  • Patent number: 11077920
    Abstract: A marine array having various embodiments of a modular foil system is disclosed. The modular foil system may be configured to generate lift when towed in a marine environment, and thus used to move, position, and/or depress instrument of the array. The modular foil system may include multiple groups of foil sections, each having an angle of attack that is adjustable relative to other groups of foil sections. For example, each group may be supported by a pair of through cables, and an actuator may adjust a tension in one or both of through cables, thereby alerting the angle of attack. The pair of through cables may converge toward one another at connection points adjacent opposing ends of a given group of foil sections of the modular system. The connection points thus establishing a modular framework to couple the given group to other groups of foils of the system.

  • Publication number: 20190377348
    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.

  • Patent number: 10408959
    Abstract: A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source (e.g., air gun array) of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and the source. A floatation device supports the source and tows below the water's surface to avoid ice floes or other issues encountered at the water's surface. Seismic streamers have head floats supporting the streamers. Each of the floats has adjustable buoyancy preconfigured to counterbalance the weight in water of the towed component that the float supports. Acoustic signals from a transceiver at the vessel find locations of the towed components. A towed fish at a lower level than the towed components also uses acoustic signals with a transceiver to further refine the locations of the towed components.

  • Patent number: 10379240
    Abstract: Methods and apparatuses are disclosed that assist in correlating subsequent geophysical surveys. In some embodiments, geophysical data may be generated including a first set of data from a monitor survey that is matched with a second set of data from a baseline survey. An attribute value may be generated for each datum in the first set of data and each attribute value generated may be stored with its corresponding datum. Then, the first set of data may be processed based on the stored attribute values. In some embodiments, the attribute values may be based upon the geometric closeness of sources and receivers in the baseline and monitor surveys.

  • Patent number: 10339478
    Abstract: A networked system shares operational information (tasks, positions, times, etc.) between dissimilar operators performing dissimilar operations in a same marine field. The shared information include associations (linkages and conflicts) that allows each operator to optimize its operations and complete tasks in a more efficient manner. As part of this system, a planning tool having a graphical user interface can be used to visualize plans at an operator (and nearby operators). Changes made to plans by one operator are shared with other operators via the system and illustrated in the interface at the other operators, thereby allowing the other operators to make their own respective operational changes in response.
