Waya z’okukka wansi zikola mu bimu ku bifo eby’amakolero ebisinga obukambwe, ng’okulemererwa kuyinza okuvaako okuyimirira okumala ssente n’obulabe obw’amaanyi obw’obukuumi. Okukakasa nti obukuumi n’okwesigamizibwa okw’ekiseera ekiwanvu-, abakola waya ezikka wansi bakozesa ssaayansi w’ebintu eby’omulembe, enkola enkakali ez’okugezesa, n’enkola enkakali ez’okulondoola omutindo ezikwatagana n’omutindo gw’ensi yonna. Ekiwandiiko kino kinnyonnyola engeri abakola dizayini, okugezesa, n’okukakasa obuwaya bwa Downhole-era abaguzi bye balina okwekenneenya okulonda omugabi eyesigika n’obwesige.
Bikozesebwa ki ne dizayini ki ezikola waya ezikka wansi mu butonde nga zinywevu?
Abakola ebintu balondawo okukulukuta-kondakita n’ebyuma ebiziyiza (alloys) ezitaliimu buziba, nickel-ebizigo), waggulu-okuziyiza okukola (okusala-okuyungibwa kwa polyethylenes eziyungiddwa, elastomers ez’enjawulo) n’ebyuma eby’ebyuma ebiteekeddwa mu layeri okuziyiza emigugu gy’okusika, abrasion ne abrasion n’okulumba eddagala. Designs zitera okugoberera subsea/umlibical guidance (ebintu okulonda, pressure ratings) ekozesebwa mu ISO 13628 series for umbilicals ne subsea cables - okukakasa ebikozesebwa ne geometry birondebwa ku mbeera y’okukka wansi ekigendererwa.
Abakola ebintu bakakasa batya insulation n’obulungi bw’amasannyalaze nga tebannatuusa?
Insulation integrity ekakasiddwa n’okugezesebwa kw’amasannyalaze okutuufu nga dielectric-okugezesebwa (hipot), okupima okufuluma ekitundu (PD) n’okugezesebwa okuziyiza okuziyiza. HIPOT/Dielectric okugumira okugezesebwa kuzuula marginal insulation; Okukebera PD kuzuula ebituli oba ebiyingizibwamu ebiyinza okukula nga biri ku situleesi. Ebigezo bino bitera okukolebwa ku IEC/IEEE test guidance for power ne specialty cables.
Biki ebigezesebwa mu by’okukanika n’obutonde bw’ensi ebikakasa nti waya ejja kuwona oluzzi?
Abakola okugezesa okusika n’okuwanvuwa, okubeebalama n’okunyiga ebiwujjo, okugezesa okubetenta n’okusika, ebbugumu-okuvuga enzirukanya y’amazzi, puleesa y’amazzi n’okugezesa okunnyika kw’eddagala. Ku bitundu ebiri wansi w’ennyanja/ebizimba, okugezesa kugoberera ISO 13628 Guidance for Design Verification (Pressure, Mechanical Loads). Emisingi gy’okulondoola n’okukkiriza ebintu giwandiikibwa mu nteekateeka z’okukebera n’okugezesa (ITP).
Enkola z‟omutindo n‟okulondoola bikendeeza bitya ku bulabe bw‟okulemererwa?
JSH Cable . Enzirukanya (ISO 9001, documented ITPs), okukebera ebintu ebiyingira, okulondoola batch, obutali-ebiwandiiko ebisaanyaawo ebigezo n’okulondoola looti ebitundu bikendeeza ku bulabe bw’okugaba n’okukola. Abakola ebintu eby’oku ntikko bakuuma FMEAs eziwandiikiddwa (Failure Mode & Effects Analysis) n’okufuga enteekateeka z’emitendera egy’enkola enkulu. Obujulizi bw’okubala ebitabo mu makolero n’okuweebwa satifikeeti y’ekibiina eky’okusatu-bwongera obwesige.
Abakola ebintu bagezesa batya era ne bakakasa okwesigamizibwa okumala ebbanga eddene-Termu (Accelerated ageing)?
Enkola z’okukaddiwa ez’amangu zigatta ebbugumu/obunnyogovu obugulumivu, okutambula kw’ebbugumu n’okusosola mu vvulovumenti okukoppa obulamu bw’ennimiro obw’omwaka multi-. Ebivuddemu byekenneenyezebwa okulaba oba bimenyawo ebiziyiza, okukulukuta kwa kondakita, enkyukakyuka mu bipimo n’okweyongera kwa PD. Ekika-Ebigezo n'okukaddiwa kwa sampuli biwa obwesige mu bibalo nga okufulumya mu bujjuvu tekunnabaawo. Emitendera gy’okulungamya/amakolero n’enkola z’ebisaanyizo eby’omunda bitegeeza emitendera gy’okukkiriza.
Omulimu ki ogw'okusatu-Party labs and standards zikola?
Independent Testing Labs, third-Okukebera n’okunywerera ku mutindo (ISO 13628 ku Subsea/Imbilicals, IEC/IEEE okugezesebwa kw’amasannyalaze, ASTM ku bintu) biwa okukakasa okutaliimu bukwakkulizo. Ekyokusatu-Ekika ky’ekibiina ekijuliziddwa-Okugezesa n’okugezesebwa okwa bulijjo bukakafu bwa maanyi nti enkola y’ebintu etuukiriza ebisaanyizo by’amakolero ebikkirizibwa.
Okugula ebintu kulina kuteeka ki mu kugula ebikwata ku kugula okukakasa obukuumi & okwesigika?
Enkola ey’amaanyi ey’okugula (PO/SPEC) erina okubeeramu:
Ebikwata ku bintu ebikwata ku bintu ebikwata ku bintu n’ebyetaago bya MDS (ebipimo by’okuziyiza okuyingira mu mubiri (alloy/insulation grades).
Ekika ne Matrix y’okugezesa eya bulijjo (Hipot Voltage & Duration, PD thresholds, okusika, okukoona, okugezesebwa kwa puleesa).
Inspection & Test Plan (ITP) nga erina ebifo by’abajulizi n’emisingi gy’okukkiriza.
Okulondoola (ennamba nnyingi, ennamba z’ebbugumu), ebyetaago by’okupakinga n’okukwata.
Ebyetaago by'ebisaanyizo (ekika-Lipoota z'okugezesa, ebivudde mu kukaddiwa okwanguyira).
Ebisuubirwa mu nkola y’omutindo (ISO satifikeeti, eddembe ly’okubala ebitabo).
AI/Analytics disclosures (ssinga omugabi akozesa data models) n’obuvunaanyizibwa okugabana data ya QC ku kusaba.
