  • Patent number: 9399560
    Abstract: The preferred system utilizes two devices to recover larger diameter hoses and couplings. Each of the devices has a plurality of lifting frame arms having a motor disposed between the lifting frame arms. The motor is operatively connected to the rotational drive roller also connected between the lifting frame arms. A hinge or other attaching arrangement that connects the lifting frame arms to mounts allows for lowering the lifting frame arms into a first position and lifting the lifting frame arms into a second position higher the lower rollers. A hydraulic lift cylinder can be utilized to raise and lower the lifting frame arms when a hose coupling on the hose is encountered during the hose recovery process. The devices can be lined up in series and spaced a few feet apart. The devices can be mounted to a tractor, trailer, truck or other similar equipment. A cage can surround the devices on top of the tractor, trailer, truck or other similar equipment.

  • Publication number: 20120328372
    Abstract: A cable containing an optical fiber is used to transmit data between an underwater remotely operated vehicle (ROV) and a support vessel floating on the surface of the water. The ROV pulls the cable through the water and as the ROV dives away from the support vessel, the optical fiber is released from the support vessel. Excess tension in the cable can damage the optical fiber and the tension can be highest close to the ROV. To prevent potential damage to the optical fiber, the ROV can store a portion of the cable and release the cable if the detected tension approaches the maximum working load. When the tension drops to a lower safe level, the release mechanism can stop releasing the cable.

    Abstract: Apparatus for replacing underground pipe is described, including a resistance plate from which a pair of hydraulic cylinders extend perpendicularly in parallel with each other. The cylinders operate cyclically with a pulling bridge having a cable gripper to provide a sequence of pulling strokes to a cable pulling a mole. The mole pulls a replacement pipe behind it through the old pipe, which has been burst, slit, or otherwise expanded by the mole. The resistance plate is provided with a slot, and the cylinders are positions such as to allow the mode to be pulled substantially completely into the apparatus. A holding bridge is releasably mounted spanning the slot in the reaction plate to position a second cable gripper for holding the cable on return stroke of the pulling bridge. The holding bridge may be removed at the end of the pulling operation to accommodate the mole.
