Ukwanda kweziseko zophuhliso zaselwandle kwiminyaka yoo-2020 kulula ukukubona ukusuka kumlambo: iikhreyini ezintsha ze-quay ziphakama ngaphezu kwezikhululo zeekhonteyina, iindawo eziphezulu zesitishi esingaphantsi kolwandle ziphuma kwiiyadi zokwenziwa, iibhleyidi ze-turbine ezifakwe kwiindawo zokubeka izinto. Okungabonakaliyo kumlambo yinkqubo yombane eyenza zonke ezi zinto zisebenze - kunye neemayile zeitreyi yentambokwayeileli yentamboezithwala amandla azo, ulawulo kunye neesekethe zezixhobo ngomoya ogcwele ityuwa.
Amanani achaza isizathu sokuba loo maleko ungabonakaliyo ngoku ubaluleke ngakumbi kunangaphambili. Imarike yehlabathi yomoya ophuma elunxwemeni yayixabisa i-USD 42.3 yeebhiliyoni ngo-2025 kwaye kulindeleke ukuba ikhule ukusuka kwi-USD 45.2 yeebhiliyoni ngo-2026 ukuya kwi-USD 93.5 yeebhiliyoni ngo-2033, i-CAGR ye-10.9 yepesenti, ngokutsho kweGrand View Research. Imarike yombane wezibuko imiselwe ukukhula ukusuka kwi-USD 3.1 yeebhiliyoni ngo-2026 ukuya kwi-USD 4.64 yeebhiliyoni ngo-2030 kwi-CAGR ye-10.6 yepesenti, kwaye amandla olwandle - iinkqubo ezivumela iinqanawa ukuba zicime iinjini zazo zedizili - kulindeleke ukuba zinyuke ukusuka kwi-USD 1.57 yeebhiliyoni ukuya kwi-USD 2.75 yeebhiliyoni ngo-2033. I-RenewableUK iqikelela malunga ne-236 GW yomoya ophuma elunxwemeni osebenza ngokupheleleyo ekupheleni kuka-2030.
Zonke ezo dola ziphelela, ngokuyinxenye, kwinkqubo yokusasazwa kombane echazwe kwiimeko zomoya eziqatha kakhulu kwindawo eyakhiweyo. Itreyi yekhebula yintsika ezolileyo yaloo nkqubo.
Kutheni iziseko zophuhliso zaselwandle zithatha inkxaso yekhebula njengento ebalulekileyo
Uluntu lobunjineli lufunde kudala ukuba iindawo ezikunxweme nolwandle zizinto ezahlukeneyo ezichazwe yindalo yonke. Iimozulu zaselwandle zikwinqanaba eliphezulu le-ISO 12944 corrosivity scale — C5-M kwiindawo ezikunxweme nolwandle ezinetyuwa eninzi — apho ityuwa esemoyeni, ukumanzisa nge-cyclic kunye noxinzelelo lwe-chloride zihlasela intsimbi engakhuselekanga ngokukhawuleza kakhulu kunayo nayiphi na into engcolisayo ngaphakathi. Kubanini beziseko zophuhliso abanempahla yabo ephila iminyaka engama-25 yoyilo, oku kutshintsha inkxaso yekhebula ukusuka kwinto yomgca wempahla ibe sisigqibo sesicwangciso sokugqwala esineziphumo ezibhaliweyo.
Umaleko olawulayo uyawuqinisa. I-IEC 61537 ilawula iimfuno zovavanyo kunye nokumakishwa kwetreyi yekhebula kunye neenkqubo zeleli, i-EN ISO 1461 kunye ne-ASTM A123 zichazaingubo eshushu egqunyiweyoIinkampani zokusebenza, kunye nokuhlelwa kweendawo ezifana ne-DNV, i-ABS kunye ne-Lloyd's Register zisebenzisa imithetho yazo ekufakweni kwezinto ezidadayo nezithwalwa yinqanawa. Ngokuya kusanda, iiprojekthi zeziseko zophuhliso zaselwandle zifuna ukuba zonke ezi zinto zibonakaliswe ngokuthunyelwa ngakunye: izatifikethi zezinto, iingxelo zobukhulu be-coating kunye neetafile zomthwalo ezipapashiweyo zifika nezinto, kungekhona emva kwazo.
