Unit Descriptor

Unit descriptor 

This unit covers installing and testing marine auxiliary systems. Where installation only is required, Unit MEM25015A (Assemble and install equipment and accessories/ancillaries) should be selected.

Application of the Unit

Application of the unit 

This unit applies to practices for the installation and testing of auxiliary systems for marine vessels, such as bilge, freshwater, fire (water) and sanitary plumbing systems. Work may be undertaken autonomously or as part of a team.

Lifting systems include davits, crane and winch units.

Locations may include external and internal locations for foundations, footings, beds and frameworks etc. completed prior to installation and commissioning.

All specifications are applied via engineering drawings, written or verbal instructions.

Routine modifications and alterations are of a minor nature not requiring specification changes or technical recording.

Testing should be undertaken in accordance with manufacturer specifications, guidelines, requirements and limitations.

Testing procedures may include engineering practices for determining correct operational function of mechanical, fluid power systems, equipment, components and associated items.

Tasks may be undertaken in a workshop/site, moored or in a sea trial situation. All work and work practices should be undertaken to regulatory and legislative requirements.

Where installation only is required, Unit MEM25015A (Assemble and install equipment and accessories/ancillaries) should be selected.

Evidence Guide


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 install and test operations of marine auxiliary systems. 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 installing and testing operations of marine auxiliary systems, 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. 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 

Range Statement


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.

Test equipment 

Mechanical, pneumatic/electro-pneumatic, electronic (analog/digital) and associated instruments that measure variables such as temperature, pressure, flow rate, levels, light, density or any other process variable
