Ngati muwona sitima yaikulu ikuyandama panyanja, ikukhala pamalo omwewo kwa zaka zambiri, ndi sitima zonyamula mafuta nthawi zonse zikubwera pafupi "kudzanyamula katundu" - mwina si sitima yonyamula katundu. Ndi FPSO.
01 Kodi FPSO ndi chiyani?
FPSO imayimira Floating Production Storage and Offloading. Mwachidule, ndi fakitale yamafuta ndi gasi yoyandama panyanja.
Ikuoneka ngati sitima yapamadzi, koma kwenikweni ndi fakitale yoyandama yomwe imatha kukonza mafuta osakonzedwa, kuisunga, ndikuyitsitsa ku sitima zapamadzi. FPSO ndiye maziko a chitukuko cha mafuta ndi gasi padziko lonse lapansi, yomwe imayika ndalama zoposa 80% ya ndalama zonse zomwe zimayikidwa mumakina opangira zinthu zoyandama. Ntchito zake zazikulu zalembedwa m'dzina lake:
Kupanga- Kulekanitsa mafuta, gasi, madzi, ndi mchenga kuchokera ku zitsime kudzera mu ma compressor, olekanitsa, ndi machitidwe ochizira. FPSO yayikulu imatha kukonza migolo 150,000 mpaka 200,000 ya mafuta osakonzedwa patsiku - zofanana ndi fakitale yaying'ono yoyeretsera mafuta m'mphepete mwa nyanja.
Malo Osungirako– Minda yambiri yamadzi akuya ili kutali ndi gombe. Kupanga mapaipi akutali n’kokwera mtengo komanso kumatenga nthawi. FPSO imathetsa vutoli mwa kusunga mafuta osakonzedwa bwino m’thupi mwake. Matani ambiri a FPSO olemera kwambiri ndi kuyambira matani 100,000 mpaka 300,000, okhala ndi mphamvu yosungira migolo 700,000 mpaka 2 miliyoni.
Kutsitsa– Kudzera m'mapaipi oyandama kapena kutsitsa zida, mafuta osakonzedwa amasamutsidwa kupita ku sitima zonyamula mafuta kuti azinyamulidwa kupita kugombe. FPSO nthawi zambiri imatsitsa mafuta kawiri mpaka kanayi pa sabata.
02 Kuyenda kwa Mafuta ndi Gasi: Kodi FPSO Ikugwirizana Bwanji?
Mu pulojekiti yeniyeni yopangira mafuta ndi gasi m'mphepete mwa nyanja, FPSO ndi gawo limodzi chabe la dongosolo lalikulu kwambiri. Malo asanasinthe chuma cha pansi pa nyanja kukhala ndalama zokhazikika, mizere itatu ikuluikulu iyenera kugwira ntchito limodzi: zitsime, machitidwe a pansi pa nyanja, ndi malo opangira zinthu pamwamba.
Zipangizo zobowolera kapena zobowolera zimabowola zitsime ndikubweretsa mafuta ndi gasi pamwamba. Mitengo ya Khirisimasi ya pansi pa nyanja imayang'anira kuyenda kwa chitsime. Mapaipi a pansi pa nyanja amanyamula chisakanizo chopangidwacho kupita ku FPSO. Kenako FPSO imayang'anira kukonza, kusunga, ndi kutsitsa.
Gawo Loyamba: Kutulutsa ndi Kusamutsa
Chomwe chimatuluka m'chitsime cha pansi pa nyanja si mafuta enieni. Ndi chisakanizo cha mafuta, gasi, madzi, ndi mchenga. Chisakanizochi chimayenda kudzera m'mapaipi a pansi pa nyanja kapena zokwezera ku FPSO. Zokwezera zomwe zimalumikiza pansi pa nyanja ndi FPSO ndi "mitsempha" ya dongosololi. Ziyenera kupirira kuthamanga kwambiri, dzimbiri, komanso nyengo yovuta ya nyanja. Ichi ndichifukwa chake machitidwe a pansi pa nyanja nthawi zambiri amakhala gwero la kuchedwa kwa ntchito komanso kukwera mtengo.
