I-Drilling Riser

Emisebenzini yokumba ogwini, iukubhoboza isikhuphukeliisebenza njengesixhumanisi esibalulekile se-tubular esijoyina i-i-subsea wellhead and blowout preventer (BOP)kweisiteji sokumba ngaphezulu.
Kunokuba isebenze njengengxenye yesakhiwo esihlala njalo-njengepayipi le-conductor{1}}isikhuphukeli sisebenza njengeokwesikhashana,{0}}okuphakeme kobuqothoesetshenziswa kuphela ngesikhathi sokumba.

Inhloso yawo eyinhloko ukusungula aindlela elawulwayoukuze kujikelezwe uketshezi lokumba, ukusikwa, kanye{0}}nokulawula kahle izingcindezi phakathi kolwandle kanye nesitezi sokumba.
Lokhu kujikeleza kwe-loop-okuvaliwe kunika amandla ibhalansi yokucindezela, ukutholwa koketshezi, kanye nokuqapha komthombo okuqhubekayo kuyo yonke inqubo yokumba.

Kui-deepwater kanye-namanzi ajulile kakhuluukusebenza, lapho ukufinyelela okuqondile emithonjeni yemithombo engaphansi kolwandle kungenakwenzeka, isikhuphukeli siba yingxenye ebalulekile yohlelo lokulawula umthombo.
Kumelwe ibekezelele ukuguquguquka kolwandle okuyinkimbinkimbi, okuhlanganisa ukuphakama okuqondile, ukukhukhuleka kwamanje, kanye nemithwalo ye-hydrostatic-ngokuvamile ekujuleni okukhulu kuno2,000 amamitha.

Imihlangano yesimanje yesikhuphukeli ihlanganisaamajoyinti okungezwani, amamojula we-buoyancy, nezinto zokuvala uphawueziqinisekisa ngokuhlanganyela ukuzinza kwemishini, ukunqanda ingcindezi, kanye nokuphepha kokusebenza ngaphansi kwezimo ezishintsha njalo zasogwini.

A ukubhoboza isikhuphukeliisebenza njengesixhumanisi esiyinhloko somshini kanye ne-hydraulic phakathi kwe-surface rig kanye nesistimu yemithombo engaphansi kolwandle, iqinisekisa ukulawula okuqhubekayo nokuxhumana ngesikhathi sokumba ogwini.
Ukucushwa kwayo kuhlanganisa imisebenzi eminingi ekhethekile esebenza ndawonye ukuze kugcinwe ukuzinza nokusebenza nokuphepha{0}ezimeni zolwandle ezivulekile.

• Indlela Yokubuya Ye-Hydraulic:Isikhuphukeli sisungula i-annulus evaliwe yokubuyisela udaka, okuvumela ukuthuthwa okuphumelelayo kokusikwa nokugcina umfutho oqondile{0}}ongaphansi kwembobo.
• Well Pressure Regulation:Imigqa yokuklinya neyokubulala ehlanganisiwe ivumela ukusebenza kwengcindezi ephethwe, inikeze imvilophu yesibili yokuphepha yobuqotho bomthombo.
• Izindawo zokuhlala ezengeziwe e-Motion:Ngenhlanganisela yamajoyinti aguquguqukayo, izindandatho ezicindezelayo, nezinto ezinyakazayo, isikhuphukeli sihlala siqondile naphezu kokuphakama kwerig kanye nokugudluzwa kwezinhlangothi.
• Umgogodla Wesakhiwo:Isekela izintambo zokulawula ezisizayo futhi inikeza indlela eqinile kodwa eguquguqukayo yezinhlelo zemishini neziwuketshezi ezixhuma isitaki ne-BOP.
• Ukusebenziseka Kabusha Kokusebenza:Ukwakhiwa kwe-modular kuvumela isikhuphukeli ngasinye ukuthi sihlukaniswe, sihlolwe, futhi{0}}siqinisekiswe kabusha, kuqinisekiswe{1}}ukusebenza kahle kwezindleko zesikhathi eside kuyo yonke imikhankaso eminingi yokumba.

Ngayinye yalezi zici zomklamo ibonisa indima yesikhuphukeli njengeuhlelo lwesakhiwo esinamandla, akhiwe hhayi nje kuphela ukuze aqukathe ukucindezela kodwa ukuze alondoloze isigqi esiwumshini sokumba amanzi ajulile.

NgoIpayipi le-Octal, izikhuphukeli zokubhola zenziwe ngobunjiniyela futhi zihlolwe ukusebenza ngaphansiizimo ezimbi kakhulu zasolwandle.

Ukukhetha Okubalulekile

Amandla aphezulu-aphansi{1}}izinsimbi ze-alloy ezinhle kakhuluukukhathala nokumelana nokuphuka.

Okukhethekileezinengilazi kanye nokuvikelwa cathodicizinhlelo ezilwa nokugqwala kwamanzi olwandle.

Ukucushwa Kwedizayini

Yenza ngokwezifisoamalunga okuphakama, amalunga e-tension, futhiama-flex jointsngezinhlobo ezahlukene zama-rig.

Ukuhlanganiswa kweamamojula we-buoyancyukunciphisa isisindo sohlelo nokuthuthukisa ukuzinza okuqondile.

Ukuhlanganisa kokuvala kwangaphakathi okuklanyelwe ukuvuza-kukusebenza okuqinile ngaphansi kwengcindezi ephezulu.

