🔍 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
