Definitions
- the present disclosure relates to liquefied gas tanks and ships.
- the present application claims priority with respect to Japanese Patent Application No. 2020-027061 filed in Japan on February 20, 2020, the contents of which are incorporated herein by reference.
- a cargo tank for liquefied gas in a ship carrying liquefied gas such as liquefied natural gas, includes a tank body for storing liquefied gas and a heat insulating material provided so as to cover the outer peripheral surface of the tank body.
- the present disclosure has been made to solve the above problems, and an object of the present disclosure is to provide a liquefied gas tank and a ship capable of increasing the capacity of the tank while suppressing the cost increase.
- the liquefied gas tank includes a tank body, an intermediate layer, and a thin film layer.
- the tank body forms an accommodation space inside.
- the intermediate layer covers the inner surface of the tank body.
- the intermediate layer is formed of a heat insulating material having a thermal conductivity lower than that of the tank body.
- the thin film layer covers the inner surface of the intermediate layer.
- the thin film layer is capable of containing liquefied gas in a liquid-tight manner.
- the ship according to the present disclosure includes a hull and a liquefied gas tank as described above provided on the hull.
- FIG. 1 is a plan view showing the overall configuration of a ship according to the embodiment of the present disclosure.
- FIG. 2 is a semi-cross-sectional view of the liquefied gas provided on the ship as viewed from the stern direction.
- the ship 1A of the embodiment of the present disclosure carries liquefied gas such as liquefied natural gas, liquefied petroleum gas, liquid carbon dioxide, and liquid ammonia.
- the ship 1A includes at least a hull 2 and a liquefied gas tank 20A.
- the hull 2 has a pair of side sides 3A and 3B, a ship bottom 4, and an upper deck 5, which form the outer shell thereof.
- the side 3A and 3B are provided with a pair of side outer plates forming the left and right side respectively.
- the ship bottom 4 is provided with a ship bottom outer plate connecting these side 3A and 3B. Due to the pair of side 3A and 3B and the bottom 4, the outer shell of the hull 2 has a U shape in a cross section orthogonal to the stern direction Da.
- the upper deck 5 is an all-deck exposed to the outside. In the hull 2, an upper structure 7 having a living area is formed on the upper deck 5 on the stern 2b side.
- the hull 2 has a cargo loading section (hold) 8 formed on the bow 2a side of the superstructure 7.
- the cargo loading section 8 is recessed toward the bottom 4 below the upper deck 5 and opens upward.
- a plurality of liquefied gas tanks 20A are provided in the cargo loading section 8. These plurality of liquefied gas tanks 20A are arranged side by side in the stern direction Da.
- the upper portion 20a of each liquefied gas tank 20A projects upward from the upper deck 5 of the hull 2.
- the upper portion 20a of the plurality of liquefied gas tanks 20A is covered with a tank cover 25 provided on the upper deck 5.
- An external heat insulating material (not shown) that suppresses heat input from the outside may be provided between the inner surface of the tank cover 25 and the outer surface of the liquefied gas tank 20A.
- the liquefied gas tank 20A is supported by the skirt 30.
- the skirt 30 has a cylindrical shape extending in the vertical direction Dv, and its lower end is fixed on a foundation deck portion 9 provided at the bottom of the cargo loading section 8.
- the liquefied gas tank 20A stores the liquefied gas in the storage space S inside the liquefied gas tank 20A.
- the temperature and pressure of the liquefied gas contained in the storage space S are as follows: in the case of liquefied natural gas, the temperature is -163 ° C and the pressure is 4 bar, and in the case of liquefied petroleum gas, the temperature is -50 ° C and the pressure is 18 bar. In the case of liquid carbon dioxide, the temperature is ⁇ 35 ° C. and the pressure is 19 bar, and in the case of liquid ammonia, the temperature is ⁇ 50 ° C. and the pressure is 5 bar.
- the liquefied gas tank 20A includes a tank main body 21A, an intermediate layer 22, and a thin film layer 23.
- the tank body 21A forms the outer shell of the liquefied gas tank 20A.
- the tank body 21A forms a storage space S inside.
- the tank body 21A has a spherical shape.
- the tank body 21A includes a lower half portion 21a and an upper half portion 21b.
- the lower half portion 21a is hemispherical in the lower portion of the tank body 21A.
- the lower half portion 21a is a hemispherical shape having a constant radius of curvature.
- the axis a is a virtual line extending in the vertical direction Dv through the center of the tank body 21A and eventually the liquefied gas tank 20A.
- the tank body 21A is arranged so that its axis a is located at the center of the hull 2 in the stern direction Da and the center of the ship width direction Dw (see FIG. 1).
- the arrangement of the liquefied gas tank 20A in the hull 2 is not limited to this case.
- the upper half portion 21b is provided above the lower half portion 21a.

