U-Boat Bases and Bunkers: Lorient: Keroman I and Keroman II U-Boat Bunkers were directly connected through a forty eight meter long traversing unit. U-Boats in the Keroman I docking pen would be lowered onto a special trolley that would be winched up a ramp onto the traversing unit which would shift laterally lining the U-Boat up with one of the five wet pens in Keroman I or one of the seven dry pens in Keroman II where it would be moved onto a second trolley and into the bunker. The entire transit between the two bunkers would take one to two hours from start to finish.
