Abstract
We have designed and produced small models of ceramic pressure housings for use in a free-fall floating ocean-bottom seismometer that is useful at up to 11,000 m water depth. We also present a new design method of plural through-holes for underwater connectors on ceramic hemispheres. Its design concept and the results of finite element analysis (FEA) are presented along with results of hydraulic pressure tests using 1/4-scale models. Actual-size ceramic pressure housing will be completed soon.
