Abstract:
A liquefied gas treatment method for a vessel is performed by a liquefied gas treatment system for the vessel including a cargo tank storing LNG, and a main engine and a sub engine using the LNG stored in the cargo tank as fuel. The liquefied gas treatment system includes a compressor line configured to compress BOG generated in the cargo tank by a compressor and supply the compressed BOG to the engines as fuel, and a pump line configured to compress the LNG stored in the cargo tank by a pump and supply the compressed LNG to the engines as fuel. In a laden condition in which an amount of the LNG stored in the cargo tank is larger than in a ballast condition, the BOG generated in the cargo tank is supplied as fuel to at least one of the engines through the compressor line.

Provided is a pressure vessel having a vessel main body and a partition wall. The vessel main body is provided with a top wall, a bottom wall, and a peripheral wall. The top wall is provided with: a top-wall main body; a top-wall protruded part having a shape which protrudes externally from an outer surface of the top-wall main body; top-wall first-chamber-side ribs; and top-wall second-chamber-side ribs. The bottom wall is provided with: a bottom-wall main body; a bottom-wall protruded part having a shape which protrudes externally from an outer surface of the bottom-wall main body; bottom-wall first-chamber-side ribs; and bottom-wall second-chamber-side ribs. The top-wall first-chamber-side ribs and the top-wall second-chamber-side ribs each have a shape which connects with the top-wall protruded part. The bottom-wall first-chamber-side ribs and the bottom-wall second-chamber-side ribs each have a shape which connects with the bottom-wall protruded part.
Abstract:
A cuboid pressure vessel comprises a top wall, a bottom wall, and an external wall. The external wall comprises a main body including a first side wall having a first opening, and a second side wall having a second opening; a first lid secured to the first side wall so as to occlude the first opening; and a second lid secured to the second side wall so as to occlude the second opening. The bottom wall comprises a main body; and a reinforcement rib provided in an upright manner on the outer surface of the main body. The reinforcement rib is provided in an upright manner on the outer surface of an area, within the main body, which contains a central section of the main body, and which excludes four corner sections, a region adjacent to the first lid and a region adjacent to the second lid.
Abstract:
A pressure vessel having reduced weight while satisfying required design conditions has upper wall first and second ribs, upper curved surface portion first and second ribs, a bottom wall first rib with a bottom wall second rib formed on an outer surface of a bottom wall, lower curved surface portion first and second ribs, and a side wall first rib with a side wall second rib on an outer surface of a side wall. The center upper wall first rib has a center upper wall first rib center portion, a center upper wall first rib continuous portion, and a center upper wall first rib thin portion. The center bottom wall first rib has a center bottom wall first rib center portion, a center bottom wall first rib continuous portion, and a center bottom wall first rib thin portion.
Abstract:
A structural component with at least two side members has a support structure that includes a partition with multiple curved portions forming cells. The partition connects to the side members and extends between the side members at least partially along straight lines. The partition may extend along one or more straight lines from one side member to the other. One structural component is a container with a wall about the internal support structure. The container cells may be formed with a core structure. The core can include a permeable storage material and may be retained after formation, or may be removed. In some cases the container wall has generally planar surfaces, which may include surface undulations. Core structures are also provided for forming structural components. Formation can include casting a material about a core structure within a mold to form a partition extending between two or more sides.
