Itanki yobisis likhonkco elibalulekileyo kwikhonkco lonikezelo lobisi, liqinisekisa ukuba ubisi olutsha lufikelela kwizityalo ezilungisayo ukusuka kwiifama ngendlela ekhuselekileyo, esebenzayo, nangexesha elifanelekileyo. Ezi zithuthi zikhethekileyo ziyilelwe ukuthutha umthamo omkhulu wobisi ngelixa zigcina imigangatho engqongqo yezempilo ukugcina umgangatho walo. Ubungakanani kunye nokwakheka kweetanki zobisi zibalulekile kule nkqubo, ziphembelela ngokuthe ngqo amandla azo, ukusebenza kakuhle, kunye nokuthotyelwa kwemigaqo yendlela. Eli nqaku ligocagoca kwiinkcukacha ze ubisi itanki ubude, ukuphonononga izinto ezimisela ubungakanani bazo kunye nefuthe kushishino lobisi.

Ubude betanki yobisi buyahluka ngokuxhomekeke kuhlobo lwesithuthi kunye nemigaqo kwingingqi apho isebenza khona. Ngokomyinge, itanki yobisi kwi eunited States or iYurophu iphakathi kwe-40 kunye ne-53 yeenyawo ubude (malunga ne-12 ukuya kwi-16 yeemitha). Olu bude bubandakanya zombini iyunithi yetrektara, ehlala injini kunye nekhabhinethi yomqhubi kunye nenqwelwana, equlethe itanki yobisi.

Iyunithi yetrektara ngokuqhelekileyo ilinganisa phakathi kwe-15 ukuya kwi-20 iinyawo (4.5 ukuya kwi-6 yeemitha) ubude. Le nxalenye yesithuthi ibalulekile njengoko inika amandla afunekayo ukutsala umthwalo onzima. Ubungakanani beyunithi yetrektara bunokwahluka ngokusekwe kumvelisi kunye nemodeli, kunye noyilo oluthile olulungiselelwe ukusebenza kakuhle kwamafutha kunye nolunye amandla kunye nokuqina.

Inqwelo erhuqwayo, equlethe eyona tanki yobisi yokwenene, idla ngokulingana phakathi kweemitha ezingama-25 ukuya kwezi-40 (iimitha ezisi-7.5 ukuya kwezili-12). Ubude betreyila ubukhulu becala bunqunywe ngumthamo wayo, onokusuka kwi-5,000 ukuya kwi-8,000 iilitha (18,927 ukuya kwi-30,283 iilitha) zobisi. Iitreyila ezinkulu zisetyenziselwa ukuthutha uhambo olude okanye xa kusetyenzwa kwiifama ezinkulu zobisi, ngelixa iinqwelwana ezincinci zingasetyenziselwa imigama emifutshane okanye kwiindawo ezinezithintelo zendlela.

Ngelixa i-avareji tanker yobisi iwela ngaphakathi kwe-40 ukuya kwi-53-foot range, kukho ukuhluka okusekelwe kwiimfuno ezithile kunye nemimiselo yengingqi. Kwamanye amazwe, ngakumbi lawo anothungelwano olubanzi lweendlela kunye nezithintelo zobungakanani obungqongqo, iitanki zobisi zinokude nangakumbi. Umzekelo, kwi Ostreliya, iitanki zobisi zinokufikelela kubude obuziimitha ezingama-65 (malunga neemitha ezingama-20) xa usebenzisa indibaniselwano yeyunithi yetrektara kunye ne-semi-trailer.

Kwimimandla efana Ostreliya, Nyu Zilend, yaye iindawo zaseYurophu, ii-B-double tankers zisetyenziswa ngokuqhelekileyo. Ezi ziquka iyunithi yetrektara etsala iitreyila ezi-2 ezidityaniswe livili lesihlanu. Ubude obudityanisiweyo beetanki ze-B-double zingaba ziimitha ezingama-85 (iimitha ezingama-26). Ezi zithuthi zisebenza kakuhle kakhulu ekuthutheni umthamo omkhulu wobisi kwimigama emide, zinciphisa inani leehambo ezifunekayo kwaye ngaloo ndlela iindleko zokusebenza.

Ngokwahlukileyo koko, iitanki zobisi ezincinci zihlala zisetyenziswa kwiindawo zasezidolophini okanye kwimimandla eneendlela ezimxinwa kunye neekona ezixineneyo. Ezi tanki zinokuba mfutshane kangange 30 feet (9 metres) ukuqinisekisa ukuba ziyakwazi ukuhamba kwizitrato zedolophu okanye kwiindlela zasemaphandleni ezingalungelanga izithuthi ezinkulu. Ezi tanki zincinci zibalulekile ekuqokeleleni ubisi kwiifama ezikwiindawo ekunzima ukufikelela kuzo zize ziludlulisele kwiietanki ezinkulu kwiindawo zokuqokelelwa kwazo.

