Une telle plateforme peur constituer un drone apte à évoluer tant dans les airs que dans les eaux.
Abstract:
An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey. The AUV(400) includes a body (402) extending along an axis X and having a head portion (404), a middle portion (406), and a tail portion (408), wherein the middle portion (406) is sandwiched between the head portion (404) and the tail portion (408) along the X axis;a cross-section of the middle portion (406), substantially perpendicular on the X axis, having a triangular-like shape;the head portion (404) including a base portion (404b) having the triangular-like shape and configured to match the middle portion (406); the head portion (404) having a tip (404c) that, when projected along the X axis on the base portion (404b), substantially coincides with a centroid of the base portion (404b) having the triangular-like shape; anda seismic payload (704) located within the body (402) and configured to record seismic signals.
Abstract:
An integrated power distribution system utilizes a subsea power distribution hub that receives high voltage electricity through an umbilical from a host surface facility. The subsea power distribution hub steps down the high voltage electricity and distributes the appropriate electrical power supply to multiple components of a subsea production system (e.g., in-well pumps, subsea booster pumps, subsea processing units, subsea valves, and subsea sensors) via jumpers. The integrated subsea power distribution system can be utilize to supply electrical power to all of the required process components of the subsea production system from the in-well completion to the surface host facility.

Abstract:
The method for lowering an object (1) to an underwater installation site (2), wherein a submersible remotely operated vehicle (ROV) (20) having at least one thruster for providing lateral thrust is interconnectable to an object (1), entails providing a vessel (10), having a winch (13) and suspension cable (14); interconnecting and lowering the object (1) and ROV (20) towards the underwater installation site using a suspension cable (14), providing at least one anchor (30) near the installation site; interconnecting each anchor (20) and ROV (20) with a positioning wire (32), while the ROV and object are suspended in the holding position; tensioning and adjusting the length of each positioning wire (32) such that the interconnected ROV and object are positioned with respect to the installation site; and further lowering interconnected object (1) and ROV (20), which are positioned by at least one positioning wire (32) onto the installation site while keeping the interconnected object and ROV suspended from the suspension cable (14).
Abstract:
An ROV comprising a topside (12), a fish (10) and an umbilical cable (14) for connecting the topside (12) and the fish (10) together. The fish (10) is adapted to be powered by an onboard battery (52) inductively coupled to the fish (10). The cable (14) is of a fine diameter to reduce drag through the water. RF transmissions carry control and return signals to and from the fish (10) and topside (12). The fish (10) has two cameras. The front facing camera is located behind a dual layer flooded dome (34). A pan and tilt mechanism is fitted to one of the cameras and uses a pivotable gimbal frame (233) driven by a lead nut (243) moving along an arcuate bolt (241).
Abstract:
An apparatus and methods for deploying, recovering, and servicing an (autonomous underwater vehicle) AUV (60) are disclosed. The apparatus includes a linelatch system (10) that is made up of a tether management system (12) connected to a flying latch vehicle (20) by a tether (40). The linelatch system can be connected to a surface vessel (50) by an umbilical (45) on one end and to an AUV on the other end. In addition to providing a mechanical connection, between the AUV and a surface vessel, the linelatch system can also carry power and data between the surface vessel (i.e., through the umbilical) and the AUV.
Abstract:
A submersible vehicle (10) is provided which is able to achieve six of freedom utilizing a combination of only two thrusters with no external control planes. Each of the two thrusters can include a plurality of ducts (28) which can be selectively opened or closed, to varying degrees, to achieve six degrees of freedom for both control and propulsion.
