Embodiment Construction

[0028] Below we will further elaborate on the vertical support device of the present invention for the B-type fuel tank at the step of the container ship in combination with the accompanying drawings and specific embodiments, in order to understand its structural composition and application mode more clearly , but it cannot be used to limit the protection scope of the present invention.

[0029] The invention relates to a vertical support method for a B-type fuel tank at the steps of a container ship. In the method, a special vertical support device is used, and the upper part of the vertical support device is supported on the side wall of the B-type fuel tank. The position of the inclined plane, the lower part is set at the step in the container, the structure of the vertical support device includes fuel tank support, step base, laminated wood and stainless steel plate, the top of the fuel tank support passes through The bottom plate of the B-type fuel tank is welded, and the...

Abstract

The invention relates to a vertical support method for a B type fuel tank at a container ship step. According to the method, a special-purpose vertical support device is used; the upper part of the vertical support device is supported at the inclined surface of the side wall of a B type fuel tank and the lower part is arranged a step inside a container. The vertical support device includes a fueltank support, a step base, a laminated batten part and a stainless steel plate. In addition, the method includes the following steps: assembling and welding the fuel tank support on a prefabricated steel frame platform; fixing the laminated batten part and the stainless steel plate at the bottom of the fuel tank support by epoxy; carrying out normality installation on the step base and a step connecting elbow plate and welding the step base at a ship structure by full-penetration welding; setting the lower laminated batten and the stainless steel plate at the top of the step base; and after overall completion and in-place hoisting of the B type fuel tank, placing the B type fuel tank at a corresponding accurate position directly. Therefore, the vertical load of the LNG fuel tank of the container ship is supported effectively.

Description

technical field [0001] The invention belongs to shipbuilding, and in particular relates to a vertical support device and an installation method of a B-type fuel tank applied to the steps of a container ship. Background technique [0002] Independent LNG cargo tanks are divided into Type A, Type B, and Type C independent tanks. Among them, Type B tank has the characteristics of large tank capacity and flexible layout. Therefore, the application of Type B tank has a relatively large market prospect. Under the current background of stricter environmental protection pressure, LNG fuel is gradually recognized by shipping and ship design companies as a clean energy source. [0003] The type B fuel tank of a container ship for storing LNG fuel is characterized by an independent self-sustaining full-cooled cryogenic liquid cargo tank. For container ships adopting this scheme, a type B fuel tank is usually installed near the engine room. The main load of the fuel tank is For the ver...
