Development of a Concept for Bridge Alert Management

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.
