LNG Bunkering: Technical and Operational Advisory
One way to drain the bunker line is to allow the LNG to vaporize in the pipes while the valves leading to the ship''s fuel tank are left open. This allows the LNG and natural gas vapor to flow to the tank. Purge connections also can be used after bunkering to force the remaining LNG into the ship''s fuel tanks.
