Work package 5 will develop and launch a strategic Net Environmental Benefit Analysis (sNEBA) tool for decision-making, to design an appropriate and fast national oil spill response strategy combining the right mix of interventions (e.g., mechanical recovery, in situ burning, chemical dispersants and/or bioremediation). The matrices outlined and presented in this deliverable D5.4 shall serve as a compliment to the sNEBA tool to answer the question “Can we?” when evaluating different oil spill response methods. The operational requirements included for assessment are categorized as operational window (time window, weather window and ice conditions) and resource logistics (equipment, personnel and transport). Matrix Z1 is a generic compilation of basic operational requirements for each response method. The operational probability, i.e. the probability that the specific method can be used for a specific oil spill scenario, is assessed in Matrix Z2. The operational probability is expected to give guidance in selection of response method, where an OSR method with high operational probability is more likely to be efficient for a specific oil spill scenario. The time window will affect the possibilities for a successful operation. If the needed resources cannot be made available at the site within the time window, the specific OCR can be disregarded.
