Abstract
The increasing complexity of activities in the maritime domain raised new challenges to all coastal states. In the case of Portugal, it is also required to promptly react to the needs of Portuguese flag vessels around the world. In line with this, the Portuguese Navy developed a study, focused on the requirements assessment for an enhanced Maritime Situational Awareness (MSA) system. The study started with a review of SA concept models to better understand and analyse the MSA concept used by Portuguese Navy. Maritime Situational Awareness is a concept that has been widely discussed in the maritime surveillance field; on the other hand there are some authors with well-established definitions of Situational Awareness (SA). This paper address three SA concepts and associated models. The first presents an embedded world view with an ecological approach, the second, focuses on a reflective quality with an activity approach and the third focuses on the structure of information processing. These models are later related with the current MSA model used by the Portuguese Navy, considering the strengths and weaknesses of each model. From this comparative analysis, an integrated methodology is proposed to determine requirements for the MSA system of the Portuguese Navy Operational Centre (COMAR).
