Abstract:
Disclosed is a pump tower disposed inside a liquefied gas storage tank so as to supply or discharge liquefied gas to/from the inside of the liquefied gas storage tank. The pump tower, according to one embodiment of the present invention, comprises: a discharge pipe used for discharging the liquefied gas in the liquefied gas storage tank; an emergency pipe equipped with an emergency pump at the lower end thereof; a charge pipe for supplying the liquefied gas into the liquefied gas storage tank; and a support, which is provided on the bottom of the liquefied gas storage tank, for enabling the vertical displacement of the pump tower and restricting the horizontal movement and rotation thereof. The support comprises: a lower body fixed to a hull side; an upper body fixed to a pump tower side; and a wedge member interposed between the lower body and the upper body.
Abstract:
Initially, a ship containing LNG sails to an existing offshore natural gas pipeline. Such pipelines are often found on offshore natural gas platforms. The ship containing LNG then connects to a gasification device, which may be located on the ship, the platform, or on another ship (e.g., a barge). This gasification device, in turn, connects to the pipeline and supplies the pipeline with natural gas. In this manner, natural gas can be supplied to an existing pipeline without involving a land-based gasification device.
Abstract:
Methods, apparatuses and systems directed to clathrate hydrate modular storage, applications and utilization processes. In one implementation, the present invention provides a method of creating scalable, easily deployable storage of natural gas and thermal energy by assembling an array of interconnecting, modular gas clathrate hydrate storage units.

Abstract:
A secondary containment cap apparatus for a turret of a hazardous fluid primary container having a primary container wall with a primary container turret opening having a turret opening perimeter wall, the secondary containment cap apparatus including a valve mounting plate extending over and covering the turret opening in sealing relation with the perimeter wall, the valve mounting plate having at least one valve port fitted with a fluid passing container valve; a containment cap including a cap wall with a concave cap interior and a cap abutment port, the cap abutment port having a cap abutment port rim, the containment cap being secured onto the valve mounting plate so that the container cap covers and encloses the fluid passing container valve, the cap abutment port rim being sealingly retained to the valve mounting plate; and a cap attachment structure securing the valve mounting plate to the perimeter wall.
Abstract:
A secondary containment cap apparatus is provided for securing to a primary container containing a hazardous fluid, the primary container having a primary container wall with a primary container hazardous fluid passing port and a primary container wall exterior surface, the secondary containment cap apparatus including a cap wall defining a concave cap interior and a cap abutment port, the cap abutment port having a cap port rim, the cap abutment port and cap port rim being configured to fit closely against and follow the primary container wall in sealing relation with the primary container wall exterior surface and thereby to enclose a region of the primary container wall exterior surface to provide secondary containment over the region of the primary container wall exterior surface; a mechanism for controlled release of the fluid through the cap wall; and a mechanism for securing the cap wall to the primary container so that the cap port rim sealingly abuts the primary container wall exterior surface, such as a weld or tensioned cables.
Abstract:
A tank for the transport or storage of liquified natural gas under pressure is of generally rectangular form and has its side, top and bottom walls each composed of a series of parallel lobes of part-spherical cross-section and of say, 3.0 to 4.0 meters chord distance, each tank end consisting of either a like series of lobes or a mosaic of domes. All the inter-lobe nodes of the top wall of the tank are united to the corresponding nodes of the tank bottom by vertical tie-plates; likewise all the corresponding inter-lobe nodes of the two side walls are united by transverse tie-plates which intersect the vertical tie-plates orthogonally, and thereby define with them a plurality of tunnels of square cross-section.The tie-plates extend longitudinally to unite the end walls of the tank and are welded to one another at all tie-plates inter-sections. The tank is supported on a series of parallel support ribs or frames that connect with the tank along the inter-lobe nodes of the tank bottom.
Abstract:
A ship having a hold containing a tank, for transporting a cryogenic liquefied gas, which is structurally free-standing and is spaced or separated from the ship hold walls, insulation secured to the ship hold walls and hold bottom, a ship hold cover extending over the tank top portion and joined to the ship, and a layer of loose fill insulation and a resilient blanket layer between the tank top portion and the ship hold cover.
Abstract:
A STRUCTUREAL LIGHT-WEIGHT PANEL OF HIGH STRENGTH, HAVING THERMAL INSULATION PROPERTIES THAT RENDER THE PANEL PARTICULARLY SUITABLE FOR CRYOGENIC AND ELEVATED TEMPERATURE APPLICATIONS. THE PANEL IS CONSTITUTED BY A COMPOSITE CORE BONDED TO A CARRIER MEMBRANE OR LAMINATED TO FACING SKINS, THE CORE INCLUDING AT LEAST ONE LAYER FORMED BY A SERIES OF BALSA BEAMS IN SPACED PARALLEL RELATION, THE SPACING BETWEEN THE BEAMS BEING FILLED WITH SLABS OF FOAM PLASTIC MATERIAL WHOSE K-FACTOR IS SIMILAR TO THAT OF BALSA, WHEREBY THE OVERALL THERMAL INSULATING CHARACTERISTICS OF THE COMPOSITE CORE ARE EFFECTIVELY EQUIVALENT TO THAT OF A HOMOGENEOUS CORE COMPOSED ENTIRELY OF FOAM PLASTIC MATERIAL, WHEREAS THE STRUCTURAL CHARACTERISTICS OF THE COMPOSITE CORE ARE FAR SUPERIOR THERETO.
Abstract:
Surface vessels and submarines for the transportation of large volumes of fluids are constructed of a plurality of cylindrical segments joined along their edges. The cylindrical segments serve both as the wall of the storage tanks in which the fluids transported are contained and the skin of the vessel. Webs joined to the junctures of the cylindrical segments extend across the interior of the vessel and are joined to junctures of cylindrical segments on the opposite side of the vessel.
