Abstract

The invention discloses an LNG ship pump tower base helium test method. According to the method, two helium test tools are arranged on a pump tower base, and the two helium test tools are used for helium test, so that the efficiency of the method is improved by more than one time, the working difficulty is reduced, the manpower consumption is reduced, the construction time is greatly reduced, and the building efficiency of the ship is improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a helium gas test method for an LNG ship pump tower base. Background technique [0002] With the increasing demand for environmental protection, the LNG carrier market has expanded rapidly. The NO96 containment system is a stable liquid cargo tank technology, which was introduced into my country many years ago. The containment system consists of two layers of membrane and two layers of insulation, the main membrane in contact with LNG is made of invar material. Since the pump tower base runs through the construction process of the primary and secondary membranes, if the helium test of the pump tower base cannot be completed in a timely and effective manner, the production cycle will not be guaranteed at all. Contents of the invention [0003] In view of this, the present invention provides a helium test method for the pump tower base of an LNG ship to solve the problems ...
