Thalmann Algorithm Decompression Table Generation Software Design Document

Abstract

The Thalmann Exponential-Linear Decompression Algorithm (EL-DCA) was developed with the VVal-18 and HVal-21 parameter sets at Navy Experimental Diving Unit (NEDU) to produce 0.7 atmospheres absolute (ata) constant PO2-in-N2 and 0.7 ata constant PO2-in-He decompression tables. The original EL-DCA was extensively modified at NEDU to develop MK 16 MOD 1 N2-O2 and He-O2 decompression tables and Submarine Rescue and Diving Recompression System Operator/Tender decompression tables. The EL-DCA was further modified and used with a modified VVal-18 parameter set, designated VVal-18M, to produce an integrated set of air diving decompression tables for Revision 6 of the U.S. Navy Diving Manual. This report describes the design of the EL-DCA software that was used to produce the integrated air decompression tables and documents the software modifications made since publication of Thalmann's original reports.
