Abstract: A discharge control system for a reservoir having a pressure-communicating valve in a valve chamber with the inlet of the pressure-communicating valve connected the reservoir outlet aperture and the outlet of the pressure-communicating valve connected to a discharge aperture in the containment structure for the valve chamber. An auxiliary reservoir outlet aperture enables water to flow from the reservoir into the valve chamber, submerging the pressure-communicating valve. Water flows from the valve chamber through a valve chamber outlet aperture that is substantially the same as the auxiliary reservoir outlet aperture and is located at substantially the same height as the center of the reservoir outlet aperture. One or more supplemental auxiliary reservoir outlet apertures are located at incrementally greater heights in the containment wall for said reservoir to assure that water will enter and leave the valve chamber at the same rate under all conditions.

Abstract: This paper proposes an integrated approach to storm water management and storm water treatment. Today's requirements for capturing and treating the first-flush of storm water can be met with a new device that also controls peak flows over a wide range of storms and uses a net storage volume that is substantially lower than the storage computed by traditional reservoir routing methods. The extention basin debuts here as the most efficient method of reducing peak storm water flows—being far more effective than the retention or detention basins in common use today.

Abstract: A system for offloading LNG (liquified natural gas) from a tanker (26) in shallow waters, for regasing, or heating the offloaded LNG to produce gaseous hydrocarbons, or gas, for pressurizing the gas, and for flowing the gas to an onshore station (56), includes a structure that is fixed to the sea floor and projects above the sea surface and aids in mooring the tanker. In one system, the structure that is fixed to the sea floor is a largely cylindrical tower (12) with a mooring yoke (20) rotatably mounted on its upper end. A floating structure (14) such as a barge that weathervanes, has a bow end pivotally connected to a distal end of the yoke, so the barge is held close to the tower but can drift around the tower with changing winds, waves and currents. The tanker is moored to the barge so the barge and tanker form a combination that weathervanes as a combination.

Abstract: Stranded natural gas is sometimes liquefied and sent to other countries that can use the gas in a transport ship. Conventional receiving terminals use large cryogenic storage tanks to hold the liquefied natural gas (LNG) after it has been offloaded from the ship. The present invention eliminates the need for the conventional cryogenic storage tanks and instead uses uncompensated salt caverns to store the product. The present invention can use a special heat exchanger, referred to as a Bishop Process heat exchanger, to warm the LNG prior to storage in the salt caverns or the invention can use conventional vaporizing systems some of which may be reinforced and strengthened to accommodate higher operating pressures. In one embodiment, the LNG is pumped to higher pressures and converted to dense phase natural gas prior to being transferred into the heat exchanger and the uncompensated salt caverns.

Carbon dioxide may be stored within the portion.

Once an alarm is signaled, the product delivery system is shut down and an audio-visual alarm is activated in close proximity to operating personnel. An onsite service call by qualified personnel is required to return the product handling system back into service. A qualified service technician connects to a communication port on the system control module to evaluate the cause of the failure. The system utilizes vacuum pressure to monitor for containment breaches.

Abstract: A fluid containment basin having ridges located in the bottom of the basin and furrows adjacent to the ridges to facilitate maintenance of the basin using the naturally occurring forces of gravity, wave action and fluid currents. The ridges can be formed from material taken from the furrows into shapes that facilitate wave action against the sides of the ridges. While the fluid level is above the ridges, sediment settles on the ridges and furrows, reducing the permeability of the ridges and furrows and, therefore, the drainage from the basin. Wave action against the sides of the ridges as the fluid level is lowered washes the sediments off the ridges into the furrows, thereby restoring the permeability of the ridges. The wave action can be wind generated or induced by a wave mechanism. The furrows can be allowed to become impermeable or be lined to prevent contaminates from migrating.

Abstract: A drainage system for delivering fluid from a source of fluid for absorption into the ground, comprises a trench, a pair of perforated drainage conduits extending longitudinally in said trench and laterally spaced from each other to define an open chamber therebetween. The conduits are connected at one end to the source for receiving fluid from the source and delivering fluid to the chamber. A longitudinally extending cover overlies said conduits and prevents soil from falling into the chamber. The cover includes side portions which engage the conduits and a center portion connected to the side portions and maintains the conduits in laterally spaced relationship. The cover also includes reinforcing arches extending between the side portions and the center portion to resist downward deflection of the cover under the weight of the top soil. Vent holes in the cover permit the system to breathe.

Abstract: Grouting equipment and methods suitable for use in underground water wells, which accomplish their goals by better centering the grouting equipment within a bore hole, even in curved bore holes, in an manner that prevents leakage of the grout into the well. Improved grouting is achieved by using corrugated, bendable incasings and expandable tubes which create a seal between the incasing and the well wall for the grout, and which prevent both contaminated surface water and grout from contaminating the groundwater. The disclosed techniques are implementable in such a manner that grouting does not necessarily need to precede the location of a groundwater nappe.
