Iigiya ezinkulu zenziwe ngophindwe kabini zidlala indima ebaluleke kakhulu kwizicelo zaselwandle, zifundisa ukusebenza kakuhle kunye nokuqina kwiinkqubo ezahlukeneyo zaselwandle. Ezi girs zibonakaliswa ngamazinyo abo anjenge-engled, ezivumela ukubandakanyeka okucocwa kwaye kuncitshiswe ingxolo, ibetha ukuba ilungele imeko yaselwandle apho ukuthembeka kubalulekile.

Olunye usetyenziso oluphambili lweegiya ezinkulu ezazibhalwe ngesandla kwishishini zaselwandle zikwiinkqubo ze-propulsoon. Zisetyenziswa kwiibhokisi zeenqanawa kunye neenqanawa eziphantsi, ziguqulela amandla enjini ukuya kumandla afunekayo ukuba kuqhutywa iinqanawa ngamanzi. Isakhono seegiya esichetyiweyo ukuphatha imithwalo ephezulu ngelixa ugcina i-goonenty egudileyo iphucula intsebenzo kunye nokuthembeka kwezi ndawo zaselwandle.

Ukongeza, iigiya ezinkulu zenziwe ngesiphithiphithi zihlala zifumaneka kwizikhephe kunye neengcali, zibalulekile kwimisebenzi yokuphumla kunye nokuphatha impahla. Uyilo lwabo lombala luqinisekisa ukuba banokulawula imithwalo enzima kwaye baxhathisa, nto leyo ibalulekileyo kwiimeko ezinzima. Oku kuthembeka kunciphisa ixesha lokuphumla kunye neendleko zokugcina, zibenza babe ngabakhethiweyo kubakhi beenqanawa kunye nabaqhubi.

Kwimeko yokuntywila kwe-rigshore rigs, iigigi ezinkulu ze-helical zibalulekile oomatshini abahlukeneyo, kubandakanya ukuqhuba kunye nezixhobo zokuphakamisa. Ukusebenza kwazo kunceda ukwenzela inkqubo yokukhutshwa, ukuqinisekisa ukuba ukusetyenziswa kwamandla kuncitshiswa ngelixa kunyusa iziphumo.

Ngokubanzi, iigiya ezinkulu ze-heliling zibalulekile kwishishini laselwandle, ezinikezela amandla, ukusebenza kakuhle kunye nobomi obude. Njengokuba iteknoloji inkqubela phambili, indima yabo inokuthi yandise imisebenzi ye-marine kunye negalelo kwi-SARED, isebenza kakuhle ngakumbi.
