Accidental water pollution involving HNS that behave as gases or evaporators can pose significant risks to both the environment and public health, particularly when located in ports or coastal waters. Due to their potential to form toxic gas clouds, it is of primary importance to provide accurate information on these substances to help defining appropriate response techniques. Moreover, if an incident occurs in areas where multiple administrations, regions, or even countries are involved in the response, effective cross-sectoral information exchange becomes crucial. Yet, the flow of information between these entities is often not as smooth as necessary for effective response efforts. MANIFESTS Genius (From Gases and Evaporators risk assessment towards an Integrated management of sea and land pollution incidents) aims to strengthen preparedness and response capabilities for integrated management of coastal water pollution. The main focus will be on the release of HNS, including alternative fuels such as HVO, ammonia, methanol and LNG, which could form a toxic gas cloud and potentially drift towards the shoreline and impact local communities.
Two scenarios will be considered:
1) a subsurface leak from a pipeline and
2) a leak at water surface from a port fueling station or a coastal facility. The project outputs will include the creation of operational guidelines and the upgrading of the MANIFESTS DSS, new experimental data on the behavior and impacts of HNS, good practices and recommendations to improve emergency plans for refueling stations that will work with new propulsion energies (methanol, ammonia…) as well as for coastal industries that use ammonia in their cooling system, and the establishment of intervention protocols at cross-sectoral scale. Bespoke training materials and exercises will be designed to transfer knowledge and decision-making tools developed in MANIFESTS Genius and other relevant EU and national projects to target stakeholders.
