MTU SERIES 60 DIESEL ENGINE

The electrolysis issues have been well known on the LCS. The electrolysis has been eating the crap out of the jets, causing them to lose propulsion. One would expect that to happen when you use steel jets in an aluminum hull.

Cause of Failure
Commissioned in January 2010 and made mostly of aluminum, the LCS 2’s early deterioration was due to a design flaw. Corrosion was concentrated in the ship's propulsion system where steel impeller housings came in contact with the surrounding aluminum structure. When two dissimilar metals come into electrical contact, as they did in this case, those metals corrode at different rates. A cathodic protection system, which would have prevented this, was never specified for the ship and therefore never installed.

Like I said, Google is your friend, You have no real time value/ involvement or experience with this type of vessel but only what you might need to pull up online. Why don't you respond to my question of human nature of being wrong once in a Blue moon in lieu of defending a position that you only have read about? I see it time and again with you and I don't understand. You certainly have your niche on the under 100" management delivery thing although I always giggle at your "I do over 30,000 miles a year deal" since circumnavigating earth is 28,000 miles but hey, if you can run a sport fish or a Princess back and forth to NY enough times than you might get half of that mileage. I can admit when I'm wrong or over my head knowledge wise and have done so many times on this forum . Let's see some humble pie with you sometime OK?

I never said I do 30k miles a year,ever. I do 10-15,000 NM a year, each and every year and have since 2003. It's not very hard to do when you usually run yachts that cruise at 2o-35 knots, you do a lot of deliveries and owner trips, and a lot of daily captaining. Even a day of fishing (trolling) can be an easy 75 nm........7 knots for 8 hours= 56nm plus running in and out.

Can you prove to me otherwise??? That the LCS is a successful design and has completed numerous tours without incident??? Any of them? Every aspect of the ship has had major issues. Way over budget, Gearbox failures requiring a tow in, galvanic corrosion, crappy isotta generators (that I didn't even know about), issues with the gas turbines and diesel engine technology, too small a crew size for it's purpose. No, I don't have any personal experience with the LCS but I'm pretty damn sure you don't either.....unless you're currently in the Navy or working in a shipyard in Mobile....which I doubt either.....

Getting way off topic here but I would venture a guess that an ICCP system would wreak havoc on sensitive electronics used by the military in their hulls. If you look at photos of a Freedom class on the hard they're pretty well zinc'd .

Sure, Its been said that the Littoral class hasn't been a home run right out of the box but no 1st generation U.S. naval ship has ever been an instant success without revisions, Arleigh Burke class weren't instant success's out of the box. These are incredibly sophisticated machines to design, build and maintain. The amount of equipment and sensors aboard these ships is mind boggling right down to accelerometer transducers mounted on / in prime movers, gens, all pumps and motors, axial fans etc. (Vampire Syst.) to monitor frequency vibrations being transmitted through the structure to the surrounding waters. Passive hydrophone systems etc. hence no ICCP. The level of sophistication is numbing. We now need to move this conversation to a dedicated thread as this is miles away from Series 60 motors.

It's a complete FAILURE. Plain and simple.

Yet they can't detect a cargo ship that is about to run them over.

Your statement is ill-informed and sophomoric. Please stick to what you know. Cabos or Princess yachts. The U.S Naval investigators as well as NKK have both released their investigational findings on both incidents and if you would comprehend what you read in lieu of downloading short sound bites than you would know that both incidents were human error from lack of training and not technology failures. I'll not respond to your googled rebuttal. Good night my friend...

I've read both reports hours before writing this. Inexperienced and improperly trained crew- human error.
