Elements and Performance Criteria

General context
Work must be carried out in compliance with mandatory rules and regulations and IMO Conventions and Codes including the relevant sections of the AMSA Marine Orders and ensure that applicable codes, guidelines and standards recommended by IMO, the classification societies and maritime industry organisations are taken into account.

Work is performed relatively independently under broad operational requirements, with accountability for self and others in achieving the prescribed outcomes within the limits of responsibility of an Engineer (Class 2

Work involves the application of management principles to the organisation of the maintenance and repair of the hull, structures, machinery and equipment typically found on a vessel of 750 kW propulsion power or more across a wide and often unpredictable variety of operational contexts. Contribution to the development and implementation of a broad plan or strategy for shipboard machinery maintenance and repair is required and accountability and responsibility for self and others in achieving the outcomes is involved.
