Compared with the external floating roof API 650 anchored tanks, the internal floating roof API 650 anchored tanks has the advantages of protecting the floating roof from wind and rain and ensuring the quality of liquid storage under the floating roof. At the same time, because the inner floating plate is in the tank, there is no rain and snow load, so the central drainage pipe and escalator and other accessories on the floating plate can be omitted. In addition, under the same sealing conditions, the internal floating roof tank can further reduce the evaporation loss compared with the External floating roof tank.
API Standard 620 tank Appendix C describes the factors involved in obtaining adequate foundations for tanks that operate at atmospheric temperature. The foundations for refrigerated tanks are complicated because of the thermal movement of the tank, the insulation required for the bottom, the effects of foundation freezing and possible frost heaving, and the anchorage required to resist uplift. The services of a qualified foundation engineer are essential. Experience with tanks in the area may provide sufficient data, but normally a thorough investigation, including soil tests, would be required for proper design of the foundation.
