Since 1981, Cedre has had a storage facility in Brest's port area, developed during the Amoco Cadiz spill. These trial facilities were connected to the water supply, electricity grid and telephone network. Sanitary facilities were installed, a washing area created, the water-side area improved and an oil storage capacity and trial facility for pumping equipment built. Cedre was thus equipped with advanced facilities for conducting trials and practical training courses to match its experience. The pollution risk generated by the shipping of hazardous substances was assessed for each sea front. Among the drums washed up that year on the Breton shoreline were harmful products such as acetone, sulphuric acid and aniline oil.
