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.
A procedure for dealing with omitted decompression stops is described in the US Navy Diving Manual. In principle the procedure allows a diver who is not yet presenting symptoms of decompression sickness, to go back down and complete the omitted decompression, with some extra time added to deal with the bubbles which are assumed to have formed ...
Since then books titled Diving Manual or U.S. Navy Diving Manual have been published several times, each one updating the content of the previous version. The amount of information provided has tended to increase over the years, the 1905 edition had approximately 66 pages, while Revision 7 (2016) has 992 pages in 18 chapters; the manuals are ...
A US Navy work diver is lowered to the sea bed during a dive from the USNS Grasp off the coast of St. Kitts. Preparing to raise a mine from the seabed. A clearance diver was originally a specialist naval diver who used explosives underwater to remove obstructions to make harbours and shipping channels safe to navigate, but the term "clearance diver" was later used to include other naval ...

Navy Regulations began with the enactment by the Second Continental Congress of the "Rules for the Regulation of the Navy of the United Colonies" on November 28, 1775. [1] The first issuance by the United States Government which covered this subject matter was "An Act for the Government of the Navy of the United States," enacted on March 2 ...
The Bluejacket's Manual is the basic handbook for United States Navy personnel. First issued in 1902 to teach recruits about naval procedures and life and offer a reference for active sailors, it has become the "bible" for Navy personnel, providing information about a wide range of Navy topics. The current edition is the 26th, published in 2023.
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 ...
