Should bulk storage tanks be anchored?

Anchoring bulk storage tanks is an important safety consideration, particularly in preventing the tanks from becoming dislodged during extreme weather events or seismic activity. The statement that tanks should be anchored unless the tank liquid level is higher than the dike wall aligns with industry best practices for ensuring safety while also considering containment measures.

When the liquid level in a bulk storage tank is higher than the dike wall, the potential for the tank to float when inundated by water is reduced, as the dike is meant to contain any spill or leak that may occur. In such cases, if the surrounding water does not breach the dike and poses no risk of lifting the tank, anchoring may not be strictly necessary.

In scenarios where the liquid level does not exceed the dike wall, to maintain the integrity of the tank during storage and avoid any risks associated with potential floating or displacement, anchoring becomes crucial for ensuring stability and safety.

In summary, the correct reasoning highlights the relationship between tank stability, dike wall height, and safety protocols regarding anchoring, emphasizing the importance of site-specific considerations for bulk storage tanks.
