Izifundo zobunjineli ezibandakanyekayo kwisiqinisekiso sokuhamba zidlala indima ebalulekileyo ekwenziweni kweemephu iimfuno ezinciphisa okanye zithintele ilahleko yemveliso ngenxa yokuvaleka kwemibhobho okanye inkqubo yokuvala izixhobo.Iityhubhu ezidityanisiweyo ezisuka kwi-Meilong Tube zifakwa kwi-umbilicals kunye neenkqubo zokutofa ngemichiza zidlala indima esebenzayo kugcino lwekhemikhali kunye nokuhanjiswa kwesiqinisekiso sokuhamba kakuhle.
Umbhobho omncinci we-diameter oqhutywa ecaleni kwee-tubular zemveliso ukwenza inaliti ye-inhibitors okanye unyango olufanayo ngexesha lemveliso.Iimeko ezinje nge-hydrogen sulfide ephezulu [H2S] okanye ukubekelwa isikali esiqatha kunokuchaswa ngokutofwa kweekhemikhali zonyango kunye nezithinteli ngexesha lemveliso.
Igama eliqhelekileyo leenkqubo zokutofa ezisebenzisa izisombululo zeekhemikhali ezikhethekileyo zokuphucula ukubuyiswa kwe-oyile, ukususa umonakalo owenziweyo, ukucoceka kwe-perforations evaliweyo okanye iileya zokwakheka, ukunciphisa okanye ukuthintela ukubola, ukuphucula i-oyile ekrwada, okanye ukulungisa imiba yokuqinisekisa ukuhamba kweoli ekrwada.Isitofu sinokuqhutywa ngokuqhubekayo, kwiibhetshi, kwimingxuma yokutofa, okanye ngamanye amaxesha kwimithombo yemveliso.
