An oceangoing ship of 350 gross tons, constructed in January 1976, and not equipped with an oily water separator, may retain all bilge slops __________.
• 33 CFR MARPOL-related pollution prevention requirements for oceangoing ships of 100 gross tons and above • Purpose and definition of bilge slops and where they may safely be retained if no oily water separator is fitted • Structural spaces on a ship: bilges, tanks, cofferdams, and their intended functions
• Which option names a space that is specifically intended or acceptable for storing contaminated liquids like oily bilge water on a continuing basis? • For each choice, ask: Is this space normally part of the ship’s pollution control/holding system, or is it meant for some other primary purpose (buoyancy, separation, safety isolation)? • Think about stability and safety: Would holding large quantities of bilge slops in this location be consistent with normal ship design and regulations?
• Verify which listed space is normally used as a designated holding tank for oily mixtures if discharge is not allowed • Eliminate any option whose primary purpose is structural separation or safety isolation, not liquid storage • Consider whether the regulations allow indefinite retention of oily mixtures in a space that is open to the hull’s structure and not a closed, controlled tank
