Support structure between C-shaped liquid cargo tank and inner bottom of hull and installation method thereof

Abstract

The invention provides a support structure between a C-shaped liquid cargo tank and an inner bottom of a hull and an installation method thereof. The support structure comprises three groups of supporting bases, namely a fixed supporting base matched by a first upper supporting base and a first lower supporting base and two sliding supporting bases matched by second upper supporting bases and second lower supporting bases, and the fixed supporting base is arranged between the two sliding supporting bases; each crosser on the three groups of supporting bases is installed on the bottom surface of the liquid cargo tank in advance, and then the whole liquid cargo tank is hoisted in each crosser groove on the hull and the inner bottom of the hull by a portal crane so as to be supported in a matched mode; and each crosser groove is arranged on a panel of the inner bottom of the hull, and the panel is fixed on the inner bottom of the hull by a plurality of ribbed plates and support webs. According to the support structure and installation method thereof provided by the invention, the installation work of each crosser is finished before the liquid cargo tank is hoisted and installed on the hull, thereby shortening the adjusting time and positioning time of the liquid cargo tank with the first and second upper supporting bases, saving the cost and time for installation of the liquid cargo tank and improving the work efficiency.

Description

technical field [0001] The invention relates to the field of installation and cooperation between a C-type liquid cargo tank and a ship hull in the field of shipbuilding, and more specifically relates to a support structure and an installation method between a C-type liquid cargo tank and the inner bottom of a ship. Background technique [0002] In the field of shipbuilding, the structural design of semi-cooled and semi-pressurized liquefied gas carriers is special compared with other types of ships. The liquid tank of a large semi-refrigerated and semi-pressurized liquefied gas carrier is a C-type liquid cargo tank, which is placed in the main hull and supported by a saddle support structure. The weight of the entire C-type liquid cargo tank and its cargo is supported by the saddle The structure is transmitted to the main hull structure; at the same time, considering the movement of the main hull in waves and the dynamic load caused by the movement of cargo inside the C-typ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional technology, there is a double support structure between the C-type liquid cargo tank and the inner bottom of the hull. The double support structure includes a fixed saddle and a sliding saddle. Due to the high installation accuracy requirements of the double support structure, the positioning It takes a long time, and at the same time, there are insufficient thickness control of epoxy resin and enhanced shock absorption effect of skids
