RARDAR/ARPA (Operational and Management Level0 (STCW A-II/1. A-II/2)

The course is conducted in accordance with the minimum training standard requirements of STCW ’95 in Table A-II/1 and is based on the guidance on training in radar observation and plotting and in the operational use of ARPA in Section B-I/12 and on the guidelines of IMO Model Course 1.07.The course provides training in the basic theory and use of radar and is principally intended for candidates for certification as officers in charge of a navigational watch.

The course is essentially practical and consists of a series of exercises performed on a radar simulator with two or more own-ships and a number of others controlled by the instructor. Each exercise will involve observing the movement of ships seen on the RADAR, recognizing those presenting a threat of collision and taking action to avoid collisions. Trainees will act either as master or as an observing officers for the exercises and will change roles to allow each to turn in command of the ship. 

Course Objectives:

A trainee successfully completing this course will be able to recognize when radar should be in use; will select a suitable mode and range setting for the circumstances; will be able to set the controls for optimal performance and will be aware of the limitations of the equipment in detecting targets and in terms of accuracy. When within range of the coast, the trainee will be able to compare the radar display with the chart, select suitable conspicuous land targets and use these targets to fix his position. The trainee will also be aware of the need to maintain a continuing plot of ship targets which may pose a potential threat of collision; and trainees will be able to derive from the plot the necessary information about other ship’s courses, speeds and nearest approaches to enable action to be taken in ample time, in accordance with COLREG to prevent a close-quarters situation arising.

Entry Requirements:

  • Candidate must be above 18 years
  • Posses Valid Seafarer Medical
  • Valid Means of Identification
  • 2 Recent Photographs
