Drilling ua haujlwm yuav tsum muaj cov khoom siv tswj cov khib nyiab (cov ntxaij vab tshaus vibrating, centrifuges, thiab lwm yam) los kho cov av nkos thiab tiv thaiv kev sib tsoo ntawm cov txiav; blowout Preventer (BOP) units kuj tseem tsim nyog los daws qhov kev pheej hmoo ntawm kev ncaws pob zoo. Kev saib xyuas niaj hnub suav nrog kev tshuaj xyuas cov rig hauv paus theem tsis tu ncua (kev ua yuam kev Tsawg dua lossis sib npaug li 0.5 degree), lubrication system roj siab (feem ntau 0.3-0.6 MPa), thiab nres lub ncoo hnav (hloov yog ntau tshaj 50% hnav). Nrog rau qhov sib txawv ntawm cov tshuab ntse, cov chaw taws teeb saib xyuas tuaj yeem xa cov ntaub ntawv xwm txheej hauv lub sijhawm thiab muab cov lus ceeb toom ntxov ntawm kev ua haujlwm tsis zoo.
