Question 100Safety & Environmental - Assistant Engineer

The correct answer is C) the loading of new cargo into a decanted slop tank as a procedure to minimize pollution. The "load on top" method is a procedure used on crude oil carriers to minimize pollution during cargo operations. It involves loading new cargo on top of the remaining residues (slops) in a dedicated slop tank, rather than discharging the slops separately. This helps reduce the amount of oily water that would need to be offloaded and disposed of, thereby minimizing the environmental impact of the cargo operations. The other answer choices are incorrect because they do not accurately describe the purpose of the "load on top" method. It is not used for calculating ullage, cargo expansion ratios, or loading ballast by gravity.
