The Deep Diving System (DDS) is a versatile tool in diving and its application is
extensive. Most of today’s systems employ a multilock deck decompression
chamber (DDC) and a personnel transfer capsule (PTC).
Non-Saturation Diving. Non-saturation diving can be accomplished with the
PTC pressurized to a planned depth. This mode of operation has limited real
time application and therefore is seldom used in the U.S. Navy.
Saturation Diving. Underwater projects that demand extensive bottom time
(i.e., large construction projects, submarine rescue, and salvage) are best conducted
with a DDS in the saturation mode.
Conventional Diving Support. The DDC portion of a saturation system can be
employed as a recompression chamber in support of conventional, surfacesupplied
