Navy Experimental Diving Unit; Active: 1927: Country United States of America: Branch: United States Navy: Role: NEDU is the primary source of diving and hyperbaric operational guidance for the US Navy. Size: 120+ Part of: U.S. Naval Sea Systems Command (NAVSEA) Garrison/HQ: US Naval Support Activity, Panama City Beach, Florida: Commanders ...
1927 – Naval School, Diving and Salvage was re-established at the Washington Navy Yard. At that time the United States moved their Navy Experimental Diving Unit (NEDU) to the same naval yard. In the following years, the Experimental Diving Unit developed the US Navy Air Decompression Tables which became the accepted world standard for diving ...
hobbyist-built DPV with T500 thrusters . A DPV usually consists of a pressure-resistant watertight casing containing an underwater thruster, or a battery-powered electric motor, which drives a propeller The design must ensure that the propeller cannot harm the diver, diving equipment or marine life, the vehicle cannot be accidentally started or run away from the diver, and it remains ...
A study published in 2011 by the Navy Experimental Diving Unit reviewed the long-term health impact on the U.S. Navy diving population. [46] The divers surveyed participated as divers for an average of 18 years out of their average 24 active duty years. [46] Sixty percent of the divers surveyed were receiving disability compensation.

The US Navy has used several decompression models from which their published decompression tables and authorized diving computer algorithms have been derived. The original C&R tables used a classic multiple independent parallel compartment model based on the work of J.S.Haldane in England in the early 20th century, using a critical ratio exponential ingassing and outgassing model.
VVAL 18 is a deterministic model that utilizes the Naval Medical Research Institute Linear Exponential (NMRI LE1 PDA) data set for calculation of decompression schedules. . Phase two testing of the US Navy Diving Computer produced an acceptable algorithm with an expected maximum incidence of decompression sickness (DCS) less than 3.5% assuming that occurrence followed the binomial distribution ...
In 1896, David Watson Taylor designed and supervised construction of the Washington Navy Yard's Experimental Model Basin which was at that time the best facility in the world. That facility was a significant design testing capability before, during, and after World War I. Inadequacies in that facility led the navy to look for a new model ...
Capt. Edward Deforest Thalmann, USN (ret.) (April 3, 1945 – July 24, 2004) was an American hyperbaric medicine specialist who was principally responsible for developing the current United States Navy dive tables for mixed-gas diving, which are based on his eponymous Thalmann Algorithm (VVAL18). [1]
