Does anyone know what this could be off?

Looks like the con-rod is a little bent, but the cross-head looks OK.

I assume youve seen one of these beast before then.

 

[gordon stephenson]

Aye, worked on lots of similar machines, but never come across a bend like that. There has been some serious power to do that, one of our larger electric motors was 23,000 HP,

After an overhaul or bearing change etc, we had to ring the power station to tell them when we were ready for a test run, only allowed 1 or 2 starts an hour, It used to take an age to come to rest after a solo test run.

what wattage was that motor im guessing around18 kw ?

 

[gordon stephenson]

Have not got a clue about the wattage, Electrickery is not my thing. just concentrated on the big mechanical rotating machines.
But 18Kw does not seem like anywhere near enough, Imersion heaters are 3Kw and some showers are over 10Kw,
Im sure some of our members will figure it out for us,
Maybe you meant Mw

Online calculator gives 17151.097 kW

 

[gordon stephenson]

Thanks Robotstar, So that is getting on for nearly 18Mw (isn't it)

whoops just did my calculation again and realise I read the display wrong I put 18kw that's only 8ish 3hp compressors

Not sure about a Wartsila, but the 900mm bore 9 cylinder I worked on as a cadet was producing about 6000 bhp per pot at full power.

I it was a ship, wonder if the Captain felt it on the other end of the ship? What the HECK was that?..................

Probably didn't feel much due to the mass of metal in the ship?, some years ago I was on a tram that hit a car, just felt like the wheel had bumped over a small stone until we stopped and someone said we've hit a car!

Pushed it about 30 metres before we could stop

Would that have been a sulzer RND 90 per chance, size and power sounds about right. Fond memories, of tightening tappets when running at 20 rpm, hangovers from hell and dusky maidens in brazil. I was once a cadet too!

18mw is a big motor, had 7, 10mw jobs last place I worked, but we were also the power station, lights used to dim when they span up.

Burmeister&Wain, or rather MAN B&W these days and it was a licence-built one as most are, by Hyundai if my memory serves me correctly. 9K90MC-C rated at 42MW, hieroglyphics which mean 9 cylinders, short(2300mm!) stroke, 900mm bore, compact(shorter overall relative to the standard engine layout), camshaft controlled fuelling. She went through 150 tonnes of heavy fuel oil per day at 25 knots on trials, but most of the time we were doing 22-23 knots at 120 tonnes/day.

 

[addjunkie]

Hyundai been there a few times, quite an interesting experience, for new builds. That sounds like it was a box boat or reefer at those speeds. I was on the slow boat from hell until i decided going to sea was for fools and fish.

Zim boxboat crewed by Zodiac; interesting experience but my primary learning point was that I never wanted to work on another container ship.

I Worked for Sulzer and MAN, Great machines,

Guess you must be younger than me, In my day zim line was all foreign flag, and the use of manning / front companies was only just starting out. i also cant imagine rattling from container terminal to container terminal for 12 hour discharges much fun either.

Going to sea was about work hard play had, partying in port, and doing things youd not tell your mother about.

This I would agree with, well engineered, compared to some of the stuff Ive seen in the oil industry in recent years.

 

[gordon stephenson]

I have been finished with all that heavy stuff 13years now, Just had to blow 71 candles out on the birthday cake.

This is 8 years ago now, the trend then and now is bigger, bigger, bigger; I was uncomfortable with the number of potential single-point failures there were in the ship's systems and design and the boat I was on was about average then at 4500 TEU, i don't imagine things have changed since. In the absence of any ability to influence the design of them I can only choose to not work on them.
