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

• Chief Mate
• Deck Officers
• Engineering Officers
• Engineers
• Masters
• Ratings.

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 Chief Mate, Deck Officers, Engineering Officers, Engineers, Masters and Ratings for basic operations on liquefied gas tankers and to meet regulatory requirements this unit must be delivered consistent with Marine Orders and with the relevant sections of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW).
• Those regulatory requirements include STCW International Maritime Organization (IMO) model course competencies and areas of knowledge, understanding and proficiency, together with the estimated total hours required for lectures and practical exercises. Teaching staff should note that timings are suggestions only and should be adapted to suit individual groups of trainees depending on their experience, ability, equipment and staff available for training.

Recognise hazardous situation 

4.1 

Source of hazard is identified according to organisational procedures

4.2 

Risk is assessed considering severity and likelihood of consequences

4.3 

Control measures to minimise risk are implemented to level of responsibility or referred to appropriate person for further action

4.4 

Containment procedures are applied where appropriate

4.5 

Appropriate safety procedures are followed and personal protective equipment (PPE) is used according to organisational procedures

4.6 

Risk is eliminated, where possible, and if not practical, actions are taken to control risk

5 

Take precautions to prevent pollution of the environment from release of liquefied gases 

5.1 

Procedures to prevent pollution are identified and observed at all times

5.2 

Measures to prevent pollution during normal and emergency situations are applied according to regulatory requirements and organisational procedures

5.3 

All relevant information is immediately reported to appropriate persons when a vapour leak or cloud is detected or a malfunction has occurred that poses a risk of a vapour leak or cloud

5.4 

Shore-based response personnel are promptly notified when a vapour leak or cloud occurs

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

This unit replaces and is equivalent to MARA001 Contribute to safe cargo operations on liquefied gas tankers.

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Practical assessment must occur in a workplace, or realistic simulated workplace, under the normal range of workplace conditions.

Simulations and scenarios may be used where situations cannot be provided in the workplace or may occur only rarely, in particular for situations relating to emergency procedures and adverse weather conditions where assessment would be unsafe, impractical or may lead to environmental damage.

Resources for assessment must include access to:

• applicable documentation such as legislation, regulations, codes of practice, workplace procedures and operational manuals
• tools, equipment, machinery, materials and relevant personal protective equipment (PPE) currently used in industry, including gas monitoring instruments and oxygen indicators.