Gawo Lachiwiri: Kukonza FPSO - Ntchito Yaikulu
FPSO imawoneka ngati sitima kunja, koma mkati mwake muli pafupi ndi fakitale yoyandama. Denga lili ndi ma module okonzera zinthu omwe amafanana ndi fakitale yaying'ono yoyeretsera:
l Olekanitsakugwiritsa ntchito mphamvu yokoka kuti alekanitse mafuta, gasi, ndi madzi
l Magawo okhazikika a mafuta osakonzedwaChotsani zinthu zowunikira kuti mupewe kutaya kwa nthunzi panthawi yosungira ndi kunyamula
l Machitidwe ochizira mpweyaMpweya wothira madzi m'thupi ungagwiritsidwe ntchito popanga magetsi kapena kuubwezeretsanso m'malo osungiramo madzi.
l Machitidwe oyeretsera madziSambitsani madzi opangidwa kuti muwabwezeretse kapena kuwatulutsa (malamulo okhudza chilengedwe akukhwima kwambiri)
Akangokonzedwa, mafuta osakonzedwa bwino amasungidwa m'matanki a FPSO.
Gawo Lachitatu: Kutsitsa
Mafuta osakonzedwa akafika pamlingo winawake, sitima yonyamula mafuta imaima pafupi ndi FPSO. Mapaipi oyandama amasamutsa mafutawo kupita ku sitimayo, yomwe kenako imapita nawo ku mafakitale oyeretsera mafuta m'mphepete mwa nyanja. Kupanga sikumatha mpaka mafutawo atagulitsidwa - kuthekera kotsitsa mafuta ndiye njira yomaliza yopezera malonda.
Mtengo Waukulu wa FPSO
FPSO imathetsa vuto lalikulu: imapangitsa kuti minda yamadzi akuya ikhale yopindulitsa pazachuma. M'madzi osaya, mutha kuyika mapaipi kugombe. Koma m'madzi akuya opitilira mamita 1,000, kuyika mapaipi mazana ambiri ndi okwera mtengo kwambiri komanso kovuta mwaukadaulo. FPSO imakulolani kukonza, kusunga, ndikutsitsa pansi pa nthaka - kusandutsa malo osungira madzi akuya "osakonzedwa" kukhala chuma chopindulitsa.
03 FPSO, FPU, FLNG, FSRU: Kodi Kusiyana N'chiyani?
Ma chidule anayi awa nthawi zambiri amakambidwa pamodzi, koma amagwira ntchito zosiyanasiyana. FPSO imagwira ntchito ndi mafuta osakonzedwa (Mafuta). FLNG imagwira ntchito ndi kusungunuka kwa gasi wachilengedwe (Gasi) ndi kutulutsa ndi kutumiza kunja. FSRU imagwira ntchito ndi kulandira ndi kubwezeretsanso gasi wachilengedwe (Gasi). FPU imangogwira ntchito - siisunga.
FPSO (Kusungirako ndi Kutsitsa Zopanga Zoyandama):"Fakitale yoyeretsera mafuta yoyandama" m'minda ya mafuta ya m'madzi akuya. Imakonza mafuta osakonzedwa, kusungira, ndikutsitsa ku matanki.
FPU (Chigawo Chopanga Choyandama):Pulatifomu yopangira yokha. Imalekanitsa mafuta, gasi, ndi madzi, koma ilibe malo osungira. Mafuta ndi gasi okonzedwa ayenera kutumizidwa nthawi yomweyo kudzera m'mapaipi. Nthawi zambiri amagwiritsidwa ntchito m'minda yomwe ili ndi maukonde a mapaipi omwe alipo.
