The current separation of communication systems and navigational systems on the ships bridge doesn’t meet the requirements of the e-navigation concept of the International Maritime Organization (IMO) for safe navigation to include all means and information in the decision making. Hydrographical, meteorolog-ical and safety related information is presented on the communication equipment without filtering or as print-outs solely. A task oriented integration and presentation of this information on the navigational displays will support the officers in their decision making and enhance the safety of navigation. The core element onboard for the integration is the INS (Integrated Navigation System) concept of the IMO where a task and situation dependent presentation of information is specified based on a modular concept. Information should be auto-matically processed, filtered and integrated in the navigational information systems to support the users in their tasks. To achieve this goal a concept for communication management was developed. An Applied Cog-nitive Work Analysis (ACWA) is conducted to identify requirements for the design of a communication man-agement system based on the cognitive processes of the operators. This paper describes the concept for com-munication management and, as a first result, gives the description of the domain of maritime communication that provides a basis for the identification of requirements for communication management in the framework of the e-navigation concept.

Modern ship bridges are highly-automated man-machine systems. Safe and efficient ship operations are dependent on the communication between humans and machines. This paper is dedicated to the general subject of integrated navigation and the specific field of the alert management on a ship's navigational bridge. It deals with investigations into the present situation on board of ships regarding the frequency and type of triggered alarms under real conditions. The conduction of empirical field studies is introduced and some of the gained results are presented and discussed. Finally the alert management concept of the performance standards for Integrated Navigation Systems (INS) is introduced and an approach for the reduction of CPA/TCPA alarm frequencies within INS/IBS is described.

Modular Integrated Navigation Systems (INS) according to the revised IMO performance standards 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 conducted in a full immersive simulation environment with 26 experienced mariners. 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.
