On 23rd February 1981, Cedre entered its new 750 m² premises, built on the site of the Centre océanologique de Bretagne of the Centre National pour l’Exploitation des Océans (CNEXO). This represented a 5 million Franc investment. In this building, Cedre had some twenty offices, a multipurpose room, a resource centre, an archive room, an operational response centre, an analysis laboratory, a workshop and a store. It accommodated a team of 27 people by the end of the year. In addition, technical trial facilities with a man-made beach were set up at the port of commerce, on the other side of the city. Cedre was called upon 24 times that year in response to accidents and incidents.
