Abstract
A support deck extends on a level above the bottom of a hold of a vessel carrying low temperature liquified storage spherical tanks, from bulkheads of the hull so as to surround such spherical tanks, while a horizontal support ring projects from the outer surface of the spherical tank and is supported on the support deck through support chocks. The circular inner peripheral edge of the support deck is supported by brackets erected on the bottom plate of the hold and radially extending toward the bulkheads or by columns erected on the bottom plate of the hold. In one construction, the inner peripheral edge of the support deck has an annular girder attached to the under side thereof and such girder is supported by brackets or columns. Further, in another construction, arcuate girders are provided only in regions close to longitudinal or transverse bulkheads and supported by brackets, and adjacent girders are interconnected by an arcuate leg plate erected on the bottom plate of the hold.
