This unit involves the skills and knowledge required to maintain cathodic protection systems to prevent corrosion of steel gas pipelines.

It includes identifying the type and location of the cathodic protection fault, using the correct electrical equipment, maintaining and adjusting cathodic protection system and equipment, re-establishing the system and completing relevant documentation.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Range is restricted to essential operating conditions and any other variables essential to the work environment. Non-essential conditions may be found in the UEG Gas Industry Training Package Companion Volume Implementation Guide.
types of faults must include at least eight (8) of the following:	coating damage/deterioration interference from other systems anode not working equipment fault/failure earth faults transformer failure anode bed deterioration anode cable failure telluric effects on cathodic protection systems isolated/insulation joint (IJ) failure and testing flange insulation kit (FIK) failure and testing
checks and tests on cathodic protection systems must include at least four (4) of the following:	cathodic protection potential surveys on/off potential surveys coating defect assessment surveys (direct current voltage gradient (DCVG) method, Pearson technique/method, over pipeline potential method) loop impedance testing anode bed testing soil resistivity testing interference testing trad unit commissioning and testing

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist
