One way to protect tanks from high wind loads is by:

Securing tanks with metal bands is an effective method to protect them from high wind loads. Metal bands help to stabilize the tank in high winds by providing additional support and structural integrity. They work by placing tension around the tank, reducing the risk of it being toppled or experiencing structural failure, especially in situations where wind forces might exceed the tank's design limits.

The application of metal bands serves to reinforce the external structure, ensuring that it can withstand lateral forces exerted by strong winds. This approach is particularly relevant for above-ground tanks, where external forces from wind can be significant due to their large surface area.

The other methods mentioned do not directly address protection against wind loads as effectively. For instance, insulating tanks is generally focused on temperature control rather than structural stability in high winds. Reducing the height of the tank could potentially mitigate some wind loading effects, but it might not be practical or sufficient for larger tanks. Securing tanks underground may offer protection from various external forces, but it is typically impractical for certain types of tanks, especially those designed for easy access or where underground placement is not feasible.
