API 12D vs 650 Tank Design- Anchorage Requirements

[Soln]

API 650 Tank in Colorado, 40'Dia X 24', with 3.5 oz/in^2 requires overturning anchorage. On the other hand, API 12D tank, equal size, equal pressure, same location- I don't see any 12D reference to wind design, seismic design, or anchorage requirements. Am I missing something? How is it justified- equal tanks, one 650 requires anchorage, one 12D no anchorage required?

Okay, thanks for the heads-up. Can you describe how to link?
