ABSTRACT:
A device to capture, contain and collect hydrocarbon fuels such as gasoline and diesel before they can be spilled or leaked from the ventilation valve or fuel intake port of the fuel tank of a vessel and on to the surface of the water during fueling operations at marine fueling facilities. The device is formed as a low-profile box with a floor section and upright wall sections having stratified layers of a textile material and a solidifying polymer enclosed within a outer envelope of textile material. A seamed area at the center of the device with slits in the textile material allows the device to circumscribe the annular conduit of a device passing through the seamed area. The device is positioned to surround the external ventilation valve of the fuel tank of the vessel. Excess fuel that is expelled through the ventilation valve when the capacity of the fuel tank is reached during the fueling operation is captured and absorbed by the device. The device is also positioned over the intake port of the fuel tank of a vessel to capture and contain any backflow or overflow of fuel at the fuel intake port. The device can also be placed under containers, such as auxiliary fuel tanks for outboard motors, to capture, contain and solidify any fuel leaks or spills that may occur and preventing the fuel from being discharged overboard and into the water.
