With the increased presence of off-shore wind farms, off-shore production and processing facilities, new risks have also emerged over the past decades. The previous large-scale ship and off-shore accidents, such as Erika (1999), Prestige (2002) and Deepwater Horizon (2010) have demonstrated that e.g. oil spills can have disastrous impacts on the marine and coastal ecosystems (Venesjärvi R., 2016), and they can cause also significant economic losses (Yamada Y., 2009). In addition to the accidental spills, there are also operational spills, which are small, but frequent, intentional or inadvertent spillages in the sea due to ship operations (Neves A. et al., 2015). 1. Introduction To be prepared and to respond to different kinds of spills, states have implemented various national mechanisms for pollution in the maritime domain, including activities that are often embedded in regional cooperation frameworks clustered around certain sea areas. For instance, within the frameworks of the Helsinki Convention, the Bonn Agreement and the Barcelona Convention with the REMPEC, these activities include, e.g. adoption of operational procedures between the Contracting Parties, combating exercises for testing the regional cooperation in practice and risk assessments of designated sea areas. To summarize, the importance of effective risk management within the context of Pollution Preparedness and Response has been recognized both in national and regional level in Europe and worldwide. To support the risk-informed decision-making processes of Pollution Preparedness and Response authorities, several risk assessment tools and techniques have been developed during the past. To identify gaps in the existing open source risk assessment tool selection, fill these gaps, and integrate the tools in a structured manner, the Helsinki Commission (HELCOM) initiated a project to develop a freely available toolbox, known as the OpenRisk Toolbox. This is a set of tools and techniques especially for identifying hazards and analyzing risks of maritime activities. It is focused on accidental oil spills from maritime transportation, where regional cooperation would be required. While several of the currently available tools focus exclusively on the accidental oil spill risks related to maritime transportation, the toolbox is envisaged to be open, so other methods can be included to address risks from other maritime or off-shore activities. This paper briefly introduces the OpenRisk project, provides an overview of the OpenRisk Toolbox, and outlines future directions.
