Embodiment Construction

[0035] The main idea of ​​the present invention is to change the strong beam of the exposed deck of the liquefied gas ship from the conventional arrangement under the deck to the arrangement on the deck, as shown in the attached Figure 5 to attach Figure 9 shown.

[0036] First, the deck application area is the cargo hold area of ​​the liquefied gas ship, and the ventilation mast 2 of the liquefied gas ship is arranged on the deck of the cargo hold area. According to the requirements of the specification, the height of the ventilation mast 2 of a liquefied gas ship is measured from the exposed deck 3, and the deck structure such as the deck beam 4 is turned over the exposed deck 3, which will not affect the calculation of the height of the ventilation mast 2. The height of the ventilation mast 2 It can be the same as the scheme of setting strong beams under the deck. Like this, when empty height restriction is certain, the height of the exposed deck 3 that the strong beam ...

Abstract

The invention relates to a liquefied gas carrier deck structure, which relates to the field of liquefied gas carrier design, and comprises a deck reinforcing cross beam, a deck longitudinal girder and a deck aggregate, a ventilation mast is arranged on the exposed deck, a cargo hold is arranged below the exposed deck, deck reinforcing beams, deck longitudinal girders and deck aggregates are arranged on the exposed deck, and the bottom of the exposed deck is of a smooth flat plate structure. The deck longitudinal girder and the deck aggregate are arranged in the length direction of the ship body, and the deck reinforcing cross beam is connected and perpendicular to the deck longitudinal girder. According to the invention, the influence of the space height limitation of the liquefied gas carrier on the height of the cargo tank is reduced, and under the condition of a certain ship shape size, a larger cargo tank volume and a lighter deck structure form can be designed; in addition, the invention further provides a safer and more convenient cargo tank upper surface insulation monitoring mode.

Description

technical field [0001] The invention relates to the design field of a liquefied gas ship, in particular to a deck structure of a liquefied gas ship. Background technique [0002] Liquefied gas carrier is one of many types of ships. Since the cargo is mostly cryogenic cargo, this type of ship has special requirements for cargo tanks. The main types of cargo tanks include A-type independent tanks, B-type prismatic independent tanks, and B-type Moss tanks. Tanks, C-type independent tanks and membrane tanks, etc. The present invention is mainly aimed at C-type independent tanks, and the typical cross-sections of such cargo tanks are as attached figure 1 And attached figure 2 shown. [0003] This type of cargo tank has been widely used on many real ships (especially sea-going ships). They have a common layout feature, that is, the typical cross-section of the cargo hold is the open deck, the strong beam under the deck, etc. from top to bottom. The supporting structure, the t...
