  • Tanks lp/hp protection
















































Životinjska i biljna ulja i masti (pranje NaOH ili KOH – tankovi od SS ili EP – obavezno ispiranje toplom vodom)

  • Životinjska i biljna ulja i masti (pranje NaOH ili KOH – tankovi od SS ili EP – obavezno ispiranje toplom vodom)

  • Mineralna ulja (mješavina vode, deterđenta, emulgatora i sintetičkih sapuna, nekad kao dodatak i bazni benzin – obavezno ispiranje vodom zbog CH)

  • Petrokemijski proizvodi i druge otopine (kod tereta s niskim rosištem – isparavanjem / kod tereta s rosištem preko 100oC pom. petrokemijskih solvenata, tople vode i pare)



Animal and vegetable oils and fats (washing with NaOH or KOH – SS tanks or EP (epoxy coated) - mandatory rinse with warm water)

  • Animal and vegetable oils and fats (washing with NaOH or KOH – SS tanks or EP (epoxy coated) - mandatory rinse with warm water)

  • Mineral oils (washing with a mixture of water, detergents, emulsifiers and synthetic soap, sometimes a supplement of base gasoline should be used – FW rinsing is obligatory because of HC

  • Petrochemical products and other solutions (for a cargoes with a low dew point - evaporation - cargoes with a dew point over 100 °C should be washed with petrochemical solvents, hot water and steam)





Tank je opasan i nekoliko sati (dana) nakon pranja

  • Tank je opasan i nekoliko sati (dana) nakon pranja

  • Check lista prije ulaza u tank

  • Dodavanje aditiva-emulgatora za lakše pranje i održavanje kvalitete tereta

  • Paziti na kompatibilnost aditiva, te materijala tankova i opreme s kemikalijama

  • Balastiranje zabranjeno kod nekih tereta dok se kompletno ne iskrca tank tereta s kojim je balastni tank u dodiru (H2SO4, HCl, HNO3, H3PO4, i sl)

  • Odlaganje ostataka u slop-ove (3 stupnja)

  • Fenol zahtijeva konstantnu temp. Od 45-55 (uz aditiv do 60oC) – konstantna recirkulacija i ne prekidati iskrcaj (nitko na brod i nitko s broda)



Cargo tank is dangerous several hours (days) after washing

  • Cargo tank is dangerous several hours (days) after washing

  • Before cargo tank entering the check list is obligatory – signed by officer in charge

  • The aditives – emulgators are added into cargoes for easiest washing and cargo quality remaining

  • Pay attention on Cargo tanks matherials and other equipment compatibilities with additives

  • The ballasting of ballast tank which is in border with cargo tank is forbiden in the case of higly reactive cargo with sea water (H2SO4, HCl, HNO3, H3PO4, etc.)

  • Cargo tank washing residues must be transfered to sloop tanks (3 stupnja)

  • Fenol (for example) requires the constant temperatures of 45-55 (60oC if additive is added) – constant recirculation during unloading and discharging must not be interupted



Pumpe hidraulike (Hydro_pumps - Power Pack) – driven by el. motor or diesel motor

  • Pumpe hidraulike (Hydro_pumps - Power Pack) – driven by el. motor or diesel motor

  • Razvod na pumpe tereta i ostale uređaje (Hydraulic oil distribution to cargo pumps and other hydraulic equipment)

  • Tlačni cjevovod (Pressure Pipes - 200 bar)

  • Povratni vod (Return Pipes - cca. 3 bar)

  • Power Pack qapacity determine the total unloading capacity rate







Jednostepene ili višestepene – single or multistages

  • Jednostepene ili višestepene – single or multistages

  • Uronjena pumpa s dugom osovinom (deepwell pump) – el. mot. or hydromotor on the deck connected with the pump w. long shaft

  • (submersiblle) – hydromotor or el. motor together with the pump into tank

  • Prijenosna uronjena pumpa – portable submersible pump
