Abstract

The invention discloses an LNG boat liquid dome region insulated filling method. The LNG boat liquid dome region insulated filling method comprises following steps: firstly, measuring the size of each cavity in a liquid dome insulated case framework, the diameter of a pump tower tube and the diameter of a pump tower tube hole; secondly, producing insulated filler correspondingly; and finally, carrying out filling of the insulated filler during the workshop internal field manufacturing process and the actual boat assembling process. According to the invention, the liquid dome region is filled with the produced and moulded insulated filler, the filling rate of insulation installation in the region is increased, the insulation filling quality of the liquid dome region is guaranteed, the operation risk and construction difficulty are effectively reduced, and the construction cost is saved at the same time.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an insulating filling method for a liquid dome area of ​​an LNG ship. Background technique [0002] The insulating filling of liquid dome area of ​​LNG carrier is one of the important tasks of liquid cargo tank. The traditional process adopts the method of PUF foaming, that is, injecting PUF liquid into the cavity of the insulating box where the pump tower penetrates, and the PUF will expand and harden in the cavity, and finally fill the entire cavity to achieve the effect of insulation and heat insulation. However, this method is complex in operation, high in construction cost, and high in quality risk. The specific disadvantages are as follows: [0003] 1. There are many cavities around the tube holes in the liquid dome area, with small volume and irregular structure. During the expansion process of PUF, problems such as insulation voids and insulation overflow are prone ...
