Pontoon bridge Pontoon bridge A pontoon bridge (or ponton bridge), also known as a floating bridge, uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load they can carry. Most pontoon bridges are temporary, used in wartime and civil emergencies. Permanent floating bridges are useful for sheltered water-crossings where it is not considered economically feasible to suspend a bridge from anchored piers. Such bridges can require a section that is elevated, or can be raised or removed, to allow waterborne traffic to pass. Pontoon bridges have been in
Cable fairing slide down the cable (until they “stack” at the aft end) without the use of the anti-stacking rings. Cable fairing A cable fairing is a structure attached to a towed cable designed to streamline the flow around the cable, primarily in marine environments. Cables are faired primarily for two reasons: (1) to reduce normal drag and thus achieve more depth for a given cable scope and speed; and (2) to eliminate cable vibration caused by vortex shedding, commonly known as cable strum. There are several major types of cable fairing: All cables (faired or unfaired) have hydrodynamic loading functions. These
