A method for liquid air and gas energy storage (LAGES) which integrates the processes of liquid air energy storage (LAES) and regasification of liquefied natural gas (LNG) at the Floating Storage, Regasification and Power (FSRP) facilities through the exchange of thermal energy between the streams of air and natural gas (NG) in their gaseous and liquid states and includes recovering a compression heat from air liquefier and low-grade waste heat of power train for LNG regasification with use of an intermediate heat carrier between the air and LNG streams and utilizing a cold thermal energy of liquid air being regasified for increase in LAGES operation efficiency through using a semi-closed CO.sub.2 bottoming cycle.

A water-borne carrier for transporting liquefied natural gas (LNG) and liquefied nitrogen (LIN). A plurality of dual-purpose cryogenic storage tanks are arranged along a length of the ship. The plurality of dual-purpose cryogenic storage tanks may contain LNG or LIN. A LNG-only cryogenic storage tank may be arranged along the length of the ship. The LNG-only cryogenic storage tank contains only LNG.

A floating cryogenic storage structure includes a hull with a center line extending in a length direction and two longitudinal side walls, the structure including at least three spherical storage tanks, two tanks being situated with their midpoints on spaced apart longitudinal positions along a first line extending in the length direction at a first side of the center line and a third tank being situated with its midpoint on a longitudinal position on a second line extending in the length direction at a second side of the center line, and a transverse distance between the first and second lines not larger than a diameter of the tanks and the longitudinal position of the midpoint of the third tank situated between the longitudinal positions of the midpoints of the first and second tanks.

The invention relates to monitoring and predicting the operation of a pump (30) arranged in a tank (3) for transporting a liquid product on board a ship (1), the pump (30) having a pump-head (31) arranged in the tank (3). A tripping risk parameter of the pump (30) is estimated at least as a function of a required net positive suction head of the pump (30), of the current filling level of the tank and of a current state of movement, which is a current sea state and/or a current state of movement of the ship, and a user is provided with an indication as a function of said tripping risk parameter.

A particular application to ships for transporting a cold liquid product, more particularly to ships for transporting LNG of the type which consume the boil-off gas for their propulsion.

A sealed and thermally insulating tank wherein the distance between two adjacent corrugations of the corrugated metal sheets of the sealing membrane is equal to a predetermined corrugation interval io, the sealing membrane comprising, around a through-element: two notched rectangular metal plates 3io wide in the first direction and 7io long in the second direction, which are symmetrical to one another, each notched rectangular metal plate having three outer edges disposed in line with a plurality of anchor plates and welded onto the first plurality of anchor plates and an inner edge having a notch formed to avoid cutting a square window through which the through-element passes, and two metal retrofit plates disposed between the non-notched portions of the inner edges of the two notched rectangular metal plates.

The present invention relates to a container transportation ship. More particularly, the present invention relates to a container transportation ship for transporting containers, characterized in that a loading space in which at least one container is loaded and a loading/unloading space configured such that an external transfer means can directly enter/exit in order to load and unload the container, are delimited on the deck of the container transportation ship; and a crane is provided to move the container in the longitudinal direction of the container transportation ship, in the transverse direction thereof, and in the upward/downward direction thereof for the purpose of loading the container on the external transfer means that has entered the loading/unloading space or unloading the container from the external transfer means.

A method for producing a sealed and thermally insulating wall for a fluid storage tank includes attaching plural anchoring elements to a support structure; installing modular formwork elements on the support structure, the modular formwork elements having a shape that protrudes relative to the support structure and that defines, with the support structure and the plurality of anchoring parts, compartments having an open side opposite the support structure; spraying insulating foam into the compartments through the open side to form plural insulating sectors made from sprayed insulating foam; arranging insulating junction elements in a stressed position in which they are stressed between the insulating sectors and capable of expanding when the insulating sectors contract, to ensure continuity of the thermal insulation; and attaching a sealing membrane to the anchoring elements.

A ship comprises: a liquefied gas storage tank; a multi-stage compressor for compressing a boil-off gas discharged from a storage tank and comprising a plurality of compression cylinders; a second heat exchanger for heat exchanging a fluid, which has been compressed by the multi-stage compressor, and thus cooling same; a first decompressing device for expanding a flow (flow a1) partially branched from the flow (flow a) that has been cooled by the second heat exchanger; a third heat exchanger for heat exchanging, by flow a1 which has been expanded by the first decompressing device as a refrigerant, the remaining flow (flow a2) of flow a after excluding flow a1 that has been branched and thus cooling same; and a second decompressing device for expanding flow a2 which has been cooled by the third heat exchanger.

A near shore liquefied natural gas (LNG) export terminal includes an LNG storage unit, a jetty and a converted hydrocarbon carrier-vessel moored against the jetty. The carrier-vessel includes a hull, at least one hydrocarbon storage tank and is provided with a natural gas processing system for liquefying natural gas. Onshore produced natural gas is supplied through a first pipeline to the natural gas processing plant on the carrier-vessel and the LNG produced by the natural gas processing system is transferred from the carrier-vessel to the LNG storage unit via a second pipeline suitable for the transfer of cryogenic fluids.
