Mr 'L' -
Many Thanks! Yes, in the past few days, saw a news clipping about the biggest MAERSK that ever was, running Far East - California.
Said to be in exclusive service for WAL MART inbound stuff! For a Container Ship, it is quick, and can make thirty-one (31) kts.!
In any case, the vessel has one of these massive motors...

That's a strong engine, all right....
If they ever made a marine version of this http://www.geaviation.com/engines/commercial/ge90/
I wonder how it would measure up?
They do make an LM6000 marine engine, but it is based on the much smaller CF-6 engine...... |

Ain't gonna' work, Magee! It has been tried, with SEA LAND SL-7 Container Liners. Not cheap to run. Shippers wouldn't pay the rates,
and so much for that! These Vessels now in a DoD Reserve Duty Fleet. They are quick! (Do a 'web Search. Abundant leads.)
The MOMMA MAERSK MONSTER? Guess that doesn't use a 13 Speed box? <G>

Agreed. For raw power, you can't beat a turbine, but in efficiency and economy for land and sea vehicles/vessels, the turbine is too thirsty.
Besides the examples you cited, there was the failed experimental car, bus, and truck turbines tried several times thru the years. And the cruiseship industry has come back to diesel's, after a few uses of marine turbines.
I was merely wondering how the GE90-115B's thrust would translate into shaft horsepower---a very complicated conversion to calculate, without simply doing a static and dynamic test to determine.... |

You noted, "...I was merely wondering how the GE90-115B's thrust would translate into shaft horsepower...". As you explained,
that would be expertise of the trained engineers who know how to do it. Clearly takes some good test equipment, too.
Stuff they do at the GE Plant...
Turbines in service on highway vehicles? Right! We're going back fifty years with the thinking. Right around 1960, several of
the "heavy" (Class 8) builders did much testing, and had units on the road. Seems to me GREYHOUND may have had some
test vehicles, too. When it was all over, no one was much satisfied with results. It did make the point of high fuel burn rates.
Sometimes, "latest, greatest thing" simply isn't better...
There are good files about this on HANK'S TRUCK PICTURES and HANK'S TRUCK FORUM. Also, accounts in some books recalling
the era. It just didn't work out, but it was needed to check whether a good option.

I was aboard Continental Trailways (American Buslines) Silver Eagle 29511 in May of 1969 when its Ford built turbine engine made it the "World's First Long Distance Turbine Powered Bus".
Veteran operator Don Martin was at the wheel as far as Pittsburgh, and the 20 or so passengers were accompanied by Company tech riders, officials, and the press. I rode it as far as Effingham, Illinois on its journey towards Los Angeles. I still have a souvenir keychain.
It was a failure, no more were produced.
A couple of years later Greyhound Lines tested an MC-7 powered by an Allison turbine. After a nationwide tour, it ran between its home garage in Detroit, and Indianapolis, Allison's plant location. A few years later, the US Department of Energy gave Greyhound and Allison a grant to build ten more MC-8 "Turbocruisers". These held down the schedules between Philadelphia and Washington for a couple of years, before they were converted to diesel operation.
Same problem......too thirsty. |
