The oil tank area must do emergency work to prevent rainstorm to ensure the safety of the oil tank. Here are some safety protection measures for API 650 floating-roof tanks in heavy rain.

Combination of Design Loads
The inner tank API 650 floating-roof tanks shall be designed for the most critical combinations of loading that result from internal pressure and liquid head, the static insulation pressure, the insulation pressure as the inner tank expands after an in-service period, and the purging or operating pressure of the space between the inner and outer tank shells, unless the pressure is equalized on both sides of the inner tank.
