Title: Gas Flows Supporting Umbilical Diving - Requirements and Measurements
Author: Clarke, JR
Abstract: This report compiles information from various publications and letters about the MK 3 LWDS umbilical-supplied breathing system. New analyses were also conducted with various computational methods to describe the system and the gas supplies delivered to three divers at the maximum depth of the system, 190 fsw. One calculation method for steady state gas flow was based on equations for airflow in pipes. Electrical models were used to describe steady state flow with no divers or dynamic flow with divers. The models were solved by the PSPICE differential equation solver. All methods consistenily illustrated that flow restriction occurs in 600-foot umbilicals and limits the emergency gas supply available at 190 fsw.
