Is work pressure the same as hydrostatic pressure?

Design pressure: Atmospheric pressure. Calculated pressure: 0.15
It means that the device is only subjected to hydrostatic pressure.

At least 1.15 times the operating pressure, or the pressure value under the most severe coupling conditions (temperature and pressure)!
Brother hasn’t studied containers yet; he thinks that the working pressure of a container should equal the gas phase pressure plus the liquid phase pressure
Working pressure is the pressure at the top of the container equipment; therefore, the design pressure can be expressed as a slight positive pressure or atmospheric pressure； Some say that 0.15 should be used directly as the working pressure for equipment design; that is, 0.15*1.1=0.165, resulting in a design pressure of 0.17 MPa. Which of these two methods is closer to the standard definition?
Does that work pressure include the hydrostatic pressure of the liquid column?
