  • Paravane system
    Patent number: 9880308
    Abstract: A paravane is described that includes a float member; a baffle coupled to the float member, the baffle comprising one or more fluid ports disposed at a flow-facing side of the baffle; and a fluid source coupled to the baffle by a conduit. The fluid is a drag-reducing fluid, which may be a gas. The fluid is flowed to the flow-facing side of the baffle to reduce towing force.
    Type: Grant
    Filed: October 21, 2015
    Date of Patent: January 30, 2018

  • Depth steerable seismic source array
    Patent number: 9395461
    Abstract: A steerable seismic energy source includes at least one float. The floatation device includes a device for changing buoyancy thereof. A frame is coupled to the at least one float. At least one seismic energy source is suspended from the frame. At least one steering device is coupled to the floatation device or the frame. The at least one steering device includes at least one control surface and a control surface actuator coupled to the control surface. The actuator is configured to rotate the control surface to generate hydrodynamic lift at least in a vertical direction.
