ARCOPOLplatform aims to further improve maritime safety in the Atlantic area and reinforce the protection of the coastal regions from maritime pollution through the capitalization and upgrading of ARCOPOL and ARCOPOLplus outcomes. Specifically, ARCOPOLplatform will organise pilot actions addressing local authorities to support the implementation of Local Contingency Plans. Moreover, these plans will be improved by the inclusion of ARCOPOL deliverables (tools and guides on Hazardous and Noxious Substances - HNS) that will be presented at workshops, training activities (blended learning), road-shows and on websites. The singularities of Natural Protected Areas and post-spill environmental monitoring issues will be also considered. Similarly, ARCOPOL spill modelling tools will be upgraded, shared among regions and transferred to competent authorities through tailored training. Furthermore, all activities will contribute to the development of the Atlantic Technological Platform. This platform will act as a forum for public and private organizations dealing with oil and HNS spills. It will focus on the exchange of knowledge, the identification of technological offer and demand, and the development of public-private initiatives. The project will be developed by 15 partners from 5 countries of the Atlantic Area including research organisations as well as regional competent authorities.
