| 181 | AUTONOMOUS UNDERWATER VEHICLE AND METHOD FOR COUPLING TO OCEAN BOTTOM DURING MARINE SEISMIC SURVEY | US15179619 | 2016-06-10 | US20160280345A1 | 2016-09-29 | Thierry Brizard |
| An autonomous underwater vehicle (AUV) is configured to record seismic signals during a marine seismic survey. The AUV includes a body having a base (B) and first and second sides (A, C), the body having a head part and a tail part; a propulsion system for guiding the AUV to a final target on the ocean bottom; a seismic sensor configured to record seismic signals; and an anchoring system configured to rock or twist the base in a given sequence so that the base (B) penetrates into the ocean bottom. | ||||||
| 182 | Fluid-Based Buoyancy Compensation | US15135848 | 2016-04-22 | US20160229502A1 | 2016-08-11 | Bradley C. Edwards |
| Systems and methods for buoyancy compensation are provided. Both active and passive buoyancy compensation can be provided using a compressible mixture made of a liquid along with a hydrophopic material such as a powder, electrospun fiber, or foam. The compressible fluid compresses as pressure is applied or expands as pressure is released thereby substantially maintaining an overall neutral buoyancy for a vessel. This allows the vessel to ascend and descend to water depths with minimal active buoyancy change. As a result, the energy usage and the reliance on higher pressure air and oils can be minimized. | ||||||

| 190 | Marine Seismic Surveying with Towed Components Below Water's Surface | US14339736 | 2014-07-24 | US20150101420A1 | 2015-04-16 | Curt Schneider; Timothy A. Dudley |
| A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source (e.g., air gun array) of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and the source. A floatation device supports the source and tows below the water's surface to avoid ice floes or other issues encountered at the water's surface. Seismic streamers have head floats supporting the streamers. Each of the floats has adjustable buoyancy preconfigured to counterbalance the weight in water of the towed component that the float supports. Acoustic signals from a transceiver at the vessel find locations of the towed components. A towed fish at a lower level than the towed components also uses acoustic signals with a transceiver to further refine the locations of the towed components. | ||||||

| A submersible apparatus (10) which can be fully submerged in a liquid medium, includes: a sealed hollow body (12) having a longitudinal main axis (A); at least one driving member (14, 36, 52) for moving the apparatus (10) horizontally and/or vertically, which can co-operate with the medium in which the apparatus (10) is submerged and which can move in relation to the hollow body (12) through an opening (22, 44, 56) provided in the wall of the body (12); and elements (18, 40, 64) for actuating the driving member (14, 36, 52), which are disposed inside the hollow body (12).

| 197 | Neutrally buoyant submerged system using lesser density ballast fluid | US12473485 | 2009-05-28 | US07987805B1 | 2011-08-02 | James Buescher; Peter Sullivan; Aaron Bratten |
| The invention provides a means by which the attitude or orientation of a submerged object can be changed or altered using a fixed quantity of transferable ballast fluid which has a density less than that of the surrounding fluid in which the object is submerged. In one embodiment, the process utilizes a static negatively buoyant material (which could be a lead weight) to offset the net negative buoyancy of the transferable ballast fluid. In this way, the total overall buoyancy of the system does not change, but by transferring ballast fluid into expandable reservoirs which are physically separated from the static negatively buoyant material, the separation between the center of buoyancy and the center of mass of the object can be changed, and thus the attitude or orientation of the object, if it is unrestrained, may be changed. | ||||||
