A high pressure swivel system provides fluid communication on a turret-moored vessel between a swivel core member being in fixed rotational alignment with a seabed mooring system and a swivel revolving member being in fixed rotational alignment with the hull of the vessel. The revolving member has upper and lower radially extending surfaces. On each of the radially extending surfaces are a series of radially spaced apart pressure seals. Hydraulic barrier fluid pressure is regulated in each of the volumes formed between the pressure seals. The pressures in the volumes are regulated such that a process fluid pressure higher than could be tolerated by any one individual pressure seal is safely accommodated by sharing the high process fluid pressure between or among two or more of the radially spaced apart pressure seals.

The present disclosure relates to methods, apparatuses, and systems for a compact, low-cost drift buoy for use in a variety of applications. An example includes a drift buoy including a body defining a payload cavity; a float; and a controller, where the controller is configured to cause the drift buoy to release a payload when one or more predetermined conditions are satisfied. According to some embodiments, the controller is configured to establish a location of the drift buoy. According to certain embodiments, the one or more predetermined conditions include a location condition, where in response to the location of the drift buoy being within a target location, the controller causes the drift buoy to release the payload from the payload cavity.

Proposed is an underwater drift tracking system based on a maritime positioning platform. The underwater drift tracking system may include a plurality of underwater drifting objects configured to transmit sound wave signals including their own water depth information by using sound wave communication while drifting underwater. The underwater drift tracking system may also include a maritime drift tracker configured to track real-time underwater locations of the underwater drifting objects by moving on the sea under its own power, receiving the transmitted sound wave signals from the plurality of underwater drifting objects, and calculating absolute location information of the plurality of underwater drifting objects using the received sound wave signals.

Methods and systems are provided for transient fluidic coupling via reversibly couplable conduits. In one example, a method includes directing a conduit assembly to a receiving port by releasing one or more fluid streams from the conduit assembly. The method may further include fluidly coupling an internal passage of the conduit assembly to the receiving port. The internal passage may extend from the conduit assembly and along a conduit between a pair of free-floating bodies, such as between a wave engine and a tanker ship, so as to exchange one or more fluids, such as an electrolysis reactant and an electrolysis product. The fluidic coupling may be reversible, in that the conduit assembly may be detached from the receiving port to sever the fluidic coupling. In certain examples, the detaching may be actuated by releasing one or more additional fluid streams from the conduit assembly.

The invention is an apparatus unit that adjusts the dispersion from a compartment to an aqueous solution in response to an independent variable such as an environmental factor, in order to optimize seeding, marking, warning or treatment. The compartment enables any selection of solids, liquids or gasses to be contained and mixed when ready for dispersion. A preferred embodiment is a solar powered pump, self-contained within a buoy over a shallow tidal pool, for the purpose of distributing seeds for marine vegetation under ideal conditions for propagation. The unit provides for sensing and measurement of the environment, then adapting the dispersion for optimum effect.
