Description
|
This unit involves the skills and knowledge required of a Master 5 or Skipper 3 to maintain safe navigation of a commercial vessel through the use of radar and other electronic navigational aids.
This includes initialisation and operation of radar and other modern navigational systems, interpreting all available navigational data and using it for avoiding collisions and ensuring the safe navigation of the vessel.

Performance Criteria
|
1 Set up radar and other electronic navigational instruments
1.1 Radar is initialised and used in accordance with established procedures and manufacturer’s instructions to assist in the safe navigation of the vessel
1.2 Operational performance and accuracy of the radar is confirmed and appropriate action taken where performance is out of limits
1.3 False echoes are detected and discounted
2 Use radar and other electronic navigational instruments
2.1 Radar and GPS/DGPS is operated in accordance with manufacturer’s instructions to produce data on the position of other vessels and fixed objects
2.2 Data produced by the radar and GPS/DGPS is interpreted and used to assist navigational command decisions, taking into account known limitations and errors associated with the equipment
2.3 A radar plot is constructed on a radar plotting sheet using systematic radar observations
2.4 Data on the radar plotting sheet is interpreted and analysed to anticipate potential collisions
2.5 Information obtained through the analysis of the radar plots is used to make informed command decisions on action needed to avoid collision
2.6 Radar plot is correctly constructed and used to determine avoiding action when necessary
2.7 Radar data is used to obtain a position fix for the vessel using electronic bearing lines and variable range markers
2.8 Radar bearings are corrected for vessel’s heading and compass error as appropriate
3 Maintain navigational records
3.1 Plotting sheets used to analyse navigational situations and to inform command decisions are stored in accordance with company procedures and regulatory requirements
3.2 Records of navigational data produced by radar and GPS/DGPS are stored electronically or in hard copy as required by company procedures and regulatory requirements

- while underway
- during berthing and unberthing operations
- while anchoring or mooring
- Equipment may include:
- radar
- GPS and DGPS satellite systems as applied to navigation problems
- integrated navigation systems
- The use of radar and GPS/DGPS to assist safe navigation may include:
- avoidance of collision with another vessel
- fixing the position of the vessel
- tracking of other vessels
- assistance in making of command navigational decisions
- navigating during search and rescue operations
- Documentation and records may include:
- relevant maritime regulations
- operational orders
- navigational charts
- radar plotting charts
- regulations for preventing collisions at sea
- safety management system plans, procedures, checklists and instructions (where relevant)
- vessel’s log
- company procedures for the use of navigational aids
- systems manufacturer’s instructions and recommended procedures
- notices and instructions of relevant maritime authorities
- relevant Australian standards
- Applicable legislation, regulations and codes may include:
- regulations for preventing collisions at sea
- relevant Commonwealth, State and Territory marine and OH&S legislation
- Commonwealth, State and Territory
