Which factor must be considered when determining the order of loading of dissimilar products through the same piping system aboard a tanker?

Correct Answer: Option A — Contamination of the cargo

Cargo sequencing in shared piping systems is critical to prevent cross-contamination. Per 46 CFR, the sequence must ensure that incompatible products do not mix. Operators must plan the loading order to maintain product purity, often utilizing line displacement or pigging procedures to clear lines between dissimilar grades.
