This paper analyzes the manufacturing of tee shapes for stiffening ship structure. The traditional method of deflanging hot-rolled I-beams (producing I/T shapes) has been compared to the practice of fabricating tee- shapes from plate. A group of more than 1700 I/T shapes used in the DDG-51 class vessel was used for comparisons. To produce the I/T shapes for one DDG. flanges are stripped from more than 700 tonnes (690 long tons) of I-beams. The flange material removed amounts to 25% of the weight of the original I-beams totaling approximately tonnes 172 tonnes (170 tons). This represents a material loss of 25% easily in excess of $90,000.
