Question 55Safety & Environmental - QMED
70% to passWater ballast placed in a tank that has been crude oil washed, but not water rinsed, shall be regarded as _______________.
Asegregated ballast
Bdirty ballast
Ccrude oil
Dclean ballast
AI Explanation
The correct answer is B) dirty ballast. Water ballast placed in a tank that has been crude oil washed, but not water rinsed, shall be regarded as dirty ballast. This is because the tank has not been properly cleaned and decontaminated after the crude oil washing process. The remaining crude oil residues in the tank would contaminate the ballast water, making it unsuitable for discharge without proper treatment. The other options are incorrect because segregated ballast refers to ballast not contaminated by oil, clean ballast is ballast that has been properly cleaned, and crude oil is the liquid cargo itself, not the ballast.
