ABSTRACT:
A method of constructing low temperature liquefied gas tanker ships equipped with containers made of low temperature resisting material, the containers each being positioned in a hold space defined by the inner wall of a hull and a bulkhead with interposition of a heat insulating layer, characterized by forming tank assemblies each being composed of the container, said heat insulating layer covering the outer surface of the container and a water-tight layer provided over the heat insulating layer, floating the tank assemblies on the surface of the water at the positions just above the hold spaces of the hull which is kept sunk in the water, and making at least either the tank assemblies or the hull come closer to each other so that the tank assemblies are inserted into the corresponding hold spaces of the hull, whereby the construction of the tanks can be proceeded separately from and in parallel with the hull construction to spare time and the tank assemblies are mounted into the hold spaces of the hull with no requirement of heavy cranes having high lift and long reach of suspension.
