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.
