Because there is less sloshing, shipbuilders can also eliminate two corners of the octagonal shape and thus have right angles at the top of the tank. This means that about 5 percent more LNG can be stored and the production cost can be saved in the simplified tank shape, BASF says.
The blanket also lowers the boil-off rate, or vaporization, thus improving safety and increasing the amount of liquefied gas that arrives at the harbor.
