Iintambo ze-Downhole zisebenza kwezinye iindawo ezinzima kakhulu zemizi-mveliso, apho ukungaphumeleli kunokukhokelela ekunciphiseni iindleko kunye neengozi ezinzulu zokhuseleko. Ukuqinisekisa{1}}ukhuseleko lwexesha elide kunye nokuthembeka, abavelisi beentambo ze-downhole basebenzisa inzululwazi yezinto eziphambili, iiprothokholi zovavanyo olungqongqo, kunye neenkqubo ezingqongqo zolawulo lomgangatho ezihambelana nemigangatho yamazwe ngamazwe. Eli nqaku licacisa indlela abavelisi abayila ngayo, bavavanye, kwaye baqinisekise iintambo zomngxuma osezantsi{3}}kwaye kufuneka abathengi bavavanye ntoni ukuze bakhethe umthengisi othembekileyo ngokuzithemba.
Zeziphi iimathiriyeli kunye noyilo ezenza iintambo zomngxuma ongaphantsi komhlaba zomelele ngokwendalo?
Abavelisi bakhetha umhlwa-izikhonduki ezixhathisayo kunye nezikrweqe (iialloyi ezingenastainless, i-nickel{1}}i-alloys),{2}}i-insulation ephezulu ({3}}i-polyethylene edityanisiweyo, ii-elastomers ezikhethekileyo) kunye nezixhobo zobuchule ezilayelweyo ukuxhathisa imithwalo, i-abrasion kunye nohlaselo lwekhemikhali. Uyilo luhlala lulandela isikhokelo se-subsea / umbilical (ukukhethwa kwezinto, ukulinganiswa koxinzelelo) ezisetyenziswe kwi-ISO 13628 series for umbilicals kunye ne-subsea cables - ukuqinisekisa ukuba izixhobo kunye nejometri zikhethwa kwiimeko ezijoliswe kuzo.
Abavelisi bakuqinisekisa njani ukugquma kunye nokuthembeka kombane phambi kokunikezelwa?
Insulation imfezeko iqinisekiswa ngovavanyo lombane olusemgangathweni olufana novavanyo lwe-dielectric{0}}withstand (hipot), i-partial discharge (PD) imilinganiselo kunye novavanyo lokumelana nobushushu. Uvavanyo lokumelana neHipot/dielectric ichonga ukugqunywa komda; Uvavanyo lwePD lufumanisa i-voids okanye inclusions enokukhula phantsi koxinzelelo. Olu vavanyo luqhele ukwenziwa kwisikhokelo sovavanyo lwe-IEC/IEEE yamandla kunye neentambo ezizodwa.
Zeziphi iimvavanyo zoomatshini nezokusingqongileyo ezingqina ukuba intambo iya kusinda equleni?
Abavelisi benza iimvavanyo zokuqina kunye nobude, uvavanyo lokugoba kunye nokuguquguquka, uvavanyo lokutyumza kunye ne-abrasion, ubushushu -ukukhwela ibhayisekile, uxinzelelo lwe-hydrostatic kunye novavanyo lokuntywiliselwa kweekhemikhali. Kumacandelo angaphantsi kwamanzi, uvavanyo lulandela i-ISO 13628 isikhokelo sokuqinisekisa uyilo (uxinzelelo, imithwalo yomatshini). Ukulandelwa kwezinto eziphathekayo kunye neendlela zokwamkelwa zirekhodwa kwiZicwangciso zokuHlola kunye noVavanyo (ITP).
Iinkqubo ezisemgangathweni kunye nokulandeleka ziwunciphisa njani umngcipheko wokungaphumeleli?
Intambo ye-JSH ulawulo (ISO 9001, ii-ITP ezibhaliweyo), uhlolo lwemathiriyeli engenayo, ukulandelelwa kwebhetshi,{1}}iirekhodi zeemviwo ezingonakalisiyo kunye nokulandeleka okuninzi kwamacandelo kunciphisa isixokelelwano sobonelelo kunye nobungozi bokwenziwa. Abavelisi abaphezulu bagcina i-FMEAs ebhaliweyo (iMode yokungaphumeleli kunye nohlalutyo lweempembelelo) kunye nezicwangciso zokulawula amanyathelo enkqubo ebalulekileyo. Ubungqina bophicotho lwefektri kunye{4}}nezatifikethi zeqela lesithathu kwandisa ukuzithemba.
Ingaba abavelisi bavavanya njani kwaye baqinisekise-ukuthembeka kwexesha elide (ukuguga okukhawulezileyo)?
Iiprothokholi zokwaluphala ezikhawulezileyo zidibanisa ubushushu obuphezulu/ukufuma okuvezwayo, ukukhwela ibhayisekile kubushushu kunye nokuthambekela kombane ukuze kufane-iminyaka emininzi yobomi bentsimi. Iziphumo zihlalutyelwe ukuqhekeka kwe-insulation, i-conductor corrosion, utshintsho lwe-dimensional kunye nokunyuka kwePD. Uhlobo -lovavanyo kunye nokuguga kwesampulu zibonelela ngokuzithemba kwamanani phambi kokuba imveliso epheleleyo iqhutywe. Imigangatho yolawulo/yeshishini kunye neenkqubo zesiqinisekiso sangaphakathi zichaza imida yokwamkelwa.
Yeyiphi indima edlalwa ziilebhu zeqela lesithathu nemigangatho?
Iilebhu zokuvavanya ezizimeleyo, -uhlolo lweqela lesithathu kunye nokuthotyelwa kwemigangatho (ISO 13628 ye-subsea/umbilicals, i-IEC/IEEE yovavanyo lombane, i-ASTM yezixhobo) ibonelela ngeenjongo zokuqinisekisa. Iqela lesithathu -iqela elingqina uhlobo{4}}lovavanyo kunye novavanyo lwesiqhelo bubungqina obunamandla bokuba ukusebenza kwemveliso kuyahlangabezana nemilinganiselo eyamkelekileyo yoshishino.
Ukuthengwa kwempahla kufuneka kubandakanye ntoni kwiinkcukacha zokuthenga ukuqinisekisa ukhuseleko nokuthembeka?
Inkcazo yokuthenga eyomeleleyo (PO/Spec) kufuneka ibandakanye:
Inkcazo yemathiriyeli eneenkcukacha kunye neemfuno ze-MDS (amabakala e-alloy/insulation).
Uhlobo kunye nesiqhelo sovavanyo lwematrix (i-voltage ye-hipot kunye nobude bexesha, i-PD thresholds, i-tensile, i-bend, iimvavanyo zoxinzelelo).
Ukuhlolwa kunye neSicwangciso soVavanyo (ITP) kunye namanqaku obungqina kunye neendlela zokwamkelwa.
Ukulandeleka (amanani amaninzi, amanani obushushu), iimfuno zokupakishwa kunye nokuphatha.
Iimfuno zokufaneleka (uhlobo{0}}iingxelo zovavanyo, iziphumo zokuguga ezikhawulezileyo).
Ukulindela inkqubo yomgangatho (izatifikethi ze-ISO, amalungelo ophicotho-zincwadi).
I-AI/analytics disclosures (ukuba umthengisi usebenzisa imodeli yedatha) kunye nezibophelelo zokwabelana ngedatha ye-QC ngesicelo.
