Title: Theoretical Consideration on the Decompression of Rescued Submarine Personnel
Author: Greene, KM
Abstract: This treatise is a theoretical discussion of certain aspects of the problem of decompressing personnel rescued from a sunken submarine the atmosphere of which has been pressurized above one atmosphere absolute. Provision has been made in the design of the U.S. Navy's Deep Submergence Rescue Vehicle (DSRV), the Deep Dive System MKII Mod 1 (DDS), and the ASR 21 class Submarine Rescue Vessel, to allow a transfer of personnel under pressure from the disabled submarine to the deck decompression chamber (DDC) of the DDS MKII via the DSRV. It is therefore of interest to consider how these rescued personnel are to be decompressed in the DDC. Decompression procedures should be pre-planned to lessen the likelihood of error or omission. The following design factors are pertinent: Rescue response time: 24 to 48 hours DSRV internal pressure capability: 132 FSW gage Transfer time (from submarine to DDC): 6-12 hours DSRV life support system: normoxic N2/02 or air DDC atmosphere: He/02 or air If the internal pressure of the submarine has been increased by sea water leak or by salvage air pressurization to control flooding, the 24- to 48-hour rescue response delay could allow the submarine personnel to become saturated with nitrogen at the ambient partial pressure . We must consider -decompression from 132 FSW saturation, but we cannot predict [Editor's note: Page 1]
