Abstract: The present invention provides a control device that includes a first temperature detection unit that detects a partition wall temperature of a tank main body in which liquefied gas is contained, and a second temperature detection unit that detects a temperature of a skirt that supports the tank main body. The control device further includes a temperature difference acquisition unit that acquires a temperature difference between the partition wall temperature detected by the first temperature detection unit and the temperature of the skirt which is detected by the second temperature detection unit, and a determination unit that determines whether or not a joint between the tank main body and the skirt is rapidly cooled by the liquefied gas on the basis of the partition wall temperature and the temperature difference.

Abstract: Method for the production of a high-resistance tank has an initial stage in which a closed metal vessel is formed, followed by a second stage in which the walls of the vessel are subjected to a mechanical pre-tensioning treatment in both the axial and radial directions, up to a predetermined value. This mechanical treatment has a stage in which the tank is enclosed inside a mould of suitably larger dimensions. A liquid is then introduced in the tank and pressurized until the tank walls are dilated and stretched to a point where they encounter the mould inner surface. Subsequently, the outside of the tank is coated with one or more layers of composite material, so as to complete the construction of the tank, upon which a final auto-frettage treatment is carried out. The type of steel to be used is AISI 304, preferably in its more weldable AISI 304L version.

Abstract: Systems and methods for optimizing the recondensation of boiloff gas in liquid natural gas storage tanks are presented. In especially preferred aspects of the inventive subject matter, BOG from a storage tank is condensed using refrigeration content of a portion of LNG sendout in a direct or indirect manner, and the BOG condensate and LNG sendout portion are combined to form a subcooled stream that is then combined with the balance of the LNG sendout, to be fed to a high pressure pump. Contemplated recondensation operations advantageously occur without using otherwise needed large volume recondensers. Moreover, the condensing and subcooling operations are decoupled from the LNG sendout rate.
