Abstract: An exemplary bilobe or multilobe tank for storing liquefied natural gas includes at least two tank sections, each tank section having a curved upper surface and curved bottom surface, the tank sections being joined to each other so that the tank has an undulating upper surface and an undulating lower surface. Each tank section is connected to an adjacent tank section with at least one connecting duct so that a horizontal flow path is formed between the lowermost points of the adjacent tank sections or between the uppermost points of the adjacent tank sections.
