Our multi-disciplinary team of experienced industry professionals has developed a suite of hardware components and software modules for efficient ocean bottom node (OBN) seismic operations. Our products offer a step change in the safe and efficient operation of OBN surveys and they are now available to the market individually or as part of the complete and fully integrated Venator system.

Ocean Bottom Nodes

Our nodes use the latest components and technologies available giving the users the best data quality and functionalities. All nodes have the same well proven electronics and firmware. Built-in transponder for positioning and real time node status is optional.
