dc.description.abstract Current Combat Swimmer missions involve multiple depth dives using air where long periods of time are spent at depths 30 FSW and shallower. Current dive procedure requires using the deepest depth for the total dive time unless at least 10 min intervals are taken at 1 ATA in which case repetitive dive procedures may be used. Also, current repetitive dive procedures only addresses times up to 350 min. This report first reviews the origin of the current Air Repetitive Diving Procedures and examines in detail how the No-Decompression Repetitive Group Designations, the Residual Nitrogen Timetable, and the Surface Interval Credit Table were calculated. In addition, several errors and inconsistencies in these tables are pointed out and discussed. Then, a procedure is developed based on using Repetitive Air Diving techniques for doing multiple level dives where no surface interval is taken. Additions and/or changes in current repetitive diving procedure necessary to accomplish this include extension of the Residual Nitrogen Timetable to a depth of 30 FSW and extension of repetitive group designation at 30 FSW from Group L to Group 0. This Combat Swimmer Multi-level Dive Procedure (CSMD Procedure) involves dividing the dive up into alternating intervals 30 FSW and shallower and deeper than 30 FSW. For each interval a repetitive group is calculated and used to find a residual nitrogen time for the next interval. en_US
