    Abstract: The alkylamine composition of the present disclosure contains: an alkylamine represented by the following formula (1) in an amount of 99.5% by volume or more; and water in an amount of 10 ppm by mass or more and 100 ppm by mass or less:




    wherein N is a nitrogen atom; R1 is a C1-C10 hydrocarbon group optionally having a ring, a heteroatom, or a halogen atom; R2 and R3 are each independently a hydrogen atom or a C1-C10 hydrocarbon group optionally having a ring, a heteroatom, or a halogen atom; provided that the hydrocarbon group, when it has a carbon number of 3 or more, may have a branched chain structure or a ring structure and that the heteroatom in the hydrocarbon group is a nitrogen atom, an oxygen atom, a sulfur atom, or a phosphorus atom; further, R1 and R2, when both of them are hydrocarbon groups having a carbon number of 1 or more, may be directly bonded to each other to form a ring structure; further, R1 or R2, which is directly bonded by a double bond to form a ring structure, may form an aromatic ring in the absence of R3; R1, R2, and R3 may be hydrocarbon groups which are the same as or different from one another; and R1 has at least one hydrogen atom at α carbon bonded to the nitrogen atom.

    Abstract: Provided a LNG ship that is manufactured in a short construction period by assembling a LNG tank on land and mounting the LNG tank in a hold of the ship.A cold insulator and a membrane are affixed on an inner side of a prismatic tank to fabricate a LNG tank, which is mounted in a hold having a double hull structure. In order to prevent the prismatic tank from deforming at the time of the mounting, strength members are welded to an outer surface of the prismatic tank before a thermal insulation work for the purpose of sufficient reinforcement. After the tank is mounted in the hold, the strength members of the prismatic tank are coupled to the inner hull of the ship to integrate the LNG tank and the hull, so that the weight of a liquid cargo is supported by the prismatic tank and the hull together.

    Abstract translation: 提供一种通过在陆地上组装LNG罐并将LNG罐安装在船舶的船舶上，在短的施工期内制造的LNG船。 冷却绝缘体和膜固定在棱柱形罐的内侧以制造LNG罐，其安装在具有双层船体结构的保持架中。 为了防止棱镜箱在安装时发生变形，为了充分的加强，加强部件在进行绝热工作之前被焊接在棱柱形箱体的外表面上。 在罐被安装在搁板中之后，棱柱箱的强度构件联接到船的内部船体以将LNG罐和船体结合在一起，使得液体货物的重量由棱柱箱和 船体在一起
