Chabahar Maritime University has started radar/ARPA simulator training course since 2004 and the training has been carried out fully comply with STCW95 Convention and the IMO model course. According to the improvement in navigational technology, the reducion of Navigational Aids as two credits of the latest BSc sylabus for future officers on board ships will be discussed through this article in depth. In addition to the above, the author attempts to describe the AIS (Auomatic Identification System) which is defined by IMO and has been adopted by the latest revision of SOLAS chapter V. In fact, the AIS is part of ship’s radio station and is surveyed together with radio installation. The AIS training is going to be taken place from next semester at Chabahar Maritime University in order to improve the skill of the trainees in order to rely the information provided by AIS. 1 RADAR/ARPA SIMULATOR TRAINING COURSE Based on Section A-1/2 of STCW95 Convention, training of marine simulator regarding Radar and ARPA Courses are compulsory for future officers and masters on board ships. According to the above sction of STCW95 Convention, the following factors should be consideed: − be suitable or the selected objectives and training tasks and be capable of satisfying the specific assessment objectives; − be capable of simulating the operating cababilities of shipboard eqipment concrned, to the level of physical realism appropriate to tranng of assessment objectives, and include the capabilities, initiations and possible erroe of such equipment; − have sufficient behavioural realism to allow a trainee to acquire and a candidate to exibit the skills appropriate to the training and assessment objectives; AIS is abbrivated as Automatic Identification System which is being used to concur with the IMO standards (MSc74,(69), annex3). Indeed, IMO reccomended that it is compulsory for all vessels to be equipped with AIS until July 2008. As Cap.Holder said that we might discover that AIS could have a positive or ngeative influence on collissions. Its impact will be positive if it aids mutual recognition, enhances the application of the correct rules and proides unambiguous agreement of further action. It will also be posiive if AIS can identify ships in clutter or hidden behind bends. − provide a contolled opearating environment, capable of producing a vriety of conditions, which may include mergency, hazardos or unusual situations relavant to the training and assessment objectives; − provide an interface through which a trainee can interact with the equipment, the simulated environment and, as appropriate, the instructor; and − present an instructor, and assessor the ability to control, monitor and record exercises for the effective debriefing of trainees and effective assessment of the performance of candidates. In addition to the above essential simulator training items, instructors and assessors should consider some more factors in order to assess the ability of candidates based on his/her competancey level. 2 AUTOMATIC IDENIFIACTION SYSTEM In fact, AIS offers the following information which can be categorized as three main group: a). Constant information suach as name of ship, IMO no, length and breath of ship, type of ship.b). Voyage information such as draft, type of loaded cargo, destination and ETA, etc. c). Changed information such as time, compase course, position, ship speed, sailing condition, etc. David Patraiko pointed out that wihin a decade, ships could have to fit VDRs, AIS and increasingly ECDIS, wih a proliferation of different designs for similar equipment.
