This unit applies to cosmetic maintenance and repair practices used in the marine industry.

Cosmetic maintenance and repair practices apply across a range of timber, fibre reinforced plastics and metal materials.

Work involves routine maintenance-related inspection of hull and superstructure sectors, surfaces and fittings.

A range of hand held tools, equipment and materials is used to suit specific maintenance/repair requirements.

Where repair of marine surfaces and structures is carried out, Unit MEM25008C (Repair marine vessel surfaces and structures) should be selected.

Where slipping is required, or when working on a slipped craft, Unit MEM25014B (Perform marine slipping operations) should also be selected.

Relevant units related to specific applications and materials should also be selected as required.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to maintain marine vessel surfaces. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with maintaining marine vessel surfaces, or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

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, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Cosmetic maintenance/repair

Cosmetic environmental and other damage including chips in fibre reinforced plastics, minor corrosion in metal, caulking in timber surfaces, wear and corrosion of fittings

Cleaning tools, equipment and materials

Hand scrapers and scouring pads, handheld power tools, abrasive materials and equipment and associated dust extraction accessories, high-pressure blast cleaning equipment and chemical cleaners such as acid wash, solvent, detergent
