MIMIC (Minimizing risks of maritime oil transport by holistic safety strategies) project analyzes the cost-effectiveness of alternative measures to reduce the risks and consequences of oil spills in the Gulf of Finland. A model has been developed that assesses the likely annual numbers of collisions and groundings and the consequent leakage, in relation to scenarios for oil transportation for the future. The model also estimates the capacity for oil recovery, and the length of oiled coastline after the recovery activity. The model evaluates whether it is more cost-effective to use resources for the Enhanced Navigation Support Information system (ENSI), compulsory pilotage, the improving of the crashworthiness of ships, or for simulation tools (Smart Response Web/Boris2) that inform where the most environmentally sensitive areas are and that can thus guide oil combating. The purpose of the model is to help the authorities in deciding which measures to implement.
