Abstract
Seapack. Pack which can be attached to the deck of a support vessel comprises a deflated anti-pollution boom comprising a continuous water inflatable water chamber, a driven roller which can pull the barrier aboard the vessel and cause its deflation, means to attach a first end of the barrier to the vessel, means to inflate the gas chamber and means to inflate the water chamber.
Claims8
A method for deploying an inflatable, flexible, floating barrier comprising a continuous gas-inflatable gas chamber in side by side relationship to a continuous water-inflatable water chamber from a support vessel, which comprises securing a first end of the barrier to the vessel;
- connecting gas inflating means to said first end of the gas chamber;
- connecting a venturi device to said first end of the water chamber;
- positioning the open end of said water inflatable chamber under water so that by pumping a small quantity of water into the chamber at high pressure through the venturi device thereby entrains large volumes of water from the surrounding sea into the water chamber;
- and discharging the barrier progressively from the vessel while inflating at least the gas chamber so that the barrier does not sink;
- causing relative separation between the vessel and the discharged barrier so that the latter takes up a closed curved shape away from the vessel;
- passing the second end of the barrier to a second support vessel or an anchoring means;
- moving the barrier to its desired position and maintaining the gas and water inflation of the deployed barrier.
A pack, suitable for attachment to the deck of a support vessel, comprising a deflated barrier of neoprene coated nylon fabric comprising a continuous gas-inflatable gas chamber in side by side relationship to a continuous water-inflatable water chamber, said barrier having an attachment plate fitted to the end thereof by which it is to be secured to the support vessel, a driven roller that can pull the barrier aboard the vessel and cause its deflation, means to attach a first end of the barrier to the vessel, means to inflate the gas chamber and means to inflate the water chamber.
