The Motor Ship Mount Washington

[BroadHopper]

Bit surprise to hear that they use concrete. Concrete is porous and loses weight when it is dry and can absorb moisture and gain weight. Are you sure they use concrete? In the maritime industry, one would pump or drain seawater from ballasts to maintain a certain level on a ship. The Mt would surely be a lot higher in the water caring no passengers versus a full load of passenger and crew if they can't change the weight of the ballast.

Also concrete being porous will rust out the steel hull. Unless the concrete is in a seperate container, but that will cause shifting in rough water.

If the Mt is flat bottom like a barge, then then changing ballast will be less significent problem than a boat with a round or V hull.

Does anyone know when the work is to be completed? Wish there were more pics of the progess too,like relocation of the web cam.

I was a bit surprised too. But, concrete has been used as marine ballast in steel hulls successfully. If the hull was prepped properly (sanded, epoxied, etc.) and the concrete is a higher PSI rating (5000+) and sealed after its cured, it should be okay for the next 100 years.

I'd be curious to know if it was straight 'crete, or if punchings were added to the mix.

That is a great video thanks for putting it up for all to see. I can only imagine a repower of this size and how much work and effort it takes. Nice to see that they are methodically tagging and cataloging all the parts and pieces.

I am sure that the parts and pieces from our M/S Mount Washington's Enterprise Engines will be sought after so as to keep some other vessel, vessels going on, that were not ready, as yet to give up the Enterprise Engines... Grants Help, as you and we all know.

Having lived in the Lakes Region for so many years and being a fan of our M/S Mount Washington, I am Soooo happy that they chose Caterpillar engines to replace the old Enterprise's, as they are the very best and most efficient engines that money can buy these days... When it comes to Diesel Power, they've had and continue to have a lock on it...

M/S Mount Washington is on Facebook and they seem to be doing a great job with the updates and pictures.

I agree, they do a good job. However I prefer winnipesaukee.com, as it adds some more sauce to the mix...

Concrete? Whatever happened to NH granite cobblestones?

Cats are good engines but they will require more preventive & corrective maintenance and overhauls then the old Enterprise engines. The old engines were very forgiving. The new Cats will require more tender loving care. In addition, the longevity of these new engines will be far less than that of the old engines. Parts & technical assistance will be available for the new Cats so that is a big plus. Personally, I will miss seeing the long block Enterprise engines.

Hi moose tracks, the Enterprise was one of the best engines ever built. I will miss them too. However, pound for pound and with the light of today so ever being on Green, the Cats will shine.
Chief Engineer Jim knows all about maintenance. Keep the intake air clean, (change filters), keep the fuel clean, (change filters), keep the oil clean, (change oil and filters and take an oil sample and have it analyzed to catch any ware or coolant leaks before they become a problem, kind of like a blood test for humans).

A little off topic, although in the Trucking and Heavy Equipment industry, Cat recommended a main & connecting rod bearing inspection @ 300,000 miles, or so many hours. I have seen Cat engines go well over a million miles without even a tune up, with proper maintenance.

I heard they were scheduled for sea trials in Mid April...and that they were on time.

Can't wait.I want to be out on the water to hear the old girl all freshened up with the new power plants.

Not to turn this into an ice-out thread, but it seems pretty clear from the recent weather that the lake will easily be open and ready by then.

[AltnBay]

For us with foolish imaginations!!!Here's a link of the Cat. C32's underway at full throttle. I almost fell outta' my chair laughing with images of a planed out 'Mount in the broards headed for Alton.

Once Winnfabs get a hold of this video, The Mt will be outlawed forever!

[robmac]

GREAT VIDEO , yup that'll leave one heck of a wake.

[OCDACTIVE]

Very nice! Beautiful engines. Given those were Jet Drives in that video on a Cat boat but definately a lot of power....

Those must be the 1600 HP variants. They trade HP for longevity.

Speaking of variants, I was looking at the Caterpillar engine brochure upthread http://marine.cat.com/cda/files/9627...ngine.pdf?mode and see that they go from 660 hp all the way to 1300 hp, holding RPMs constant at 1800, then up to 1600 hp @ 2300 RPM. This, all on the same displacement, with twin turbochargers?

Either the engines at the lower end, such as the 660s or the 750s in the Mount are going to last forever, or the 1600 hp units are really being pushed hard.

Question to those with experience with larger diesels such as these: Would the lubrication systems, internal parts such as pistons etc. be the same, or would things like the alloys used for identical-looking parts be different? Is the main difference simply in the injectors, turbo dump gates, and engine controls, plus a beefed up component list better able to take the heat and pressure or is it simply all done via engine controls and injection and turbo settings?

The Enterprise units did about 615 hp on something like 7 times the displacement of these new engines, though the former didn't have turbos I gather. That comparison, plus the differences in the C32 family itself, make for quite a range of power per unit displacement variations!

[Dave R]

I'm pretty sure that above a certain HP range, CAT puts 4 turbos on the C32.

My gut says they'd have to modify the cooling and oiling systems on the high HP engines, just to keep them cool. You can't run a 1900 HP cooling system on a 600 HP engine or it'll never get to the corrrect operating temperature and that hurts longevity more than higher turbo pressure or RPM. I think it would be safe to assume they'd use different pistons and valves in the high HP variants, and you can be sure the fuel system is different. I bet the rods, crank and block are the same.

The Electronic Control Module (ECM) is the "brain" or center of the C32 ACERTengine control system.

The ECM uses the information
gathered by the sensors
which are located throughout
the engine and transmission
to monitor all aspects of
engine operation.
Connected to the ECM by the
wiring harness, the sensors
detect and convert changes in
pressure, temperature or
mechanical movement into
electrical signals. The electrical
signals are sent to the ECM.
The ECM uses information such
as desired engine speed, and
load to determine the fuel
injection pressure, timing and
duration. Based on sensor
inputs, the ECM actuates the
individual unit injectors to
control engine speed.
The customer connector allows
the engine’s ECM to interface
with Caterpillar monitoring
systems or other manufacturer’s
monitoring systems. These
systems display engineoperating
parameters such as
speed, load, fuel consumption,
temperature, pressure,
maintenance and diagnostic
information, as well as trip
and historical data. Additional
switches, lamps, and optional
components can be installed
and linked to the customer
connector.
The service technician
communicates with the ECM by
means of computer, cable, and
service tool connector, to
perform diagnostic tests and

modify operating parameters.

I know she's an old girl, but wouldn't it have been great to go with the twin turbos! Maybe a little propane injection to quickly get up on plane, and yank the props for a couple of jet drives...