Zininzi izinto ezinefuthe kubude betanki yobisi, kubandakanywa nemigaqo, ubungakanani bomsebenzi wobisi, kunye nejografi yendawo esebenza kuyo itanki.

Amazwe ahlukeneyo kunye nemimandla inemimiselo ethile elawula ubungakanani kunye nobunzima bezithuthi ezivunyelwe kwiindlela zoluntu. Le migaqo yenzelwe ukuqinisekisa ukhuseleko ezindleleni, ukukhusela iziseko ezingundoqo, kunye nokunciphisa impembelelo yokusingqongileyo. Kwi eunited States, umzekelo, umthetho we-federal unciphisa ubude bezithuthi zorhwebo ukuya kwii-53 ezinyaweni kwiindlela ezihamba phambili, kodwa amazwe anokuba nezithintelo ezongezelelweyo. Kwi iYurophu, ubuninzi obuvunyelwe ubude be-semi-trailer ngokuqhelekileyo yi-16.5 yeemitha (malunga neenyawo ze-54), nangona oku kunokwahluka ngokwelizwe.

Ubude betanki yobisi buhambelana ngqo nomthamo wayo. Iifama ezinkulu zobisi okanye ookopolotyeni abavelisa umthamo omkhulu wobisi mihla le bafuna iitanki ezinomthamo omkhulu, ezithi nazo zifune iitreyila ezinde. Le mfuno ivakaliswa ngokukodwa kwimimandla enemveliso yobisi ebanzi, apho ukwandisa umthamo wobisi othuthwayo ngohambo ngalunye kubalulekile ekusebenzeni kakuhle.

Ijografi yommandla ikwadlala indima ebalulekileyo ekumiseleni ubungakanani beetanki zobisi. Kwiindawo ezineendawo ezivulekileyo ezibanzi kunye nemigama emide phakathi kweefama kunye nezityalo zokulungisa, ezifana ne Ostreliya okanye I-American Midwest, iinqanawa ezinde zixhaphakile. Le mimandla iyazuza kusetyenziso lwezithuthi ezikhulu ezinokugubungela imigama emikhulu ngaphandle kokufuna ukuphinda zilayishe okanye zifake amafutha rhoqo. Ngokwahlukileyo koko, kwiindawo ezinemihlaba ecela umngeni, njengemimandla yeentaba okanye iindawo ezineefama ezininzi ezincinci, ezimfutshane, iitanki ezinokulawuleka ziyakhethwa.

Ubude kunye nobukhulu beetanki zobisi zibalulekile ekusebenzeni kakuhle nasekugcinekeni kwekhonkco lonikezelo lobisi. Iitanki ezinkulu zinokuthwala ubisi oluninzi ngohambo ngalunye, zinciphisa inani lohambo olufunekayo kwaye ngaloo ndlela zehlise ukusetyenziswa kwamafutha kunye nokukhutshwayo. Oku kusebenza kakuhle kubalulekile kumxholo wanamhlanje wokunyuka kweendleko zamafutha kunye nokunyuka kokugxila ekunciphiseni i-carbon footprint yemisebenzi yezolimo.

Ngaphezu koko, ukukwazi ukuthutha umthamo omkhulu wobisi ngokukhawuleza kwaye ngokukhuselekileyo kubalulekile ukugcina ukutsha kunye nomgangatho wemveliso. Ubisi lunokonakala kakhulu, kwaye nakuphi na ukulibaziseka kwezothutho kunokukhokelela ekonakaleni. Ngokusebenzisa iitanki ezinobungakanani obufanelekileyo, iinkampani zobisi zinokuqinisekisa ukuba ubisi lusiwa kwiindawo ezilungisayo ngokukhawuleza, zigcina umgangatho walo kwaye zinciphisa inkunkuma.

Itanki yobisis ziyinxalenye ebalulekileyo yoshishino lobisi, kwaye ubukhulu bazo budlala indima ebalulekileyo ekusebenzeni kwabo ngokufanelekileyo. Ngelixa i-avareji yetanki yobisi iphakathi kwe-40 kunye ne-53 ubude beenyawo, iinguqu zikhona ukuze zihlangabezane neemfuno ezahlukeneyo kunye nemimiselo yengingqi. Ukuqonda izinto eziphembelela ubude beetanki zobisi kunceda ekuxabiseni indima yazo ekuqinisekiseni ukuba ubisi olutsha, olukumgangatho ophezulu lufikelela kubathengi kwihlabathi liphela. Njengoko ishishini lezobisi liqhubeka nokuvela, uyilo kunye nobukhulu beetanki zobisi buya kuziqhelanisa nokuhlangabezana nemiceli mngeni emitsha, ukuqinisekisa ukuba zihlala zilikhonkco elibalulekileyo kwikhonkco lokubonelela.
