi echwebeni: inselele yokulungiswa kabusha
Amachweba yilapho ubunzima bengqalasizinda kagesi yasolwandle bukhula khona ngokushesha. Ama-terminal e-container afaka ugesi kuma-gantry cranes awo kanye nemishini enamathayi enjoloba, izindawo ze-container eziqandisiwe zidonsa amandla amaningi kunanini ngaphambili, kanti ukufakwa kwamandla ogwini kuxhuma imikhumbi ebiyelwe - imikhumbi yokuhamba ngesikebhe, abathwali be-container kanye nama-bulker - kugesi wegridi. Izinhlelo zengqalasizinda ye-port ze-US Federal Maritime Administration, umjikelezo wokutshalwa kwezimali zasolwandle eYurophu kanye namachweba e-hub akhula e-Asia konke kusunduza ohlangothini olufanayo: ukufakwa kukagesi ngezinga, ezindaweni ezingakaze zenzelwe lokho.
Iqiniso lokulungiswa kabusha lenza ukuphathwa kwekhebula kube yindlela ebalulekile. Ama-terminal akhona adlulisa ama-feeder amasha e-medium-voltage, ama-feed e-transformer kanye namanethiwekhi okulawula ngokusebenzisa imigwaqo eminyene - ngaphansi kwama-quay, emaphethelweni echweba, ngokusebenzisa izandiso zesiteshi esincane - lapho izinhlelo ze-cable ladder kumele zilengiswe ngaphezu kwe-salt spray, ezindaweni zokudonsa amanzi kanye nasezindaweni zokugaya i-crane ezisindayo. Izinhlelo ze-hot-dip galvanized ladder kanye ne-tray ngokwe-EN ISO 1461 zibusa kulesi sigaba: ziletha impilo yesevisi edingekayo ngengxenyana yezindleko zensimbi engagqwali, uma nje izinsimbi zinencazelo efanayo ye-coating njengoba izingxenye eziqondile kanye neziphetho ezisikiwe ensimini zithola ukwelashwa kokulungiswa okucebile nge-zinc. Ukunikezwa komthombo owodwa kubaluleke kakhulu lapha, ngoba ukuthengiswa okuxubile okunekhwalithi ye-coating engaguquki kwehluleka kuqala ezindaweni zayo zokuxhuma.
Umoya ongaphandle kolwandle: imininingwane ebolekwe ku-oyili negesi
Umoya ogwini lolwandle welula imithetho efanayo ogwini lolwandle, lapho izimpahla zingabi namuntu futhi amafasitela okulungisa alinganiswa ngamafasitela esimo sezulu kunezinsuku zokusebenza. Ukufakwa kwezansi eziqinile - ama-monopile, amajakethi kanye nezakhiwo ezisekelwe ekudonseni amandla - kwakha amaphesenti angu-74.4 emakethe ngo-2025, futhi i-turbine ngayinye, ingxenye yokuguquka kanye nesiteshi esincane ogwini lolwandle siphethe iphakheji ephelele kagesi: izintambo ze-medium-voltage array, amasekethe okuthumela amandla, izinhlelo zokulawula kanye ne-SCADA.
Ngaphakathi kwe-nacelle noma isiteshi esingaphansi kolwandle, ukwesekwa kwekhebula kumele kuqhubeke nokudlidliza okuqhubekayo, umzila ovalekile kanye nomoya ofanayo we-C5-M njengepulatifomu kawoyela negesi. Yingakho incazelo yemboni ihlangene nomkhuba wezinga likawoyela negesi: ukwesekwa kwekhebula lensimbi engagqwali ezindaweni ze-nacelle, izingcezu zokushintsha kanye neziteshi ezingaphansi lapho ukufinyelela kunzima khona, izinhlelo ze-hot-dip galvanized ezindaweni ezingavezwanga kahle, kanye nobubanzi bokufakwa okuphelele, okubhalwe phansi ukuze imizila ikwazi ukufakwa futhi iguqulwe ngaphandle kokwenziwa okukhethekile ogwini. Njengoba amapulazi omoya ethuthela emanzini ajulile kanye namapulatifomu antantayo engena epayipini, abaqhubi basebenzisa la mabanga ngokuqina okwandayo - ukuthuthukiswa okuthule kodwa okuqhubekayo kwesisekelo sokuphathwa kwekhebula lomkhakha.
