Description
This unit involves the skills and knowledge required to maintain safe navigation of a vessel through the use of radar and other bridge equipment to determine vessel position.
Notes
Elements and Performance Criteria
1 Set up bridge equipment
  • 1.1 Bridge equipment is initialised and displays are set up and maintained
  • 1.2 Operational performance and accuracy of bridge equipment is confirmed and appropriate action is taken when performance is out of limits
  • 1.3 Any false echoes and misrepresentations are detected, identified and rejected
2 Use radar to safely navigate
  • 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 radar plotting sheet and automatic plotting devices are initialised
  • 2.3 Systematic radar observations of vessels in the vicinity are made and risk of collision is determined
  • 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 Adjustments are made to vessel course and speed to maintain safety of navigation
  • 2.7 Manoeuvring signals are made at appropriate time according to regulations
3 Use bridge equipment to safely navigate
  • 3.1 Bridge equipment is safely and efficiently used to conduct navigation of vessel
  • 3.2 Position of vessel is monitored during voyage to ensure planned passage is followed
  • 3.3 Movements of vessels in the vicinity are monitored to ensure collision situations do not occur
  • 3.4 Adjustments are made to vessel course and speed to maintain safety of navigation
  • 3.5 Manoeuvring signals are made at appropriate time according to regulations
  • 3.6 Bridge equipment is maintained according to manufacturer requirements and organisational procedures
4 Maintain navigational records
  • 4.1 Navigational data produced by bridge 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:
attention to appropriate level of detail in recordkeeping
ensuring currency of relevant legislative and regulatory knowledge.
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 bridge equipment may 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 bridge 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.
