Assessment Tasks

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.