Ukufakelwa kombane kwizibuko: umngeni wokulungiswa kwakhona
Amazibuko kulapho ubunzima bombane beziseko zolwandle bukhula ngokukhawuleza. Izitishi zeekhonteyina zifakela umbane kwiikhreyini zazo zeegantry kunye nezixhobo zerabha, iindawo zeekhonteyina ezifrijiweyo zitsala umbane ongaphezulu kunangaphambili, kwaye ukufakelwa kombane elunxwemeni kudibanisa iinqanawa ezibekwe emkhombeni - iinqanawa zohambo, abathwali beekhonteyina kunye neebhuleki - kumbane wegridi. Iinkqubo zeziseko zophuhliso zezibuko ze-US Federal Maritime Administration, umjikelo wotyalo-mali lwaselwandle eYurophu kunye namazibuko eehabhu akhulayo aseAsia zonke zityhalela kwicala elifanayo: ukufakelwa kombane ngobukhulu, kwiindawo ezingazange zenzelwe oko.
Inyani yokulungiswa kweentambo yenza ulawulo lweentambo lube yindlela ebalulekileyo. Iiterminal ezikhoyo zithutha ii-feeders ezintsha ze-medium-voltage, ii-transformer feeds kunye neenethiwekhi zolawulo kwiindlela ezixineneyo - phantsi kwee-quays, ecaleni kwemiphetho ye-wharf, ngokusebenzisa ulwandiso lwesitishi esincinci - apho iinkqubo zeentambo zentambo kufuneka zixhonywe ngaphezulu kwe-salt spray, kwiindawo ezinamanzi kunye nakwii-crane gantries ezixineneyo. Iinkqubo zeentambo ze-galvanized kunye neetreyi ezishushu ngokwe-EN ISO 1461 zilawula eli candelo: zibonelela ngobomi benkonzo obufunekayo ngexabiso elincinci lentsimbi engagqwaliyo, ukuba nje izixhobo ziphethe iinkcukacha ezifanayo zokugquma njengoko amacandelo athe tye kunye neziphelo ezisikiweyo zifumana unyango lokulungisa olucebile yi-zinc. Ubonelelo lomthombo omnye lubalulekile apha, kuba ukuthengiswa komthengisi oxutyiweyo onomgangatho wokugquma ongaguqukiyo kuyasilela kuqala kwiindawo zayo zokunxibelelanisa.
Umoya ongaphandle kolwandle: iinkcukacha ezibolekwe kwioyile negesi
Umoya ophuma elwandle uyandisa imithetho efanayo elwandle, apho izinto ezisetyenziswayo zingabi namntu kwaye iifestile zolondolozo zilinganiswa kwiifestile zemozulu endaweni yeentsuku zomsebenzi. Ukufakelwa kwe-fixed-bottom - ii-monopiles, iijakethi kunye nezakhiwo ezisekwe kumxhuzulane - zibambe i-74.4 yepesenti yemarike ngo-2025, kwaye i-turbine nganye, isiqwenga sotshintsho kunye nesitishi esingaphantsi kolwandle siphethe iphakheji epheleleyo yombane: iintambo ze-medium-voltage array, iisekethe zokuthumela umbane ngaphandle, ulawulo kunye neenkqubo ze-SCADA.
Ngaphakathi kwi-nacelle okanye kwisikhululo esingaphantsi kolwandle, inkxaso yekhebula kufuneka ihlale iphila ngokungcangcazela okuqhubekayo, umzila ovalekileyo kunye nomoya ofanayo we-C5-M njengeqonga leoyile negesi. Yiyo loo nto iinkcukacha zomzi-mveliso zidibene kwindlela yokusebenza ye-oyile negesi: inkxaso yekhebula yentsimbi engagqwaliyo kwiindawo ze-nacelle, iziqwenga zotshintsho kunye neendawo zesikhululo apho kunzima ukufikelela khona, iinkqubo ze-hot-dip galvanized kwiindawo ezingatyhilekanga kangako, kunye noluhlu olupheleleyo, oluneenkcukacha zokufakelwa ukuze iindlela zifakelwe kwaye zilungiswe ngaphandle kokwenziwa okukhethekileyo kude nolwandle. Njengoko iifama zomoya zingena emanzini anzulu kunye namaqonga adadayo angena kwipayipi, abaqhubi basebenzisa la manqanaba ngokuqina okukhulayo - ukuphuculwa okuzolileyo kodwa okuhlala kusenzeka kwinqanaba lolawulo lwekhebula lweli candelo.