FLNG (Gasi Wachilengedwe Wosungunuka Woyandama):Malo oyeretsera mpweya wachilengedwe omwe amayandama. Amaima pamwamba pa malo oyeretsera mpweya, amayeretsa ndi kusungunula mpweya wotulutsidwa, amausunga, ndikutsitsa ku zonyamulira za LNG. Amachotsa kufunikira kwa malo oyeretsera mpweya m'mphepete mwa nyanja ndi mapaipi a gasi akutali.
FSRU (Chigawo Chosungira ndi Kukonzanso Zoyandama):Malo olandirira magetsi a LNG. Magalimoto onyamula magetsi a LNG amabweretsa mpweya wachilengedwe wosungunuka ku FSRU, womwe umasunga mpweyawo ndikuubwezeretsanso kukhala mpweya wokwanira kuti ugwiritsidwe ntchito pa mapaipi. Umapereka nthawi yochepa yomanga komanso kusinthasintha kwakukulu.
04 Kodi FPSO Imakhazikika Bwanji? Dongosolo Lolumikizira Malo Amodzi
FPSO iyenera kukhala pamalo enaake kwa zaka zambiri. Siingathe kusuntha. Izi zimachitika kudzera mu makina omangira. Chifukwa chakuti zokweza zimakhala ndi kusinthasintha kochepa, kuyenda kwa FPSO nakonso kumakhala kocheperako.
Makina omangira matayala amagawidwa m'magulu awiri akuluakulu:
Malo Osungira Zinthu Ambiri
Ma nangula angapo amateteza FPSO kuchokera ku bow ndi stern. Malo olowera sitimayo ndi okhazikika. Dongosololi ndi losavuta komanso lotsika mtengo, koma limakhudzidwa kwambiri ndi mphepo ndi mafunde am'deralo. Ndi loyenera kokha pa malo ofatsa a panyanja, monga omwe ali kumadzulo kwa Africa.
Malo Osungira Zinthu Pamodzi (SPM)
Iyi ndi njira yodziwika bwino yomangira ma FPSO, yomwe imagwiritsidwa ntchito ndi pafupifupi 80% ya zombo zapadziko lonse lapansi. Mfundo yaikulu ndi yosavuta: FPSO imazungulira madigiri 360 mozungulira malo okhazikika pansi pa madzi (turret). Imagwira ntchito ngati chotchingira nyengo, nthawi zonse imagwirizana ndi mphepo ndi mafunde kuti ichepetse mphamvu. Izi zimapangitsa kuti ikhale yoyenera nyengo zovuta za panyanja.
Mitundu itatu ikuluikulu ya maulumikizidwe a SPM ndi awa:
Mtundu wa Buoy:Booy yokhazikika m'mphepete mwa nyanja imagwira ntchito ngati malo omangira sitima komanso malo olumikizirana pakati pa sitima zapamadzi za pansi pa nyanja ndi sitimayo. Imasamutsa mafuta, gasi, ndi zakumwa pakati pa makina apansi pa nyanja ndi sitima yapamadzi yomangira sitimayo.
Mtundu wa mphamvu:Nyumba yolimba ya nsanja yolumikizidwa pansi pa nyanja imagwira ntchito ngati nangula wokhazikika. Manja ofewa a goli amalumikiza nsanjayo ndi FPSO. Izi ndizoyenera kuya kwa madzi osaya kwambiri mpaka apakati.
Mtundu wa Turret:Amagwiritsidwa ntchito ndi ma FPSO opitilira 70% padziko lonse lapansi. Mpandawu umaphatikiza malo omangira, kusamutsa madzi, ndi kutumiza mphamvu/hydraulic. Mpandawu wamkati umayikidwa mkati mwa chombocho. Mpandawu wakunja umayikidwa kutsogolo ndipo ndi wofala kwambiri pa sitima zoyendera mafuta zosinthidwa.
