摘要： Systems and methods for deployment and retrieval of ocean bottom seismic receivers. In some embodiments, the system includes a carrier containing receivers. The carrier can include a frame having a mounted structure (e.g., a movable carousel, movable conveyor, fixed parallel rails, or a barrel) for seating and releasing the receivers (e.g., axially stacked). The structure can facilitate delivering receivers to a discharge port on the frame. The system can include a discharge mechanism for removing receivers from the carrier. In some embodiments, the method includes loading a carrier with receivers, transporting the carrier from a surface vessel to a position adjacent the seabed, and using an ROV to remove receivers from the carrier and place the receivers on the seabed. In some embodiments, an ROV adjacent the seabed engages a deployment line that guides receivers from the vessel down to the ROV for “on-time” delivery and placement on the seabed.

摘要： A buoy, comprising a body, an inflatable bladder, a bladder cover, a pressure vessel, a variable-volume, gas-filled chamber, a controller, a compressor, and a ballast. The bladder cover surrounds the inflatable bladder. When the inflatable bladder is deflated, the bladder cover is configured to compress the inflatable bladder so as to conform to an exterior contour of the body. The variable-volume, gas-filled chamber provides passive, variable buoyancy to the buoy. The controller is configured to control a transfer of compressible gas between the inflatable bladder and the first pressure vessel. The compressor is configured to remove gas from the inflatable bladder, compress the removed gas, and introduce the compressed gas to the first pressure vessel for storage. The ballast maintains a substantially vertical orientation of the buoy when the buoy is in water.

摘要： A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.

摘要： A floating connector of an offshore energy device and a method for connecting the floating connector is provided. The floating connector includes a buoy having a tube, a bay, a joint box, and at least one cable for connecting to the offshore energy device. The buoy provides buoyancy to the floating connector and includes the tube and bay. The bay houses the joint box, which electrically couples the at least one cable to each other and to a switchgear of the offshore energy device.

摘要： The invention relates to an automatic retractable float for use with a crab net including a body which floats in water and an automatic retraction and extension mechanism for automatically extending and retracting line from the body. In use the line is attached to the crab net, the crab net deployed and the body floats when in water towards the surface of the water. The automatic extension and retraction mechanism causes the line to be extended and retracted between the body on the surface of the water and the crab net, substantially keeping the line taut to help prevent tangling. The invention also relates to a method of use.

摘要： A buoy and mooring system provides a robust buoy protective of markings thereon, easily retrieved for inspection and service, weighted and levered for maintaining self-righting, vertical orientation and anchored with a non-corroding system of connectors and links running from surface to sea floor. A mid-line float resists entanglement, and can be installed or uninstalled by operation of various “worm grip” mechanisms. A slack line region accommodates changing tides. An upright tube, weighted at a lower end and flanged at an upper end thereof, secures a buoy in place but pulls up through the buoy for easy retrieval by boat crews. Embedding an anchor is by hydraulic water jet drilling. From a thimble in the anchor to a thimble in the upright at the buoy, no intervening metal components are needed in the load path. Markings are durably and protectively embedded in recesses below the buoy's outer surface.

摘要： A computing apparatus that is integrated within a flotation module, the system obtaining the energy required to power its computing operations from waves that travel across the surface of a body of water on which the flotation module sets. Additionally, the self-powered computing apparatus employs novel designs to utilize its close proximity to the body of water and/or to strong ocean winds to significantly lower the cost and complexity of cooling their computing circuits.
