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 independently under broad operational requirements, with accountability for self and others in achieving the prescribed outcomes within the scope of responsibility of an Engineer (Class 1).

Work involves the application of marine engineering management practice to the planning and scheduling of the operation of the vessel's power installation and auxiliary machinery on a vessel of 3,000 kW over the range of operational situations during a voyage. Contribution to the development and implementation of a broad plan or strategy for the operation of the vessel's power installation and auxiliary machinery is required and accountability and responsibility for self and others in achieving the outcomes is involved.
