Ukuthintela ukuvuthela okujikelezayo kufakwe phezulu kwe-BOP yonyaka. Ngexesha lemisebenzi yokugrumba engalinganiyo kunye neminye imisebenzi yokugaya uxinzelelo, isebenzela injongo yokuphambukisa ukuhamba ngokutywina umtya wokubhola ojikelezayo. Xa isetyenziswe ngokubambisana ne-BOP yokubhoboza, i-drill string check valves, i-oil-gas separators, kunye neeyunithi ze-snubbing, ivumela ukuqhutyelwa koxinzelelo olukhuselekileyo kunye nokusebenza kwe-snubbing. Idlala indima ebalulekileyo kwimisebenzi ekhethekileyo efana nokukhulula i-oyile enoxinzelelo oluphantsi kunye nemigangatho yerhasi, ukugrumba okungavuziyo, ukugrumba umoya, kunye nokulungiswa kwamaqula.
