Abstract

Method by submarine operations at large sea depths by the use of a diver bell designed and constructed to withstand an outer pressure D1, for submersion to a sea depth where an outer pressure D3 exists which is considerably larger than D1, whereby an internal higher pressure D2 exists in the diver bell, in such a way that the difference between the pressures D3 and D2 constantly is less than the pressure D1 for which the diver bell is designated, whereby the personnel in the diver bell before submersion go through a phase of compression and after operation a phase of decompression.
