🔍 Key Concepts

• Inert gas system purpose – what it is designed to prevent inside cargo tanks on tankers • Source of inert gas on many crude oil tankers (think about where large amounts of exhaust gas are produced) • Typical composition of inert gas and whether noble gases like helium are practical or economical for shipboard use

💭 Think About

• Ask yourself: What is the main safety function of an inert gas system in a tank vessel’s cargo tanks? Would that function increase or decrease rusting? • Consider which shipboard system continuously produces large volumes of gas with very low oxygen content that can be reused rather than wasted. • Think about cost and availability: Is helium commonly carried in the huge quantities needed to blanket cargo tanks, or is there a more obvious gas source already available on the ship?

✅ Before You Answer

• Verify which common shipboard exhaust stream is often cleaned and cooled to become inert gas for cargo tanks. • Check whether oxygen content in inert gas is high or low, and how that affects corrosion (rusting) in steel tanks. • Confirm from basic engineering knowledge whether large-scale use of helium is realistic on commercial tankers compared to flue gas from boilers.
