This paper presents the preliminary results of a pilot study in an ongoing project that analyzes past maritime security incidents using graphic representation models. This pilot study aims to identify some of the active and latent conditions that allow maritime security incidents to occur, to conduct a macro-level analysis of security incidents, and to determine the feasibility of adapting the AcciMap as a tool for maritime security management. The method employed in this pilot study is the application of the concepts and principles formulated by Rasmussen and Svedung and the adaptation of their AcciMap graphic representation model to the 1999 hijacking of the general-cargo vessel Alondra Rainbow. The materials used are information gathered from official and journalistic investigations conducted into the security incident. As part of its results, this paper presents a SecInciMap of the hijacking and identifies actors and latent and active conditions relevant to the incident. The paper’s preliminary conclusion is that the adaptation of the AcciMap to the context of maritime security is feasible and could play an important role in a proactive maritime security regime.
