ECDIS EHO: Handling the ECDIS failure at sea

The meaning of navigational safety is changing together with everlasting evolution of technology on ships at high seas. The Electronic Chart Display and Information System (ECDIS) as a most recent breakthrough in shipping, changed drastically not only layout of the navigational bridges but also navigational methods and routines. The safety reasons dictate compulsory redundancy of ECDIS system, recognising its central role in modern day navigation. If a ship’s ECDIS back-up arrangement is realized by installation of second independent system, it is known as paperless ship. Duplication increases the reliability of the system, but even a duplication doesn’t guarantee full reliability of the system at all times. In emergency situation as ECDIS total failure, navigator should rely on company procedures and guidelines. The aim of research is to determine navigators’ response in case of ECDIS total failure, and to identify if their reaction is supported or guided by company procedures. The research is based on international survey in form of questionnaire conducted among wide spectra of ECDIS stakeholders. This paper analyses part of the questionnaire which refers to the behaviour of navigators in ECDIS failure emergency and seek for procedure clarification by respondents. Answers are presented and discussed, revealing certain drawbacks in failure response and procedures. Along with presented results, survey of practice among shipping companies was carried out, supporting the results of questionnaire. The findings are emphasized in concluding chapter followed by proposal for further research and activities.
