Giant Steel Boxes News

Over three hundred ISORIA pneumatically actuated butterfly valves have been supplied by the KSB Group for use in the salvaging of the cruise ship Costa Concordia, which capsized off Giglio Island on January 13, 2012. The role of the 328 valves is to fill and vent tanks located in the sponsons (giant steel boxes), the first 15 of which were welded to the port-side hull to act as ballasting bodies when righting the wreck. At a later stage, these sponsons, together with another 15 to be installed on the star-board side of the cruise ship, will be flooded and used to stabilize the wreck.
