1. A floating security barrier, comprising: a) a plurality of buoys floating on a water surface and positioned in spaced apart orientation to form a partially above water surface perimeter around a marine platform to be protected, each buoy having an upper portion spaced above the water surface, a middle portion at the water's surface, and a lower portion below the water surface; b) a plurality of trusses, each spaced above the water surface, each truss spanning between the upper portions of a pair of buoys, each truss occupying a generally vertical plane and having a truss upper end portion and a truss lower end portion that is below said truss upper end portion, both said truss upper and truss lower end portions positioned above the water's surface; c) a connection that joins each truss at its end portion to a buoy, the connection being above the center of gravity of the truss; d) a curtain that extends downwardly from each truss, spanning between the truss and the water surface area; and e) wherein a portion of said curtain remains above said water surface to define an above water surface barrier between said truss lower end portion and the water's surface.
