The present IMO model course is mainly intended for the ship officers willing to be certified and chief mate and master on vessels having a gross tonnage of five hundred tons or more. All entrants should have already completed a pre-requisite course on the minimum standards that is required for certification as the officer-in-charge of a navigational watch on the vessels of same size.
In contrast to this Model Course 7.03, the present course is covering the navigation, cargo handling and controlling the operation of the vessel and people care not at the operation but at the management level. In general, the declared purpose of all IMO model courses is to help all training institutes together with their teaching staff to better introduce ad properly organize the new courses and also improve the existing materials.
Again, the Table A-II/2 of the STCW Convention is being referred. The background technical knowledge supporting the tasks, relevant duties and associated responsibilities are listed in the appropriate sections of the training program and are more or less similar to the Model Course 7.03; however there are some differences and you would better go through the contents of each publication to have a clear picture.
