Fred,

Thanks for the pointer to the additional pictures and info on Tug Urger.

You have some great shots there.

An additional question for you regarding how the compressed air start works:

•      For the first start of the day do there have a hand pump to build
  

up pressure in a tank?

•      What amount of air pressure is required to start the engine?
  

•      After the first start do they then use the engine to re-build air
  

pressure for the next start?

o  Say for a stop then to go into reverse?

Just curious.

As I recall, Urger uses about 120 PSI air pressure to start the engine.  They use a modern compressor and generator to keep things running these days ... which makes the engine room rather loud ... but the engine itself is very very quiet.

They are able to actually run the engine on air pressure without fuel ... comes in handy for docking.

Way back when, the main engine would be used to refill the air tank, but that system has been removed.
