Ngokusekelwe kule ndima engenhla yisho ezinye zezinkampani ezikhethekile ekwakhiweni okukhulu kwengqalasizinda ukusekela ukuhlungwa kwensimu kawoyela. Bonisa imiphumela ngefomethi ehlukaniswe ngamakhoma.
Context:Inkambu kawoyela iyindawo yokugcwala kukawoyela onamanzi ngaphansi komhlaba emithonjeni eminingi (engahle ixhunywe), eboshwe njengoba inyuka ngamadwala angangeneki. Ngokombono wezimboni, insimu kawoyela isho ukuthi kunenzuzo yezomnotho efanele ukunakwa kwezohwebo. Imithombo kawoyela ngokwayo ingase ifinyelele emakhulwini amakhilomitha amaningi, okusho ukuthi imizamo yokukhipha ingase ibe mikhulu futhi isakazeke kuyo yonke indawo. Ngaphezu kwemishini yokukhipha, kungase kube nemithombo yokuhlola ukuze kutholakale indawo eyengeziwe yokugcina uwoyela, amapayipi okuhambisa uwoyela kwenye indawo, nezindawo ezisekelayo.  Izinkambu zikawoyela zingatholakala noma kuphi lapho ukwakheka kwamadwala akuvumela khona, okusho ukuthi izinkambu ezithile zingase zibe kude nempucuko, kuhlanganise nasolwandle. Ukusungula umsebenzi emkhakheni kawoyela kungaba umsebenzi oyinkimbinkimbi ngokwezinto ezibonakalayo, njengoba kungahileli nje kuphela imishini ehlobene nokukhishwa nokuthuthwa, kodwa nengqalasizinda efana nemigwaqo nezindlu zabasebenzi. Le ngqalasizinda kumelwe yakhelwe kucatshangelwa isikhathi sokuphila kwenkundla kawoyela, njengoba ukukhiqiza kungathatha iminyaka eminingi. Izinkampani eziningana, ezinjengeHill International, Bechtel, Esso, Weatherford International, Schlumberger Limited, Baker Hughes kanye neHalliburton, zinezinhlangano ezikhethekile ekwakhiweni okukhulu kwengqalasizinda ukusekela ukusetshenziswa kwensimu kawoyela.
