Unit Of competency

Modification History

Release 1. New unit of competency. Licensing/regulatory information has been incorporated in accordance with Regulatory requirements. Assessment Requirements have been strengthened in accordance with Regulatory requirements.

Application

This unit involves the skills and knowledge required to complete basic maintenance of marine internal combustion engines, propulsion plant and auxiliary systems.

This unit of competency applies to people working in the maritime industry in the capacity of:

  • chief engineer on vessels with an inboard engine with propulsion power <750 kW within the exclusive economic zone (EEZ) or
  • second engineer on vessels with an inboard engine with propulsion power <1500 kW, within the EEZ or
  • chief or second engineer with an outboard engine with unlimited propulsion power within the EEZ or
  • assistant under direct supervision of a chief engineer; and
  • worker in an engine room of a vessel < 80 m long with propulsion power <3000 kW.

Licensing/Regulatory Information 

Legislative 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 2 NC, as defined in the National Standard for Commercial Vessels (NSCV) Part D. The AMSA mandated practical assessment (AMPA) is a requirement for AMSA certification. The Australian Maritime Safety Authority (AMSA) mandated practical assessment (AMPA) will cover a range, but not all, of the requirements identified in the Performance Evidence and Knowledge Evidence. The AMPA shall be undertaken in accordance with its instructions.

Assessors of AMPA must hold as a minimum:

  • a current certificate of competency issued under Marine Safety (Domestic Commercial Vessel) National Law Act 2012 at the same level as the qualification being assessed with at least 12 months’ relevant sea service, or
  • a relevant seafarer certificate, as engineer issued under the Navigation Act 2012.