Ukuqinisekisa ikhwalithi

Ukuhlola{{0}Okungabhubhisi (NDT):I-Ultrasonic, i-particle magnetic, nokuhlolwa kwe-radiographic of welds.

Ukuhlolwa kwe-Hydrostatic:Ukuqinisekiswa komfutho wamanzi ajulile okulingiswayo.

Ukuhlola Ukukhathala Nokugqwala:Kwenziwa ngaphansi kwezimo zemvelo zasolwandle.

Kuqinisekiswe ngokushoI-APIfuthiI-DNV-GLamazinga ezicelo zasolwandle.

🔹 Isiphetho:
Amapayipi ekhondatha ahlinzeka ngesisekelo sesakhiwo emanzini angashoni; izikhuphukeli zokumba zelula ukulawula ukusebenza emanzini ajulile. Ndawonye, ​​bakha uhlelo lokuhlanganisa ibhulohoubuqotho bolwandlefuthiimisebenzi ebusweni.

Izikhuphukeli zokumba zibalulekile emanzini ajulile kanye{0}}emisebenzini yamanzi ajulile kakhulu lapho ukugeleza koketshezi okuthembekile nokulawula ukucindezela kuwumgomo-ubalulekile.

Deepwater Exploration (> 2,000 m):Inika amandla ukufinyelela okuphephile ekubunjweni kolwandle olungaphansi kolwandle emibhedeni yasemngceleni njengeGulf of Mexico, ogwini lwaseBrazil, futhieNtshonalanga Afrika.

I-Dynamic Offshore Environments:Isetshenziswa kumarigi antantayo, -ama-submersibles, kanye nama-drillship anesistimu{1}}enxephezelwe yokukhuphukela phezulu.

Imithombo ye-HPHT ({0}}Ephezulu-Yezinga Lokushisa):Ihlinzeka ngokuvinjelwa okuphephile kwezingcindezi ze-downhole ezidlulele kanye nama-gradients okushisa.

Ukuhlanganiswa ne-BOP Systems:Isekela ukusebenza kolayini wokuklinya nokubulala, okuvumela ukuvala{0}ngaphakathi ngokushesha phakathi nezimo eziphuthumayo.

Ukusebenza Nokungenelela:Kabusha{0}amasistimu okukhuphukela phezulu angasebenziseka ukuze anakekele futhi aqedele imisebenzi emithonjeni eminingi.

Isibonelo Sobunjiniyela:
Ezindaweni zase-Brazilian ultra-zamanzi ajulile, izikhuphukeli zixhuma ama-submersible-ama-submersible nama-wellheads ekujuleni ngale2,500 m. Ngisho nangaphansi kobude begagasi obungu-10 m, izikhuphukeli eziqinile zigcina ukuzinza nokulawula{2}}okufakazela indima yazo ebalulekile kubunjiniyela besimanje be-offshore.

Yonke imikhankaso yokumba emanzini ajulile incike ekuthembekeni kwesikhuphukeli ukuze sigcine ukulawulwa kwemithombo okuphephile nokungashintshi.
NgoIpayipi le-Octal, isistimu yesikhuphukeli ngasinye yakhelwe ukusebenza ngaphansi kwemithwalo ejikelezayo, ingcindezi ye-hydrostatic, nokuchayeka emanzini olwandle agqwalile ngokwethembeka okungayekethisi.

• Ukuqina Okuthuthukisiwe:Ukuhlaziywa kokukhathala okusekelwe kusici esiphelile kuqinisekisa ukukhuthazela ngokumelene nokulayisha okuphindaphindayo okunamandla.
• I-Marine-Proven Coatings:Ukuvikelwa -okulwa nokugqwala{1}}kwezendlalelo eziningi kunciphisa ukuwohloka ngesikhathi sokucwiliswa isikhathi eside ngaphansi kolwandle.
• Ukuhambelana Kwesistimu Ehlanganisiwe:Idizayinelwe ukusebenzelana okungenamthungo ngezitaki ze-BOP, ama-tensioner, namasistimu okucindezela akhuphukayo olwandle.
• -Ukuqinisekiswa Okugcwele Komjikelezo:Kusukela ekutholeni isitifiketi kuya ekuhlolweni kokwamukelwa kwasembonini kanye nezilingo zasolwandle ezilingisayo, isikhuphukeli ngasinye siphumelela ukuqinisekiswa kokusebenza okuqinile.

Lezi zinyathelo zenzaI-Octal Pipe yokumba izikhuphukeliukukhetha okuthembekile kosonkontileka abaphesheya kwezilwandle abafunaukwethembeka okuqhubekayo, ukuphepha kokusebenza, kanye nokusebenza okubikezelwayoekujuleni kwamanzi okudinga kakhulu.

Ubunjiniyela obufakazelwe beamanzi ajulile kanye ne-HPHTizicelo.

Ukuhambisana neI-API / DNV-GL / ISOizindinganiso zasolwandle.

Ukuvikelwa kwempahla okuthuthukisiwe kanyeNDT-isilawuli sekhwalithi esiqinisekisiwe.

Amasistimu okukhuphukela phezulu adizayinelwe umhlaba wonkeI-EPC kanye nosonkontileka abambayo.

Kufakwe imibhalo yobuchwepheshe, ukugunyazwa kabusha, nokusekelwa kwephrojekthi.

Okokwethenjelwa,-amasistimu okukhuphuka aqinisekisiwe avikela imisebenzi yokumba ogwini{1}}I-Octal Pipe iletha ukuzethemba kuwo wonke amalunga.
