Failure hom thiab cov teebmeem kev tsom xam yog cov txheej txheem ntawm kev tshuaj xyuas ntau yam, sib dhos, thiab subsystems raws li qhov ua tau los txheeb xyuas cov kev ua haujlwm tsis zoo hauv lub cev thiab lawv cov laj thawj thiab cov teebmeem. txo lawv qhov cuam tshuam. Tsis tas li ntawd, nws tuaj yeem txhim kho qhov zoo, kev cia siab, thiab kev nyab xeeb ntawm lub kaw lus lossis cov khoom. Qhov no tuaj yeem ua rau cov neeg siv khoom txaus siab thiab kev ncaj ncees, nrog rau kev txo nqi thiab kev pheej hmoo cuam tshuam nrog kev ua tsis tiav.FMEA feem ntau suav nrog tsib kauj ruam hauv qab no:
Kauj Ruam 1: Nug seb qhov kev lag luam twg muaj teeb meem?
Kauj Ruam 2: Tsim ib pab neeg uas tuaj yeem ua haujlwm ua ke.
Kauj ruam 3: Qhia thiab piav qhia tag nrho cov kauj ruam.
Kauj Ruam 4: Txheeb xyuas cov hom kev ua tsis tiav.
Kauj Ruam 5: Ua qhov tseem ceeb raws li RPN.
Tau kawg, peb tuaj yeem siv FEMA hom rau kev tshuaj xyuas zoo ntawmmarine li qub.
Kauj Ruam 1: Txheeb xyuas qhov muaj peev xwm ua tsis tiav hom
Sau txhua txoj hauv kevmarine li qubtuaj yeem ua tsis tiav (piv txwv li, to, corrosion, mechanical breakdown).
Kauj Ruam 2: Txheeb xyuas qhov ua rau thiab qhov cuam tshuam
Xav txog cov theem sib txawv: tsim, tsim khoom, thiab kev ua haujlwm.Txhim lub hauv paus ua haujlwm ntawm txhua hom kev ua haujlwm tsis ua haujlwm.Tshuaj xyuas cov teebmeem ntawm txhua qhov tsis ua haujlwm ntawm lub cev, kev nyab xeeb, thiab kev ua haujlwm.
Kauj Ruam 3: Xam Xaj Tus Naj Npawb Risk Priority (RPN)
Ntsuas qhov hnyav (S), qhov tshwm sim (O), thiab kuaj pom (D) ntawm txhua hom kev ua haujlwm tsis ua haujlwm.Xa cov qhab nia rau qhov hnyav, qhov tshwm sim, thiab kuaj pom.
Xam RPN rau txhua hom tsis ua haujlwm: RPN = S × O × D.
Kauj Ruam 4: Txhim Kho Cov Kev Ua Kom Txom Nyem
Ua ntej cov qauv ua tsis tiav raws li lawv cov RPNs.Tom ntej ntawm cov khoom RPN siab ua ntej.Ua cov kev kho kom raug xws li kev hloov pauv tsim, hloov khoom siv, thiab kev sim ua kom zoo dua.Tsim kev tiv thaiv thiab kev tswj xyuas kom zoo.
Kauj Ruam 5: Ua thiab saib xyuas
Muab cov kev kho kom raug rau hauv cov txheej txheem ntau lawm.Nruam saib xyuas kev ua haujlwm ntawm lub valve thiab kev ua haujlwm ntawm kev txo qis.
Kauj Ruam 6: Tshawb xyuas thiab Hloov Kho
Kev hloov kho FMEA tsis tu ncua nrog cov ntaub ntawv tshiab thiab kev nkag siab.Ua ntu ntu kom ntseeg tau tias FMEA tseem nyob tam sim no.Ua kev hloov kho raws li kev tawm tswv yim, cov thev naus laus zis tshiab, thiab cov txheej txheem txhim kho.
Los ntawm kev hais daws cov kev ua tsis tau zoo, FMEA pabmarine valves lwm tus neegthiabmarine valve manufacturerstxhim kho qhov zoo thiab kev ntseeg siab ntawm lawv cov khoom.
