What is the RedLine on a KTA?

 

Best that I can remember is somewhere between 2100 and 2600 depending on HP set up. Torque is up there. 1500+ftlbs depending on set up. Usually Tugs are set up for continuous duty at, let say 2100 rpm. That means they can run there all the time. The higher HP ratings are not continous duty ratings such as you might see in a speedy pleasure yacht.

Below is a sampling of hp and torque ratings for Oilfield stuff. This is the Common Rail Verion of the KTA 1150. QSK19 is the new name. That would be a big 4 Cylinder engine. Comes as a inline 6 also.

Here is a cold idling "K" if it works that is....

There's a Semi truck puller that I saw last weekend that had one of those, except the sticker on the side said 4000 hp!

 

I love a Cummins but it sure is hard to beat an old school Detroit with a strait pipe. I just cant decide if the V6 or V12s sounded better.

 

Man I remember that sound. Nothing smells better than a 71 in the morning!! My Cummins smells like a LPG Fork Lift or something.

That sounded like a 53 seris with all them hi revs.

Someone has built a Street Rod and used a 12V71 for the engine.

Here is a link to youtube for the Paula McCall. The first link is not that old as shes wearing someone else's colors. Just realized this is not the 145 footer. This is 190ft, renamed Paula McCall. Don't know what engines it has.

Edit; After seeing the newly named Paula McCall, I looked back and found out the original Paula McCall is now flagged in the Marshall Islands and is still in service, built in 1984. I was mistaken with the engine numbers. Its has five (5) KTA1150's. The US Flagged Paula McCall that is 190ft long is powered by five (5) KTA50-M2 Cummins Engines at 1800hp each. V-16's. 9000HP. The You Tube links below show it on Sea Trials. It's to bad the engines can't be heard on the Vids. Engine Data link;

That was actually a 6V92 in that video I linked. The 53s sounded sweet for sure! Lets see if I can find some 318 action here.

 

Got another one of that same tug....

 

well heres a nice 149 for the 2 stroke music. we;re making 1.6 mega watts on the load test here.

 

and heres pre commissioning the powerhouse for the new hospital in Calgary it has 10 - MTU 20v4000's. This is running no load. its a 3.2 megawatt genset at about 4400hp

 

to keep with the cummins theme heres a QSK50 I worked on a while back, 50 Liter engine. 2250hp oilfield spec. on a frac pumper with an Allison S9810 behind it.

big turbos

 

I see your performing a load bank test. During the last test I did before retiring we were required to take the unit (3516 Cat) up to 110% for a certain amount of time. Was this the case here also?

 

We took four(4) 3516's to 110% for 8 hours...
I got to see one of the first experimental C-175 Cat CRs get loaded to the hill at a testing facility near Peoria Il. years ago...
What an absolute beast..

 

that 149 is at 100% load for 2 hours. standby generators here is 100% to certify. but length of time depends on what the unit is in and powering. and also depends if its a commissioning or an annual.


The the 10 MTU's are 80 Liter engines each. with a total power output of 25 mega watts, not bad for a hospital standby. thats more than some of the smaller power stations on the grid.

 

You won't get an argument from me I put in two of them in for Data Center back up system which serviced a vast area of medical centers, quite impressive indeed!

Equally impressive! In both areas the doctors don't take being disappointed very easy, even more so when they have someone on their O tables....
