A cryogenic liquid storage apparatus includes an inner container configured to store a cryogenic liquid, an inner holder disposed at the inner container, an outer container that surrounds the inner container, an outer holder disposed at the outer container, and a support wire that is a single body defining a closed-loop shape passing through the outer holder and the inner holder. The support wire is configured to support the inner container with respect to the outer container.

Cryogenic liquid storage apparatus

Provided is a pressure tank having a lattice structure, including: a tank body that has a high-pressure fluid accommodated therein and is manufactured to have a prismatic shape; and cell structures that are disposed in the prismatic tank body, are manufactured in a lattice form, arrive from one side wall of the tank body to the other side wall thereof facing it, and are orthogonally arranged regularly.

Prismatic pressure tank having lattice structure

Provided is an X-beam structure including: a plurality of beams extending in X-axis, Y-axis, and Z-axis directions and formed in a lattice pattern and a plurality of cross intersections at which an X-axis beam, a Y-axis beam, and a Z-axis beam meet one another, wherein in the X-beam structure in which a cross section of each beam has the geometry of a right-angled X, and the beam intersections are formed with one continuous beam and the two other joining beams are attached and welded onto the continuous beam.

X-beam structure and pressure tank having X-beam structure

The present invention relates to an apparatus for pressurizing delivery of a low-temperature liquefied material, and more particularly, to an apparatus for pressurizing delivery of a low-temperature liquefied material, which can convert the low-temperature liquefied material into a high-pressure gas and easily deliver the gas without causing changes in a composition and flashing phenomenon.

Apparatus for pressurizing delivery of low-temperature liquefied material

The present invention relates to an oil fence and to a method for storing same. The oil fence includes: a vertical support part on which an air chamber, a water chamber, and a ballast are successively disposed in the lengthwise direction thereof; a curtain part connected between the vertical support parts disposed parallel to and spaced a predetermined distance from each other in the widthwise direction thereof; and attenuation bags disposed on the upper and lower portions of the curtain part. Thus, the oil fence may prevent seawater containing oil from overflowing in spite of high waves. Also, the oil fence may stably float on the sea in spite of poor weather conditions and high waves and may be easily stored and unfolded.
