Cool! What ship is this? Only one gas turbine? So it looks like gas flow through the engine is from stern to bow? And then the reduction gear output shaft goes back along the port side of the engine? (it's a little hard to see the layout) Do you have a waste heat boiler? Does it make superheated steam to run a turbine generator? I went to KP and worked with MEBA for about 5 years, now I'm working at a combined cycle power plant shoreside, gas turbines are crazy crazy powerful for their size and weight.
This is a twin screw/ turbine government design. Gas flow is from Stern to bow. No waste heat boiler it’s not optimized for economy. diesel generators. Chevron had turbo electric marine propulsion gas turbines but I don’t know of any others. They have been scrapped- not economic and old for tanker trade
Oh man it’s been awhile. You can google the specs for the LM 2500 power turbine speed can be 3,600rpm, propeller speeds are under 200 so somewhere between 20:1 and 15:1 would be my best guess
In German navy we had also GM2500 Gasturbines on board, was a diesel eating screaming monster, Really nice to hear her when in full speed. 😁
Love it! Retired BT/GSMC here... this is propulsionporn to me! Love it!

@@steamman9193 Watson Class?
I spent 2 years on a Spruance class destroyer and we had the same engines. But no window on the intake. Awesome to see.
@@fisidavethe Ticonderoga class were the 1st to have an inlet window. OHP's did not though
what's the reduction ratio
