🔍 Key Concepts

• Cofferdam as used in ship construction and tankers • Purpose of spaces between two liquid-containing compartments • How ships prevent leaks from one tank contaminating another or the sea

💭 Think About

• Ask yourself: Is a cofferdam usually filled with something or is it intentionally left empty/void? • Which option describes a space whose main job is protection and separation, not storage? • Think about where you would place a cofferdam on a tanker that carries fuel or chemicals—what is it trying to keep apart?

✅ Before You Answer

• Check which choices describe a space versus a tank used for storage. • Eliminate any option where the space has a permanent cargo or liquid in it. • Focus on the answer that mentions separating compartments and leakage protection, since that is the main function of a cofferdam.
