Abstract: The invention discloses an integrated detection method of electromagnetic searching, locating and tracking for subsea cables. After being launched into water, the cable-tracking AUV carries out primary Z-shaped reciprocating sailing to search the electromagnetic signal of the target subsea cable, when the electromagnetic signal reaches a preset threshold value, the AUV executes the cable-tracking detection. In the tracking process, if the target electromagnetic signal intensity is lower than the preset threshold, it is determined that subsea cable tracking is lost. At this time, the secondary Z-shaped cable-researching route planning and tracking are performed based on the lost point. In the process that the AUV autonomously tracks and detects the subsea cable, relative locating between AUV and subsea cable is performed based on the electromagnetic signal radiated by the subsea cable, and autonomous tracking control under the guidance of the electromagnetic locating signal is performed.

Abstract: A system has a submarine vessel and a submarine docking port. The docking port is arranged for transfer of electrical energy to the submarine vessel when the submarine vessel is docked. The submarine vessel has a submarine navigation system. The docking port has a primary coil for emitting a magnetic field. The submarine vessel has a secondary coil. The submarine vessel has means for measuring a strength of the magnetic field received by the secondary coil. The submarine vessel has a positioning electronics that guides the submarine vessel in a horizontal plane to maximize the measured local magnetic field. The positioning electronics guides the submarine vessel in the vertical direction when the measured magnetic field is at a local maximum and the magnetic field increases when the submarine vessel descends towards the primary coil. Also, a method is for docking a submarine vessel on a submarine docking port.

Abstract: A submersible node and a method and system for using the node to acquire data, including seismic data is disclosed. The node incorporates a buoyancy system to provide propulsion for the node between respective landed locations by varying the buoyancy between positive and negative. A first acoustic positioning system is used to facilitate positioning of a node when landing and a second acoustic positioning system is used to facilitate a node transiting between respective target landed locations.

Abstract: Autonomous underwater vehicles and systems are provided with fast stabilization and fine attitude control with a constant and high rotational speed flying wheel to rotate the vehicle's body with respect to its core and optionally a combination of reaction masses used in three perpendicular axes. The gimbal and the reaction mass inertial systems are used for fast response to any angular or linear disturbance coming from the ocean current or waves. When equipped for optical communications, the vehicle has an optical receiver and transmitter and controller that provides three levels of attitude stabilization: gimbal and the reaction mass inertial systems; isolated movable platform and fine optical beam steering for targeting the laser beam from the transmitter. The ability to maintain precise positioning allows multiple vehicles to be optically linked.

Abstract: Methods and apparatus for inspecting an underwater vehicle. In embodiments, a system receives a SAR image for at least a portion of an exterior surface of an underwater vehicle and performs CCD processing to compare a baseline SAS image for the underwater vehicle with the received SAR image of the underwater vehicle to generate a CCD output corresponding to a measure of similarity of the baseline SAS image and the received SAS image. The system determines whether there was tampering of the underwater vehicle based on the measure of similarity.

Abstract: A technique facilitates detection of gaseous emissions in a marine environment via a vessel or vessels traversing a region of the marine environment. Environmental data is collected via a detection system on each vessel and communicated to a processing system. The processing system processes various environmental data such as location data, emission detection data, wind data, and/or other data to determine an emissions result. This emissions result is output in a form to facilitate decision-making with respect to potential corrective actions to reduce the gaseous emissions.
