Elements and Performance Criteria

General context
Work must be carried out in compliance with the relevant maritime regulations, tanker safety guides and port regulations related to oil tanker safety, operations and pollution control.

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 special safety precautions, operational procedures and hazard minimisation strategies to the management of the operations, maintenance and emergency situations on an oil tanker. Contribution to the development of integrated safety management plan for an oil tanker 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 development and implementation of an ISM management plan for operations, maintenance activities and emergencies on an oil tanker.
