ABSTRACT:
A collapsible, quickly deployable floating boom barrier comprises an elongated curtain-like partition of strong, flexible, impervious material supported in a substantially vertical position in the water by a plurality of outrigger-type flotation units spaced along the partition.
The partition is in the form of an elongated, flexible belt which has a smooth surface on the side opposite the flotation units, and the smooth side surface engages the material to be contained by the barrier.
The barrier has sufficient longitudinal flexibility to encircle an oil spill or a ship that might be unloading or loading oil, and the outrigger flotation units support the partition or belt at a height above the surface of the water which is approximately 1/3 to 1/2 of the partition width.
Each outrigger flotation unit comprises a frame and a float. The frame is connected to the side of the partition or belt for pivoting action about a vertical axis extending parallel and immediately adjacent to the side of the belt, and the float is connected to the frame for pivoting action about a horizontally extending axis. This articulation of the frame and float provides a self-stabilizing action of the outrigger flotation units. It also permits each float and frame to be folded back flat against the side of the belt to facilitate deployment of the floating barrier through narrow passageways such as between ships and piers. This articulation also permits the barrier to be folded accordian fashion for compact storage and transport.
