Modern Integrated Navigation Systems (INS) integrate information obtained from various sensors and functions. Processed data are presented on the computer display generally with the aim to increase navigator’s situation awareness and to reduce his/her workload. The investigations described in the paper were carried out to assess the advantages of the new functionality of the test INS (e-Navigation enhanced Integrated Navigation System ee-INS), developed in the EU financed EfficienSea Project, that looks and works like a standard ECDIS. This new functionality implements ‘Exchange of Intended Route’ service. The experiment was conducted in a full mission ship simulator environment with 20 experienced mariners. The bridge layout without ECDIS ‘Exchange of Intended Route’ functionality, and bridge layout with this functionality implemented, was applied in research and its results enabled to carry out their comparison. The navigators’ workload was measured by NASA-TLX method. Navigators’ situation awareness in respect to other ship’s state and the final passing distance were utilized to evaluate safety of navigation process.
