The disaster in which the Russian submarine Kursk sank in August 2000 brought the submarine operators around the world to a new focus on submarine safety.


There has been a long history of successful submarine escape and rescues dating back to 1915 when the submarine U3[1] sank and leading onto 1931 when the McCann Rescue Bell[2] was designed and built. In 1939 the McBell was used successfully recovering 33 survivors from “Squalls”[3].

During the 1960s the loss of two American nuclear submarines US Thresher and Scorpion were both lost in water that made rescue impossible. Further development of the submarine rescue systems were made using the deep submerged rescue vehicle (DSRV) which was a manned mini-sub that mates with the sunken submarine and could transfer and carry up to 22 rescuees at a time.


The submerged disabled submarine is known as DISSUB.  Escape or rescue is the process that is used today.  There is no alternative only today we have greater knowledge and better technical knowhow and improved equipment.

If a disastrous event happened today the process of recovery would be something like:

Stage One:  Send down a reconnaissance ROV to locate the DISSUB and record all visual data to evaluate the manned mission requirements. 

Stage Two:  Crew decompression upon recovery.  Transfer under pressure (TUP) of the rescuees from the stricken submarine to the DSRV and lock on to the TUP System.

Transfer under pressure (TUP) capability is a modern requirement of Submarine Rescue Systems, since it has been established that in most cases the survivors will most likely be exposed to higher than normal atmospheric pressure similar to that of divers during diving operations, this will also be over an extended period due to the length of the rescue operations which creates an even greater decompression period.  This will lead to a longer period of decompression than normal.

Therefore the requirements for large multi-place surface decompression chambers to be on site with a TUP facility.  These multi-compartment decompression chambers will be used for accelerated air and nitrox decompression, decontamination and medical treatment as required.

Today there are over 40 countries now operating submarines and there have been over 10 submarine sinkings since the 1960’s therefore Submarine Rescue is essential.
