Which method is used to supply inert gas from a flue gas system to the cargo tanks?

🔍 Key Concepts

• Inert Gas Systems (IGS) on tankers and how they use boiler or main engine uptake gases • How flue gas pressure is controlled and delivered to deck main and cargo tanks • Difference between moving gas by pressure vs. by fans or compressors in a flue-gas-based IGS

💭 Think About

• Think about what already provides pressure in a flue gas system before any extra machinery is added • Ask yourself: does a standard flue-gas IGS normally rely on additional compression, or does it mainly condition (clean, cool, dry) and then use existing pressure? • Consider which option would be simplest and most common on conventional crude oil tankers using boiler uptake gas as inert gas

✅ Before You Answer

• Check how the inert gas main is usually supplied on SOLAS crude oil tankers that use boiler uptake gas • Verify whether natural aspiration alone can overcome piping resistance and tank pressure settings • Ask: is a separate compressor normally fitted for flue-gas IGS, or is there another built‑in source of pressure?
