The situation

What has happened

The 150 millimetre steel high pressure main between Morwell and Moe is protected by rectifier R-09 and monitored at 22 test points. Last year's survey recorded a 120 millivolt drift at TP-14 that was noted but never investigated. A new housing estate has been built beside the main since then and a telecommunications duct was installed across the easement in July. Work order WO-26-3315 schedules the survey for 15 September. Tom Halloran wants every reading recorded against the asset, every defect raised, and a technical report he can table at the safety case review. The reference electrode and multimeter calibration certificates are in the depot store.

Your brief. Plan and carry out the survey to the cathodic protection procedure, record and assess the readings, raise work orders for defects, and compile a technical report with clear recommendations for the Maintenance and Integrity Manager.

What to look for

Evidence guide

Check that readings carry units, dates and instrument identifiers, that the student recognises a drift within criteria as still needing investigation, and that the report separates observations from conclusions. Recommendations must name a role and a date. The work order for TP-14 must describe a safe excavation and coating inspection, not just say investigate.

The student's evidence summary lists every record they created or changed in the systems named above, their notes and the tasks they ticked. Verify it against the deliverables and your own assessment tool.
