Abstract

Provided is a liquefied gas carrier ship wherein a gangway ladder installed in a terminal at which the liquefied gas carrier ship is scheduled to dock can be bridged entirely even if an upper deck is arranged at a low position. A liquefied gas carrier (1) comprises a plurality of spherical tanks (2) for storing liquefied gas therein, arranged in the bow-stern direction and secured to the hull (5) through a skirt, and one or a plurality of tank covers (7) covering the upper half portion of the spherical tanks (2) and extending in the bow-stern direction and the beam direction, wherein a walkway (20) on which a gangway ladder installed in a terminal docked for loading / unloading work is to be bridged is provided above an upper deck (6) located between the side surface (7a) of the tank cover (7) and a side shell (9).

Description

technical field [0001] The present invention relates to a liquefied gas carrier, in particular to a liquefied natural gas carrier which stores and transports low-temperature liquefied natural gas (LNG) in MOSS spherical tanks. Background technique [0002] As a liquefied natural gas ship that stores and transports low-temperature liquefied natural gas (liquefied natural gas, LNG) in an independent spherical tank, for example, a technique disclosed in Patent Document 1 is known. [0003] In addition, in recent years, there has been a liquefied gas carrier that covers the upper half of a plurality of spherical tanks arranged along the bow direction of the ship with one continuous tank cover (see Patent Document 2). [0004] Patent Document 1: (Japanese) Japanese Patent Publication No. 5-49519 [0005] Patent Document 2: (Japanese) Special Publication No. 2005-521589 [0006] In the liquefied gas carrier disclosed in Patent Document 2, the position of the upper deck of the ga...
