Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

  5. Communicate with other personnel at site according to work requirements and confirm briefings and handover details are communicated and received
  6. Select equipment, tools and equipment required to carry out tasks, check for serviceability and rectify or report any faults within scope of own role
  7. Check restraining devices on all pressure hoses
  8. Fit and replace restraining devices on pressure hoses as required
  9. Raise alarm and report as required
  10. Position the crane hook to the centre of the storage reel
  11. Hoist the storage reel over the centre of the carrier and lower into saddles
  12. Lock down the storage reel with retainer brackets and set tension screws
  13. Install circulating equipment

  15. Line up saddles and cut excess coil tubing on rig floor with casing cutter
  16. Align saddles to remove storage reel
  17. Install dog nut and chain coil
