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. The AUVs are configured to acoustically communicate with the underwater vehicle or a second surface vessel for deployment and retrieval operations. The underwater vehicle and/or second surface vessel is configured to instruct the AUVs to leave the subsea station or underwater vehicle and to travel to their intended seabed destination. The underwater vehicle and/or second surface vessel is also configured to selectively instruct the AUVs to leave the seabed and return to a seabed location and/or a subsea station for retrieval.Type: GrantFiled: September 12, 2018Date of Patent: July 13, 2021Assignee: Seabed Geosolutions B.V.Inventors: Arne Henning Rokkan, Geir Valsvik, Bjarne Isfeldt, Jean-Baptiste Danre

Publication number: 20190256181Abstract: Apparatuses, systems, and methods for the deployment of a plurality of seismic autonomous underwater vehicles (AUVs) on or near the seabed. In one embodiment, the AUV comprises a buoyant body coupled to a pressure vessel that contains substantially all of the AUV's electronic components. The pressure vessel may comprise a plurality of composite components coupled together by a metallic ring to provide a substantially cylindrical shape to the pressure vessel. The AUV body provides lift to the AUV during lateral movement and compensates for an overall negative buoyancy of the AUV. The AUV may include a plurality of thrusters for propulsion. A vertical thruster may be used to create an upwards attack angle during takeoff and to maintain depth and orientation during flight. During normal flight operations, the AUV is configured to travel horizontally and vertically in a body of water by using only the horizontal thrusters.Type: ApplicationFiled: May 7, 2019Publication date: August 22, 2019Applicant: Seabed Geosolutions B.V.Inventors: Geir Valsvik, Arne Henning Rokkan, Johan Fredrik Næs, Matthew E. Silvia, Christopher J. von Alt
