LNG carrier Wikipedia
A typical LNG carrier has four to six tanks located along the center line of the vessel. Surrounding the tanks is a combination of ballast tanks, cofferdams and voids; in effect, this gives the vessel a double hull type design. Inside each tank there are typically three submerged pumps.
Common Tank Gauging Technologies and How They Work Varec
Two types of measurement methods are used for tank gauging: volume or mass based. In a volume based system, level is measured. In a mass based system, the measurement of the hydrostatic pressure of the liquid column is used. The users choice should, therefore, be based on how product inventory is calculated and accounted via volume or weight.
