PUADEFDV009B
Conduct an underwater search of a ship's hull

This unit covers the competency required to conduct an exterior search of the underwater component of a ship's hull.Note: This Unit of Competency relates, in part, to 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.

Application

The application of this unit in the workplace - the environments, complexities and situations involved - will be written during Phase II of the Review of the PUA00 Public Safety Training Package.

This text will be useful for the purposes of job descriptions, recruitment advice or job analysis; where possible, it will not be too job specific to allow other industries to import it into other Training Packages, where feasible.

Evidence Required

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

Assessment must confirm the ability to work safely throughout the operation.

Consistency in performance

Competency should be demonstrated during a search to locate an object (such as a mine) that is attached to a ship’s hull (and is of a minimum underwater length of 30 m).

The search is to be conducted under poor visibility (max 0.5 m) demanding the use of manual search techniques.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the ocean over a range of oceanic, diurnal and nocturnal environments supported by questioning on shore or aboard vessels.

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

Specific resources for assessment

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

Guidance information for assessment

Information that will assist or guide assessment will be written during Phase II of the Review of the PUA00 Public Safety Training Package.
