The Motor Ship Mount Washington

dpg · 02-15-2010, 12:52 PM

That's a big Milton Cat Diesel(s) going into the Mount. Cat makes many a motor for tons of applications, I have a little exposure to them through work.

dmjr · 02-15-2010, 10:51 PM

What is going to be the fate of the old engines?

What is the horse power ratings of the new Milton Cat Diesels going into the Mount? I know that the old engines put out 615hp each.

Will the new ones have reverse gears?

Yes. Like the old engines, the new engines only go in one direction. However the new gearboxes, which connect each engine to a drive shaft, can be put in reverse while the engines are running. With the old gearboxes it took as long as 30 seconds to stop one/both engines, switch gears, and restart the engines.

As a side note, the new engines are much lighter than the old engines. Ballast will be added to the bilge to assist in stability.

Updated 03-MAR-10. After posting the above I was corrected. I had no idea that diesel engines could run backward. In doing some online research, reversing a bi-directional diesel engine is accomplished by shifting the gears on the cam shaft so that the valves open/close at a different time than when running forward. This requires bringing the engine to a complete stop before shifting the cam shaft. The diesel in my VW does not have this option, but then again, I can shift to reverse without stopping the engine.

Yes, that 30 second delay is probably responsible for a couple of near and actual groundings of the Mount. On a windy day, watching the Mount make its turn in Centre Harbor I watched it almost go ashore several times, and once into a boat house a couple of cottages down from us. Looks like that won't be happening anymore.

dmjr · 02-21-2010, 04:20 PM

I noticed a large I-Beam sticking out the side of the Mount. Have they started lifting out the old engines or are the installing the new ones? What will be the fate of the old engines?

Grant · 02-22-2010, 08:45 AM

I noticed that also. Will post a photo.

skprbob · 02-22-2010, 09:41 AM

Bizer & Pineneedles - The two outgoing Enterprise engines were direct drive; no gearboxes. To reverse direction, the engines were stopped, then restarted with the opposite rotation. The two new Cats do have gearboxes, so may be kept running and shifted much like an ordinary boat would. There will still be a delay in shifting to allow the propellors to stop rotating first. This will be shorter, since the new equipment will also include shaft brakes.

Grant · 02-22-2010, 12:01 PM

The I-beam protruding from the Mount's starboard side.

Bizer · 03-03-2010, 10:47 PM

Here are some photos that I took today...

I heard a bit on news 9 tonight about the Mount 'going green'... how does that factor in? Is that an initiative for all operations, or just the engine room?

I applaud the effort, wither way. I think every bit helps.

Just today, for a laugh to share, my 4 year old insisted that I get a cup with triangle on the bottom for him to drink from - so he knows that it was recycled. Now, I didn't teach him to be quite THAT insistent, but I support it! (They were both recyclable, but I got the one 'with the triangle' anyway.)

Reading today's LaDaSun article informs that the two old engines were two-stroke diesel w/ the crankshafts connected directly to the propeller driveshafts, so's going from forward to reverse required engines to be shut down and stopped turning before restarting, engaged in reverse direction.....in the old method.

The new setup now has either one or two transmissions as there are two, new Caterpillar 4-stroke diesels, so the ship can go from forward to reverse very quickly and without having to turn off the engine.

Are the new transmissions automatic or manual with a clutch pedal & stick shift, and how many forward gears? This is a serious question......thanks in advance.

Ya knows....those two old engines were extremely, extremely QUIET.....jeesh....they were so QUIET.....it will be very difficult for the new engines to be more quiet than the old engines......and could be that the new engines will be louder......time will tell?

Slickcraft · 03-04-2010, 08:36 AM

I have watched the Mount dock in Alton. After the final alignment a ways out the engines were cut off for a several seconds. Kind of eerie watching that silent glide waiting for the start-up in reverse. Must have made the crew nervous now and then knowing that a failure to restart would mean a crash but I never heard of that happening.
Now all they have to do is shift into reverse. What is the fun in that?

I think there was more than one occasion where failure to start did result in a mishap.

Seeing the M/S Mount Washington coming into berth at Weirs Beach many times that if there was ever a hick-Up in the drive-train that she'd have shoved us over into VERMONT!!

She will be greener and also With the new automatic transmission, forward reverse and the drive shaft brakes, I for one will feel much better from now on!

More than likely, the transmissions will be either be electrically (drive by wire), hydraulically, or cable/throttle actuated. I can't quite tell from the pictures if those housings on the rear of the engines are the transmissions. They don't need to be very big. Our island is repowering one of our ferries this winter and although a much smaller scale, the same project. The attached pics are cell phone pics so sorry for the quaility.

Just came by the Center Harbor docks a while ago and saw the rigging company unloading 2 Cat engines for the Mount.

NoBozo · 03-03-2010, 01:53 PM

The Mount Cam from yesterday still shows the truck unloading the engines. NB

EDIT: 2:38 PM Wed. I think the DATE on the Mount Cam is 24 hours behind.

dmjr · 03-03-2010, 05:12 PM

It looks like the engines came in for the Mount Washington since there was alot of activity in Center Harbor

dmjr · 03-05-2010, 07:13 PM

I just found this on the internet
