Kwese pasirese, kugadzirwa kwemafuta ekumahombekombe uye gasi kunoda hunyanzvi uye hwakaomarara pombi mhinduro uchishandisa zvemhando yepamusoro zvinhu.Hazvichashamisi kuti makambani emafuta adhire oiri kupfuura 10,000 metres pasi pevhu.
Kuve nechokwadi chekuita purofiti yenguva refu, chero sosi inofanira kushandiswa kweanenge makore makumi maviri nemashanu. Germany's Schoeller Werk inopa mupiro wayo kune inodiwa mhando uye vimbiso yekuronga neyayo inorema-basa rekutonga-mutsara & makemikari-jekiseni mapaipi eindasitiri yekumahombekombe. Germany's Schoeller Werk inopa mupiro wayo kune inodiwa mhando uye vimbiso yekuronga neyayo inorema-basa rekutonga-mutsara & makemikari-jekiseni mapaipi eindasitiri yekumahombekombe.Kambani yeGerman Schoeller Werk inobatsira kune inodiwa mhando uye kuronga nekugadzira inorema basa rekutonga mitsara uye makemikari jekiseni pombi kumahombekombe indasitiri.Schoeller Werk kuGermany inobatsira kune inodiwa mhando uye kuronga neinorema basa rekudzora mitsara uye makemikari jekiseni pombi yeindasitiri yekumahombekombe.Dhizaini yavo yehunyanzvi inovabvumira kutsungirira kwete chete kudzvanyirira kwakanyanya kunowanikwa mugungwa rakadzika, asiwo yakanyanya kupisa tembiricha uye corrosive liquid media.
Pasi rose, zvinopfuura zviuru zviviri zvezvicherwa zvekumahombekombe uye matsime akawanda akazvimiririra anoramba achigadzira oiri negasi.Midziyo yehunyanzvi yezvidyarwa izvi inoisa zvakanyanya kudiwa kune vakanyatsosarudzwa simbi isina tsvina.Schoeller Werk akatora dambudziko iri mugungwa makore makumi matatu nemashanu apfuura uye anga ari mutungamiri muindasitiri kwemakore mazhinji.Nzvimbo yekambani muEifel haingogadziri mapaipi emaindasitiri akasiyana, asi inopawo hunyanzvi hwekugadzirisa madhiri ekuchera.
Kune imwe kambani, TCO Norway, Schoeller Werk, mupi webasa kukambani yemafuta ehurumende yeNorway, akaendesa mapaipi anopfuura 500,000 metres kubva pakugamuchira odha kubva kune mutengi muchirimo che2014. Kudyidzana uku kunobva pamhando yepamusoro nickel based alloys.825 uye 625. Austenitic 316 Ti machubhu esimbi asina tsvina anowanikwawo.Mapaipi akaunzwa akafadza Statoil zvakanyanya zvekuti yakaatsanangura seyero yezvayakataura.Mukuwedzera kune zvakasiyana-siyana zvezvinhu, zvakasiyana-siyana zvemadhayamita nemadziro emadziro zvinofanira kugadzirwa - Sierra Schöller mapaipi anovhara zvose zvingaita.Iyo pombi dhizaini uye yakabatana yemhando bvunzo inobvumira mhinduro yekupedzisira kumirisana nemukati memukati kusvika ku2500 bar pasina matambudziko.Pamusoro pezvo, zvinhu zvemhando yepamusoro, pamwe nekuvandudzwa kwepamusoro pemhando yakawanikwa kubva mukuita kudhirowa waya, zvinopokana nemvura yemunyu nedzimwe nzvimbo dzakaoma.
Chimwe chezvinhu zvepombi yekuisa ndeye geometrically chaiyo kubhenda uye yakakwirira welding mhando.Muchidimbu, iyo base zvinhu hazvina basa uye mapaipi imwechete anosvika 2000 metres kureba anogona kugadzirwa.Internal mandrels (plugs) anoshandiswa kuenzanisa nzvimbo yemukati ye longitudinal seams.Mukubatana nekunze mandrel, yekutanga pombi cross-section inogona kuderedzwa kusvika ku50%.Pakazere, iyi inguva yakareba yakakwenenzverwa mhinduro inopa fungidziro yepombi isina musono.Kucherechedzwa kweiyo microstructure yezvinhu kwakaratidza kuti weld yaive isingaonekwe kunyangwe mushure mekunge pombi yadhonzwa.Aya hunhu ndiwo mabhenefiti akakosha kune Schoeller Werk offshore vatengi.
Muindasitiri yekumahombekombe, mapaipi aya anoshandiswa se hydraulic control mitsara yemavharuvhu ekuyamura uye kupomba makemikari mumadhiza emafuta.Nokudaro, vanotsigira hurongwa hwose hwekuchera.Majekiseni mapaipi anobvumira vanogadzira rig kutungamira makemikari kunyungudutsa oiri, nekudaro inovandudza kuyerera kwayo.Sechikamu chemaitiro akaoma ekugadzira, mapaipi anoiswa pasi pekuyedzwa kwakasiyana asati aiswa kuti ave nechokwadi chemhando yepamusoro yechigadzirwa.Metal mitsetse inobatanidzwa pamwechete pakureba seams vachishandisa tungsten inert gas welding (TIG) process uye yozomonywa kuita machubhu.Kuwedzera kune inosungirwa eddy ikozvino bvunzo, iyo chubhu inozoiswa pasi pemvura bvunzo yemhepo (AUW kana "bubble").Iyo chubhu inonyudzwa mumvura uye izere nemhepo inosvika 210 bar.Ita ongororo yekuona pamwe nehurefu hwose hwepombi kuti uone kuti dzakasimba.Kuti Schoeller Werk ipe vatengi vayo hurefu hunodiwa hwemamita 15 000 kana kupfuura, pombi imwe neimwe inomhanya inobatanidzwa pamwe chete uye X-rayed kutarisa kuti welds dzakasimba uye kuti hapana maburi emhepo.
Schoeller Werk zvakare hydraulically bvunzo kutonga uye kumanikidza pombi isati yaendeswa kune mutengi.Izvi zvinosanganisira kuzadza coil yakapedzwa nemafuta ehydraulic uye kuimanikidza ku2,500 bar kuti itevedzere mamiriro akanyanya anombosangana nawo mumabasa ekumahombekombe.
Pamusoro pekugadzirwa kwepombi yakachena, Schoeller Werk inopawo vatengi muindasitiri yemakungwa sevhisi yakazara sevhisi, senge yekuisa chisimbiso mapaipi ane epurasitiki sheath mune anonzi flat mapaketi.Izvi zvinoreva kuti chubhu bundle inogona kubatanidzwa kune yekubvisa chubhu uye yakadzivirirwa kubva pakukotama nekutsikirira.Mamwe masevhisi anosanganisira kugezesa nekuzadza pombi.Pano, mukati mepombi inoputirwa ne hydraulic fluid kusvikira mvura yasvika kune imwe ISO kana SAE yehutsanana.Mvura inosefa inogona kuramba iri mupombi kana mutengi achiida, kureva kuti mushandisi ane chigadzirwa chekushandisa.Mukuwedzera, masumbu echubhu anogona kupihwa netambo dzesimbi isina tsvina kana tambo dzekutakura.Mukuwedzera, nekuda kwemukati wakatsetseka pamusoro, iyo yekuisa chubhu yakanyatsokodzera kushandiswa senzira yekutapurirana kwetambo dze optical.