- the liquefied gas tank 20A includes a tank body 21A, an intermediate layer 22, and a thin film layer 23.
- the tank body 21A forms a storage space S inside.
- the intermediate layer 22 is formed of a heat insulating material 22 m having a low thermal conductivity.
- the intermediate layer 22 covers the inner surface 21f of the tank body 21A and forms a storage space inside.

- the pressure due to the liquefied gas contained inside the thin film layer 23 is received by the intermediate layer 22 and the tank body 21A via the thin film layer 23.
- the tank body 21A functions as a strength member of the liquefied gas tank 20A that receives the internal pressure of the liquefied gas. As a result, out-of-plane deformation of the thin film layer 23 can be suppressed.
- the heat transfer from the low temperature liquefied gas to the tank body 21A can be suppressed by the heat insulating material 22m, and the temperature drop of the tank body 21A can be suppressed.
- the heat insulating material 22 m having a thermal conductivity smaller than that of the tank body 21A can suppress the invasion of heat from the outside of the liquefied gas tank 20A and suppress the temperature rise of the liquefied gas.

Therefore, when the thin film layer 23 undergoes thermal shrinkage in response to a temperature change due to the liquefied gas, the thin film layer 23 is not constrained by the intermediate layer 22, and displacement due to the thermal shrinkage can be allowed. As a result, it is possible to prevent stress from being generated in the thin film layer 23 due to heat shrinkage.

- stainless steel or Invar material for the thin film layer 23 in this way, for example, even when liquid ammonia or the like is stored in the liquefied gas tank 20A as the liquefied gas, the contact between the liquefied gas and the thin film layer 23 causes the thin film layer 23 to come into contact with each other. It is possible to suppress the occurrence of a chemical reaction.

本願は、2020年2月20日に日本に出願された特願2020-027061号について優先権を主張し、その内容をここに援用する。 The present disclosure relates to liquefied gas tanks and ships.
The present application claims priority with respect to Japanese Patent Application No. 2020-027061 filed in Japan on February 20, 2020, the contents of which are incorporated herein by reference.
図1、図2に示すように、本開示の実施形態の船舶1Aは、液化天然ガス、液化石油ガス、液体二酸化炭素、液体アンモニア等の液化ガスを運搬する。この船舶1Aは、船体2と、液化ガスタンク20Aと、を少なくとも備えている。 FIG. 1 is a plan view showing the overall configuration of a ship according to the embodiment of the present disclosure. FIG. 2 is a semi-cross-sectional view of the liquefied gas provided on the ship as viewed from the stern direction.

図3に示すように、薄膜層23は、中間層22の内面22fに対して接合されておらず、熱変形等の際に中間層22に対して独立して変位可能とされている。薄膜層23は、熱変形を吸収する変形吸収部27を備えている。この変形吸収部27は、例えば、図3に示す断面における薄膜層23の周方向Dcの一部に設けられている。変形吸収部27は、薄膜層23の周方向Dcの一部を液化ガスタンク20Aの径方向Drの外側と内側とに交互に蛇腹状に折り曲げて形成されている。変形吸収部27は、例えば、液化ガスタンク20Aの中心O1周りに環状に形成され、液化ガスタンク20A内に液化ガスを収容した場合に薄膜層23に生じる熱収縮を吸収する。より詳しくは、薄膜層23が周方向Dcに熱収縮すると、蛇腹状の変形吸収部27が伸長するように変形する。この変形吸収部27が、薄膜層23の熱収縮を吸収することにより、薄膜層23には過大な熱応力が発生することはない。なお、変形吸収部27は、一つの薄膜層23の複数箇所に設けてもよい。 FIG. 3 is a cross-sectional view showing a displacement absorbing portion formed in the thin film layer of the liquefied gas tank.

また、低温の液化ガスからタンク本体21A、21Bへの熱伝達が防熱材22mによって抑えられ、タンク本体21A、21Bの温度低下が抑えられる。これにより、タンク本体21A、21Bに低温靱性に対する要求が緩和される。加えて、低温靱性に関する要件が緩和されることから、タンク本体21A、21Bの厚さ制限が解除され、タンク本体21A、21Bの厚さT1を増大させることが可能となる。その結果、タンク本体21A、21Bに、より廉価な材料を使用することが可能となる。また、タンク本体21A、21Bの厚さT1を増大させることで、タンク本体21A、21Bの大型化も可能となる。
また、タンク本体21A、21Bよりも熱伝導率の小さい防熱材22mにより、液化ガスタンク20A、20Bの外部からの熱の侵入を抑え、低温な液化ガスの温度上昇を抑えることもできる。これにより、液化ガスタンク20A、20Bの外部に設置する外部防熱材(図示無し)の量を減らすことができ、製造コストを抑えることが可能となる。
このようにして、コスト上昇を抑えつつ、タンクの大容量化を図ることが可能となる。 The liquefied
