Syftet med denna studie var att utforska nautiska befäls attityder till larmen de kan ställas inför på sin brygga och den eventuella kausaliteten. Tidigare forskning inom larm och forskning inom optimering av brygglayouter presenterade ett problematiskt fenomen vilken av Papastavrou och Lehto kallas för cry-wolf. Detta fenomen beskriver att operatörer av system med larm, till exempel sjöfartsofficerare, tenderar att ignorera larmen om de utsätts för en hög frekvens av larm, denna höga frekvens kallar Al-Dabbagh och Tongwen för alarm-floods. Denna studie kommer fram till att cry-wolf fenomenet existerar ombord det fartyg studien utfördes på. Datainsamlingen utfördes med den kvalitativa forskningsmetodiken, främst genom semi-strukturerade intervjuer. Dessa intervjuer kompletterades sedan med ostrukturerade observationer vilka utfördes under en nio dagar lång fältstudie. Studiens primärdata analyserades genom innehållsanalyser och detta gjordes ur det hermeneutiska perspektivet. Studien fann att befälen tenderar att ignorera larmen om larmen inte klassas som nödlarm. Vidare presenteras två potentiella lösningar som ämnar ge tillbaka den tyngd larmen borde associeras med. Utöver detta presenteras också en hypotes vilken syftar till att ta reda på om ett givet fartyg påverkas av cry-wolf fenomenet. Denna hypotes måste valideras innan den kan godtas som gångbar för sjöfarten som helhet. / The main purpose of this thesis was to explore nautical officer’s attitudes towards the alarms they may encounter on the bridge and the eventual causality between the officers and their actions concerning the alarms. Earlier research into alarms and research regarding optimization of bridge-layouts presented a problematic theory which Papastavrou and Lehto call cry-wolf. Wherein the operators of systems, or ships, with advanced alarms tend to ignore the alarms if they are subjected to a high frequency of alarms, or alarm-floods as Al-Dabbagh and Tongwen calls it. This study shows that, on board the vessel which the study was conducted, the cry-wolf phenomena exist. The study was conducted on board a Swedish vessel from the hermeneutical perspective. The data collection was done with the qualitative method, primarily through semi-structured interviews and these were then enriched with data from unstructured observations which were made during a nine-day stay aboard said vessel. The collected data has been analysed through content analysis from the hermeneutical perspective and the study reveals that the officers tend to ignore the alarms, unless they are classified as emergency alarms. This study proposes two potential fixes for how to make the alarms less overwhelming and how to give back the importance of the alarms. Furthermore, the study presents a hypothesis which aims to find whether or not a given vessel is subject to the cry-wolf phenomena. This hypothesis needs to be proven in future research before it can be proclaimed as a valid hypothesis.
