Vortex shedding strake wraps for submerged pilings and pipes

Abstract

Flexible elastomer wrap panels stretched and clamped encircling submerged pilings, risers and pipelines are coated to resist degradation by any form of marine life, and incorporate an interior pile-facing felt layer impregnated with a corrosion inhibiting and biocidal gel, providing long term protection for pilings and like submerged objects. The wrap panels present radial rib-strakes protruding outward from the piling and extending along the piling in a longitudinal direction, either vertically, parallel to the vertical axis of the piling or pipe, or slanting helically, reducing or eliminating aeolian vibration induced by flowing ocean currents causing vortex formation. In some embodiments, the wrap panels and strakes incorporate a marine growth inhibiting filler material.
