Prevention of LNG roll-over in an LNG tank.
Author(s) : TAMURA M., NAKAMURA Y., IWAMOTO H.
Summary
When new LNG (in cargo) enters a tank partially filled with another LNG (inventory), and the two LNGs are not fully mixed, an LNG stratified layer appears in the tank because of the slightly different densities of the two LNGs. LNG stratification in a tank causes a roll-over phenomenon that produces an almost spontaneous boil-off of large amounts of methane vapour. It is important to fully mix cargo and inventory to prevent LNG stratification in order to prevent LNG roll-over in the tank.
