Elements and Performance Criteria

General context
Work must be carried out in compliance with the relevant sections of the AMSA Marine Orders and IMO STCW 95 Code and Convention, ISM Code, roll-on roll-off vessel safety guides and port regulations related to roll-on roll-off vessel operations.

Work is performed relatively independently under broad operational requirements, with accountability and responsibility for self and others in achieving the prescribed outcomes.

Work involves the application of a significant range of operational and supervisory principles and procedures, safety precautions and hazard minimisation strategies to the management of the loading/unloading, vessel stability and the embarkation/disembarkation of passengers on a roll-on roll-off vessel. Contribution to the development of a broad plan for cargo handling, vessel stability and the embarkation/disembarkation of passengers is required and accountability and responsibility for self and others in achieving the outcomes is involved.

Work requires significant judgement in planning, technical and leadership functions related to the loading/unloading, and embarkation/disembarkation of passengers on a roll-on roll-off vessel.

Loading/unloading, and embarkation/disembarkation of passengers on a roll-on roll-off vessel may be carried out:
by day or night in both normal situations
under any possible operational conditions.

Types of cargo may include:
road vehicles including cars trucks, buses, etc.
rail cars
other forms of transport units
