Vertical support method for B type fuel tank at container ship step

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...
