Abstract
A marine barrier gate includes a pleated row of buoyant panels movable between an expanded position and a retracted position, where the panels are substantially parallel. A first buoy is attached to a first end of the panel row, and a second buoy is remote from the panels when the panels are in the retracted position. The second buoy has a tow winch and cable attached to a second end opposite the first end, for moving the panels from the retracted position to the expanded position. The first buoy comprises a catenary winch and cable movably engagable with the panels and attached to the second buoy. When the panels are in the retracted position, the catenary winch sets a length or tension of the catenary cable such that it absorbs catenary loads on the barrier when the panels are moved to the expanded position by the tow winch.
