Application
This unit involves the skills and knowledge required to maintain safe navigation of a commercial vessel through the use of radar and other equipment used for the navigation of a vessel.
This unit applies to people working in the maritime industry on a range of vessels up to 80 metres.
This unit has links to legislative and certification requirements.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. | ||
1 | Set up wheelhouse navigation equipment | 1.1 | Wheelhouse navigation equipment is initialised and displays are set up and maintained |
1.2 | Operational performance and accuracy of wheelhouse equipment is confirmed and appropriate action is taken when performance is out of limits | ||
1.3 | Misrepresentation of information is detected and corrected or allowed for | ||
2 | Use radar to navigate safely | 2.1 | Radar is operated according to manufacturer instructions to produce data on position and speed of vessel, other vessels and fixed objects |
2.2 | Radar plot is constructed on a radar plotting sheet or automatic plotting devices are initialised | ||
2.3 | Systematic radar observations of vessels in the vicinity are made where there is a risk of collision | ||
2.4 | Radar data is used to obtain a position fix for vessel using electronic bearing lines and variable range markers | ||
2.5 | Radar bearings are corrected for vessel heading and compass error as appropriate | ||
2.6 | Radar plotting data is analysed to anticipate potential collisions | ||
2.7 | Analysis is used to make informed command decisions on action needed to avoid collisions | ||
3 | Use wheelhouse navigation equipment | 3.1 | Wheelhouse navigation equipment is safely and efficiently used to conduct navigation of the vessel |
3.2 | Position of vessel is monitored during voyage to ensure planned passage is followed | ||
3.3 | Movement of vessels in the vicinity is monitored to ensure collision situations do not occur | ||
3.4 | Wheelhouse navigation equipment is maintained according to manufacturer requirements and organisational procedures | ||
4 | Maintain navigational records | 4.1 | Navigational data produced by wheelhouse navigation equipment that should be retained to conform with organisational procedures and regulatory requirements is identified |
4.2 | Navigational data is stored electronically or in hard copy as required by organisational procedures and regulatory requirements | ||
4.3 | Security and access requirements for data are adhered to according to organisational procedures | ||
Evidence of Performance
Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least one occasion and include:
interpreting radar displays and indications
operating marine radar systems and equipment on a vessel
operating marine radar systems and equipment on an automatic radar plotting aid (ARPA) system
operating other electronic navigational instruments and equipment on a vessel
reading and interpreting service manuals and instructions for radar and other electronic navigational aids
recognising faulty radar equipment and taking appropriate action
recognising problems when using radar and other electronic navigational aids to maintain safe navigation and taking appropriate action
recognising radar display of search and rescue transponders (SART) and racon signals.
Evidence of Knowledge
Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:
different types of navigational aids, including their features, key applications and operational characteristics
limitations and potential errors associated with each type of electronic navigational aid
methods for the interpretation and analysis of navigational data produced by radar and other electronic navigational instruments
procedures for the initialisation and operation of radar and other electronic navigational instruments
procedures to determine compass accuracy by azimuth, amplitude or other method appropriate to the standards of watchkeeping practice when beyond sight of land
procedures for the use of data generated by radar and other electronic navigational instruments
relevant sections of state and territory regulations, National Standard for Commercial Vessels (NSCV) and Uniform Shipping Laws (USL) Code dealing with navigational equipment and the responsibilities of a Master or Deck Officer
techniques for the use of radar and other electronic navigational instruments
terminology and principles of operation of radar and other electronic navigation aids typically used on vessels
work health and safety (WHS)/occupational health and safety (OHS) requirements and work practices.
Assessment Conditions
Assessors must satisfy National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) assessor requirements.
Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that reflect workplace conditions.
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.
Resources for assessment must include access to:
tools, equipment, machinery, materials and personal protective equipment currently used in industry
applicable documentation such as legislation, regulations, codes of practice, workplace procedures and operational manuals
range of relevant exercises, case studies and/or simulations.
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance. |
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency. |
