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

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

Interpret work order and locate and apply information.

Apply safety requirements, including the isolation of equipment and use of personal protective equipment.

Follow work instructions, operating procedures and inspection processes to:

minimise the risk of injury to self and others

prevent damage and wastage of goods, equipment and products

maintain required production output and product quality.

Complete failure analyses on a minimum of three different light marine transmission systems with real or simulated multi-system and intermittent faults and identify, evaluate, select and document the most appropriate rectification measure.

Analyse and validate or recommend variations to a minimum of two available repair/modification procedures for different light marine transmission systems.

Document and report the diagnostic process and findings and recommended rectification for the above.

Work effectively with others.

Modify activities to cater for variations in workplace context and environment.

Context of, and specific resources for assessment

Assessment may occur on the job or in a workplace simulated facility with process equipment, materials, work instructions and deadlines.

Access to a requirement and objective(s) for analysis and evaluation, light marine transmission systems with real or simulated faults, monitoring processes and testing equipment appropriate to the objective(s), research facilities and technical information and a work environment.

Method of assessment

Assessment of this unit of competence is most likely to be project related under real or simulated conditions and require portfolios or other forms of indirect evidence of process. Direct evidence may include certification of compliance of the final outcome/product or authorisation for use by a competent authority.

Assessment must confirm the inference that competence is able not only to be satisfied under the particular circumstances, but is able to be transferred to other circumstances.

Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.

detailed knowledge of engine and shaft alignment for inboard and stern drive installations.

detailed knowledge of propeller theory.

general knowledge of marine digital computing system.

general knowledge of the theory of diagnosis, including concept, design and planning.

detailed knowledge of the types, functions, operations and limitations of diagnostic testing equipment.

general knowledge of the methods and processes for documenting and reporting diagnostic findings and recommendations.

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.

Failure analysis and evaluation process

The objective of the failure analysis and evaluation process may be to determine fault rectification measures, to effect variation in system characteristics and parameters or to enhance system performance.

Failure analysis

Failure analysis is to include component failure, cooling, hydraulic pressures, driveline vibration, driveline sealing, shift control, and propeller selection and failure.
