Abstract

A pile wrapper comprises a flexible sheet (2) of parallelogram form with stiff but not completely rigid members (3) along a pair of opposite edges proud of the side of the sheet to be exposed. This side also has flexible ribs or vanes (4) parallel to those members. When wrapped around a pile (1) the members (3) are squeezed and fastened together, forcing those members into a helical configuration, similar to that adopted by the ribs or vanes (4). Water flowing past the pile is diverted towards the longitudinal direction of the pile, reducing the tendency to vortex induced vibration.
