The project objective is the development of a web portal offering access to ship owners, policy makers and the scientific community. The portal will be used to (a) suggest vessel and environmentally optimal safe route planning (b) deliver real-time alerts for ships and (c) support policy recommendations. The portal will be based on historical and real-time maritime data, including real-time information for ship position and speed, weather and sea forecasting and land and sea location. Through this web-portal, the project aims directly to reduce the risk of a ship accident and consequently to contribute in the protection of the Aegean Sea. At the same time, the web-portal aims to bring profit to the enterprise partners of the project, mainly by proposing accident risk reducing services to ship owners. The research partners will be given a unique opportunity to advance their methodologies for handling and analysis of huge quantities of heterogeneous spatiotemporal streaming data to assess risk in real time. Any lessons learned from the analysis of the high risk ship traffic of the Aegean Sea are likely to have direct and immediate relevance to policy makers and stakeholders globally.
