I was a Gas Turbine Tech in the Navy - even pre-commished a cruiser at Bath Iron Works where this ship was built.
What shut this ship down was the most feared casualty to the main propulsion system that can happen: FUD (Fuk... Up Debris) in the main Reduction Gear Lube Oil System. The snipe on watch probably discovered it when he was cleaning the lube oil purifier soon after the ship got underway - a task I did so many times while I was in watch in the engine room. Not sure if the reduction gear locked up or if they just kept finding shavings and shut it down before the inevitable.
The main reduction gear is kept under lock and key because it would be so easy to incapacitate the ship by throwing something in there and in 99% of cases if something does go wrong with the reduction gear it's beyond the capacity of the ships personal to fix it. That's a job for the shipyard and the boys at Western Gear. http://youtu.be/YLQW2QJ_fzQ

Me too cleaned that thing countless times, always on the mid watch. I was a GSE on a FFG and I completely agree that it has to be a Main Reduction Gear failure it's the only thing that makes sense.
Looking back these ships are really quite impressive GE LM2500'S 20,000 -25,000 hp Gas Turbines depending on the ship that they are on. The main reduction gear is almost a work of art 9ft bull gear, double helical double reduction, 3600RPM input 200RPM output tolerances measured in the thousands of an inch. Pretty neat.

. Small world Questofpower. I was a GSM5 on the Stark, FFG 31. I got off of her right before she geared up for her deployment to the Gulf in 87 and was struck by that Iraqi plane. The week I got out of the Navy all of the Flags were at half mast in honor of the 37 sailors lost in that attack. I had been off her for 9 months but I knew over half of the sailors that were lost. The ones that lived went thru hell keeping that ship afloat and then were treated like **** by the Navy because I guess they somehow blamed them for letting her get hit.

I'll bet it had something to do with operating in salt water. Would never have happened if they'd have stuck to the lakes.

Yep, the good ole De Laval Lube oil purifier - had to clean every one of those dam 32 disks .
