During the construction of an extension of the harbour at Rostock, German Democratic Republic, for handling general cargo, a 1.2M.m3 hydraulic fill has been compacted by the Vibro-Wing method down to a maximum depth of 15m. The extension consists of a 1,250m long wharf constructed of precast concrete caissons and anchored sheet pile walls and a 25,000m2 storage area designed to carry a uniformly distributed load of 300kPa. Within the area are also several portal cranes and a number of warehouses. The method has also been used below water to compact the sand beneath the concrete caissons.
