AQ, performs the cool down of lng fuel tanks


AQ performs the cool down of LNG fuel tanks. Before filling tanks with LNG, it is necessary to cool them down to -164°C. This happens with liquid nitrogen, which makes the temperature of the tanks drop about 10 degrees per hour. When the tanks have reached the desired temperature, they can be bunkered with LNG.