Amandla aselunxwemeni kunye nezakhiwo zoshishino
Phakathi kwezinto ezidadayo nezizinzileyo kukho izityalo zaselunxwemeni ezisebenza ngoqoqosho lwamandla: ii-terminals ezifumana i-LNG, izityalo zokukhupha ityuwa emanzini, izitishi zamandla zaselunxwemeni kunye neendawo zokwenza nokulawula ezakha iinqanawa zaselunxwemeni ngokwazo. Ezi zibonelelo zisebenzisa iinkqubo zombane eziqhubekayo eziziimitha ukusuka elwandle, phantsi kolawulo olufanayo lokugqwala njengeempahla zaselunxwemeni kodwa ngaphandle kohlahlo-lwabiwo mali lwaselunxwemeni lwezinto zangaphandle. Zezona marike zinkulu zeenkqubo ze-hot-dip galvanized, kwaye zibeka ixabiso eliphakamileyo kwikhono elinye lobunjineli: ukuqikelelwa kwangaphambili. Xa ikontrakta ye-EPC yesitishi se-LNG icacisa itreyi yekhebula, ithenga ukusebenza komthwalo obhaliweyo, ukugquma okufanayo kunye noluhlu lwezixhobo ezivala inkqubo - kuba ukusebenza komthombo omnye, okubhalwe ngokupheleleyo yikona okugcina ishedyuli yokwakha iqikelelwa kwimeko apho imozulu sele inekhalenda.
Utshintsho lokuthenga: ukuthenga inkqubo, hayi icandelo
Kuzo zonke iindawo zophuhliso lweziseko zolwandle, ipatheni iyafana:itreyi yentamboayisathengwa njengento yomgca ocingelwayo emva koko. Abakhi be-EPC kunye nabanini beeasethi bachaza iinkqubo ezipheleleyo - amacandelo athe tye, izixhobo, inkxaso kunye namaxwebhu avela kumenzi omnye - kuba ixabiso lokungaphumeleli kweenkcukacha kwindawo yaselwandle lilinganiswa ngamashumi eminyaka, kungekhona ngeedola. Abavelisi abalawula ukukhupha, ukwenziwa, ukugaya kunye nokuvavanya ngaphakathi, kunye neetafile zomthwalo kunye neengxelo zokugquma ngenqanawa kunye ne-odolo nganye, bayaphumelela kwiimfazwe zeenkcukacha ngokuchasene nababoneleli abanikezela ngemveliso engahlukaniyo.
IShanghai Qinkai Industrial, umenzi we-NEMA-standard tray, ladder, i-seismic support kunye neenkqubo ze-stainless steel, uthi abathengi beziseko zolwandle ngoku bacela ukuqinisekiswa kobukhulu be-coating kunye nokulandeleka kwezinto kwisigaba se-RFQ - ngaphambi kokuba ixabiso lixoxwe. "Kwiziseko zolwandle, inkqubo yenkxaso yekhebula ichazwa kube kanye kwaye ihlolwe ubomi bempahla," utshilo inkampani. "Ababoneleli abaphumelelayo ngabo banemibhalo enganyangekiyo nokugqwala njengemveliso yabo."
Imbono evela kwishedyuli yokwakha
Kwabakhi kunye nabanini beeprojekthi, umyalezo osebenzayo ulula: kwiziseko zophuhliso zaselwandle,ulawulo lweentamboibaluleke kakhulu kwishedyuli. Ukulungiswa kombane kwizibuko, iipakeji zombane zomoya olwandle kunye nokwandiswa kwezityalo zaselunxwemeni zonke zihamba ngokulandelelana okufanayo - uyilo, ukuthengwa, ukufakwa, ukufakelwa amandla - kwaye inkqubo yokuxhasa ikhebula iphakathi kwayo. Ukuyichaza kwangethuba, ngomgangatho wezinto ezifanelekileyo, uluhlu olupheleleyo lokufakelwa kunye namaxwebhu apheleleyo, ayisiyonto yobunjineli. Ngumahluko phakathi kweprojekthi enika amandla ngexesha kunye neyo ifumanisa icebo layo lokugqwala kuhlolo lokuqala.
Ukwanda kweziseko zophuhliso lolwandle kuza kulinganiswa ngeegigawatts, ii-berths kunye nee-terminals. Ngaphantsi kwayo yonke, imayile ngemayile, kukho itreyi yekhebula ethwala umsinga - eyenzelwe ityuwa, ebhalwe phantsi amashumi eminyaka, kwaye ekugqibeleni ifumana ingqalelo eyifaneleyo indima yayo.
