Investigations into shipborne alarm management - Conduction and results of field studies
Safe navigation, including collision and grounding avoidance, is the main task of the navigating officer in charge to ensure the safety of sea transport during a ship's voyage. Modem ship bridges are highly-automated man-machine systems. With the enlarged number of systems and sensors onboard, and the increase of automation a proliferation of alarm signals on the bridge is associated. Field studies were performed on board of ships to investigate the situation with respect to the occurrence of alarms and its handling by the bridge team. Within this paper the conduction of the investigations, the used methods, and selected results for two samples of field studies will be presented. An outlook for a future alarm management onboard is given. The investigations were partly performed under the framework of a national Research and Development project funded by the German Ministry of Transport, Building and Urban Affairs, and under the European MarNIS - project, funded by the European Commission, Department for Energy and Transport.
