Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.

Skills 

Description 

Learning skills to:
  • locate appropriate sources of information efficiently.

Reading skills to:
  • interpret information from manufacturer and workshop literature when seeking marine cooling system specifications and procedures.

Writing skills to:
  • legibly and accurately fill out workplace documentation when reporting diagnostic findings, making repair recommendations, and recording parts and material used.

Oral communication skills to:
  • clarify instructions
  • report diagnostic findings and make repair recommendations.

Numeracy skills to:
  • measure exhaust and cooling system components and use basic mathematical operations, including addition, subtraction, multiplication and division to calculate distances, areas, volumes, tolerances and deviations from manufacturer specifications.

Planning and organising skills to:
  • plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes.

Technology skills to:
  • use precision measuring equipment, such as infra-red thermometers.

Range of Conditions

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Safety requirements  must include:
  • work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for:
  • lifting and supporting exhaust and cooling system components
  • working with hot exhaust and cooling system components.

Environmental requirements  must include:
  • procedures for trapping, storing and disposing of materials released from exhaust systems.

Unit Mapping Information

Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the marine exhaust and cooling systems that they have worked on, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

  • marine repair workplace or simulated workplace
  • workplace instructions
  • manufacturer exhaust and cooling system specifications
  • two different marine vessels with faults in their fresh water cooling exhaust and cooling systems
  • two different marine vessels with faults in their raw water exhaust and cooling systems
  • diagnostic equipment for marine exhaust and cooling systems
  • tools, equipment and materials appropriate for dismantling, testing, repairing and reassembling marine exhaust and cooling systems.
