Sub Submarine Boat
Steam Engines came before diesel engines, fuel costs are high, water isn't, right?
the Swedes developed an AIP system, which is a large tank of oxygen carried on board a submarine that allowed the diesel engines to continue to operate even when the sub was submerged. (Air Independent Propulsion). Before this was developed, the sub was dependent upon its supply of batteries for operating power while submerged, and was limited to the number of hours it could remain submerged, with the AIP, the sub can remain for up to one month and then it still has the batteries for another 12 hours of being submerged before returning to the surface to charge the batteries.
Why couldn't the diesel engines of today for shrimp boats and other types of transatlantic ships switch over to all steam power for their propulsion. No fossil fuels needed to provide the heat, just a new source of unlimited electricity that is 100%self-contained, would owners of large fleets be interested in such a system, especially when they slashed their fuel costs down to ZERO? Something has to be done!
I see someone pulled there screen name from a well known , and very well liked comedian.
To answer your question, the air supply that you mention is used to provide air for the diesel engines aboard those subs. That air, other than helping to keep the crew alive is worthless without the fuel the engines use, as well as the engines to provide propulsion to the sub. It is called Air Independent propulsion, because the air tank takes the place of a snorkel, which many subs used to use (the Germans in WW2 came up with that idea), or running on the surface with their air induction vents open. So, just an air supply for the fishing fleets would do them no good. Besides, why carry an air tank when you have air all around you. It still takes some kind of pump to fill the tank, AND some kind of engine to run the pump. Great for the Swedes to have an air supply for running under water.
The fishing fleets will be needing fossil fuels for awhile yet. As for steam, it's an idea, but the cost to change over would be more than what it would be worth. You would also need someone who knows how to run the engine, where with a diesel, that requirement is not as great.

Submarine Type VII U-boat
Military help needed please: Submarine Service?
Hello. I am hoping to join the Royal Navy as a Warfare Officer (Sub) and become a crew member of one of the T-boat fleet.
I notice on the RN website there is a link to a submarine rescue vehicle that can dive deep and hold up to 16 rescued crew. It is a mini-sub that has a crew of two and can carry a diver, if I remember correctly.
Do you happen to know if this vehicle (or others like it if you are answering from a foreign Navy) are operated by members of the Submarine Service? Or are they crewed by Navy personnel from other branches? Thanks!
Note: I believe this is part of the 'SUBSUNK' branch of the Royal Navy, if this helps.
You're looking at a DSRV: http://www.navy.mil/navydata/fact_display.asp?cid=4100&tid=500&ct=4
In the USN, it's operated by members of the Submarine Community with a GREAT deal of coordination with Aviation (the Air Force can fly the danged thing around the world).
The RN operates the LR5 Manned submersible:

http://en.wikipedia.org/wiki/LR5
I'm not sure who crews the LR5, but I would IMAGINE it is also crewed by RN personnel from the Submarine Service.
I'm a retired aviation kinda-guy and am standing by to be corrected by my brother's in the Bubble-head community.
DSRV's are NOT for SpecOps... those are SDV (Seal Delivery Vehicles) and are operated by Seals off of submarines: http://www.navy.mil/navydata/cno/n87/usw/issue_12/masters.html
