Design and Structural Analysis of Alumina-Ceramic Housings for Deep Submergence Service. Fifth Generation Housings
Abstract
Two alumina-ceramic pressure housings for deep-submergence application were designed and structurally analyzed as part of a research program whose goal is to determine the structural performance of large alumina- ceramic housings. The high specific strength and modulus of alumina ceramic allows the designer to obtain lower weight-to-displacement (W/D) ratios than would be obtainable with more traditional materials such as titanium. The two large housings use a number of advanced design features such as skirted hemispheres, an epoxy-bonded central joint stiffener, a minimum clear-bore diameter requirement, GFR PEEK composite gaskets protecting the ceramic bearing surfaces, and an almost neutrally buoyant spectra fairing for impact protection. The smaller of the two housings has a 26.0-inch diameter (OD), 90-96-inch overall length, and has a calculated W/D ratio of 0.585, while the larger housing has a 33.0-inch OD, 112.84-inch overall length, and a calculated W/D ratio of 0.556. Both housings were designed for a 20,000-foot service depth (9, 030 psi external pressure). They are scheduled to be assembled, proof tested, and cyclically tested during the summer of 1993. (Author)
