Claim Text:
1. A system for reducing vortex-induced-vibration (VIV) in an offshore platform, comprising: an offshore platform having a hull; a truss of the offshore platform configured to be at least partially submerged below a surface of water, the water having a current flow, the truss defining a truss bay square area; and one or more side plates tangentially coupled around a periphery of the truss, the one or more tangential side plates having less square area than the truss bay square area, at least one of the side plates positioned on the truss to form an open space for water and being configured to allow the water to flow around at least two edges of the at least one of the side plates and cause water separation around the at least two edges when the offshore platform moves transversely to the current flow and reduce VIV in the offshore platform compared to a VIV in the offshore platform without the tangential side plates.
