Vertical supporting structure for cargo tank and inboard bottom of full-refrigerated liquefied gas carrier and mounting method of vertical supporting structure

Abstract

The invention provides a vertical supporting structure for a cargo tank and an inboard bottom of a full-refrigerated liquefied gas carrier. The vertical supporting structure comprises an upper support seat, a lower support seat, a first bed timber and a second bed timber, wherein the upper support seat is arranged on the cargo tank side of full-refrigerated liquefied gas carrier; the lower support seat is arranged on the inboard bottom side of full-refrigerated liquefied gas carrier; the upper and the lower support seats are the same in structure; each support seat comprises a baseplate and two panels on one side of the baseplate; a support toggle plate is arranged between the baseplate and the panels; a rib plate perpendicular to the baseplate is arranged on the other side of the baseplate; bed timber grooves are respectively arranged on the panels; a lifting jack supporting platform is arranged at two ends of each panel; the first bed timber is arranged in bed timber groove on the upper support seat; the second bed timber is arranged in a bed timber groove of the lower support seat; and the first bed timber is in contact with the second bed timber. The vertical supporting structure between the cargo tank and the inboard bottom provides convenience for mounting the cargo tank, and saves time and cost for mounting.

Description

technical field [0001] The invention relates to the support problem between the liquid cargo tank and the inner bottom of the ship, and more specifically relates to a vertical support structure and an installation method for the liquid cargo tank of a large-scale fully cooled liquefied gas ship. Background technique [0002] Compared with other types of ships, the structural design of the fully cooled liquefied gas carrier is special. The liquid tank of a large fully cooled liquefied gas carrier is a type A independent liquid cargo tank, which does not constitute a part of the hull structure. It is placed in the cargo hold and supported by a vertical support. The entire type A independent liquid tank and its contents The weight of the cargo is transmitted to the main hull structure through the supporting structure, and the movement of the main hull in the waves and the dynamic load caused by the movement of the cargo inside the tank also need to be considered. The force of ...

Problems solved by technology

When the traditional support structure decides to install the liquid cargo tank, due to the high installation accuracy requirements and long positioning time, at the same time, there are insufficient thickness control of the epoxy mastic and enhanced shock absorption effect of the skids, and it is waiting for the epoxy mastic to cure. The method is to leave it still after hoisting by the crane. Since the epoxy cement needs more than 80 hours to fully cure, the support structure makes the installation method have the defects of low efficiency and long service life of large cranes.
