Description
This unit covers the competency required to conduct non-technical structural inspections such as examining bridges, piers or ships' hulls.The unit includes general qualitative inspection (visual and manual) as well as quantitative analysis such as the taking of basic measurements including angles, dimensions and lengths.Note: Elements of this assessment are aligned with the existing standards of the Australian Diver Accreditation Scheme (ADAS). All information was correct at the time of development of this Unit of Competency; however, any diver seeking ADAS accreditation should consult ADAS and not rely on the information contained in this unit.
Notes
Elements and 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.
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.

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.
