With regards to a ballast system associated with an oil tanker, what is meant by the term "segregated" ballast?

Correct Answer: Option B — Segregated ballast is dedicated clean ballast water introduced into tanks that are completely separate from cargo or fuel oil systems.

Segregated ballast systems are required by MARPOL and 46 CFR to prevent oil pollution. These tanks are physically isolated from cargo and fuel systems, ensuring that the ballast water remains clean and free of hydrocarbons, allowing for safe discharge into the marine environment without violating environmental protection regulations.
