Autonomous Nodal Marine Seismic Technology

By eliminating the traditional sources of technical downtime in Ocean Bottom Cable (OBC) system, autonomous seismic nodes can deliver higher productivity and hence more cost effective ocean bottom data acquisition. HSE exposure and risk is reduced through the removal of a recording platform - either a recorder vessel or 2 ton recording buoys - in combination with the automation of the node handling system on the back deck of the vessel. Data quality is superior to that acquired with digital accelerometers since the noise floor of the omni-directional geophones used is substantially lower, especially at low frequencies, than that of the digital sensors commonly used in present day OBC systems.
