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!

DEFDV011B - Perform non-technical structural inspections underwater

What evidence can you provide to prove your understanding of each of the following citeria?

Prepare for underwater inspection

  1. Inspection task, target and available worksite data are determined and analysed.
  2. Inspection plan is developed consistent with the dive plan.
  3. Inspection equipment is selected, inspected and prepared.
  4. Inspection equipment is secured safely to/from the dive site.
  5. Access obstructions and other hazards are assessed and actionis taken to remove/reduce the risk.

Conduct underwater inspection

  1. Inspection equipment is secured on self for ease of accessibility and lack of interference to mobility and dive equipment.
  2. Target's surface is cleared of debris and/or marine growth.
  3. Visual analysis of target is conducted to identify significant features or defects.
  4. Lengths, gaps angles and holes are measured relative to a fixed datum and results are recorded.
  5. Visual imagery is taken of the target.

Instructions to Assessors

Evidence Guide

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to assist in providing information for an inspection report; to carry and secure the equipment throughout the dive; and to work safely throughout the operation.

Consistency in performance

Competency should be demonstrated conducting an inspection task requiring angular and linear measurements on one of the following:

pier/bridge – assessment is to be constructed around the examination of an existing pier/bridge requiring some expedient reinforcement to make fit for operational use

ship’s hull – assessment is to be constructed around a sonar dome housing inspection and poker/feeler gauge surveys.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the ocean supported by questioning on shore or aboard vessels.

When practicable, assessment should relate to the diver’s vocational focus.

Assessment should be conducted over a time frame that allows for the safe demonstration of competency.

Specific resources for assessment

Access to a complete range of diving, safety and accessory equipment; and inspection equipment.

Required Skills and Knowledge
