Q

The deck water seal of the inert gas system __________.

🔍 Key Concepts

• Inert gas system layout – where the deck water seal is located in the system (between the cargo tanks and the machinery space). • Backflow protection vs. pressure control – which components are used to stop gases flowing backward, and which control overpressure/underpressure. • Other IGS components – scrubber, fans/blowers, deck isolating valve, P/V breaker and their primary functions.

💭 Think About

• First, picture the path of inert gas from the flue gas source to the cargo tanks; ask yourself: what would happen if tank gas tried to flow backward toward the engine room? • Which piece of equipment in an inert gas system is specifically designed to deal with heat and soot, and which to deal with pressure surges? • Look at each option and match it to the most likely component: which job sounds like a scrubber, which like a pressure/vacuum breaker, and which like a non‑return/backflow device?

✅ Before You Answer

• Identify which component primarily cools and washes the flue gas (this is usually not the deck water seal). • Identify which component is primarily for overpressure/vacuum relief of the cargo tanks (often a P/V breaker or similar, not the water seal). • Confirm which device in the system is described in texts as a non‑return or backflow prevention device located at the deck between hazardous and nonhazardous areas.
