Vortex shedding strake wraps for submerged pilings and pipes

A combination of a piling and piling-protecting and vortex-shedding wrap panel formed of stretchable and flexible elastomer sheet material, dimensioned for wraparound engagement encircling the exposed outer surface of a substantially vertical submerged pipe or piling having a longitudinal axis, comprising:

• a quadrilateral sheet having two elongated parallel edges, and having an outer face and an inner piling-facing surface,
• a first elongated clamping means arrayed along the first of said parallel edges,
• a second elongated clamping means arrayed along the second of said parallel edges,
• said clamping means comprising cooperating arrays of apertured members provided with spaced apart fastening apertures positioned for cooperative alignment when the quadrilateral sheet is wrapped around a piling and said elongated clamping means are brought into juxtaposition,
• said outer face having protruding outward therefrom a plurality of elongated flexible rib-strakes extending along the length of said quadrilateral sheet, which are deployed when said sheet is wrapped around a piling,
• and fastening means extending through said fastening apertures and holding said clamping means in clamped alignment in said juxtaposition,
• whereby lateral aeolian vibrations caused by vortex streets Produced by horizontal currents flowing past the submerged pipe or piling in directions perpendicular to its longitudinal axis are minimized or eliminated.
