Question 55Safety & Environmental - QMED70% to pass
Water ballast placed in a tank that has been crude oil washed, but not water rinsed, shall be regarded as _______________.
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.
