Isikhululo se-LNG esingajongwanga simele incopho yokuveliswa kwezinto ezintsha zobuchwepheshe kwiziseko ezingundoqo zamafutha. Idizayinelwe ukuba isebenze ngaphandle kokubekw' iliso rhoqo komntu, ibonelela ngoluhlu lwemisebenzi echaza kwakhona lula ukufakwa kwe-refueling. Ezi zikhululo zibonakalisa iinkqubo ezizenzekelayo zokugcinwa kwe-LNG, ukukhupha, kunye nokulawula ukhuseleko, okwenza kube lula ukunyusa isithuthi ngaphandle kwesidingo sabasebenzi besikhululo.

Izinto eziluncedo kwizikhululo ze-LNG ezingajongwanga zibandakanya ukufikeleleka okuphuculweyo, njengoko zisebenza ubusuku nemini, zinciphisa amaxesha okulinda kubasebenzisi. Ukungabikho kwabasebenzi kukwanciphisa iindleko zokusebenza kwaye kuqinisekisa ubulunga obungaguqukiyo bamafutha ngokusebenzisa iinkqubo ezichanekileyo. Ngaphezu koko, iindlela zokubeka iliso eziphambili kunye neendlela zokuphendula ngokukhawuleza ziqinisekisa ukhuseleko ngaphandle kokungenelela kwabantu. Izikhululo ze-LNG ezingasetyenziswanga zisisombululo esizinzileyo, ukubonelela ngokufutheka okusebenzayo ngelixa kuncitshiswa ukukhutshwa kwekhabhoni kunye negalelo kwinguqu kwimithombo yamandla acocekileyo.
