🔍 Key Concepts

• 33 CFR Part 155 – Oil or Hazardous Material Pollution Prevention Regulations • Definition and intent of “prohibited oil spaces” (what areas are meant to be protected from oil contamination if damaged) • Typical locations on a ship that are most vulnerable to grounding or collision damage

💭 Think About

• Think about which parts of the vessel are most likely to be damaged first in a collision or grounding and why regulations would keep oil out of those areas. • Consider whether the regulations are more concerned with side tanks, midship tanks, or end compartments of the vessel. • Ask: If this part of the ship is breached, would oil there be especially likely to escape into the water quickly?

✅ Before You Answer

• Look up how 33 CFR Part 155 defines or describes prohibited oil spaces and which ship locations it names specifically. • Check whether the rule talks about forepeak versus afterpeak compartments, or about midship or double-bottom locations. • Verify which of the listed tank locations is explicitly mentioned in the regulatory language as a prohibited place for oil tanks.
