Lub tank ntawm cov roj tank tsheb yog nyob deb ntawm ib qho yooj yim khoob chim; nws cov qauv sab hauv suav nrog cov txheej txheem ntawm cov qauv tsim qauv tsim tshwj xeeb los tiv thaiv lub zog muaj zog ntawm cov khoom ua kua thaum lub sijhawm tsav tsheb. Qhov kev sib tw tseem ceeb yog txhawm rau txhawm rau "kua surge." Qhov kev nce siab no tuaj yeem ua rau muaj kev cuam tshuam loj heev uas cuam tshuam rau lub tsheb kev ruaj ntseg thiab tuav, tshwj xeeb tshaj yog thaum lub sij hawm acceleration, braking, thiab cornering. Kev sloshing hnyav tuaj yeem ua rau muaj kev sib tw. Lub hauv paus txheej txheem siv los daws qhov teeb meem no yog baffle.
Baffles yog ib tug series ntawm perforated steel daim hlau welded rau lub puab phab ntsa ntawm lub tank, faib tag nrho cov loj ntim rau hauv ob peb me me, interconnected compartments. Cov phiaj no ua haujlwm zoo ib yam li ballast hauv lub nkoj thaum muaj cua daj cua dub; lawv ua kom muaj kev tiv thaiv rau cov kua ntws, cuam tshuam qhov tsim ntawm cov nthwv dej loj. Thaum lub tsheb nres, cov kua rushing mus rau pem hauv ntej lub taub hau yog zoo thaiv thiab dispersed los ntawm cov thawj baffle, nrog rau nws cov kev cuam tshuam quab yuam yog zuj zus dissipated. Ib yam li ntawd, lateral sloshing thaum lem yog suppressed los ntawm longitudinally baffles. Cov tswv yim tsim qhov hauv cov baffles tso cai rau cov kua kom dhau los ntawm maj mam thiab tsis tu ncua thaum thauj khoom thiab tshem tawm thaum tswj hwm lawv cov haujlwm tseem ceeb ntawm surge suppression. Tsis tas li ntawd, tus ntoo khaub lig- ntu cov duab ntawm lub tanker yog ua tib zoo tsim. Cov duab zoo li oval lossis ncig yog nyiam dua cov duab plaub vim tias lawv zoo dua faib cov quab yuam raws li tensile stresses hla tag nrho cov qauv tank, tsis txhob muaj kev ntxhov siab. Hauv qab ntawm lub tank feem ntau yog tsim nrog lub sump thiab yog me ntsis sloped ntawm lub qhov hluav taws xob tawm. Qhov no ua kom tiav cov kua dej thaum lub sij hawm tshem tawm, txo cov khoom seem thiab kev pheej hmoo ntawm kev sib xyaw cov khoom sib txawv. Rau cov roj tsheb thauj khoom nqa ntau yam khoom sib txawv, lub tank sab hauv tuaj yeem muab faib ua ntau qhov sib cais. Txhua lub compartment muaj nws tus kheej filling thiab tso tawm manifold. Qhov kev tsim no tso cai rau ib lub tsheb thauj mus los sib txawv ntawm cov khoom ib txhij, ua tiav kev thauj mus los zoo thaum tiv thaiv kev sib kis ntawm cov khoom sib txawv. Ua ke, cov kev tsim qauv sab hauv no hloov pauv qhov muaj peev xwm txaus ntshai dynamic system mus rau hauv ib qho chaw ruaj khov thiab tswj tau kev thauj mus los.
