of the ship is noteworthy, as it had storage tanks with a capacity of nearly 36000 m³ volume built into its sides and the unusually large double hull, allowing it to be used also as a product tanker. The ships were later purchased by Military Sealift Command. Finnish state-owned shipbuilding company Valmet built two barge carriers largely based on the Sea Bee system for the Soviet Union in Vuosaari Shipyard in the late 1970s, and . Of these, Yulius Fuchik was featured in a prominent role in the novel Red Storm Rising by Tom Clancy, where it was modified to masquerade as Doctor Lykes. Technical data BACAT system A Danish project with the name BACAT (Barge-Catamaran) was introduced at the end of 1973. It was used for the transport of several hundred thousand metric tons of load between northern Europe and Great Britain. The system was similar to the Sea Bee, but the lighters were smaller and had an individual load-carrying capacity of only 140 tons. Technical data BACO System 1979 saw the introduction of the BaCo system, newly developed by Captain H. Mönke and Thyssen Nordseewerke, in which the carrier could transport barges in addition to standard shipping containers, therefore the name BaCo. In addition, the barges were floated into the flooded hold through bow doors, akin to how ships enter a floating dry dock. The hold could be made watertight by closing two vertically foldable inner doors and two large outer doors; water in the hold could be pumped out during sea passage. The deck was suited for the stowage of containers, for which a movable gantry crane was provided. The BaCo barges were relatively large compared to the LASH barges, having a deadweight of 800 t, whereby the max. draught was very large with 4.15 m. The BaCo beam of 9.5 m corresponded to the standard beam of European inland waterway transport barges, so that also four Europa barges of Type I could be stored instead of the 12 Baco barges. The container capacity was 652 TEU In total three Baco Liners were built between 1979 and 1984, named Baco Liner 1, Baco-Liner 2 and Baco Liner 3. Owner was the Baco-Liner GmbH Emden, founded by the shipyard, the Rhein-, Maas- und See-Schiffahrtskontor GmbH (RMS) as well as Rhenus-WTAG, Dortmund. Operator was RMS. The BaCo barges were among others built by Cassens-Werft in Emden. The Baco-Liners were
