Navigation Safety Assessment in the Restricted Area with the Use of ECDIS

This paper presents an analysis of vessel safety parameters used in Electronic Chart Display and Information Systems (ECDIS) while navigating in restricted areas. Apart from defining priorities, a group of parameters, indispensable for safe navigation in restricted waters, is identified. The function of ship domain is proposed on the basis of safety parameters defined in the ECDIS system. This function may be utilized in the navigation decision support system that uses ECDIS data and be included as a new function in the ECDIS system.
