        4.   Protection of vessels and port facilities

  Q. AIS operation
      -     should be operational when vessel are underway, making way, moored or at
            anchor.
      -     the AIS may be switched off if the operational of AIS might compromise the
            safety or security of the vessel for example when navigating in sea areas
            where pirates or armed robbers are known to operate and the event must
            be recorded in the official logbook.

             anchored, moored), safety related short message (manually input/entered
             during voyage)

Q. AIS limitation       
     The information given by AIS may not be a complete picture of situation 
     around the ship due to some limitation;
       1.  other vessel might not be fitted with AIS example fishing boat, warships
       2.  other vessel AIS might be switched off due to security reason.
       3.  The accuracy of information received depends on the accuracy of
             the information input by the target vessel.

Q Ship Routing - explain
     The purpose of ship routing is to improve the safety of navigation in concerning
     areas and in areas where the density of traffic is great or where the freedom of   
     movement of shipping inhibited by restricted sea room, the existence of obstruction  
     to navigation, limited depth or unfavorable meteorological conditions.

     Following are the matters related to ship routing:
  1. Routing system
  2. TSS
  3. Traffic separation zone or line
  4. Traffic line
  5. Round about
  6. Inshore traffic zone

  10. Precautionary area
  11. Area to be avoided
  12. Established direction of traffic flow
  13. Recommended direction of traffic flow
Q. What information you get in sailing directions / pilot book?
           1. Details regarding the coast – approach (particulars area)
           2. Dangers / no go areas
           3. Local wx
           4. Local / harbour rules, port authority
           5. Working channel etc
           6. Region A/B, buoyage system
           7. Panoramic / photographic view.
           8. Area tidal information, depth / draught
           9. Dock details.

Q. Compass Error
     Demonstrate;
1.       Determine Compass Error - simple exercise by given position, time and Compass Bearing.
2.       Other method to determine the Compass Error example by Transit etc
3.       Use of azimuth mirror

Q. Limitation of electronic chart systems (ECDIS and other electronic chart systems)

     There are some limitations of the ECDIS as followings:

  1. Chart Accuracy
ECDIS provides the navigator with a tactical tool which incorporates a high accuracy positioning device.  The navigator can "zoom" in on an ECDIS chart to a scale beyond the intended accuracy of the charted information.

2.     Technical limitation of other devices
The accuracy is also depends on the technical limitation of other devices linked to the ECDIS, such as GPS, radar, etc.  The mariner must be attentive to the source and accuracy of the position fixing device utilized by the ECDIS.
                                                        
3.  Information Overload
The mariner is cautioned to be wary of information overload and a very cluttered display screen. Information overload and a cluttered screen seriously degrade navigation safety for the mariner and could result in a "technology-assisted incident".

  1. Familiarization of ECDIS
A mariner must invest time and effort to mastering the device prior to his first navigational watch.  This will be crucial to the navigation safety of the vessel in the event paper charts are not required or available on the vessel.

Q. Identify, describe and explain
     IALA System of Maritime Buoyages
     1. Region A
     2. Region B
     3. Emergency Wreck Marker Buoy

Q. Admiralty Chart Symbol and Abbreviations (NP 5011) 
     Identify and explain 


Q. Compass – explain
     1. Calculation – give simple exercise and demonstrate how to find the compass
          error

    2. Explanation
        An instrument used to indicate heading of the ship and to
        determine bearings. Two type of compasses:
         i.    Gyro compass.
        ii.    Magnetic compass.

Q. Compass Error
     The difference between in the direction indicated as north by the compass and
      the true north is compass error. In other words the difference between the
      compass north and the true north is the compass error. Compass error named
      East or West:

Q. Three methods determining compass error:
  1. Azimuth: true bearing of the heavenly body calculated at a given time in GMT.
  2. Amplitude: True bearing of the heavenly body calculated at a given time in GMT made when body is on the horizon, rising or setting.
  3. Transit: A bearing is one in which to conspicuous terrestrial object are in line, one in front of the other.

Q. Correction of deviation
     Following four provisions are provided to reduce the compass error(it can not  
     be totally eliminated)
  1. Flinders bar.
  2. Spheres (two numbers placed port and stbd).
  3. Heeling error magnets.
  4. Horizontal magnets- they compensate for the forward and aft and athwart ships components of the semi permanent magnetism.
  5. PEWRUS: It is an alternative to azimuth mirror. It enables the navigator to obtain bearings of shore object particularly when the line of sight of the azimuth mirror on the standard compass is obscured.  
Q. Gyro compass: Advantages
  1. Its reference point is true north.
  2. Can be connected to any amount of equipments which requires compass feeding.
Q. Disadvantages of Gyro Compass
  1. Complicated mechanical device.
  2. requires constant power supply.
        Note: Gyro compass error referred to high or low.

Q . Magnetic Compass
      Advantages:
  1. No mechanical moving parts.
  2. Does not require electrical power.
     Effected by two errors: deviation and variation.
     By using transmitting magnetic compass(TMC). It is possible to feed magnetic    
     compass to any number of equipment requires compass feeding.

Q. Steering
     Method of steering”(four methods):
  1. Automatic(auto pilot)
  2. Manual(by Helmsman)
  3. Remote steering (with extended cord)
  4. Emergency steering.
     Off course alarm: This equipment maintains a continuous watch on the  
     vessel’s course so that any break down of the Gyro compass or auto pilot is
     immediately brought to the notice of the OOW.
     A three second delay is introduced so that the alarm is not sounded by
     momentary contact during violent motion of vessel in heavy weather.

Q. Speed Measuring Device
  1. The stream log
  2. Dynamic pressure log.
  3. Impeller log.
  4. Electromagnetic log.
  5. Doppler log.


Q. Radar Plotting Exercise
     Demonstrate;

1.      The principle of radar plotting (AOW Triangle) - do simple exercise. (Demonstrate the Action by plotting / answer being taken in the situation given must be related to the application of ROR).

Q.  Rules of the Road (COLREG 1974)
         1.     Explain/ Word by word/ Understanding of ROR
         2.     Light and Shape
     
Q. The operational of Radar and ARPA
