ABSTRACT:
An oil spill containment collar system for aquatic vessels. A deployable floatation collar and apron apparatus automatically surrounds the periphery of the vessel to be contained. This continuous collar only takes a few minutes to become full functional. The collar may be stored either inboard or outboard of the vessel's gunnel about the deck. In the version of the embodiment which stores the collar inboard of the gunnel, the collar is lowered into the water by a gear or spring-torsion driven pivot arms that lift the collar from the deck area and up over the gunnel. the collar is inflated after lowering over the gunnel, encircling the entire vessel, and giving vertical support to an attached apron. In the outboard version, the collar is automatically released from a container and inflated by compressed gas means. The collar is provided with secondary floatation means to ensure its buoyancy. In both versions, the top edge of the apron is maintained level with the surface of the oil spill, by means of the attached and inflatable collar.
