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: A Unit Weight: 2 |

Required skills |
Look for evidence that confirms skills in: identifying and clarifying sheathing application, material and other relevant specifications identifying surface materials preparing materials measuring sheathing material lengths to produce minimal wastage preparing site using personal protection mixing solutions in correct ratios preparing surface area, including the removal of contaminants selecting tools shielding surface areas not being sheathed applying materials minimising waste securing matting/cloth and waste overhang removing excess materials to produce minimum sanding/finishing requirements cleaning and storing tools sanding/re-coating sheathed surface area securing components/fittings cleaning and structurally testing fittings |
Required knowledge |
Look for evidence that confirms knowledge of: sheathing material specifications, properties and uses surface types, specifications, cleaning and preparation techniques site preparation and safe working practices sheathing preparation and safe working practices sealant types, specifications and uses masking procedures bonding/impregnating/reinforcing material specifications, properties and uses use of tools for sizing, measuring, mixing, applying sheathing and bonding/impregnating/reinforcing mixtures and finishing sealant application and finishing techniques sheathing application waste minimisation techniques securing materials and waste overhang removal of excess resin waste disposal obligations and regulations cleaning and storage of tools sanding/re-coating water testing techniques |
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. |
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. | |
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 |
