Description
Employability Skills
Learning Outcomes and Application This unit involves the skills and knowledge required to maintain safe navigation of a vessel through the use of radar, automatic radar plotting aids (ARPAs) and other bridge equipment to determine vessel position.This unit applies to people working in the maritime industry in the capacity of:Master of a commercial vessel less than 80 metres in length within the exclusive economic zone (EEZ)Master of a commercial vessel less than 500 gross tonnage (GT)Master of a commercial vessel UnlimitedWatchkeeper Deck.Licensing/Regulatory InformationLegislative and regulatory requirements are applicable to this unit.Regulatory requirements include STCW International Maritime Organization (IMO) model course competencies and areas of knowledge, understanding and proficiency, together with the estimated total hours required for lectures and practical exercises. Teaching staff should note that timings are suggestions only and should be adapted to suit individual groups of trainees depending on their experience, ability, equipment and staff available for trainingNear Coastal Qualifications:This unit is one of the requirements to obtain Australian Maritime Safety Authority (AMSA) certification as a Master less than 80 metres Near Coastal as defined in the Marine Order 505 (Certificates of competency - National Law) 2013.Blue Waters Qualifications:This unit is one of the requirements to obtain AMSA certification as a Master of a commercial vessel less than 500 gross tonnage (GT), Master Unlimited or Watchkeeper Deck and to meet regulatory requirements this unit must be delivered consistent with Marine Orders and with the relevant sections of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW).
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

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.

Practical assessment must occur in a workplace, or realistic simulated workplace, under the normal range of workplace conditions.

Simulations and scenarios may be used where situations cannot be provided in the workplace or may occur only rarely, in particular for situations relating to emergency procedures and adverse weather conditions where assessment would be unsafe, impractical or may lead to environmental damage.

Resources for assessment must include access to:

applicable documentation, such as legislation, regulations, codes of practice, workplace procedures and operational manuals

tools, equipment, machinery, materials and relevant personal protective equipment (PPE) currently used in industry.

Elements of Competency Performance Criteria              
Element: Use radar and ARPA to safely navigate
  • Radar is operated according to manufacturer instructions to produce data on position of vessel, other vessels and fixed objects
       
Element: Radar plot is constructed on radar plotting sheet and automatic plotting devices are initialised
       
Element: Systematic radar and/or ARPA observations of vessels in the vicinity are made and risk of collision is determined
       
Element: Radar data is used to obtain a position fix for vessel using electronic bearing lines and variable range markers
       
Element: Radar bearings are corrected for vessel heading and compass error, as appropriate
       
Element: Adjustments are made to vessel course and speed to maintain safety of navigation
       
Element: Manoeuvring signals are made at appropriate time according to regulations
       
Element: ARPA information is analysed and interpreted taking into account limitation of equipment and prevailing circumstances and conditions
       
Element: Set up bridge equipment
  • Bridge equipment is initialised and displays are set up and maintained
       
Element: Operational performance and accuracy of bridge equipment is confirmed, and appropriate action is taken when performance is out of limits
       
Element: Bridge navigation watch alarm system (BNWAS) and voyage data recorder are activated according to manufacturer requirements and organisational procedures
       
Element: Any false echoes and misrepresentations are detected, identified and rejected
       
Element: Use bridge equipment to safely navigate
  • Bridge equipment is safely and efficiently used to conduct navigation of vessel
       
Element: Position of vessel is monitored during voyage to ensure planned passage is followed
       
Element: Movements of vessels in the vicinity are monitored to ensure collision situations do not occur
       
Element: Bridge equipment is used and maintained according to manufacturer requirements and organisational procedures
       
Element: Maintain navigational records
  • Navigational data produced by bridge equipment that should be retained to conform with organisational procedures and regulatory requirements is identified
       
Element: Navigational data is stored electronically or in hard copy as required by organisational procedures and regulatory requirements
       
Element: Security and access requirements for data are adhered to according to organisational procedures
