Cargo system on crude oil tankers

Tankeri za prijevoz sirove nafte su jedni od najvećih brodova koji plove svim svjetskim morima. U radu se navode glavni sustavi bez kojih tanker ne bi mogao vršiti ono za što je konstruiran, a to je prijevoz tekućeg tereta. U današnje vrijeme tankeri se grade po uzdužnom sustavu gradnje koji se je pokazao najboljim rješenjem. Ova vrsta tankera za glavne pumpe tereta koristi centrifugalne pumpe koje su najčešće pogonjene parnom turbinom. Najvažniji sustav na tankerima je sustav inertnog plina koji je neophodan za siguran rad tankera. Kao inertni plin na tankerima za prijevoz sirove nafte se obično koriste ispušni plinovi parnih kotlova zbog niskog udjela kisika. Zbog prirode tereta kojeg prevoze, na tankerima se posebna pažnja posvećuje sigurnosti kako bi se što je više moguće smanjio broj nezgoda.Crude oil tankers are one of the biggest vessels which navigate all world seas. This paper states main systems without which tanker could not perform for what it is designed, and that is transportation of liquid cargo. Nowadays tankers are built in longitudinal construction system which had been shown as best solution. This type of tankers uses centrifugal pumps as main cargo pumps, in most cases pumps are driven by steam turbine. The most important system on tankers is inert gas system which is required for safe operation of tanker. As inert gas on crude oil tankers are usually used exhaust gases from steam boilers due to low oxygen level. Because of nature of cargo which they carry, special attention is given to safety on tankers in order to decrease number of accidents
