Description

本発明は、原油、灯油、液状の化学薬品などを運搬する液体運搬船に関する。   The present invention relates to a liquid carrier that carries crude oil, kerosene, liquid chemicals, and the like.

液体運搬船としては、例えば、油槽船を挙げることができるが、従来の油槽船は、原油の揚げ荷用配管装置及び積込み用配管装置が全て配管で構成されていた。すなわち、従来の油槽船１００は、図５に示すように、暴露部上甲板１０１上、及び貨物油タンク１０２内に配管１０３を配置していたが、これらの配管１０３は、図６に示すように、門型状の受け台又は馬１０４上に設置され、かつ、金属製のバンド１０５によって前記受け台又は馬１０４上に固定されていた。更に、配管１０３どうしは、フランジなどの継ぎ手（図示せず）を介して接続されていた。図中、符号１０６は、タンク底部を示している。   As the liquid carrier ship, for example, an oil tank ship can be cited, but in the conventional oil tank ship, the piping device for unloading crude oil and the piping device for loading are all configured by piping. That is, as shown in FIG. 5, the conventional oil tanker 100 has the pipes 103 arranged on the exposed part upper deck 101 and in the cargo oil tank 102. These pipes 103 are shown in FIG. 6. In addition, it was installed on a gate-shaped cradle or horse 104 and fixed on the cradle or horse 104 by a metal band 105. Furthermore, the pipes 103 are connected to each other through a joint (not shown) such as a flange. In the figure, reference numeral 106 denotes a tank bottom.

上記配管の取り付けは、タンク構造の製作と同時に行うのが困難であるため、別途、配管工事が必要であり、その分、工事の増加が不可欠となっている。また、従来の配管工事は、配管、受け台、馬、バンド、ボルト・ナット、パッキンなどの多数の装置や部品の発注、納入、管理が必要となり、配管取り付け作業時には、部品の多さが煩雑な作業を強いると云う難点があった。また、従来の配管方式では、貨物油タンクの洗浄時に、受け台や馬などの上にスラッジが堆積することがあった。   Since it is difficult to install the pipes at the same time as the production of the tank structure, it is necessary to separately perform piping work. In addition, conventional piping work requires the ordering, delivery, and management of a large number of devices and parts such as piping, cradle, horse, band, bolt / nut, and packing. There was a difficult point that it was difficult to work. In the conventional piping system, sludge may accumulate on a cradle or a horse when the cargo oil tank is washed.

他方、海洋汚染条約（ＭＡＲＰＯＬ）の改正を受けて、二重船底の内殻の内周面上に、オイルタンカー（油槽船）の長手方向にトンネルを設け、このトンネル内に貨油管（配管）を配管した二重船殻構造のオイルタンカーが提案されている（例えば、特許文献１参照。）。   On the other hand, in response to the revision of the Marine Pollution Convention (MARPOL), a tunnel is installed in the longitudinal direction of the oil tanker (oil tanker) on the inner peripheral surface of the inner shell of the double ship bottom, and a coin oil pipe (pipe) is installed in this tunnel. An oil tanker with a double hull structure is proposed (see, for example, Patent Document 1).

この特許文献１によれば、ドライな環境で貨油管（配管）のメンテナンスなどを行うことができるかも知れないが、貨油管（配管）を門型状の受け台又は馬上に設置してバンドで固定している場合には、配管、受け台、馬、バンド、ボルト・ナット、パッキンなどの各種部品の調達や貨油管（配管）の取り付け作業が煩雑になると云う問題がある。
特開平８−１１３１８９号公報 According to this patent document 1, it may be possible to perform maintenance of a freight oil pipe (pipe) in a dry environment, but the freight oil pipe (pipe) is installed on a gate-shaped cradle or horse and is used with a band. In the case of fixing, there is a problem that procurement of various parts such as piping, cradle, horse, band, bolt / nut, packing, and installation work of a coin oil pipe (piping) become complicated.
