Historically the Caen harbour was specialized in coal, iron ore and steel products.
After the 2nd world war the port activities have largely diversified : wood, agricultural and industrial bulk cargoes, heavy lifts… This is the period in which SOGEMAR’s associates have started their activities.
SOGEMAR was created in 2006 through the association of the two departments of the SOGENA and SDV (Bolloré) groups present in Caen. Since Agrial, the Chamber of Commerce as well Sea-Invest have joined the capital. In 2019, Martime Kuhn takes over Bolloré's shares.
