Multi-axis acceleration sensor for ocean bottom seismic nodes
The granted patent US12019197B2 introduces an innovative ocean bottom seismic node designed for enhanced seismic data collection. The core of this invention is a modular housing that contains a multi-axis, single-mass acceleration sensor capable of measuring both translational and rotational motion across three axes. This sensor features a central mass suspended within a frame and is connected to a memory unit for recording seismic data. Additionally, the node can be equipped with various components such as hydrophones, geophones, or accelerometers, and includes a timing device for generating timing signals essential for accurate data recording. An energy source is also integrated to power the sensor and memory, ensuring continuous operation during seismic surveys.
The patent further details an ocean bottom seismic survey apparatus that comprises multiple nodes connected by a cable. Each node retains the modular housing, memory, and multi-axis acceleration sensor. The cable serves dual functions, capable of transmitting power and signals in both passive and active configurations. It can carry various signals, including clock, data, and control signals. A floating or suspended hub is included in the design, which facilitates communication and power distribution between the nodes and the hub. The hub is equipped with a master clock and an energy source, allowing it to transmit clock signals and power to the nodes, which may also contain batteries for additional energy storage. The apparatus is completed with head and tail termination devices that are interconnected by seawater, enhancing the overall functionality and efficiency of the seismic survey system.
