Learning Outcomes and Application This unit involves the skills and knowledge required to establish, organise and implement a preventative and reactive maintenance program and capabilities on 240 to 440 volt (V) alternating current (AC) electrical systems on a vessel.It includes verifying maintenance requirements, establishing maintenance systems, organising maintenance activities, supervising maintenance tasks, performing planned maintenance activities, performing breakdown maintenance and monitoring, and adjusting and reporting on implementation of maintenance plan.This unit of competency applies to people working in the maritime industry in the capacity of:Chief Engineer on vessels with inboard engines less than 1500 kW within the exclusive economic zone (EEZ)Second Engineer on vessels with inboard engines less than 3000 kW within the EEZChief or Second Engineer on vessels with outboard engines with unlimited propulsion power within the EEZan assistant under the direct supervision of the Chief Engineera worker in the engine room of a vessel less than 80 metres long with propulsion power less than 3000 kW. Licensing/Regulatory InformationLegislative and regulatory requirements are applicable to this unit. This unit is one of the requirements to obtain Australian Maritime Safety Authority (AMSA) certification as a Marine Engine Driver Grade 1 Near Coastal as defined in the National Standard for Commercial Vessels (NSCV) Part D. Note: Relevant state/territory qualification requirements apply to persons carrying out installation, maintenance and/or repair of electrical circuits or systems that are 50 V AC or above, or 120 V direct current (DC) or above.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Practical assessment must occur in a workplace, or realistic simulated workplace, under the normal range of workplace conditions.

Simulations and scenarios may be used where situations cannot be provided in the workplace or may occur only rarely, in particular for situations relating to emergency procedures and adverse weather conditions where assessment would be unsafe, impractical or may lead to environmental damage.

Resources for assessment must include access to:

a commercial vessel with inboard diesel propulsion power of greater than or equal to 375 kW or appropriate engine and auxiliary system ashore

applicable documentation, such as legislation, regulations, codes of practice, workplace procedures and operational manuals

tools, equipment, machinery, materials and personal protective equipment (PPE) currently used in industry

electrical systems, including:

AC alternator (above 240 V AC and up to 440 V AC)

batteries

electrical motor starting circuits

emergency electrical supply

power and lighting

shore supply

switchboards.
