Unit of Competency MEM25006B - Undertake marine sheathing operations
Description This unit covers applying sheathing to marine structures (sheathing operations). Basic composite sheathing operations are covered by Unit MEM25001B (Apply fibre-reinforced materials).
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit covers the application of sheathing to marine structures. Work is undertaken autonomously, in a team environment or a combination of both. Predetermined standards of quality and safety are observed and work is carried out to standard operational procedures. Tasks may be carried out on prepared new and old surface areas. Sealing may involve various materials to ensure a watertight seal on a variety of components.Where application of marine coatings is undertaken, Unit MEM08002C (Pre-treat work for subsequent surface coating) and/or Unit MEM08004B (Finish work using wet, dry and vapour deposition methods) should also be selected. Basic sheathing operations are covered by Unit MEM25001B (Apply fibre-reinforced materials).Where materials and chemicals subject to codes and regulations are stored, Unit MEM13003B (Work safely with industrial chemicals and materials) should also be considered.Band: AUnit Weight: 2

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 undertake marine sheathing operations. 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 marine sheathing operations 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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

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.

Surface materials

Copper, gal sheet and other metals, fabric, sheathing resins, a range of adhesives, sealants and fillers and where applicable may be applied to timber, fibre-reinforced plastics and metal surface areas

Hand tools for mixing and application

Mixing sticks, putty/broad knives, scales, tins of equal size, trowels, squeegee, brushes and rollers

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
