Survey and Analysis of User Opinion for the Review and Modernization of GMDSS and Implementation of e-Navigation

Abstract

Global Maritime Distress and Safety System (GMDSS) equipment and Electronic Chart Display & Information System (ECDIS) are typical equipment which help seafarers to obtain information for ship`s safe navigation. In this study, a survey on using of GMDSS equipment and ECDIS was conducted on a total of 260 ship masters and crew who have been working on ocean-going vessels. The subjects were asked about the usage, and level and reason of satisfaction or dissatisfaction of GMDSS equipment and ECDIS, the leading navigational system from which they receive information. The survey showed that the third- and fourth-most frequently used equipment, MF/HF and INMARSAT (telex), were deemed to be the second- and third-most useless equipment. It means that the frequency of device usage is not proportionate to the level of navigational safety. Especially, `ease of device use (42.3%)` and `necessity of the provided information (50%)` were highlighted as factors increasing the level of satisfaction with the system. The survey result shows that ship safety cannot be realized by only adopting advanced systems, technology and services. It emphasizes the need to consider the level of `accessibility and appropriateness of the information` and `ease of device use`. Discussions implemented by the IMO on various policies and regulations are aimed at securing ship safety. In order to achieve the goal, such institutions should be validated by end-users and relevant studies should be conducted.
