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 that records seismic data. Additionally, the node may include supplementary components such as hydrophones, geophones, accelerometers, and a timing device to synchronize data recording. An energy source is also integrated to power the sensor and memory, ensuring continuous operation during seismic surveys.
Furthermore, the patent outlines an ocean bottom seismic survey apparatus comprising multiple nodes connected by a cable. Each node retains the modular housing and memory, along with the multi-axis acceleration sensor. The cable serves dual functions: it can operate in a passive mode without transmitting signals or power, or in an active mode where it facilitates communication and energy transfer between nodes. A floating hub is proposed to enhance connectivity, equipped with a master clock and energy source, which transmits signals and power to the nodes. The design also includes termination devices at both ends of the cable, ensuring effective operation in underwater environments. This patent represents a significant advancement in ocean bottom seismic technology, potentially improving the efficiency and accuracy of seismic surveys.
