What is the purpose of insulation space purging with Nitrogen on membrane LNG carriers?
Direct Answer
Option A: Maintain inert atmosphere and monitor for gas leakage across primary and secondary barriers
Membrane LNG carriers utilize nitrogen in the insulation space to maintain an inert atmosphere, preventing combustion. This space is continuously monitored for methane leakage across primary and secondary barriers, serving as a vital safety feature mandated by the IGC Code to detect containment system degradation early.
