Embodiment Construction

[0031]In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific embodiments shown in the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0032] Such as figure 1 As shown, for such as a large container ship, the B-type LNG fuel tank 1 is arranged below the deck of the dual-fuel container ship, figure 1 The B-type LNG fuel tank is also represented by the N label, and the LNG TANK is the B-type LNG fuel tank. The hull compartment that accommodates the B-type LNG fuel tank 1 is composed of the roof of the top, the bottom of the hull 3 and the surrounding composition of the bulkhead. Between the b...

Abstract

The invention relates to a swing-stopping and vertical-supporting composite device for a B-type LNG fuel cabin. A plurality of the swing-stopping and vertical-supporting composite devices are arranged between a bottom plate (2) of the B-type LNG fuel cabin (1) and a bottom plate (3) in a ship body, and the plurality of swing-stopping and vertical-supporting composite devices are longitudinally arranged along the center line of the cabin; and each swing-stopping and vertical-supporting composite device structurally comprises an upper support, a lower support and laminated wood between the upper support and the lower support, the upper support is connected with the bottom plate (2) of the B-type LNG fuel cabin in a welded mode, and the lower support is connected with the bottom plate (3) in the ship body in a welded mode, and the laminated wood comprises vertical laminated wood playing a supporting role and transverse laminated wood (6) playing a swing stopping role. The swing-stopping and vertical-supporting composite device has the swing stopping function and the vertical supporting function at the same time, the number of supports of the B-type LNG fuel cabin is greatly reduced, the material utilization rate is increased, and the construction operation time is shortened.

Description

technical field [0001] The invention relates to the field of ship design, in particular to a composite anti-sway and vertical support device for a B-type LNG fuel tank. Background technique [0002] As the world's environmental protection requirements for ship emissions are getting higher and higher, LNG, as a representative of clean energy, is becoming more and more popular as a ship fuel, which brings more and more demand for dual-fuel container ships, of which B-type LNG fuel tanks have their unique advantages. The size of B-type LNG fuel tanks needs to meet the voyage of the entire route of the container ship. Ship owners and operators usually require the volume of B-type LNG fuel tanks to be as large as possible. Due to the large size, the flat bottom area of ​​the B-type LNG fuel tank is relatively small, and because the B-type tank is an independent tank, it is necessary to consider the combination of vertical support, anti-rolling, anti-pitching and other types of su...
