Patent number: 11059552Abstract: Apparatuses, systems, and methods for the deployment of a plurality of autonomous underwater seismic vehicles (AUVs) on or near the seabed based on acoustic communications with an underwater vehicle, such as a remotely operated vehicle. In an embodiment, the underwater vehicle is lowered from a surface vessel along with a subsea station with a plurality of AUVs.

Publication number: 20190094402Abstract: Disclosed is a method for determining skew measurements for clock errors in an autonomous seismic node. A parabolic fit may be used to estimate the clock drift of an ocean bottom seismic node during node deployment. A temperature and/or frequency trend and a real-time temperature measurement may be used to compute a temperature corrected parabolic trend. The temperature and/or frequency trend may be measured in a laboratory on a node by node basis or it may be a single trend that is suitable for all nodes. The method may include measuring clock skew prior to node deployment and after node recovery, correcting the pre and post deployment skew measurements based on a temperature and/or frequency trend and/or to a constant reference temperature, and/or computing a parabolic trend of the skew measurements of the clock based on the temperature corrected pre and post deployment skew measurements.Type: ApplicationFiled: September 25, 2018Publication date: March 28, 2019Applicant: Seabed Geosolutions B.V.Inventors: Timothy John Bunting, Bjarne Isfeldt
