Bocimar is a company based in Temse, specialized in dry bulk. It is a wholly-owned subsidiary of Compagnie Maritime Belge.
Bocimar International has three wholly-owned subsidiaries,Bocimar Lux S.A., Bocimar Belgium and CMB Japan. Bocimar Lux S.A. has a wholly owned subsidiary, Bocimar Far East Holdings.
The house flag of Bocimar is shown on the CMB-Bocimar website as yellow with two thin blue stripes on top and bottom of the flag and a blue, seriffed "B" in the middle of the flag.
Brown's Flags and Funnels of Shipping Companies of the World (1995)shows the flag of is yellow with equal stripes on top and bottom of the flag and a sans-seriffed "B".
Blue and yellow are the traditional colours of Temse but there is no evidence of a link between those colours and those of Bocimar, although such a link seems to be very plausible.
