Abstract
Description
また、近年では、船首尾方向に沿って配置された複数個の球形タンクの上半部を、一つの連続したタンクカバーで覆うようにした液化ガス運搬船も知られている(特許文献2参照)。 As a liquefied gas carrier ship that stores and transports natural gas (LNG) liquefied at a low temperature in a moss type spherical tank, for example, one disclosed in
In recent years, a liquefied gas carrier ship in which the upper half of a plurality of spherical tanks arranged along the stern direction is covered with one continuous tank cover is also known (see Patent Document 2). .
本発明に係る液化ガス運搬船は、内部に液化ガスを貯蔵するとともに、船首尾方向に沿って配置され、かつ、スカートを介して船体に固定された複数個の球形タンクと、これら球形タンクの上半部を覆うとともに、船首尾方向および船幅方向に沿って延びる一つの、または複数個のタンクカバーとを備えた液化ガス運搬船であって、前記タンクカバーの側面と船側外板との間に位置する上甲板の上方に、荷役作業を行うために着岸したターミナルに設置されているギャングウェイラダーが架け渡されるウォークウェイが設けられている。 The present invention employs the following means in order to solve the above problems.
The liquefied gas carrier ship according to the present invention stores a liquefied gas therein, and is arranged along the bow-stern direction and fixed to the hull via a skirt, and a top of these spherical tanks. A liquefied gas carrier ship that covers one half and includes one or a plurality of tank covers that extend along the stern direction and the width direction of the tank, between the side surface of the tank cover and the ship side skin A walkway over which a gangway ladder installed at a terminal docked to carry out cargo handling work is provided above the upper deck.
これにより、電線、油配管、水配管、消火配管、圧縮空気配管等の保守・点検作業が容易に行えるようになり、メンテナンス性を向上させることができる。 According to such a liquefied gas carrier, it is arranged in a space (for example, a space surrounded by a foundation deck, an upper deck, a longitudinal bulkhead, and a ship side shell) formed below the upper deck. Electric wires, oil piping, water piping, fire extinguishing piping, compressed air piping, etc. can be placed in an open space (a space formed between the walk deck and the upper deck) formed below the walk deck. .
As a result, maintenance / inspection work for electric wires, oil piping, water piping, fire extinguishing piping, compressed air piping, and the like can be easily performed, and maintainability can be improved.
これにより、ウォークウェイを設置することによる船体重量および製造コストを低減させることができ、ウォークウェイを設置するのに要する作業工程を減少させることができる。 According to such a liquefied gas carrier, the walkway is partially provided as necessary, for example, only at the central portion in the longitudinal direction of the tank cover.
Thereby, the hull weight and manufacturing cost by installing a walkway can be reduced, and the work process required for installing a walkway can be reduced.
なお、「着岸が予定されているターミナル」とは、就航後に本船の着岸が予定されているターミナルおよび/または既に就航している本船が、航路変更等により着岸することになった新たなターミナル等のことをいう。 In the liquefied gas carrier, a height H (m) from the ship bottom to the upper surface of the walkway is higher than a height D (m) +2 (m) from the ship bottom to the upper surface of the upper deck, and 40 (m It is more preferable that the height is set so that all of the gangway ladders installed at the terminal scheduled to be docked can be bridged.
“Terminal scheduled to berth” means a terminal where the vessel is scheduled to berth after service and / or a new terminal that has already been in service due to a change of route, etc. I mean.
