On a tanker, the furthest aft and centerline tank would most likely be designated as the:

• A. Slop Tank
• B. Fore Tank
• C. Cargo Tank
• D. Ballast Tank

Answer: (A)

On a tanker, how a tank is designated depends on its location and its function. The furthest aft tank that sits on the centerline is typically the slop tank. This tank is intended to hold oily water, washings, and cargo residues collected during cargo operations. Placing it at the extreme stern along the centerline makes drainage from other cargo tanks into a single, centralized receptacle easier and keeps these residues away from the main cargo spaces. It also aligns with the ship’s processing setup, where the slop contents can be directed to separators or treatment systems. The other options don’t fit this specific location and purpose as well. A forward tank is at the front, not the aft. Cargo tanks are the primary spaces used to carry product and aren’t defined by being at the stern centerline. Ballast tanks hold ballast water and are located where ballast distribution is needed, not designated by being the aft centerline tank.
