Description

本発明は、低温液化天然ガスを含む炭化水素のような流体を貯蔵および運搬するためのタンクに関する。このようなタンクの例として、船舶用タンク、波荷重を受ける浮遊式海洋構造物用タンク、および重力式海洋構造物用タンク、ならびに地震に晒される陸上タンクが挙げられる。   The present invention relates to a tank for storing and transporting fluids such as hydrocarbons containing cryogenic liquefied natural gas. Examples of such tanks include marine tanks, floating marine structure tanks that receive wave loads, and gravity marine structure tanks, and land tanks that are exposed to earthquakes.

タンクは、多くの異なる形状、例えば、一般的には、球、円筒、円錐、およびシェルの形状、ならびに角柱形状に設計されている。角柱形状の主な利点は、入れ子式に互いに近接させて重ねることによって、このようなタンクが占める容積を最小限に抑えることができることにある。単純な構造の角柱タンクは、曲げ作用に依存して強度を発揮するようになっているので、構造効率が劣ることになる。シェルは、シェルの面内の直接的な張力によって強度を発揮するようになっている。これによって、同一量の材料の場合、より大きな強度がもたらされることになる。   Tanks are designed in many different shapes, for example, generally sphere, cylinder, cone and shell shapes, and prismatic shapes. The main advantage of the prismatic shape is that the volume occupied by such tanks can be minimized by nesting them in close proximity to one another. Since the prismatic tank with a simple structure is designed to exhibit strength depending on the bending action, the structural efficiency is inferior. The shell exhibits strength by direct tension in the plane of the shell. This will provide greater strength for the same amount of material.

角柱形状のより効率的な設計は、内部支柱（張力梁）を組み入れることである。内部荷重または内圧を拘束する主な手段として支柱を用いることによって、このような支柱が組み入れられた角柱タンクは、構造効率の観点から、シェル形状に匹敵するものとなる。特許文献１は、このようなタンクを開示している。この文献は、参照することによって、ここに含まれるものとする。   A more efficient design of prismatic shape is to incorporate internal struts (tensile beams). By using struts as the main means of restraining internal loads or internal pressures, prismatic tanks incorporating such struts are comparable to shell shapes from a structural efficiency standpoint. Patent Document 1 discloses such a tank. This document is hereby incorporated by reference.

構造的強度を高める以外に、支柱は、波運動によって生じたスロッシングを緩和する働きがある。スロッシングによって張力支柱に加えられる水平荷重は、梁によって吸収されることになるので、曲げを制限するために、該梁は、各交叉点において、互いに接続されねばならない。これらの梁は、交互に直交する層として組み立てられている。   In addition to increasing structural strength, the struts serve to mitigate sloshing caused by wave motion. Since the horizontal load applied to the tension struts by sloshing will be absorbed by the beam, the beam must be connected to each other at each intersection to limit bending. These beams are assembled as alternately orthogonal layers.

スロッシング力は、種々の層における支柱に角変位を生じさせる。各交差点の接続部に生じる捩れモーメントは、もし支柱が剛性拘束されているなら、該接続部の実際の幾何学的形状にもよるが、極めて大きなものになる。この問題を解決すれば、極めて大きな利点が得られるだろう。   Sloshing forces cause angular displacement in the struts in the various layers. The torsional moment generated at the connection at each intersection is very large if the column is rigidly constrained, depending on the actual geometric shape of the connection. Solving this problem will have a tremendous advantage.

国際特許出願公開第２００６／００１７１１Ａ２号パンフレットInternational Patent Application Publication No. 2006 / 001711A2 Pamphlet

本発明の目的は、交互の層内において互いに直角に交差する差梁間に接続部を設けることにある。この接続部は、交互の層内の梁を上側および下側の横方向梁に係留すると共に、該梁の相対的な角変位を吸収することができなければならない。前述した剛性拘束の問題を解消するために、接続部は、十分なせん断強度および十分な耐横曲げ性と共に、捩れ柔軟性を有するべきである。   It is an object of the present invention to provide a connection between differential beams that intersect at right angles in alternating layers. This connection must be able to anchor the beams in alternating layers to the upper and lower transverse beams and to absorb the relative angular displacement of the beams. In order to eliminate the above-described rigid constraint problem, the connection should have torsional flexibility with sufficient shear strength and sufficient lateral bending resistance.

十分なせん断強度および十分な耐横曲げ性と共に、捩れ柔軟性をもたらすために、本発明は、十字形断面を有する短柱の形態にある接続部を用いている。十字形断面は、種々の厚みを有していてもよいし、強度および疲労に関して応力分布を最適化するために、長孔または凹みを含んでいてもよい。断面は、共通軸を中心とする３つ以上の板材からなる任意のものを含むように、部分変更されてもよい。   In order to provide torsional flexibility with sufficient shear strength and sufficient lateral bending resistance, the present invention uses a connection in the form of a short column with a cross-shaped cross section. The cruciform cross section may have various thicknesses and may include slots or indentations to optimize stress distribution with respect to strength and fatigue. The cross section may be partially changed to include any one of three or more plate materials centered on a common axis.

短柱は、支柱にボルト、溶接部、または他の接続手段によって取り付けられる１つ以上の基板に溶接することによって、係留されるとよい。   The short column may be anchored by welding to one or more substrates that are attached to the column by bolts, welds, or other connecting means.

本発明の目的は、捩れに対して柔軟性を有すると共に曲げおよびせん断に対して剛性を有する多数の短柱によって、横方向支柱を互いに接続することによって、達成されることになる。本願による発明は、以下のように構成されている。   The object of the present invention will be achieved by connecting the transverse struts together by a number of short columns that are flexible to torsion and rigid to bending and shear. The invention according to the present application is configured as follows.

タンク内に用いられる交互の水平層内の互いに直交する張力梁の組立体において、互いに直交する張力梁間の交差点の少なくともいくつかは、曲げ靱性および捩れ柔軟性を有する垂直スペーサ要素によって相互接続されるようになっている。   In an assembly of orthogonal tension beams in alternating horizontal layers used in a tank, at least some of the intersections between the orthogonal tension beams are interconnected by vertical spacer elements having bending toughness and torsional flexibility. It is like that.

前述した組立体において、梁は、ウエブおよびフランジを備えていてもよい。   In the assembly described above, the beam may comprise a web and a flange.

前述した組立体において、スペーサ要素は、好ましくは、ボルト、溶接部、または任意の他の適切な固定手段によって、梁に接続されている。   In the assembly described above, the spacer element is preferably connected to the beam by bolts, welds, or any other suitable fastening means.

前述した組立体において、スペーサ要素は、好ましくは、梁のウエブまたはフランジによって、梁に接続されている。   In the assembly described above, the spacer element is preferably connected to the beam by a beam web or flange.

前述したような組立体に用いられるスペーサ要素において、前記要素は、共通軸を介して互いに交差している複数の板材に接続された２つの基板を有しており、この軸は、２つの基板の両方と交差するようになっている。   In the spacer element used in the assembly as described above, the element has two substrates connected to a plurality of plates intersecting each other through a common axis, and the axis is divided into two substrates. Crosses both.