Dongosolo lolumikizira malo amodzi lili ndi ntchito ziwiri zofunika kwambiri. Choyamba, limasunga FPSO pamalo ake pamwamba pa munda. Chachiwiri, limagwira ntchito ngati malo olumikizirana pakati pa makina opanga pansi pa nyanja ndi FPSO, kutumiza madzi a chitsime, mphamvu zamagetsi, ndi zizindikiro zowongolera. Makina ena a SPM alinso ndi kutsekedwa kwadzidzidzi, zomwe zimathandiza FPSO kuchoka ndikupita kumalo otetezeka nyengo ikavuta.
Mu 2023, chingwe choyamba chachitsulo chomangira chokhazikika chopangidwa mdziko muno ku China chinayikidwa bwino pa FPSO Nanhai Fenjin, zomwe zikusonyeza kupita patsogolo kwa ukadaulo wa malo omangira chomangira chokhazikika.
05 Mapasa a Digito: Kuchokera ku Opaleshoni ya Akhungu mpaka Kukonza Zinthu Zooneka
Ma FPSO amakhala ndi zida zambiri, makina ovuta, komanso ali ndi chiopsezo chachikulu cha chitetezo. Mu ntchito zachikhalidwe, oyang'anira amadalira deta yosiyana siyana ya masensa ndi malipoti a mbali ziwiri. Ngati china chake chalakwika, zimakhala zovuta kupeza mwachangu chomwe chimayambitsa vutoli.
Ukadaulo wa mapasa a digito ukusintha izi.
Mwachitsanzo, FPSO yoyamba yanzeru ku China, Haiyang Shiyou 123, imagwiritsa ntchito ukadaulo wa digito kuti ikwaniritse kayendetsedwe ka digito ka kapangidwe ka sitimayo, njira zopangira, komanso momwe zida zilili. Akatswiri m'malo owongolera sitimayo amatha kuyang'anira kupanga sitimayo m'nyanja pogwiritsa ntchito "kachitidwe ka digito" ka sitimayo.
Pogwiritsa ntchito nsanja zamapasa a digito, ogwiritsa ntchito amatha kupanga mapasa a digito a 3D odalirika kwambiri a FPSO:
Kuwonetsera Kapangidwe ka Hull:Kubwezeretsa kwa ma module a thunthu ndi pamwamba pa mutu, kuthandizira kuwona zinthu motsatira magawo ndi kusakatula motsatira njira yoyesera.
Kujambula Mapu a Mkhalidwe wa Zipangizo Pa Nthawi Yeniyeni:Deta ya masensa pa kutentha, kuthamanga, kugwedezeka, ndi kuchuluka kwa madzi imayendetsa mosinthasintha momwe chitsanzo chilili. Zovuta zimayambitsa machenjezo odziyimira okha okhala ndi mitundu.
Kuyeserera kwa Kuyenda kwa Njira:Kuwonetsedwa kwa njira yonse yolekanitsira mafuta ndi gasi ndi madzi, kukonza, kusunga, ndi kutsitsa.
Kuwunika kwa Makina Oyendetsera Mapaipi:Kuwonetsa nthawi yeniyeni momwe turret ilili komanso kupsinjika kwa unyolo wa nangula, ndi chenjezo loyambirira la kusuntha kosazolowereka.
Kutsitsa Chithunzi cha Ntchito:Kuyerekezera ntchito zotsitsa katundu pansi pa mikhalidwe yosiyanasiyana ya panyanja.
Mapulatifomu awa amathandizira kupeza mitundu yoposa 30 ya magwero a deta, nyumba zokokera ndi kusiya popanda ma code, komanso mapulogalamu am'deralo ndi zida zosinthira. Amagwiritsidwa ntchito kwambiri popanga zombo ndi uinjiniya wapamadzi, mphamvu ndi mphamvu, komanso kupanga mwanzeru. Kaya ndi ma FPSO, zida zobowolera, kapena malo osungira magetsi a LNG, makina awiri a digito amatha kugwiritsidwa ntchito mwachangu kuti asinthe kayendetsedwe ka mphamvu zakunja kuchokera ku "kuyankha kosachitapo kanthu" kupita ku "chenjezo loyambirira."
