AMPP CP2 Technician study plan

Define the three NACE/AMPP protection criteria (100 mV polarization shift, -850 mV CSE with IR, 100 mV depolarization) in your own words and state when each applies

Set up a field-notes template that records structure-to-electrolyte potential, reference electrode type, location, and surface condition for every reading

Explain how half-cell placement, contact resistance, and soil resistivity bias a potential measurement

Differentiate native, depolarized, instant-off, and on-potentials and identify which one each criterion requires

Calculate IR-drop error contributions from pipeline coating, soil, and reference electrode placement in simple resistance models

Apply Ohm's law, series/parallel resistance, and Kirchhoff's laws to a coated-pipeline current-distribution example

Compute soil resistivity from a Wenner four-pin array and explain how resistivity drives current distribution and anode spacing

Design a close-interval survey interval and justify it from soil resistivity and coating condition

Explain polarization, depolarization, and the effect of coating holidays on current demand at a given structure

Size an impressed current rectifier (voltage and current) from groundbed resistance, structure-to-earth resistance, and current requirement

Compare anode material families (mixed metal oxide, graphite, high-silicon cast iron) by consumption rate and application

Compute groundbed resistance for vertical and horizontal anode configurations and explain the effect of coke breeze

Distinguish constant-voltage from constant-current rectifiers and interpret tap settings, stack voltage, and output readings

Diagnose common rectifier faults (blown fuse, open diode, AC ripple, groundbed failure) from meter readings

Compute galvanic anode output current from driving potential, circuit resistance, and anode-to-structure resistance

Select magnesium, zinc, or aluminum anodes based on electrolyte resistivity and structure coating quality

Size galvanic anode strings to meet a stated current requirement and design life using anode mass consumption and utilization factor

Calculate anode bed life and number of anodes needed for a given structure current demand

Explain how anode-to-electrolyte resistance and backfill affect output and how to test anode condition in the field

Apply series/parallel circuit analysis to multiple-anode installations sharing a common structure

Identify stray current sources (DC transit, welding, foreign pipelines, HVDC) and interpret potential-shift signatures on a structure

Perform a current-drainage and mitigation-bond calculation, including resistance-bond sizing and unidirectional drainage

List the safety requirements for rectifier work, confined-space groundbed entry, and energized AC/DC measurements

Write a lockout/tagout and personal protective equipment sequence for servicing an impressed current rectifier

Explain how coating type, holiday size, and disbondment change CP current demand and current distribution

Describe coating conductance testing and how to use it to prioritize rehabilitation

Relate shielding (disbonded coating, rock shield, casing) to underprotection and interference conditions

Evaluate interference risk and mitigation options for a cased crossing or a parallel foreign pipeline

Assemble and execute a full system commissioning and troubleshooting checklist covering rectifier, groundbed, test stations, and bonds

Re-derive all protection criteria and state the field evidence required to demonstrate each one

Resolve a set of mixed-domain troubleshooting scenarios under time pressure and justify each corrective action

Identify and close your three weakest objectives from the earlier weekly deliverables
