Abstract
A well cellar assembly is made up of axially stacked segments that have closed contour structured sidewalls. The sidewalls include inner and outer layers, an annulus between the layers, and a girder in the annulus. The girder is an elongated tubular that helically circumscribes an axis of the assembly. Upper and lower ends of the segments are profiled complementary to opposing ends of adjacent segments, and straps secure adjacent segments to one another.
