Liquefied natural gas floating storage regasification unit

An offshore liquefied natural gas floating storage regasification unit that may receive, store, and process liquefied natural gas from carriers. A floating storage regasification unit may include transfer equipment to offload liquefied natural gas from a carrier, a first mooring system to provide for mooring of a floating storage regasification unit at a location in a body of water, a second mooring system to provide for mooring a carrier to the floating storage regasification unit, and combinations thereof. A portion of the floating storage regasification unit may be composed of a double-hull containment structure.

Apparatus and method for flowing compressed fluids into and out of containment

Methods for loading a compressed fluid, such as natural gas, into and discharging the compressed fluid out of containment are provided. The compressed fluid is injected into a bottom portion of a container system for storage and/or transport until a target pressure is reached after which gas is withdrawn from an upper portion of the container system at a rate to maintain the target pressure while the compressed fluid is injected in the bottom portion. The compressed fluid is cooled through an expansion valve and by refrigerated chillers or by injecting a cold liquid of the same chemical composition as the compressed fluid, such as liquid natural gas, into the compressed fluid prior to injection into the container system. Withdrawal or discharge from the container system to a receiving facility begins with blow down from the bottom portion of the container system without a displacement fluid and continues until pressure falls below an acceptable differential pressure. The discharge stream is passed through a separator and a light gas from the separator is pressurized and injected into an upper portion of the container system to drive the compressed fluid out the bottom. The light gas is pressurized using either a compressor or a heated tank system, where two vessels operate in parallel, trapping and heating the light gas and then discharging to the container system from one while filling the other and alternating the operation between the two.

Fluid storage and dispensing system featuring externally adjustable regulator assembly for high flow dispensing

A fluid storage and dispensing system including a fluid storage and dispensing vessel enclosing an interior volume for holding a fluid. The vessel includes a fluid discharge port for discharging fluid from the vessel. A pressure regulating element in the interior volume of the fluid storage and dispensing vessel is arranged to flow fluid therethrough to the fluid discharge port at a set pressure for dispensing thereof. A controller external of the fluid storage and dispensing vessel is arranged to transmit a control input into the vessel to cause the pressure regulating element to change the set pressure of the fluid flowed from the pressure regulating element to the fluid discharge port. By such arrangement, the respective storage and dispensing operations can have differing regulator set point pressures, as for example a subatmospheric pressure set point for storage and a super atmospheric pressure set point for dispensing.
