Contingency on Sacrificial Anode

[JohnLL]

I need a figure how much contingency should be considered when issuing the requisition for sacrificial anodes for offshore pipeline?
does a 10% contingency would cover all spares and contingencies due to any damage or loss?
what is the typical value for that in the industry?

thanks

10% should do it.
