Abstract: An accessory is disclosed for a subsea pipeline such as an in-line tee having a rigid pipe support frame defining a pipe course and at least one carriage arranged to support a pipe or a fitting attached to a pipe. The carriage is movable with respect to the frame in a direction generally parallel to the pipe course. The carriage is attached to the frame via at least one angularly movable connection that allows a pipe or fitting supported by the carriage to tilt locally with respect to the frame as the pipe bends during laying. Pipe stiffness is therefore independent from the stiffness of the accessory. The stiffened section of the pipe is limited to a short length of the carriage. This is compatible with the small bending radius of the pipe on a stinger.

Abstract: A flow control system includes a movable riser with multiple flow rate restrictors within a stationary riser that is interfaced to a drainage system. The movable riser is buoyed by float(s) attached to the movable riser. As the fluid level around the flow control system changes, the movable riser tracks the changes, thereby raising and lowering the flow rate restrictors. Since the flow rate restrictors have differing areas in the horizontal plane, an interstitial opening between the outer edge of each flow rate restrictor and the inner perimeter of the stationary riser differs. The flow rate is constant and proportional to the depth of the fluid over the interstitial opening with the least area. The flow rate remains constant until that flow rate restrictor creating the smallest interstitial opening lifts above the upper edge of the stationary riser at which time, the next flow rate restrictor determines the flow rate.

Abstract: An application for a flow control system includes a movable riser in fluid communication and slideably engaged with a stationary riser, the stationary riser being in fluid communication with a drainage system. The movable riser is made buoyant by one or more attached floats such that, when the liquid level around the flow control system increases to a pre-determined level, the movable riser lifts due to the buoyancy of the float(s), thereby maintaining the pre-determined displacement as the water level continues to rise, yielding either a constant flow rate or a variable, predictable flow rate through the drainage system.

Abstract: The slag-only Vertical Flow Pond, which we have developed, is a passive treatment component capable of removing large concentrations of metals, especially manganese, from water to extremely low concentrations while neutralizing acidity and producing alkalinity. An improvement to this design is the Hybrid Flow Pond (HFP), which is a passive treatment system component that consists of an open, pond-like structure utilizing a horizontal operational flow path (or a vertical flow path if desired) with a vertical flush flow path. By creating flushing flow paths generally perpendicular to operational flow paths, the development of preferential flow paths that encourage short circuiting can be prevented. Additional head can be generated prior to flushing by adjusting the water level in the pond. Although any treatment media can be used with this system, the use of basic steel slag is particularly useful in the removal of metals, especially manganese from aqueous solutions.
