ABSTRACT: Modular Integrated Navigation Systems (INS) according to the revised IMO performance stan?dards on INS combine and integrate the validated information of different sensors and functions and allow the presentation on the various displays according to the tasks. The aim of the investigations discussed within this paper was to assess the advantages of an INS design compared to a traditional bridge layout with respect to the execution of collision avoidance and route monitoring tasks. The Situation Awareness Global Assessment Technique (SAGAT) approach was applied to assess Situation Awareness (SA) during these operations while bridge design and out of window visibility were manipulated. Additionally, workload was measured by NASA-TLX with its six subscales. The experiment was con?ducted in a full immersive simulation environ?ment with 26 experienced mari?ners. The results indicate that SA is significantly higher with the INS bridge design in the reduced visibility condition compared to the traditional bridge design. Also, tendencies were found that workload and subdimensions are influenced by bridge design and visibility conditions.
