🔍 Key Concepts

• LNG carrier safety systems and where gas detection is most critical • Purpose of methane gas detectors on gas carriers • Spaces where methane may accumulate if a leak occurs

💭 Think About

• In which locations on an LNG carrier could a methane leak create an invisible, highly flammable gas cloud? • Are gas detection systems usually limited to one specific area, or installed anywhere methane could reasonably leak or accumulate? • Think about both cargo-related spaces and machinery spaces that handle gas as fuel or boil-off gas.

✅ Before You Answer

• Identify all spaces listed that contain methane or methane piping during normal operations • Consider SOLAS and IGC Code intent: to detect gas leaks before they reach dangerous levels • Check whether detection is usually installed only in cargo areas, only on fuel lines, or in any enclosed space where gas could be present
