Abstract:A new form of construction for vessels designed to resist external pressure is described. Such vessels are being considered to provide a dry one-atmosphere environment to house sub-sea oil production facilities. Cylinders were made by filling the space between two thin concentric steel skins with concrete. The paper reports tests on 29 such cylinders subjected to pressures of up to 21 N/mm* (3000 lb/ in.*), equivalent to depths of 2 km (1.25 miles) below the sea surface. The results are compared with a previously published theory; agreement is good and shows that this new method is very effective for resisting external pressures.
