USS SPRUANCE (DDG-111) Update

From someone inside the loop, good news and concerning news - Admiral Adama is not happy:
DDG 111 and following ships in the class, as well those receiving the "DDG Modernization" package (DDG 51, 53, and more on the way) there is a new Machinery Control System with all new consoles (Universal Control Consoles (UCC) with flat plasma screens, pull-down menus, controlled with a ball tab and a keyboard. There are no buttons to push. These consoles replace legacy PACC, EPCC, and SCC consoles. The entire plant (yes, ALL of it), electrical and/or propulsion can be run from ANY location.

So far there have been few issues with the MCS of significance, just the occasional glitch you expect to have with any new system of this complexity. The Universal Engine Controllers (UEC) were in place years ago, with the UEC+ starting in DDG 102. The "plus" designation of UEC+ is for the addition of digital fuel control.

A few more details about the incident Friday:
-Ship's force was not operating the gear. (BIW has the engineering plant until ships force moves aboard next month).
- This was not a failure of EOSS, tagout, or procedures. True, BIW does not follow USN procedures, they are expert engineers who follow OSHA safety rules, and when they are underway, they follow merchant mariner engineering standards. No issues with them from a safety POV - BIW is a great shipyard.
-There were no injuries. Fire was fully contained in the exhaust uptake.
-Only minor damage. No impact on ship's schedule, training, LOA, or sailaway.
-Root cause analysis is still in being done.

Good thing this incident occurred in the shipyard where the experts are on new DDG's construction. Engineers from BIW, SUPSHIP Bath, NAVSSES, and appropriate vendors from General Electric (they own the GTEs), and Lockheed Martin (they own the UECs) are investigating this incident, doing data reduction, and figuring out what happened to each electron involved in the plant.

It could be a failed component, or perhaps a needed software/firmware fix. Thing about the DDG-51 program, the infrastructure is in place for rapid discovery, analysis of the best solution, development of the fix, and rapid distribution of that fix to all of the ships affected.
Things happen with new construction. It isn't the "oops" that matter - it is how you react to it. All indications are the BIW are doing this right.

  I know. I not only contacted the Press Herald and GAVE THEM your blog addy, but also the Times Record & Kennebec Journal.

  As was posted above, these guys are pretty much of a left bent and if it isn't finding fault with Governor LePage, or trying to find some scandal involving a conservative legislator, etc, they really aren't too terribly interested.

Can you even battle short touch screens?

Wouldn't one of the greater concerns being that there is little to no manual backup and redundancy in the flat screen navy? When the 1s and 0s get crossed - or worse, someone can't go and fiddle with the knobs and buttons?

(Trying this again, commenting system seems to be adding comments twice and deleting twice - see, 1s and 0s written by a programmer with a Big Gulp and Jotck itch).

Navy times gave it a couple of sentences...finally.

yes i read that.

and wonder of all wonders it coincides to a great degree with the discription of the incident that i heard from a civilian employee who worked within 100 yards of the happening. the only major difference was that i was under the impression that it happened about 1000. also i was unaware that there was a shift change mixed in.
