🔍 Key Concepts

• Emergency shutdown sequence during cargo loading • Who has immediate control of the cargo flow (ship vs. shore) • Purpose and effect of relief valves on cargo pumps

💭 Think About

• If a cargo valve jams open, what is the most direct way to quickly stop or reduce cargo flow? • Who can actually stop the cargo entering the system the fastest in this specific situation? • What is the difference between controlling the pump, controlling the valves, and calling supervision?

✅ Before You Answer

• Identify who can actually close or stop the source of pressure/flow right away • Consider which action directly affects cargo movement versus which only notifies someone or prepares for fire response • Think about whether a relief valve stops flow or just diverts pressure and what that means with a jammed-open cargo valve