Izakhiwo zamandla ogwini kanye nezimboni
Phakathi kokuntantayo nokungaguquki kukhona izitshalo zasogwini ezicubungula umnotho wamandla: iziteshi zokwamukela i-LNG, izitshalo zokukhipha usawoti emanzini, iziteshi zamandla zasogwini kanye namayadi okukhiqiza nokuqondisa akha imikhumbi yasogwini uqobo. Lezi zikhungo zisebenzisa amamitha ezinhlelo zikagesi eziqhubekayo ukusuka olwandle, ngaphansi kohlelo olufanayo lokugqwala njengezimpahla zasogwini kodwa ngaphandle kwesabelomali sasogwini sezinto ezingavamile. Ziyimakethe enkulu kunazo zonke yezinhlelo ze-hot-dip galvanized, futhi zibeka intengo ephezulu kumandla obunjiniyela: ukubikezela. Lapho umakhi we-EPC wesiteshi se-LNG ecacisa ithreyi yekhebula, uthenga ukusebenza komthwalo okubhaliwe, ukumbozwa okufanayo kanye nobubanzi bokufakwa okuvala uhlelo - ngoba ukusebenza komthombo owodwa, okubhalwe ngokugcwele yilokho okugcina isheduli yokwakha ibikezela endaweni lapho isimo sezulu sesivele siphethe ikhalenda.
Ushintsho lokuthengwa kwempahla: ukuthenga uhlelo, hhayi ingxenye
Kuzo zonke izingxenye zengqalasizinda zasolwandle, iphethini iyafana:ithreyi yekhebulaayisathengwa njengento yomugqa ocatshangelwe kamuva. Osonkontileka be-EPC kanye nabanikazi bezimpahla bachaza izinhlelo eziphelele - izingxenye eziqondile, ukufakwa, izisekelo kanye nemibhalo evela kumkhiqizi oyedwa - ngoba izindleko zokwehluleka kwemininingwane endaweni yasolwandle zilinganiswa ngamashumi eminyaka, hhayi ngamadola. Abakhiqizi abalawula ukukhipha, ukukhiqiza, ukufaka i-galvanizing kanye nokuhlola ngaphakathi, kanye nokuthi amatafula okulayisha kanye nemibiko yokumboza ngemikhumbi nayo yonke i-oda, banqoba izimpi zemininingwane ngokumelene nabaphakeli abanikeza umkhiqizo ongahlukile.
I-Shanghai Qinkai Industrial, umkhiqizi we-NEMA-standard tray, ladder, support susmic kanye nezinhlelo zensimbi engagqwali, uthi abathengi bengqalasizinda yasolwandle manje bacela ukuqinisekiswa kobukhulu be-coating kanye nokulandelela izinto esiteji se-RFQ - ngaphambi kokuba kuxoxwe ngentengo. "Engqalasizinda yasolwandle, uhlelo lokusekela ikhebula luchazwa kanye futhi luhlolwe impilo yonke yempahla," kusho inkampani. "Abaphakeli abachumayo yilabo abanemibhalo evikela ukugqwala njengomkhiqizo wabo."
Umbono osuka ohlelweni lokwakha
Kwabakhi benkontileka kanye nabanikazi bamaphrojekthi, umyalezo owusizo ulula: engqalasizinda yasolwandle,ukuphathwa kwekhebulakubalulekile kakhulu ngesikhathi. Ukulungiswa kukagesi emachwebeni, amaphakheji kagesi omoya asogwini kanye nokwandiswa kwezitshalo zasogwini konke kuhamba ngokulandelana okufanayo - ukuklama, ukuthengwa, ukufakwa, ukunikezwa kwamandla - kanye nohlelo lokusekela ikhebula luphakathi kwalo. Ukuyichaza kusenesikhathi, ngebanga lezinto ezifanele, ububanzi bokufakwa okuphelele kanye nemibhalo ephelele, akuyona into enhle yobunjiniyela. Umehluko phakathi kwephrojekthi enika amandla ngesikhathi kanye naleyo ethola isu layo lokugqwala ekuhlolweni kokuqala.
Ukwanda kwengqalasizinda yasolwandle kuzolinganiswa ngama-gigawatts, izindawo zokubeka imikhumbi kanye nezindawo zokugcina. Ngaphansi kwakho konke, imayela ngemayela, kunethreyi yekhebula ethwala ugesi - eyenzelwe usawoti, ebhalwe phansi amashumi eminyaka, futhi ekugcineni ithola ukunakwa okufanele indima yayo.
