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 repair marine vessel surfaces and structures. 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 repairing marine vessel surfaces and structures, 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

Required skills

Look for evidence that confirms skills in:

implementing written and verbal instruction

recognising structure and components

identifying type and extent of structural damage area/sector

selecting suitable repair method and materials

selecting and using tools/equipment

preparing site to job, safety and environmental requirements

preparing materials to affect repairs

using personal protection

sourcing and applying correct fastening methods

disassembling components, where required

repairing damage to timber, fibre reinforced plastics and metal surfaces and structures

reassembling and or replacing components

reconnecting/refitting through-hull fittings

preparing surface in readiness for application of surface finishes and protective coatings, where required

applying surface finishes and protective coatings, matching colours and textures, where required

testing and re-establishing watertight integrity, where required

disposing of waste, and general housekeeping

Required knowledge

Look for evidence that confirms knowledge of:

structure, component, surface, core identification

effect of damage in relation to the integrity of the hull and structures and the capacity of the vessel to withstand stresses encountered at sea

repair methods and materials for timber, fibre reinforced plastics and metal surfaces and structures

characteristics of chosen materials

affect on structural and or watertight integrity

tools/equipment, their specification and application

techniques for reinforcement/shoring/support

methods for re-constructing damaged components

fastening methods and application procedure

procedures used in preparing, re-finishing or re-coating

types and applications of coatings

colour and texture matching techniques

safe work procedures

methods of testing and re-establishing watertight integrity

procedures for pre-delivery clean up of damaged sector

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.

Repairs

Foreign contact damage such as reef, jetty collision; environmental problems such as fungi, marine and insect effects on timber; variants of severe corrosion in metals, such as electrolysis and galvanic corrosion and with fibre reinforced plastics construction, such as osmosis

Structural repair includes impediments to structural and watertight integrity, for example, holed hull, star-cracking in fibre reinforced plastics, replacement of hull and deck

Planking, replacement of cracked hatch tops and portlight 'windows', hull penetration causing ingress of water
