Independent liquid tank supporting structure

Abstract

The invention provides an independent liquid tank supporting structure, comprising an upper supporting part, a pressure-bearing insulating part and a lower supporting part. The upper supporting part comprises an upper web and an upper panel, the top end and the bottom end of the upper web are connected fixedly with a liquid tank floor board and the upper panel; the lower supporting part comprises a lower web and a lower panel, and the top end and the bottom end of the lower web are connected fixedly with the lower panel and the inner bottom of a hull; the pressure-bearing insulating part is installed between the upper panel and the lower panel and comprises laminated wood fixedly connected with the upper panel, an epoxy resin layer fixedly connected with the lower panel, and a stainless steel plate positioned between the laminated wood and the epoxy resin layer and capable of moving horizontally relative to the laminated wood; the stainless steel plate is fixedly connected with the epoxy resin layer. The independent liquid tank supporting structure can effectively bear static and dynamic loads generated by an independent liquid tank and low-temperature liquid cargoes loaded in the independent liquid tank, and has certain flexibility; relative displacements and deformation are allowed to exist between the independent liquid tank and the hull structure; the low temperature of the independent liquid tank can be effectively avoided being transmitted to the hull.

Description

technical field [0001] The invention relates to a marine supporting structure, in particular to an independent liquid tank supporting structure applicable to a liquefied gas carrier. Background technique [0002] Independent liquid tanks are used on liquefied gas carriers to carry liquefied gas at low temperature. Since the tank does not constitute a part of the hull structure, it is independent of the hull structure, and can bear its own weight and the static and dynamic loads of the internal low-temperature liquid cargo, so it is called a self-supporting independent tank. The hull structure needs to bear the weight of the independent liquid tank and its low-temperature liquid cargo. At the same time, it is also necessary to consider the dynamic load caused by the movement of the hull in waves and the movement of the cargo inside the tank. Appropriate supporting structures shall be provided to transmit and buffer such loads. In consideration of avoiding excessive stress c...

Problems solved by technology

And since the independent liquid tank is generally used to transport liquefied gas at a lower temperature, it is also necessary to avoid the danger of low-temperature brittle fracture of the metal caused by the low temperature of the hull structure caused by the transfer of low temperature between the liquid tank and the hull.
