Description
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.
Notes
Elements and Performance Criteria
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 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

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, the required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the Elements, Performance Criteria, Required Skills, Required Knowledge and include:
operating marine radar systems and equipment on an automatic radar plotting aids (ARPA) system
attention to appropriate level of detail in recordkeeping.
Context of and specific resources for assessment
Performance is demonstrated consistently over time and in a suitable range of contexts.
Resources for assessment include access to:
industry-approved marine operations site where using wheelhouse equipment may be conducted
approved radar simulator where ARPA training can be conducted
tools, equipment and personal protective equipment currently used in industry
relevant regulatory and equipment documentation that impacts on work activities
range of relevant exercises, case studies and/or other simulated practical and knowledge assessments
appropriate range of relevant operational situations in the workplace.
In both real and simulated environments, access is required to:
relevant and appropriate materials and equipment
applicable documentation including workplace procedures, regulations, codes of practice and operation manuals.
Method of assessment
Practical assessment must occur in an:
appropriately simulated workplace environment and/or
appropriate range of situations in the workplace.
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate to this unit:
direct observation of the candidate using wheelhouse equipment
direct observation of the candidate applying relevant WHS/OHS requirements and work practices.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
In all cases where practical assessment is used it should be combined with targeted questioning to assess Required Knowledge.
Assessment processes and techniques must be appropriate to the language and literacy requirements of the work being performed and the capacity of the candidate.
