The purpose of this research is to analyze a generic ECDIS training program (hereafter GETP) carried out by domestic institutions according to IMO Model Course 1.27 (hereinafter,‘ECDIS model course’) and to suggest an enhanced GETP for the prevention of accidents which are caused by a wrong use of ECDIS.
Firstly, this paper examined international and domestic regulations on ECDIS, electronic navigation chart as well as the current status of ECDIS installation on board domestic ships, and then investigated GETPs carried out in domestic institutions. Secondly, the contents of IMO ECDIS model course and domestic GETPs were examined in order to verify that the current ECDIS teaching contents fully satisfy the current needs of navigational safety. Finally, an enhanced GETP based on ECDIS model course has been suggested through the analysis of ECDIS-related accident cases and the reinforces of importance additional contents which need to be supplied to officers in charge of a navigational watch in GETP for the prevention of an marine accident.
The results of the research are as follows:
(1) It has been confirmed that GETPs run by domestic institutions follow ECDIS model course in terms of contents.
(2) It was analysed whether critical contents for safety navigation which are required by ECDIS Model Course, have been properly included in the current curriculum has been analyzed. A considerable number of factors related to the navigational safety was not found in the curriculum and it was thought to be risky in securing navigational safety. For example, some of the critical chart symbols such as dangerous wrecks, rocks and obstructions were not included, and isolated dangerous symbols which can be changed by safety contour line setting were not also specified.
(3) Regardless of the number of the education taken, similar accidents of ground have continuously occurred. This confirms that inadequate setting of ECDIS chart scale, inadequate symbolizations and settings making symbols unseen on the chart, has repetitively occurred.
(4) The potential errors of sensors such as GPS and AIS displayed on screen are also one of the causes of repetitive accidents
The solutions to these problems suggested in this paper are that the training based on ECDIS Model Course should be more practical and specific based on the analysis of repeated accidents related to ECDIS, rather than educating simple and repetitive handling techniques. Further, it seems to be very important to detail the followings in ECDIS Model Course and GETP.
- Selecting Standard Mode or Other Mode, which displays the symbol to show the set point.
- Contents about isolated danger symbol which is changed by configuring safety contour line.
- Education for S-52 critical symbol.
- Monitoring voyage planning and necessity of using right map scale.
- Marking the symbols considering navigation and surrounding area.
- Guidelines for effective safety function setting.
- Need for and familiarization of the LOP function.
- Stating the potential error of displayed sensor data
- The reason of why ECDIS should not be relied upon as the sole reliable aid to navigation
Since this paper covers ECDIS Model Course and domestic GETPs only rather than the whole scope of ECDIS training, additional research on this needs should be carried out in order to make ECDIS training more practical and effective. It will be done in the future study.
