Embodiment Construction

[0034] 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.

[0035] Such as figure 1 As shown, the present invention is a composite anti-sway and anti-floating device for a B-type LNG fuel tank. The B-type LNG fuel tank N is arranged below the deck of a dual-fuel container ship. figure 1 The LNG TANK in is the B-type LNG fuel tank, and the hull compartment accommodating the B-type LNG fuel tank N is composed of the top plate of the inner cabin, the bottom plate of the hull and surrounding bulkheads. A plurality of ant...

Abstract

The invention relates to a swing-stopping and floating-stopping composite device for a B-type LNG fuel cabin. The swing-stopping and floating-stopping composite device structurally comprises an upper support, a lower support and laminated wood, wherein the upper support is welded and fixed with a top plate of an inboard cabin, the lower support is welded and fixed with a top plate of the B-type LNG fuel cabin, a clamping groove along the center line of a ship body is formed in the bottom part of the upper support, the top part of the lower support extends into the clamping groove, a gap is reserved between the top part of the lower support and the top part of the clamping groove, gaps are reserved between the two transverse sides of the top part of the lower support and the two side walls of the clamping groove, and a laminated wood block is arranged in the gap between the clamping groove of the upper support and the top part of the lower support. The swing-stopping and floating-stopping composite device composite device provided by the invention has two functions of swing stopping and floating stopping at the same time, the number and specification of supports at the top part of the B-type LNG fuel cabin are 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 an anti-rolling and anti-floating composite 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 The LNG fuel tank has its unique advantages. The size of the B-type LNG fuel tank needs to meet the voyage of the entire route of the container ship. The ship owner and operator usually require the volume of the B-type LNG fuel tank to be as large as possible. [0003] When considering the damage of the hull and seawater pouring into the gap between the inner shell of the hull and the B-type LNG fuel tank, if the B-type LNG fuel tank is empty at this time, it will be subject to the huge buoyancy of the seawa...
