Tambo dzeDownhole dzinoshanda mune dzimwe nzvimbo dzakaomarara dzemaindasitiri, uko kutadza kunogona kutungamira kune inodhura nguva yekudzikira uye njodzi dzakakomba dzekuchengetedza. Kuti tive nechokwadi chekuchengetedza-kwenguva yakareba uye kuvimbika, vagadziri vetambo dzepasi vanoshandisa sainzi yemhando yepamusoro, mitemo yekuyedza yakasimba, uye masisitimu akasimba ekudzora mhando anofambirana nezviyero zvepasi rese. Chinyorwa chino chinotsanangura kuti vagadziri vanogadzira sei, vanoedza, uye vanosimbisa tambo dzepasi-uye zvinofanirwa kuongororwa nevatengi kuti vasarudze mutengesi akavimbika nechivimbo.
Ndezvipi zvinhu uye magadzirirwo anoita kuti tambo dzepasi dzive dzakasimba?
Vagadziri vanosarudza corrosion-makondukita asingadziviriki uye nhumbi dzokurwa nadzo (stainless alloys, nickel-alloys), yakakwirira-performance insulation (cross-linked polyethylenes, specialty elastomers) uye akaturikidzana ezvombo zvezvombo zvinodzivirira kusimba, abrasion uye kurwisa kemikari. Madhizaini anowanzo kutevedzera subsea/umbilical kutungamira (kusarudzwa kwezvinhu, kudzvanywa ratings) anoshandiswa muISO 13628 akatevedzana eumbilicals uye tambo dzepasi pegungwa - kuve nechokwadi kuti zvinhu uye geometry zvinosarudzwa kune zvakanangwa pasi pemamiriro ezvinhu.
Vagadziri vanosimbisa sei insulation uye kutendeseka kwemagetsi vasati vauya?
Insulation integrity inopupurirwa nezviyedzo zvemagetsi zvakaita sedielectric-withstand (hipot) test, partial discharge (PD) kuyerwa uye kuyedza kudzivirira kudzivirira. Hipot/dielectric standstand test inoratidza kuvharwa kwemukati; Kuongororwa kwePD kunoona voids kana inclusions inogona kukura pasi pekunetseka. Iyi bvunzo dzinowanzo itwa kuIEC/IEEE bvunzo kutungamira kwesimba uye tambo dzehunyanzvi.
Ndedzipi dzemakanika uye dzezvakatipoteredza bvunzo dzinoratidza kuti tambo ichapona mutsime?
Vagadziri vanoita bvunzo dzekusimba nekurebesa, cyclical bending and flex test tests, crush and abrasion tests, tembiricha-kuchovha bhasikoro, hydrostatic pressure uye miedzo yekunyudza makemikari. Kune subsea / umbilical zvikamu, kuyedzwa kunotevera ISO 13628 gwara rekusimbisa dhizaini (kudzvanywa, mekiniki mitoro). Material traceability uye maitiro ekugamuchirwa akanyorwa muInspection uye Test Plans (ITP).
Ko maitiro emhando uye traceability anoderedza sei njodzi yekutadza?
JSH Cable manejimendi (ISO 9001, maITPs akanyorwa), kuongororwa kwezvinhu zvinouya, kurongeka kwebhetch, kwete{1}}marekodhi ebvunzo anoparadza uye kurongeka kwezvikamu zvinodzikisira njodzi dzekutengesa uye kugadzira. Vagadziri vepamusoro vanochengetedza zvakanyorwa maFMEAs (Kutadza Mode & Migumisiro Yekuongorora) uye zvirongwa zvekudzora zvematanho akakosha ekuita. Humbowo hwekuongororwa kwefekitori uye -yechitatu certification inowedzera kusatya.
Vagadziri vanoedza sei nekuona kuvimbika-kwenguva refu (kukurumidzira kuchembera)?
Mitemo yekuchembera yakasimirirwa inosanganisa kuratidzwa kwetembiricha/mwando, kuchovha bhasikoro uye kurerekera kwemagetsi kutevedzera-makore akawanda. Mhedzisiro inoongororwa kuparara kwe insulation, conductor corrosion, dimensional shanduko uye PD kuwedzera. Nyora-yedzo uye kuchembera zvinopa chivimbo chenhamba isati yazara kugadzira. Regulatory / indasitiri zviyero uye yemukati qualification maitiro anotsanangura kugamuchirwa zvikumbaridzo.
Ibasa rei rinoitwa-nemalebhu nemaitiro ebato?
Malebhu ekuyedza akazvimirira, -kuongororwa kwebato uye kutevedzera zviyero (ISO 13628 ye subsea/umbilicals, IEC/IEEE yebvunzo dzemagetsi, ASTM yezvishandiso) inopa humbowo hwechinangwa. Yechitatu-yemunhu yapupu yerudzi-yekuyedza uye yemazuva ese humbowo hwakasimba hwekuti chigadzirwa chinoenderana nezvinotemerwa zveindasitiri.
Chii chinofanira kutengwa nekutenga maficha kuti uve nechokwadi chekuchengetedza & kuvimbika?
Iyo yakasimba yekutenga yakatarwa (PO/Spec) inofanirwa kusanganisira:
Detailed material specs uye MDS zvinodiwa (alloy/insulation grade).
Type uye routine test matrix (hipot voltage & duration, PD zvikumbaridzo, tensile, bend, bvunzo dzekumanikidza).
Inspection & Test Plan (ITP) ine mapoinzi ezvapupu uye maitiro ekugamuchira.
Traceability (nhamba zhinji, nhamba dzekupisa), kurongedza uye kubata zvinodiwa.
Zvinodiwa zvekukodzera (mhando-yekuongorora mishumo, yakawedzera kuchembera zvabuda).
Quality system inotarisirwa (ISO zvitupa, kodzero dzekuongorora).
AI/analytics inoburitsa (kana mutengesi achishandisa data data) uye zvisungo zvekugovana data reQC pakukumbira.
