🔍 Key Concepts

• Grounding damage can occur anywhere along the hull where tanks are located • Any tank (whether full, slack, or empty) can show evidence of holing or flooding • Purpose of sounding: detect unexpected change in level of water, fuel, or ballast

💭 Think About

• If a tank was believed to be empty before grounding, what would sounding it tell you afterward? • How could a hole in a tank that is full be detected by sounding, and why might that be important for stability and pollution? • When you are unsure where the damage is, is it safer to limit checks to certain tanks, or to assume any area near the grounding could be compromised?

✅ Before You Answer

• Verify which condition of tank (full, slack, or empty) would not be able to take on water or lose contents if holed • Consider that damage location is uncertain in a grounding, so think about whether selective or comprehensive sounding is safer • Remember that the aim of sounding is to detect any abnormal level change, regardless of what was originally in the tank
