Ezi tanki zibonelela ngemali eninzi yeendleko zexesha elide ngenxa yeemfuno zolondolozo lwenkonzo kunye nenkonzo eyandisiweyo. Inkqubo yabo yokufaka isebenza ngokufanelekileyo inegalelo kwinkqutyana yeprojekthi iphela.
Amanyathelo okubambisa iitanki ze-Wooliyo ezibandakanya ukhuseleko lokukhusela, ukukhuselwa kwe-cathodi, ukuphucula iimeko zokugcina, ukukhetha izixhobo zokungavisisani, kunye nokomeleza ulawulo lwemihla ngemihla.
Itanki engaphantsi komhlaba engaphantsi komhlaba yenzelwe ukubonelela ngokuziphatha okungafunekiyo kunye nobomi obude, kukwenza ukhetho olufanelekileyo lweemfuno zexesha elide zokugcina amafutha.
I-suble-clueren ephantsi kwetanki yepetrol ibonisa iqokobhe elingaphandle elinamandla kunye netanki yangaphakathi, ibonelela ngomaleko ongezelelweyo wokukhusela ekuvuzaneni.
Itanki engaphantsi komhlaba iyilelwe ngokukodwa ukujongana nale miceli mngeni, ijolise ekunikezeleni isisombululo sokugcina esikhuselekileyo.
Inqaku eliphambili lokuthengisa kwisikhululo sepetrol yethu i-petrol kukungafikeleli kunye nokuziqhelanisa. Ihamba ngokulula, iyenza ilungele iimeko zexesha elifutshane ezinamafutha anjengezindawo zokwakha, imisebenzi yokubeka emgodini, kunye nemisebenzi yomincili yentlekele.
