Question 115Safety & Environmental - Assistant Engineer
70% to passWhen tanks have been washed with crude oil, and ballasted without being water rinsed, the ballast is referred to as _______________.
Aclean ballast
Bdirty ballast
Csegregated ballast
Ddedicated ballast
AI Explanation
The correct answer is B) dirty ballast. When tanks have been washed with crude oil and then ballasted without being water rinsed, the resulting ballast water is considered "dirty ballast" because it is contaminated with the residual oil from the tank washing. This dirty ballast must be handled and disposed of properly to prevent oil pollution. The other options are incorrect: A) clean ballast refers to ballast that has been properly rinsed and is free of oil contamination; C) segregated ballast is clean ballast that is kept separate from cargo or fuel tanks; and D) dedicated ballast is ballast water that is used solely for stability and is not used for any other purpose.
