Abstract
The disclosure provides a system and method of reducing vortex induced vibration (VIV) with a plurality of tangentially disposed side plates having an open space on both faces transverse to a current flow of water. The side plates cause water separation around the plates with transverse VIV movement of the platform caused by the current flow against the platform, and the tangential side plates resist the VIV movement of the platform from the current. The side plates can be disposed tangentially around a periphery of an open truss structure below the hull of a spar platform. In another embodiment, the tangential side plates can be disposed tangentially away from a periphery of a hull to form a gap with an open space between the plates and the hull.
