ABSTRACT:
A skimming vessel is provided for collecting hydrocarbons or other floating materials, from the surface of a body of water. The floating vessel has an engine driving a prop and is provided with a skimming mode and a traveling mode. A dual skimmer system is provided for skimming the surface of a body of water for collecting hydrocarbons from the surface of the water. The surface of the water is skimmed to capture the floating hydrocarbons by drawing the water through the skimmer with the vessel drive propeller when the vessel is in its skimming mode and to block the passage of water through the skimmer when the vessel is in its travel mode, so that the vessel drive is used to improve the removal of hydrocarbons from the surface of the body of water. The vessel has a passageway or tunnel formed in the bottom thereof for the passage of water and has the prop mounted in the tunnel for drawing water through the tunnel to pull water into the skimming system. The tunnel is blocked and the position of at least one skimmer is changed to switch the vessel into a traveling mode for more rapid movement through the water. One or more tunnels can be utilized as desired in the bottom of the vessel.
