Created in 1971, the SMBI is a public establishment composed of the Brittany Region, the Department of Finistere, Brest metropole and the Western Brittany Chamber of Commerce and Industry. It main purpose is to be the forum for strategic governance of the port of Brest. As such, it is responsible to develop and manage the port development reference scheme. As part of the development of the Brest port area, it pilots different strategic and prospective studies that could lead to investment programmes to provide the port with high-performance infrastructures and industrial-port tools. The SMBI, for and by the actors it brings together, leads actions of economic exploration in the service of the valorisation of port spaces, including those being created on the polder of the port of Brest.
