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

A fluid storage tank according to an embodiment of the present invention comprises: a first outer wall section that forms a front face in the length direction, the width direction and the height direction so as to form a space portion in which a fluid is stored; a plurality of partition plates arranged along the length direction of the first outer wall portion to divide the space portion into the plurality of sub-space portions; and an end portion located between the outermost partition plate of the plurality of partition plates and the first outer wall portion, wherein each of the partition plates is formed with a fluid through hole comprising: a gas through hole located on the top of the partition plate; and a liquid through hole located on the bottom of the partition plate so that fluids between the sub-pace portions are in communication with each other.

Fluid storage tank with plurality of partition plates

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

Provided is a natural gas liquefaction system including a natural gas storage unit, a liquefied natural gas storage unit, body, a pumping unit, a sub-cooling unit, and a first distributing and conveying unit.

Natural gas liquefaction system

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.
