Abstract: A control system provides steering control commands to a steering actuator of a steering device on a piece of towed marine equipment. A memory in the control system stores setpoint data including positional values for a desired position of the piece of towed marine equipment. A control module is configured to receive the setpoint data, receive process data representing a calculated actual position of the piece of towed marine equipment; and calculate a control command for the steering actuator of the steering device based upon the setpoint data and the process data. A disturbance adjustment calculation module is configured to combine a disturbance value based upon a measured disturbance with a value of the process data and output a disturbance adjustment value. A correction calculator module adds the disturbance adjustment value to the control command to create an adjusted control command for transmission to the steering actuator.

Abstract: An example system for deploying seismic sensor stations includes a cable storage device configured to deploy a rope, and a plurality of seismic sensor stations each having a respective coupling mechanism. The respective coupling mechanism of a seismic sensor station of the plurality of seismic sensor stations is configurable in a first position such that the rope is free to deploy through or by the seismic sensor station, and is configurable in a second position such that the rope is gripped to attach the seismic sensor station to the rope for deployment. The example system further includes a deployment control system configured to selectively cause the respective coupling mechanism of each of the plurality of seismic sensor stations to grip the rope.

Abstract: A marine seismic sensor system includes a seismic node having at least one seismic sensor. The sensor is configured for sampling seismic energy when towed through a water column on a rope. The coupling can be adapted to modulate transmission of acceleration from the rope to the seismic node.
