Objective

  • Navigation is the art and science of safely and efficiently directing the movements of a vessel from one point to another.
  • Piloting uses water depth and visible references, while dead reckoning uses courses and distances from the last known position.

Learning outcome

  • Navigation is the methods used to learn where someone is and how to go to another place. Since this is easy when landmarks are visible, the word is often limited to the methods ships or aircraft use.
  • Navigation and Seamanship and Types of Navigation
  • Earth and its coordinates
  • Navigational Aids and Bearing instruments
  • Sounding and speed measuring
  • Signals and Aids to Navigation
  • Sea Safety and Regulations

Course Syllabus

 

Module I:                                                                                                    

  • Principles of navigation –terms and definitions, finding positions and method of position fixing
  • Magnetic Compass-parts and functions, cardinal, inter cardinal, three letter and lay points, pelorus and azimuth mirror, method of observation.
  • Sextant -parts and functions, finding adjustable and non-adjustable errors and principles and use.
  • Hand lead line –construction and markings and method of taking soundings. Types of speed logs –patent log, impeller log,
  • Types of marine charts, Mercator and gnomonic projections great circles and rumba lines, chart collections and chart readings, chart observation and fixing positions.
  • The IALA-buoy age systems, cardinal and lateral marks, meaning of shapes, colours and lights top marks and explanation of approaching, international code of signals, flag signals morse code and storm signals general system, brief system and extended system ,storm signals stations, Fog signals, types and methods .
  • Distress signals, methods, types and communication international regulations for preventing collision at sea and recognition of lights and shapes at sea.
  • Observation of radar and parts and functions of radar, aneroid barometer, parts and functions of echo sounder, and sonar.
  • Observation of GPS
  • Practice
  • Integrated series of formal lectures, videos, group discussions and tutorials.

 

Module II:            

  • Principles of seamanship- Causes fire at sea, fire prevention on board the vessel and method of firefighting at sea and recommended firefighting appliances.
  • Lifesaving appliances –life jackets, life buoys and method of operations and contents
  • SART and EPIRB.
  • Observations of storms, formation of storms and method of locating the eye of the storms and method of escaping from the center of the storms as per buys ballet law.
  • Preparing vessel to face heavy weather.
  • Temporary repairs for leaks constructions of steering system and rigging emergency jury rudder .
  • Types of anchors and their applications.
  • Selection of suitable anchorage, procedure for anchoring anchor watch and procedure to combating dragging of anchor, method of standing moor and running moor, open moor berthing procedures, axial thrust, transverse thrust mooring and securing the vessel to the jetty rigging fenders and gangways , and method of leaving vessels from the berth.
  • Navigation is the methods used to learn where someone is and how to go to another place. Since this is easy when landmarks are visible, the word is often limited to the methods ships or aircraft use.

Module III:

  • Anchoring, coming alongside the berth and leaving.
  • Practicing the different types of knots and wire splices,
  • Use of magnetic compass, GPS, Echo-sounder.
  • CHART WORK-Finding positions by latitudes and longitudes by position lines by cross bearing, horizontal sextant, angles, vertical sextant angle and by running fix, finding position by speed, distance and time findings set and drift of current and findings course made good speed made good and steering course and finding position by counter acting the current observation of RADAR .
