ELEMENT

PERFORMANCE CRITERIA

1. Prepare for underwater inspection

1.1 Inspection task, target and available worksite data are determined and analysed.

1.2 Inspection plan is developed consistent with the dive plan.

1.3 Inspection equipment is selected, inspected and prepared.

1.4 Inspection equipment is secured safely to/from the dive site.

1.5 Access obstructions and other hazards are assessed and actionis taken to remove/reduce the risk.

2. Conduct underwater inspection

2.1 Inspection equipment is secured on self for ease of accessibility and lack of interference to mobility and dive equipment.

2.2 Target's surface is cleared of debris and/or marine growth.

2.3 Visual analysis of target is conducted to identify significant features or defects.

2.4 Lengths, gaps angles and holes are measured relative to a fixed datum and results are recorded.

2.5 Visual imagery is taken of the target.

3. Conduct post-inspection procedures

3.1 Inspection equipment is de-serviced and stored after use.

3.2 Non-technical inspection report is drafted and submitted according to organisational procedures.

This describes the essential skills and knowledge and their level, required for this unit.

Required Skills

ability to dive

make oral presentations

make underwater field notes and sketches

measure instruments

take photographs

write reports

Required Knowledge

basic architecture of piers and bridges

basic mechanics

dive physics

dive equipment

general occupational/diving safety awareness

oceanography

relevant references and Australian Standards

work hazards

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.

The Range Statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording in the Performance Criteria is detailed below.
