Software can be used to calculate the amplitude of the oscillations, but this is on the assumption that the effect of the floating platform is not taken into account; personally, I think the oscillations should decrease when the floating platform is included. If the design liquid level is determined based on the theoretically calculated wave height of oscillations, it leads to significant waste of volume; for example, in a tank with a capacity of 100,000 cubic meters, if the calculated wave height is 2.5 meters, it means that the upper part of the tank walls remains unused. Let’s all discuss this together; it would be great if there are standards or other calculation methods to support it. Thank you.
Refer to pages 4 and 21 of SH/T3007-2014
Thank you for your reference. This standard you provided doesn’t explain either the relationship between the design liquid level and the amplitude of the oscillation waves.
