A load reduction device is mounted on a piling to reduce flow-drag created by fluid flowing on and past the piling. Upper and lower collars engage the piling to support and guide a bi-directionally tapered hydrodynamic foil having a tapered leading vane portion and tapered trailing vane portion extending between the collars. The bi-directionally tapered hydrodynamic foil is rotatably supported in the collars to permit its rotation about the longitudinal axis of the piling. The tapered trailing vane portion has an extended tapered shape to orient the lead...
1. A device to reduce load created by flowing fluid on a piling comprising: a bi-directionally tapered hydrodynamic foil having a traverse tube sized to fit around a piling in a spaced-apart relationship with respect to said piling, said hydrodynamic foil having a tapered leading vane portion located on one side of said traverse tube and extending to diametrically opposed sides thereof, said hydrodynamic foil having a tapered trailing vane portion located on the opposite side of said traverse tube as said tapered leading vane portion, said tapered lea...
