Q.
Navigation In Coastal Waters
Following
considerations while preparing passage plan
- Taking in advise /recommendation from sailing directions
- Ships draft in relation to available depth of water
- Effect of Squat on under keel clearance in shallow water
- Tides and currents
- Wx particularly in areas more susceptible to poor visibility
- Available navigational aids and their accuracy
- Which positions fixing methods to be used
- Day / Night time passing of danger points
- Traffic likely to be encountered flow type and volume
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:
- Routing system
- TSS
- Traffic separation zone or line
- Traffic line
- Round about
- Inshore traffic zone
- Two way route
- Recommended track
- Deep water route
- Precautionary area
- Area to be avoided
- Established direction of traffic flow
- 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:
- 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".
- 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:
- Azimuth: true bearing of the heavenly body
calculated at a given time in GMT.
- Amplitude: True bearing of the heavenly
body calculated at a given time in GMT made when body is on the horizon,
rising or setting.
- 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)
- Flinders bar.
- Spheres (two numbers placed port and stbd).
- Heeling error magnets.
- Horizontal magnets- they compensate for the
forward and aft and athwart ships components of the semi permanent
magnetism.
- 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
- Its reference point is true north.
- Can be connected to any amount of equipments which requires compass feeding.
Q.
Disadvantages of Gyro Compass
- Complicated mechanical device.
- requires constant power supply.
Note: Gyro compass error referred to
high or low.
Q
. Magnetic Compass
Advantages:
- No mechanical moving parts.
- 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):
- Automatic(auto pilot)
- Manual(by Helmsman)
- Remote steering (with extended cord)
- 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
- The stream log
- Dynamic pressure log.
- Impeller log.
- Electromagnetic log.
- 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)

Explain/ Word by word/ Understanding of ROR
2. Light and Shape
Q. The operational of Radar and ARPA
Q. Respond to
emergency example ; collision, grounding, fire etc.
