🔍 Key Concepts

• Ro-Ro (Roll-on/Roll-off) vessel cargo operations sequence • Purpose of a stern door and ramp on a Ro-Ro ship • Meaning and use of a red cargo light on cargo vessels

💭 Think About

• Which of these actions logically happens before you can even lower a stern ramp, and which could happen after? • Which option is clearly related to tanker or pump room operations, not Ro-Ro ramp operations? • Think about how other traffic and nearby vessels are warned that cargo operations involving vehicle movement are about to start.

✅ Before You Answer

• Eliminate any choice that is specific to tankers/pump rooms, since this is a Ro-Ro ramp question. • Ask yourself: can you lower a stern ramp if the stern door is still shut? If not, when would that door have been operated? • Consider which action most directly signals or prepares for loading/discharging operations once the ramp is down and before vehicles/cargo start moving.
