Title Use marine radar on a restricted limits vessel

    Level 3 Credits 10

    Purpose People credited with this unit standard are able to: relate the

    operating principles and conditions of marine radar to its use

    for position fixing and collision avoidance; operate marine

    radar; and use marine radar for navigation and collision

    avoidance.

    This unit standard is for people operating inshore vessels fitted

    with radar.

2 Definition

    Vessel operating practices refer to documented or undocumented systems on a

    vessel which may or may not form part of the Safe Ship Management System, and

    which comply with the Maritime Transport Act 1994, and Maritime Rules.

    3 This unit standard is designed for operators and/or observers of non-ARPA

    (restricted) radar and covers the requirements of the syllabus of Maritime New

    Zealand Restricted Radar Certificate.

Outcomes and evidence requirements

Outcome 1

    Relate the operating principles and conditions of marine radar to its use for position fixing and collision avoidance.

    Range operating principles nature of radio waves, pulse length, pulse repetition

    frequency, wavelength, power output, aerial design, main radar set components,

    tuning characteristics, 3cm and 10cm radars;

     operating conditions types of display, aerial siting, target characteristics,

    nature of radar reflections, weather conditions, minimum and maximum range,

    common faults.

Evidence requirements

    1.1 Operating principles and conditions are used to make predictions about the

    detection range and accuracy of marine radar, which are consistent with the

    referenced texts or equivalent texts.

    1.2 Operating principles and conditions are used to explain the effects of operating

    the controls which are accessible to the user, consistent with the referenced

    texts or equivalent texts.

    Range brilliance, gain, tuning, anti-sea clutter, differentiator (anti-rain

    clutter), range selector, fixed range rings, variable range

    marker/bearing cursor or equivalent, plot facility, alarm facility.

    1.3 Operating principles and conditions are used to interpret or identify displayed

    targets, consistent with the referenced texts or equivalent texts.

    1.4 Operating principles and conditions are used to explain the identification and

    minimisation of false echoes, consistent with the referenced texts or equivalent

    texts.

    Range includes but are not limited to: side lobes, second returns, multiple

    echoes, spoking.

    1.5 Inaccuracies, faults and limitations of radar use are explained consistent with

    the referenced texts or equivalent texts.

    Range includes but are not limited to horizontal beam width, vertical

    beam width, heading marker alignment, centring, aerial size,

    shadow sectors cause and effect of interference from other radar

    transmissions.

Outcome 2

Operate marine radar.

Evidence requirements

    2.1 Marine radar set is started up, controls are adjusted, and radar is operated in

    accordance with the manufacturer’s instruction manual.

    Range check scanner is clear and no one is aloft, controls all turned down,

    off, standby, on, brilliance, centring, range scale, gain, tuning, sea

    clutter, rain clutter.

    2.2 The internationally prescribed symbols for the user controls are identified in

    accordance with Symbols for controls on Marine Navigational Radar Equipment

    for marine radar performance.

    Range radar off, standby, run, gain, tuning, brilliance, range selector, anti-

    sea clutter, range rings, variable range marker, bearing marker,

    differentiator (anti-rain clutter), pulse length, type of display.

    2.3 Human factors affecting the use of radar are identified in accordance with

    vessel operating practices.

    Range fatigue, high workload in restricted visibility, bridge resource

    management and the need for teamwork.

Outcome 3

Use marine radar for navigation.

Evidence requirements

    3.1 Charted features are identified on the radar screen and used to fix the vessel’s

    position on the chart in accordance with the Radar and ARPA Manual.

    3.2 Radar targets are identified on the chart and used to fix the vessel’s position on

    the chart and to maintain navigational safety in accordance with the Radar and

    ARPA Manual.

    Range identified target range, identified target bearing, relative bearings,

    calculation of relative bearings to true bearings and vice-versa, 3-

    point radar-range fixes, parallel index lines.

Outcome 4

Use marine radar for collision avoidance.

Evidence requirements

    4.1 Other ship targets are monitored and plotted in real or simulated conditions to

    determine whether risk of collision or close quarters situation exists in

    accordance with the provisions of Maritime Rule Part 22.

    4.2 Action is taken in real or simulated conditions of restricted visibility to avoid

    other vessels in accordance with the provisions of Maritime Rule Part 22.

    4.3 Ship’s obligations when using radar for collision avoidance are interpreted in

    accordance with the provisions of Maritime Rule Part 22.

    Range lookout, safe speed, risk of collision, action to avoid collision,

    conduct of vessels in restricted visibility.

Please note

    Providers must be granted consent to assess against standards (accredited) by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

    Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.

    Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.

    Consent requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
