Abstract: The invention relates to the field of special purpose robotic systems to conduct external functions such as cleaning, monitoring and inspection of structures such as tubular assets in a splash zone. The splash zone is defined as the section of a marine structure that is periodically in and out of water due to the action of waves or tides, usually falling within (+)10m to (?)20m water depth. In embodiments, splash zone inspection robot system 1 comprises station 300, submersible saddle 350, submersible robot 400, and subsea robot controller 308. A predetermined set of controllable clamps selectively secure submersible robot 400 to submersible saddle 350 or structure 2 and allow incremental traversal along submersible saddle 350 or structure 2.

Abstract: Regeneration of a fluid medium can be accomplished using a continuously regenerable scrubber, which, in its various embodiments, combines valve functions and sorbent material, such as amine beds, into one component, dramatically reducing size and mass of scrubber. Sorbent material beds rotate continuously past breathing gas vent loop ports for scrubbing CO2/H2O and then past vacuum ports for regenerating the sorbent material. Typically, a first fluid output is connected to a lower header fluid output and a second, sweeping fluid source connected to a lower header fluid input. A motor spins the substantially circular bed assembly at a predetermined speed which allows adsorption or absorption as well as desorption of materials flowing through the sorbent material.

Abstract: Electro oxidation membrane evaporator 1 comprises sweep air handler 60; fluid tank 20 defining a fluid container; fluid contactor/separator 30; oxidation cell 40; and scrubber 80. Electro oxidation membrane evaporator 1 may allow higher percent water recovery from wastewater prior to delivering brine to a brine water recovery system and can allow O2 from air such as cabin air to continuously diffuse into the wastewater as O2 is consumed to generate oxidants, helping to eliminate the low oxidant environment at the end of the cycle that causes pH to remain high, and low pH prevents precipitates from forming for longer so more water can be evaporated from the wastewater.

Abstract: In embodiments, motion may be arrested and/or dampened using a motion arresting and dampening device comprising a lifting spreader bar, one or more bar mounted winches, deployment wire, a restorative inflation device, restraining wires and winches, hoses and controller, mechanical connection release system circuitry. Multiple restraints from winches mounted strategically on a vessel crane's boom may be applied to the spreader bar to restrain the bar during the lifting operation. The forces induced into the lifted object by the movement of the crane as it deploys the object into installation position are attenuated by the physical restrain of the adjustable wires. These adjustable wires may also be used to provide rotation of the object during final alignment of the object during installation.
