Abstract
An improved containment barrier or boom having a flotation means and a skirt section dependent therefrom. The boom may be wound around a reel for storage, and deployed from the reel as required. The flotation means comprises a flexible, longitudinally elongated tubular member, having a cavity extending throughout the elongated length thereof. A resilient, generally spring-like member having helical coil means is provided in the tubular member. The spring-like member extends substantially longitudinally throughout the length of the tubular member, and the helical coil means maintain the walls of the tubular member in a transversely expanded condition when the tubular member is deployed in the body of water. The spring-like member is resiliently deformable from the helical condition to a transversely flattened condition, when the tubular member is wound upon the reel for storage. The spring-like member, when in the transversely flattened storage condition thereof, has sufficient energy stored therein so that, upon deployment or unwinding from the reel, the spring-like member will move from its transversely flattened storage condition to its helical condition, thereby expanding the tubular member to its deployed condition.
