  • Underwater pile cutting apparatus and method of use
    Patent number: 7121310
    Abstract: An apparatus for cutting wooden piles underwater and a method of use are disclosed. The apparatus has a frame and brace configured for engaging a pile. A pressure medium activated cutting device is connected to the frame and oriented at an angle such that a pile can be cut at a point below the bottom surface. The frame and brace are placed on opposite sides of the pile and connected to each other with a chain or cable. The apparatus has lines attached thereto and the other ends of the lines are attached to a boat or other flotation device. Using the disclosed apparatus to remove pilings causes significantly less turbidity than devices or methods currently available. Additionally, using the disclosed device also eliminates the need to decontaminate silt removed from the water using the currently available methods or devices.
