After the tanks have been warmed up, the LNG Vapor is displaced with Inert Gas 💭.
Inert gas from Inert Gas Generator IGG is introduced to the tanks from the ⬇ bottom of the loading lines. The displaced LNG vapor is vented from the top ⬆ of the tank via the forward mast riser, or ashore if the ship is in port.
The inerting operation will continue until the hydrocarbon 🔥 content in the tank is reduced to 1.5 % by volume .
The operation takes about 20 hours 🕔.
