Q

There is a water spray or deluge system on LNG vessels that provide a water spray over all areas around the cargo system. The system can be used for __________.

🔍 Key Concepts

• Role of water spray/deluge systems on LNG carriers • Effects of LNG leaks on steel structure (extreme cold, possible brittle fracture) • Purpose of water spray in reducing radiant heat from a fire

💭 Think About

• Ask yourself what hazards an LNG water deluge system is mainly designed to control: heat from fire, cold from leaks, or something else? • Consider how water interacts with very cold LNG spills and with hot fires—does it help more with cooling hot surfaces, warming cold surfaces, or shielding from heat? • Think about whether the same system could reasonably serve more than one protective purpose, based on how it operates.

✅ Before You Answer

• Verify how radiant heat shielding is usually provided on LNG carriers (is water spray one method?). • Recall how mild steel behaves at cryogenic temperatures and whether water spray can mitigate that effect. • Check whether the deluge system is described as multi-purpose (fire protection and structural protection) in standard LNG safety guidance.
