Abstract: A scrubbing solution for removing contaminants, including particularly hydrogen sulfide, from a fluid. The scrubbing solution includes at least one scrubbing reagent which has a primary or secondary amine and an acid, which may be phosphoric acid. The fluid being scrubbed is passed through the scrubbing solution. The contaminants react with the scrubbing reagent securing them in the scrubbing solution. The fluid being scrubbed and the scrubbing solution are then separated. The scrubbing solution is heated and, if the scrubbing solution is under pressure, the pressure is reduced. The acid facilitates thorough removal of the contaminants, and especially the hydrogen sulfide, from the scrubbing solution. The scrubbing solution is then ready for reuse. Because the scrubbing solution is rendered substantially free of hydrogen sulfides, it can absorb other sulfide contaminants that might not otherwise be absorbed.

Abstract: Systems and methods for coupling subsea tubular members together are provided. An apparatus may be used to properly orient and/or provide communication between a first subsea tubular member that is being landed on a second subsea tubular member. An apparatus for coupling subsea tubular members may include an alignment sub and a corresponding alignment member. The alignment sub includes: a generally cylindrical body having one or more fluid, electric, or fiber optic lines extending therethrough, one or more couplings coupled to at least one end of the alignment sub, and an orientation profile disposed on a surface of the alignment sub. The alignment member has a profile designed to interface with the orientation profile of the alignment sub. One of the alignment sub and the alignment member remains stationary while the other rotates relative to the stationary structure.

Abstract: Systems and methods for landing a tubing hanger in a wellhead and then orienting a tree (or spool, or flowline connection body) relative to the tubing hanger while landing the tree on the wellhead are provided. This alignment is accomplished without the use of either a tubing spool or a BOP stack with an orientation pin. The tubing hanger alignment devices may be used to orientate the tree as the tree is landed so that the couplings and stabs between the tree and the tubing hanger line up with each other just at the moment of landing.

Abstract: A reinforcing system for a vessel that can contain water is described. The system includes a shell for containing water, the shell having one or more jets extending therethrough from an inside of the shell to an outside of the shell, and a structural support layer on an underside of the shell. The structural support layer can include: an inner layer of rigidizer applied to the underside of the shell, a central low density core, and an outer layer of rigidizer applied to the central low-density core. The structural support layer can extend from a bottom side of the underside of the shell, across at least one sidewall of the underside of the shell, and form at least one rib along the sidewall of the underside of the shell.

Abstract: A system and method for reinforcing a spa shell includes a structural support layer on an underside of the spa shell. The structural support layer may include an inner layer of rigidizer, a central foam layer, and an outer layer of rigidizer. The structural support layer may extend from a bottom side of the underside of the spa shell, across at least one sidewall of the underside of the spa shell to a lip of the spa shell, the structural support layer forming at least one rib along the sidewall of the underside of the spa shell.

Abstract: A system and method for providing a hammock for a user to rest thereon in the water of the spa. The hammock may include a proximal end with head support portion and one or more attachment means for connection to an anchor on the spa shell, and a distal end with one or more attachment means for connection to an anchor on the spa shell. One or more lateral coupling members may couple the hammock to the lateral sides of the spa, and one or more longitudinal coupling members may couple the hammock to a front side and/or back side of the spa. The longitudinal and lateral coupling members may support the hammock in the water to give the user a unique flotation experience.

Abstract: A system for supporting a spa shell may include a structural support paddle. The paddle may include a base portion and a paddle portion, connected to each other through an articulating joint such as a ball-and-socket. The top side of the paddle portion may include one or more pieces of cushioning material, such as EPF foam. The structural paddle assembly may be placed between the base of the spa and the spa shell. Typically, 5 or more paddle assemblies are placed in a spa for support, such as in the lowest areas of the spa shell and/or concavities, or convexities, of the spa shell. Compared to typical large blocks of foam used to support a spa shell from beneath, the structural support paddles provided increased room below the spa shell for ease of maintenance and installation, and more directly controlled support.

Abstract: A system and method for providing an exercise bar for a user to use for rowing or other exercises in the water of the spa or adjacent to the spa. The exercise bar may comprise a central hub, and two sides, each with a first inner tube attached to opposing side of the central hub and a an outer tube in telescoping connection with the inner tube, and a handgrip in connection with the first outer tube. A connector may be mounted to the central hub, the connector to enable the exercise bar to be connected to one or more resistance cables. The exercise bar may be adjustable from a first, shorter length for use with exercises in which a user's hands are positioned closer together and a second, longer length for use with exercises in which a user's hands are positioned father apart.

Abstract: A water recreational apparatus has a water basin, a pump, a filter and a filter opening. The water basin has side walls and a bottom wall. The water recreational apparatus further includes one or more downwardly directed sweep jets disposed within the water basin proximate to the side walls. The sweep jets are disposed above the bottom wall by a distance of less than 10 inches. The sweep jets are in fluid tight communication with the discharge side of the pump so that water can be pumped through the sweep jets to roil water at the bottom of the water basin. By roiling the water at the bottom of the water basin, debris which tends to collect along the bottom of the water basin is moved upward within the water basin to where it can be removed via the filter opening and the filter.
