Ullage and Sounding


Our experts also determine the weight of cargo by such methods as measuring voids (Ullage) and measuring depths (Sounding). When measuring voids, the amount of cargo is calculated from the unfilled part of cargo tanks (holds), the measurement takes place from the top of the tank to the top of the liquid. Sounding – inspection of the amount of cargo by the method of depth measurement is performed to determine the depth of the liquid in the tank by measuring from the surface of the liquid to a certain reference point in the lower part of the tank.
