🔍 Key Concepts
• Cofferdam as used in tankers and liquid cargo vessels
• Purpose of spaces between cargo tanks and other compartments
• Difference between cargo containment and separation/protection spaces
💭 Think About
• Ask yourself: Is a cofferdam a place where cargo is carried, or a space that should remain empty?
• Which option best describes a feature that protects against leakage or heat transfer between two tanks or spaces?
• Think about why regulations require special separation between fuel or cargo tanks and machinery or accommodation spaces.
✅ Before You Answer
• Verify that a cofferdam is normally kept dry and free of cargo or ballast
• Check which choice mentions a void or empty space rather than an opening, tube, or loading area
• Confirm that a cofferdam’s main role is separation and safety, not measurement, cleaning, or loading
