I used to be assigned to USS LEWIS B. PULLER (FFG 23) which used two gas turbine engines for main propulsion. LM-2500 engines I think, same basic design as used in a DC-9 from foggy memory. 20,000 shaft horse power from each engine. Under normal operations, the Engineering Section began for getting underway 24 hours prior to casting off from the pier, but the gas turbine engines would not be lit off until an hour or so prior. In an emergency, that whole cycle could be compressed to about 30-45 minutes, and one of our Chief Engineer's bragged that he could take the engines from stone cold to ready for helm orders in 10 minutes if needed.
This compares to a steam plant which may take a full 24 hours just to be ready for helm orders, with limited ability to shorten that if the plant was stone cold. ------------- Max Charleston SC On Fri, Sep 11, 2015 at 1:07 PM, Craig via Mercedes <email@example.com> wrote: > On Fri, 11 Sep 2015 09:56:52 -0700 G Mann via Mercedes > <firstname.lastname@example.org> wrote: > > > So sorry to bring rain to the parade.. > > > > Reality is like that.
