ABSTRACT:
Material containment apparatus and method for effectively containing spilt material floating in water around a structure such as an oil transport ship. Primary components include a protective openable storage housing attached to and encircling the ship above the water line, inflatable and multi-directionally expandable buoyant containment boom, a vertically extendable oil impervious curtain which hangs below the boom in the water, boom inflating and positioning arms to maintain a separation between the deployed floating boom and the ship, a vapor capturing curtain between the deployed boom and the ship above the spilt material, and a vent or burn-off stack to dispose of hazardous fumes which are captured under the vapor curtain from evaporating spilt materials such as oil. The boom, boom positioning arms, and curtains are stored in the storage housing as a complete structure ready for instant deployment. The invention includes controls and powered actuators allowing deployment of the equipment, once initially installed on a ship, around a spill by a single person within a matter of minutes. The invention also includes back-up structuring associated with most of the various primary components of the invention to render containment of a spill virtually fail-safe.
