House flag of GBS
General Bunkering Services (GBS) is an inland bunkering firm founded in Antwerp in 1998 by Mr E. Vermeylen through a takeover of another firm and four vessels. GBS now operates seven tankers, most of them double-hulled and named after composers. Furthermore the company is active in mineral oil freighting and has recently expanded into container transportation by road.
The house flag of GBS, as spotted flying over the Beethoven, is horizontally divided red-white-blue (1:2:1) with the black initials "GBS" (no serifs) in the middle stripe.
