Description
Notes
Elements and Performance Criteria
1. Use radar and ARPA to safely navigate
  • 1.1 Radar is operated according to manufacturer instructions to produce data on position of vessel, other vessels and fixed objects
  • 1.2 Radar plot is constructed on radar plotting sheet and automatic plotting devices are initialised
  • 1.3 Systematic radar and/or ARPA observations of vessels in the vicinity are made and risk of collision is determined
  • 1.4 Radar data is used to obtain a position fix for vessel using electronic bearing lines and variable range markers
  • 1.5 Radar bearings are corrected for vessel heading and compass error, as appropriate
  • 1.6 Adjustments are made to vessel course and speed to maintain safety of navigation
  • 1.7 Manoeuvring signals are made at appropriate time according to regulations
  • 1.8 ARPA information is analysed and interpreted taking into account limitation of equipment and prevailing circumstances and conditions
2 Set up bridge equipment
  • 2.1 Bridge equipment is initialised and displays are set up and maintained
  • 2.2 Operational performance and accuracy of bridge equipment is confirmed, and appropriate action is taken when performance is out of limits
  • 2.3 Bridge navigation watch alarm system (BNWAS) and voyage data recorder are activated according to manufacturer requirements and organisational procedures
  • 2.4 Any false echoes and misrepresentations are detected, identified and rejected
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 used and 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
