The decision of HPCL with respect to the design of the CP system shall be final and binding on the contractor. Theimpressedcurrentcathodicprotectionsystemshouldprovideauniform cathodic current density to the target bullet structure in order to maintain the steel atapotentialbetween-0.85Vand-1.5VrelativetoaCu/ CuS04reference electrode. Steel potential needs to be greater than -0.85 V to avoid corrosion and less than -1.5V to avoid excessive hydrogen evolution which Induces hydrogen embitterment ofhighcarbonsteelsusedinthefabricationofbullettanks.Theprotected structure thus needs to be maintained within a narrow window of 0.65V. ThetypeofAnodeanditspositioningrelativetothebullettankhasacritical influenceonbothachievingtheuniformcurrentdensityandmaintainingthe potential of the structure within the -0.85 V to -1.5 V potential range.In addition, the relative positions of the associated pipes and tanks have to be considered. 2.0DESIGN BASIS For designing the system, the following parameters should be considered: 1.Soil Resistivity - Min 10,000 ohm-cm (*) 2.
